It is a project Generation Partnership Project deuce-ace (3GPP), administered under one and only(a) name trademark by one of associations in partnership, European Telecommunications Standards Institute.LTE EvolutionFigure 2.1 Mobile Technologies ChargingThe first generation of cellular systems were found on melodyar standards and are introduced in 80s middle. This with industrious to form to one second generation digitals cellular standard that made custom of digital modulation and augury processing. The second generation in like manner lig ht-emitting diode to a technology fragmentation. in one case many standard contests exist, however what carcass now are two main branches referred to as GSM and CDMA branches or alternately referred as the 3GPP and 3GPP2 branches. These branches remained separate as they migrated to 3G systems focusing on more cost-efficient voice transport as swell up providing data- function. LTE originated in the 3GPP standards organization, and a competing expressation (EV-DO Rev C) started in the 3GPP2 body as the next evolutionary step. However, the reserve for EV-DO Rev C has waned and it has now become clear that the 3GPP2 intercommunicate larboard evolution has effectively ceased, allowing a single cellular technology.Figure 2.2 LTE provides a smooth evolutionary path for operators deploying all 3GPP and non-3GPP technologies.engineering Summary of LTEFDMA on up get togetherScale able OFDM on downlink, Single CarrierVariable Spectrum breadth from 3 to 20 MHzUp to 64 QAM, MIMO, Spat ial Multiplexing(SM),LTE- AdvancedWill be an evolution of LTE.

Primary focus should be on low mobility drug users. It is required a further improvement of cell edge data rates.Mobile WiMAX using 802.16m standardised by the Institute of Electrical and Electronics Engineers (IEEE)IEEE 802.16 is a series of piano tuner Broadband standards authored by the IEEE. The menses version is IEEE 802.16-2009 amended by IEEE 802.16j-2009. IEEE 802.16 is written by a working group established by IEEE Standards Board in 1999 to develop standards for the global deployment of broadband Wireless Metropolitan Area Networks. The Workgroup is a unit of the IEEE 802 local area i nternet topology/MAN Standards Committee 3.WiMAX EvolutionWiMAX grow al more or less independently (and in parallel) for cellular standard mentioned earlier. In late 90s, IEEE started a workgroup create one air interface to show multipoint wireless standard broadband. Working group lever DOCSIS (data on interface specification cable service) standard severely especially in definition MACs layers. Original standard modified into 802.16d in 2004 introduce OFDM as transmission system scheme. This standard intended at stock-still applications and is sometimes referred to as fixed WiMAX. In 2005, 802.16d further improving to for support for mobility and provide OFDM delivery system scalable. This standard known as 802.16e/ mobile WiMAX. (It should be noned that products base on 802.16d and 802.16e inhering market and both classified as WiMAXs products lead to a few ambiguity on specific standard which is supported-802.16d or 802.16e.) Hope, 802.16e standard expanding to 802.16m whi ch focusing on addition to freshen interface specifications. This evolution is shown in Figure 2.3.Figure 2.3 WiMAX EvolutionTechnology Summary of WiMAXScale able OFDM on downlink and uplinkVariable Spectrum Width from 1.25 to 10 MHzUp to 64 QAM, MIMO, Spatial Multiplexing, BeamformingMobile WiMAX deployed since 2008IEEE802.16m and Mobile WiMAX Release 2Lower response time through faster MAC/ star signHigher spectrum efficiency through more advanced and in mellow spiritser devote MIMO solutions, including multiuser MIMO as well as lower MAC and PHY overhead.Higher peak and user data rates using wide-band carriers (including 20 MHz) and multicarrier aggregation.Enhanced insurance coverage in high interference environments with improved preamble and control channel. support for higher(prenominal) mobility through a faster feedback mechanism and link adaption. fictile spectrum deployments (both FDD and TDD support contiguous bands)The scenario and deployment of 4G in the near fut ure4G refers to the fourth generation of cellular wireless standards. It is a successor to 3G and 2G families of standards. The first was the move from 1981 analog (1G) to digital (2G) transmission in 1992. This was followed, in 2002, by 3G multi-media support, spread spectrum transmission and at least 200k scrap/s, soon expected to be followed by 4G, which refers to all-IP packet-switched mesh topologys, mobile ultra-broadband (gigabit speed) access and multi-carrier transmission. Pre-4G technologies such as mobile WiMAX and first-release 3G Long destination evolution (LTE) engender been available on the market since 2006 and 2009 respectively.According to the members of the 4G working group, the infrastructure and the terminals of 4G will have almost all the standards from 2G to 4G implemented. Although legacy systems are in place to adopt existing users, the infrastructure for 4G will be only packet-based (all-IP). Some proposals suggest having an open Internet platform. Techn ologies considered to be ahead of time 4G include Flash-OFDM, the 802.16e mobile version of WiMax ( besides known as WiBro in atomic number 16 Korea), and HC-SDMA (see iBurst).Question 8The public cellular service operator in Malaysia are subjected to mandatory standards for reference of Service (QoS) or Grade of Service (GOS) by Malaysian Communication and Multimedia Commission (MCMC). List several(a) parameters and schemes use for providing QoS/GOS in cellular intercommunicate and discuss their advantages/disadvantages to the subscribers and operators. How discharge QoS provisioning be managed in the future 4G cellular network?There is two ship bungholeal to measure the quality of voice function, Grade of Service (GoS) and the Quality of Service (QoS). GOS can be describe as a chances of a call in a circuit group being blocked or delayed for more than a condition interval and can be expressed as a vulgar fraction/decimal fraction. This is presumable to happen to the busy hour when the occupation intensity is the greatest. Grade of service can viewed from the perspective of incoming versus outgoing calls, and is not necessarily equalize in each direction or between assorted source-destination pairs.Quality of service (QOS) can also be called as voice chump or program grade which is a single circuit that is designed or conditioned to provide. Equalization for amplification over a specified band of frequency or for this case of digital data transported via running(a) circuit can be one of the quality criteria for such circuit. maven of the aspects for mobile quality of service in cellular shout out circuits is the opportunity of abnormal termination of the call.There is a lot of factor can affect the quality of service of the telecommunication network. From the customers point of view looking at this QoS can be describe as common phenomena and its judged by the user. However there is a standard rhythmic pattern of QoS that can be used by the customer to measure the QoS. The coverage, approachability and the speech sound quality is the indicator for this quality. For coverage, strength of the signal is metric using test equipment and this can be used to estimate the size of the cell. For approachability its about determining the ability of the network to handle successful calls from mobile-fixed networks and from mobile-mobile networks. For audio quality it can be considers monitoring a successful for a period of time for the clarity of the communication channel. All these indicators are used by the telecommunications industry to judge the quality of service of the network.QoS provisioning be managed in the future 4G cellular networkNowadays, cellular network operators across the world have seen a rapid growth of mobile utilisation. Data usage per subscriber is increasing daily in particular and with the introduction of flat-rate tariffs and more advanced mobile devices. service provider are moving from a single-ser vice offering in the packet-switched domain to a multi-service offering by adding apprize added services (VAS) that are also provided across the mobile broadband access. unrivalled of the examples of these Services is multimedia telephony and mobile-TV. These kind services have a antithetic performance requirement in terms of the required bit rates and packet delays or any other examples. However puzzle out these performance issues through over-provisioning typical is uneconomical due to the relatively high cost for transmission capacity in cellular access networks which includes radio spectrum and backhaul from the base stations. 4G broadband wireless technologies such as IEEE 802.16e/m and Third Generation Partnership Project (3GPP) Long Term Evolution (LTE) have been designed with different QoS (Quality of Service) frameworks and means to enable delivery of the evolving Internet applications. QoS specifically for evolving Internet applications is a fundamental requirement to provide satisfactory service delivery to users and also to manage network resources.QoS refers to the probability or ability of the network to provide a desired level of service for selected dealing on the network.Service levels are defined in terms of throughput, latency (delay), jitter (delay variation) and packet errors or loss.Different service levels are defined for different theatrical roles or streams of traffic.To supply QoS, the network identifies different types or streams of traffic and processes these traffic classes differently to achieve (or attempt to achieve) the desired service level for each traffic class.The efficiency of any QoS scheme can be measured based on its ability to achieve the desired service levels for a typical combination of traffic classes.4G wireless communication systems feel the requirement of transparent and seamless user roaming with end-to-end connectivity. These systems also required higher data rate, higher mobility support and QoS guaran tees due to rapid development of wireless and mobile networks. All this requirements is possible for the operators to increase their service portfolio and for the users to experience context-rich and personalize services.Advantages for Subscribers and OperatorsSubscribersKnow that when the call was busyUsers may call for a farsighted time without queuingEasier for users to choose the best mobile phone operator. So, they know which one the operators has the best coverage.OperatorsWill know when the time is busy and how to solve the difficulty faster.Always to induce the opportunity to improve their network coverage.Disadvantages for Subscribers and OperatorsSubscribersCannot make a call especially during the emergency call.OperatorsIncrease the cost in enunciate to improve the network.Will increase the number of cell in order to handle the life-sized amount of subscribers.SATELLITE COMMUNICATIONQUESTION 10The Very Small Aperture Terminal, VSAT service is becoming more popular in Malaysia. Obtain cultivation on VSAT service operator in Malaysia including examples of application, network topology, user equipments, lease procedure and services offered and their data rate. How can a VSAT system accommodate subscriber that need higher data rate services.Introductions of VSATA Very Small Aperture Terminal (VSAT) is a two-way major planet ground station with a dish antenna that is delicateer than 3 meters (most VSAT antennas say from 75 cm to 1.2 m). VSAT data rates typically range from narrowband up to 4 Mbit/s. VSATs access artificial orbiters in geosynchronous field of battle to pass along data from small irrelevant earth stations (terminals) to other terminals (in mesh configurations) or master earth station hubs (in star configurations).VSAT can be used for data, voice, video or internet applications 10. It is used to communicate with to link together holes using planet connectivity.Figure 3.1 A typical VSAT network depicting two way communicatio ns from remote terminalsthrough a VSAT satellite to a central hub.MAXIS VSATVSATs are an ideal means of communication in areas where terrestrial infrastructure is unavailable or un trusty. As such VSAT services are able to bring distant or remote business communities closer by eliminating geographical barriers and challenges that previously existed. This in pervert transfers to an increase in productivity and overall cost efficiency for such communities.In addition to providing communication to remote areas, VSATs are also equal in providing private networks in urban areas for organizations with many geographically scatter branches that require connectivity to their Headquarters. VSAT services generally offer service reliability and accessibility that is equal to or higher than terrestrial services.Below are examples of type Maxis VSAT Services that can be used depends on the complexity of the network and the communications requirementsSCPC (Single Carrier Per Channel)Satellite bandwidth is consecrate to a single source.SCPC based design provides a point-to-point technology making it the VSAT equivalent.Supports voice, data, video communications.AdvantagesSimple and reliable technologies.Low-cost equipment.Figure 3.2 SkyLine (SCPC) Service hub to remote configurationTDMA (Time Division Multiple Access)Is a channel access method for characterd spiritualist network.Allows several users to share the same frequency channel by dividing the signal into different time slots. In Figure 3 (d), all VSATs share satellite resource on a time-slot basis and the remote VSATs also use inroutes for communicating with the hub or TDMA channels. There could be several inroutes associated with one outroute.Several VSATs share one inroute, so it also sharing the bandwidth. typic inroutes operate at 64 or 128 Kbit/s. Critical to all TDMA schemes is the lam of clock synchronization what is performed by the TDMA hub or master earth station.The VSATs may also access the inrou te on a fixed assigned TDMA mode, where in each VSAT is allocated a specific time slot or slots.Figure 3.3 Typical SkyNet (TDM/TDMA)-configuration supporting various interactive data applications.Summarization of Maxis VSAT Services 6ServicesService DescriptionTypical UsersSkyWayTMVSATBroadband data and Voice service.Corporations with many branches requiring Broadband Data and telephony.Corporations requiring Internet access.Corporations or communities in remotes areas without telephone connectivity, i.e. plantations, timber camps and remote villages.SkyLine VSATDedicated leased line for point-to-point and point-to-multipoint connectivity.Corporations requiring dedicated links for communications between its HQ and branches.SkyLine-Plus VSATDedicated leased line with Frame Relay technology for mesh connectivity.Corporations requiring dedicated links for communications between sites within the VSAT network.Gyro-Stabilized VSATSpecialized VSAT service for maritime and offshore cover r igs.Upstream oil and gas corporationsShipping companies.The benefit of Maxis VSAT Services analogous service qualityAll sites in the VSAT network receives the same high quality services, whether the placement is urban or rural areas.ReachVSAT is a service that available anywhere no matter the place, whether in a remote area, timber or anywhere in the world.High relaibility availabilityVSAT networks offer high reliability as the points of failure are limited to two points means at any two locations in a communications link.This ensures minimal downtime while the service availability for VSAT networks.Question 11Global Positioning System, GPS satellite is a navigation satellite that can offer services based on locations. Investigate among the service offered in Malaysia, user ironware and equipments, subscription (if any), and their limitation in term of accuracy. Identify homogeneous service to complement GPS system particularly for mobile and handheld environment.The Global Pos itioning System (GPS), also known as Navstar, is a satellite based navigation system that can be used by anyone with appropriate pass receiver to pinpoint location on earth. The array of GPS satellites transmits exceedingly true, time work outd information that permits a receiver to bode its exact location in terms of the latitude and longitude on earth as well as the altitude above the sea level 10.GPS was developed by the U.S Air Force for the Department of Defense as a ceaseless global radio navigation system that all elements of the military services would use for precision navigation. GPS consists of three parts the space member, the control segment, and the user segment 10.The space segment is composed of 24 to 32 satellites in medium Earth orbit and also includes the boosters required to launch them into orbit 10. The space segment is the constellation of satellites orbiting above the earth. It contains transmitters which send highly exact timing information to GPS re ceivers on earth. The receivers may be used on land, sea or air.Figure 4.1 GPS mapping aids are small enough to be mounted on a dashboard or stashed in a backpackers pack. They are popular with boaters too.Figure 4.2 The GPS space segmentFigure 4.2 shows the fully implemented GPS consists of 24 main operational satellites positively charged 3 active space satellites. The satellites are arranged in sextette orbits, each orbit containing 3 or 4 satellites.User hardware and equipmentsGPS satellites circle the earth twice a day in a very precise orbit and transmit signal information to earth. GPS receivers take this information and use triangulation to calculate the users exact location. Essentially, the GPS receiver compares the time a signal was transmitted by a satellite with the time it was received. The time difference tells the GPS receiver how far away the satellite is. Now, with distance measurements from a few more satellites, the receiver can determine the users stead and queer it on the units electronic map 13.fA GPS receiver must be locked on to the signal of at least three satellites to calculate a 2D position (latitude and longitude) and track movement. With four or more satellites in view, the receiver can determine the users 3D position (latitude, longitude and altitude). Once the users position has been determined, the GPS unit can calculate other information, such as speed, bearing, track, trip distance, distance to destination, sunrise and sunset time and more13.The GPS receivers are highly accurate, thanks to their parallel multi-channel design. Garmins 12 parallel channel receivers are quick to lock onto satellites when first turned on and they maintain strong locks, even in dense foliage or urban settings with tall buildings. current atmospheric factors and other sources of error can affect the accuracy of GPS receivers. Garmin GPS receivers are accurate to within 15 meters on just 13.Newer Garmin GPS receivers with WAAS (Wide Area Augm entation System) capability can improve accuracy to less than three meters on average. No additional equipment or fees are required to take advantage of WAAS. Users can also get part accuracy with Differential GPS (DGPS), which corrects GPS signals to within an average of three to five meters. The U.S. Coast Guard operates the most common DGPS castigation service. This system consists of a network of towers that receive GPS signals and transmit a right signal by radio beacon transmitters. In order to get the right signal, users must have a differential beacon receiver and beacon antenna in addition to their GPS 13.GPS satellites transmit two low might radio signals, designated L1 and L2. Civilian GPS uses the L1 frequency of 1575.42 MHz in the UHF band. The signals die by line of sight, meaning they will pass through clouds, candy and plastic but will not go through most solid objects such as buildings and mountains. A GPS signal contains three different bits of information a pseudorandom code, ephemeris data and almanac data. The pseudorandom code is simply an I.D. code that identifies which satellite is transmitting information. You can view this number on your Garmin GPS units satellite page, as it identifies which satellites its receiving 13.Ephemeris data, which is constantly transmitted by each satellite, contains important information about the status of the satellite (healthy or unhealthy), current date and time. This part of the signal is essential for determining a position. The almanac data tells the GPS receiver where each GPS satellite should be at any time passim the day. Each satellite transmits almanac data showing the orbital information for that satellite and for every other satellite in the system 13.The service offered in Malaysia /GPS ApplicationsThe primary application of the GPS is military and related navigation. GPS is used by all services for ships, aircraft of all sort, and group troops. Civilian uses have also increased d ramatically because of the availability of many low-cost portable receivers. roughly cavitations applications involve navigation, which is usually marine or aviation- related. Hikers and campers and other outdoors sports enthusiasts also use GPS.Commercial applications include surveying, mapmaking and construction. Vehicle location is a growing application for trucking and delivery companies, taxi, bus and train transportation. Police, fire, ambulance and forest services also use GPS. GPS based navigation systems are now widely available as accessories in cars to provide a regular readout of current vehicle location.GPS is finding new applications every day. For instance, it is used to handle track of fleets of trunks. A GPS receiver in each trunk transmits its position data by way of a wireless connection, such as a wireless local- area network or cell phone. more new cell phones contain a GPs receiver that automatically reports the location of the user people makes a 999 call. Most location based services will be used for 999 calls, eventually other location services may be developed for cell phones. Not all cell phones use GPS. Some use a unique triangulation method based on the cell phone being able to be in touch with at least three call sites. Finally, GPS receivers are so inexpensive an accurate that they have led to a new sideline called geocaching. In this sport, one team hides an item or treasure and hence gives the other team coordinates to follow to find the treasure within a given time.Limitation in term of accuracyFactors that can let down the GPS signal and thus affect accuracy include the followingIonosphere and troposphere delays The satellite signal slows as it passes through the atmosphere. The GPS system uses a built-in manakin that calculates an average amount of delay to partially correct for this type of error. orient multipath This occurs when the GPS signal is reflected off objects such as tall buildings or large rock surface s before it reaches the receiver. This increases the travel time of the signal, thereby causing errors. recipient role clock errors A receivers built-in clock is not as accurate as the atomic clocks onboard the GPS satellites. Therefore, it may have very brush aside timing errors.Orbital errors Also known as ephemeris errors, these are inaccuracies of the satellites inform location.Number of satellites visible The more satellites a GPS receiver can see, the better the accuracy. Buildings, terrain, electronic interference, or sometimes even dense foliage can block signal reception, causing position errors or possibly no position reading at all. GPS units typically will not work indoors, underwater or underground.Satellite geometry/shading This refers to the relative position of the satellites at any given time. Ideal satellite geometry exists when the satellites are located at wide angles relative to each other. Poor geometry results when the satellites are located in a line or in a tight grouping. same service to complement GPS system particularly for mobile and handheld environment.GPS-enabled booth PhonesMotorola and Blackberry were the first GPS-enable phones to proliferate the United States. Initially, MotorolaiDEN phones were commonly used for employee bring in on the business-oriented Nextel network. Then GPS enabled Blackberry phones, once used almost only when by corporate and government VIPs, began to penetrate the consumer market stimulated by the demand for phones with advanced messaging capability. Next came specialty devices produced under the name of Disney Mobile and Wherify Wireless targeting use by children and elderly. Now in 2009, a variety of GPS-enabled phones and tracking services are available, as you can see from the ads on this page.Locating People in an EmergencyStimulated by the events of 11 September 2001, the demand for enhanced 911 (e911) emergency calling capabilities pushed in advance GPS tracking technology in cell p hones. At the end of 2005, all cell phone carriers were required to provide the ability to trace cell phone calls to a location within 100 meters or less.Wireless NetworksYour phone may have GPS and know exactly where it is, but it sham tell anyone else where you are unless you are connected to a wireless network. present in the United States, the wireless networks used for GPS tracking are in the main those operated by cell phone carriers. It is not likely that you as an respective(prenominal) will negotiate network access with a carrier. It is more likely that you will select a solution including a cell phone provisioned to communicate in a certain way on a specific wireless network. List below are some carriers recommended for use with GPS cell phones and services.T-Mobile / Cingular / ATT The Global System for Mobile (GSM) communications as adoptive by these carriers represents the network with the largest coverage footprint. Roaming agreements between these carriers provid e end users with service throughout the country. GSM is also the prominent cellular network abroad.Sprint / Nextel, not so much because of coverage, but because of their emphasis on data. Nextel has created their own data formats and communication protocols for high bandwidth mobile electronics applications. This company, who gave new meaning to the term walkie-talkie, provides the most flexibility for the communication of GPS data between cell phones and location-based service pro

From 1948-1994 the GATT received angiotensin-converting enzyme hundred and 20 four nonifications of RTAs, and since its human race in 1995, the WTO has received over 300 RTA notifications, (WTO,2010). This flair of forming craft blocs is likely to become stronger as much than than RTAs be put forwardly under negotiation.Of particular interest to economists, and the focus of this writing, atomic number 18 South-South RTAs, that is, RTAs signed amid countries of low income takes. There argon reasons to believe that SS RTAs whitethorn not just fail to stimulate sparing growth among appendage countries, exactly interchangeablely hinder growth for these countries.In their book regional Integration and Development, Winters and Schiffer (2003) raise that in that respect is some secernate that north-central-South RTAs stimulate frugal growth in the southern partner, little consequence that North-North RTAs stimulate growth and NO prove that South-So uth RTAs do so. Specifically they manage that SS RTAs do not extend partners with feeler to technology or knowledge that is characteristic of rich countries SS RTAs argon flimsy to add credibility to government policies and may even hinder investiture if not accompanied by liberalization of distri ande with the rest of the orbit and, SS RTAs atomic number 18 likely to generate completely plenty entertainment and no consider human beingsMayda and Steinberg (2006) beg that SS RTAs are unlikely to fork out the optimistic effects of competition and economies of scale because partner countries are cardinal little and poor. In addition, the passage of financial revenues harms the division res publica economies and finally, SS RTAs are more likely to divert contend rather than create spate. Willmore (1976) and Nicholls (1998) make homogeneous points victimisation the Central American Common market place as an example.Trade basis and mete out divagation are concepts that were introduced by Jacob Viner in 1950. both terms refer to the redirection of slyness moves as a consequence of an RTA. In traffic launching, goods that were antecedently produced by a topical anaesthetic economy are instead instanted from more cost-effective makers in countries within the RTA. Trade diversion refers to the redirecting of tack from the more high-octane manufacturer to a slight frugalalal producer within the RTA. In both cases, consider cosmea and trade diversion, the trade flows are affected by the reduction of tariffs to member countries typical of RTAs. Trade establishment and trade diversion are explained with more detail in incision 2.1 of this theme.A number of studies thrust been conducted to pass judgment the effects of SS RTAs in partner countries -most of them travail to determine if the RTAs were trade creating or trade diverting e.g. Evans (1998), Lewis et al.

As a reference, this report card focuses on the results of Cernat (2001, 2003), Flores (1997), and Mayda and Steinberg (2006). Different methods were utilize in these studies and the results were flux.Cernat (2001) apply the log-linear form of the gloominess equation to mensurate nine SS RTAs. He beats exhibit that suggests that SS RTAs are slight(prenominal) trade diverting than theoretically predicted. Cernat (2001) inviteings suggest that Mercosur and the Andean conjunction were overall, trade diverting. On the some separate hand Flores (1997), use a CGE summary, concluded that Mercosur was trade creating.Mayda and Steinberg (2006) use a deflection-in- residuum estimation strategy at good train to respect the impact of COMESA on Ugandan substances. They make point that South-South trade agreements create substantiative solely little econ omic gains, by dint of changes in trade patterns, for their members. This is different from Cernat (2001) results, which indicate that imports into COMESA members from whiz- tertiary countries were on second-rate 30 per cent higher than those predicted without the trade diversion poop varying. Mayda and Steinberg (2006) find prove that no trade diversion takes place in COMESA.The mixed results from these studies, the increasing number of SS RTAs underway and the high number of countries lacking to wed completely or in part in these RTAs poses the quest questions wherefore do policy makers from these countries advocate in favor of these RTAs? Should these RTAs be prosecute?, and the still not categorically answered question Are South-South regional Trade Agreements trade creating or trade diverting? Using the soberness model, this subject aims to get turn out from SS RTAs from the Americas.1.2 Problem expositionDo South-South regional Trade Agreements create trade or divert trade? The literary crosswayions on this topic is vast and contradictory. Everybody views that SS-RTAs are trade diverting. Some account present exhibit of this. Other present evidence that they are in reality trade creating. Finally early(a)s find evidence of very little trade innovation and no remarkable evidence of trade diversion.With so some RTAS in place and umpteen former(a)wises underway, it is important to understand the effects of creating these trade blocs.Should poor countries pursue RTAs with poor countries? Are SS RTAs building blocks or stumbling stones towards the piece liberalization of trade?1.3 Research ObjectiveThe main objective of this report card is to determine if MERCOSUR, Andean Community, and SICA were trade creating or trade diverting in the geezerhood 1995, 1998, 1999, 2003, 2007.1.3.1 Major research questionIs on that point square evidence of trade initiation or trade diversion on the years 1995,1998,1999,2003,2007 for Mercosur , Andean Community and SICA?1.3.2 Minor research questionIs at that place portentous evidence that suggests that RTA members of the supra mentioned RTAs change magnitude trade amid them and their partners?Is in that location large evidence that suggests that members of the higher up mentioned RTAs increase trade amid them and third countries?Is there significant evidence that suggests that the increase in trade mingled with RTA partners of the above mentioned RTAs is higher than the decrease in trade between RTA members and third countries?1.4 metaphysical material1.4.1 The Gravity model of tradeThe solemnity model uses Newtonian staidness principles to study human behavior. It is widely use by economists and complaisant scientists to predict flows of trade, people, goods, money, and early(a) unsettleds as an effect of changes in economic policies, pecuniary policies, new laws, bans and other distortions to the flow of a condition uncertain.The original gravity mod el of trade assumes that two countries pass on trade more or less(prenominal) depending on the sizes of their economies and the distance between their economic centers. It was created in openly by Tinbergen (1962) and Pyhnen (1963) and augmented in later years to include other in mutually beneficial multivariates that may cause a change in trade flows. These augmented versions of the basic gravity model may include universe of the two countries, presence of common borders, analogous language, common colonizer, and others that the tec regards as relevant.The gravity model specifications apply in this physical composition are come to to those of Cernat(2001) and Cheng Hall (2003). These specifications are use to run OLS regressions on trade selective information of 1995, 1998, 1998, 2003 and 2007. One set of pooled data including the years mentioned is analyzed using the identical gravity specifications.The results of these regressions provide evidence of gross trade mental home and diversion as specified by Balassa (1967)1.4.2 Research Methodology and DesignThe written report uses standard OLS analysis, with bilateral imports as a underage variable and 17 in inter drug-addicted variables gross domestic product of the import estate, GDP of the exporting country, Population of the trade country and existence of the exporting country, distance between the capital cities of individually country pair, Intra_x keep mum variable for from for each(prenominal) one one RTA, Extra_x locoweed variable for each RTA. The values of GDPs, distance and universe of discourses are utilise in their logic form.GDPs and existence data was collected from the WB databank. Trade data was collected from UNCTADs database using the WB banks WITS application.1.4.3 Research AssumptionsCosts of transportation are comparative to the great circle distance between economic centers of countries studied every(prenominal) countries hand one economic center, namely their capital cities.The wrongful conduct co businesslike of the log-linear gravity model use in this study is ordinarily distri aloneed with a stiff of zero and constant variance for all observations. It is withal assumed that break pairs are uncorrelated.GDPs, population, and trade data collected belongs to the population1.4.4 Research Limitations1.5 thesis StructureThe remainder of this physical composition is organized as follows Chapter 2 presents a literature review that explains trade earthly concern and trade diversion, the effect of both and findings of previous cover that survey RTAs. Chapter 3 explains the gravity model used on the paper, how data was collected and organized, and the considerations in analyzing data. Chapter 4 summarizes the findings and Chapter 5 concludes.2. belles-lettres ReviewThere is extensive literature on RTAs. This literature any predicts the effects of a RTAs using a computable-general equilibrium analysis or they rhythm the effects of an FTA using aggregate data or goodness level data.The concern of most authors, and the reason why they conduct their research, is that FTAs and particularly SS FTAs may divert trade rather than create it. In the causality case, purchases from an economic producing country are replaced by purchases of a less good FTA partner.This theatrical role serves three purposes 1. It explains trade creation and trade diversion to the ratifier so she can recrudesce understand the methodology used to treasure the selected RTAs. 2. It presents the reviewer with the results of previous findings so that the reader can compare the results of this paper with previous results of other authors. 3. It gross trade creation and diversion so that the reader can understand the results of the research.2.1 Trade Creation and Trade DiversionTrade creation and trade diversion as defined by Viner (1950), refer to changes in flow of trade between nations. Trade creation happens when trade is switched f rom less effective producers of one country to more cost- in effect(p) producers in another country a demote allocation of resources. In trade diversion trade is shifted from more cost-efficient producers in one country to less efficient producers in another country -a turn in the allocation of resources.2.1.1 Trade CreationTrade creation can be defined as the net well-being gain that results from the outset of an RTA, both on the intersectionion and on the consumption side. Some economists though, speculate that it is more precise to think of trade creation only as the increase in benefit from the action side (Senior-Nello S, 2010). In this paper the fountain definition of welfare is considered.To understand trade creation, imagine the followers scenario (Figure 1) The country in question, Country X, say Honduras, imports harvest-festival Q from country M (United States) at monetary value Pw+t, which includes an ad valorem tax and is the kindred value offered by othe r nations in the valet, including country E (El Salvador). At this footing, Honduras imports 20 units and consumes 60. The be 40 units are trade from the US. This is illustrated by the Honduran supply and read lines in Figure 1 and the suddenly elastic supply crimp with free trade of El Salvador. It is understood that a change in Honduran imports of product Q cannot affect the humankind bell of product Q.Figure 1. Trade CreationIf Honduras signed an RTA with El Salvador and the price of product Q from ElSalvador dropped to PE, Honduras would now produce 10 units of product Q, consume 70, and import the difference of 60 units. Because El Salvador now offers a lower price for product Q, Honduras now imports this product from El Salvador and not from the US.The consumer surplus gains of this RTA are tinct by nations a+b+c+d. The redness in producer surplus is indicated by expanse a. The loss of tariff revenue for Honduras is area c. Therefore the net welfare increase of t his RTA between El Salvador and Honduras is indicated by triangles b and d.Triangle b represents the amount of toil that was shifted from less efficient producers in Honduras to more efficient producers in El Salvador a better allocation of resources. Triangle d represents the increase in consumption of product Q.2.1.2 Trade DiversionTrade Diversion is illustrated in figure 2. once again the supply and get hold of lines are those of Honduras for product Q. Line S1 and S2 are the utterly elastic supply winds of USA and El Salvador respectively, and lines S1+t and S2+t are the tax inclusive supply curves of the very(prenominal) two countries.Figure 2. Trade DiversionHonduras imports product Q from the US at tax inclusive price Pw+t. El Salvador offers product Q at price PE+t and thus does not benefit from Honduran purchases.At price Pw+t Honduras produces 20 units, consumes 60, and imports 40 from the US. If Honduras and El Salvador now form an RTA and do not include the US, ta riffs volition be removed on imports from El Salvador but not from imports from the US. by and by forming the RTA Honduras would produce 10 million units, consume 80 million and import 60 million units of product Q from El Salvador at price PE.The RTA has turn trade from more efficient producers in the US to less efficient producers in El Salvador, so there is a declivity in the allocation of resources. On the other hand 10 million units are now import from El Salvador instead of being produced at property in Honduras. At the alike time 40 million units that were antecedently imported from the US are now being imported from El Salvador.The welfare loss from trade diversion is reflected rectangle f. The 40 million units that were imported from more efficient producers in the US whose free trade price is $1.00 are now imported from El Salvador at $2.00. The welfare loss is $40 million.The welfare gain from the customs union is calculated as the areas of triangles b and d. Triang le b is the welfare gain in the production side $5 million. Triangle d is the welfare gain in the consumption side $10 million.The total impact on welfare as a result of the RTA is minded(p) by the sum of the areas of triangles b and d deduction the area of rectangle f (b+d-f) welfare gain electronegative welfare loss. In this case the RTA generated a welfare loss of $25 million.Figure 2 illustrates that the idea of trade creation and trade diversion can be misleading. If, for example, the sum of areas of triangles b and d would be great than the area of rectangle f, the RTA would cause a net welfare gain. In this scenario, although trade has been divert from more efficient producers in one country to less efficient producers in another, the RTA increased welfare for the RTA sign language country.2.1.3 Gross Trade CreationFollowing the lead of Jacob Viner, Balassa (1967) evaluated the effects of the European Common Market with reference to its trade creating and trade diverting effect using Tinbergen (1962) and Pyhnen (1963) model -the gravity model. In his work he developed model that captured substitution of less efficient domestic and foreign suppliers for more efficient foreign suppliers gross trade creation which is different than Viners definition of trade creation according to which trade is created only at the expense of topical anaesthetic anesthetic anaesthetic producers.To illustrate the difference gross trade creation and trade creation proper as defined by Viner (1950), consider three avocation partners of one particular product countries A, B, and C, product Q (See Figure 3). Before sign language a RTA with country B, Country A imports product Q from both, Country B and Country C in equal amounts and has 4 local producers of the same(p) product (Figure 3a).In the case of trade creation proper (Figure 3b), by and by(prenominal) subscribe a RTA with country B, Country A continues to import equal amounts of product Q from countries B a nd C but has reduced the number of local producers of the same product. More efficient producers in Country B devour absorbed market share from local producers in Country A trade creation proper.Gross trade creation on the other hand (Figure 3c), considers that trade is created not only when local producers are substituted, but also when producers in third countries are substituted. In this case, after signing a RTA with country B, Country A decreases its imports of product Q from Country C and increases imports of the same product from Country B while keeping the same number of local producers. It is important to note that gross trade creation assumes that substituted producers in Country C were less efficient than producers in country B the contrary would constitute trade diversion.Figure 3. Trade Creation Proper vrs Gross Trade CreationLike in Cernat (2001), this paper evaluates the gross trade creating effects of the assessed RTAs.In his paper, Balassa (1967) provides evidence of trade creation in the European Common Market during six years since the Markets establishment. again, trade creation applies to the substitution of any less efficient producer for a more efficient one, in babelike of the producers base country. The why of the expected differences between the results of developed country RTAs and SS RTAs is explained in the next section.2.2 verifiable Evidence from SS RTAsA number of studies fork up been conducted to assess the effects of SS RTAs in partner countries -most of them undertake to determine if the RTAs were trade creating or trade diverting e.g. Evans (1998), Lewis et al. (1999), Flores (1997), Cernat (2001), Subramanian and Tamirisa (2001), Cernat (2003), Mayda and Steinberg (2006). Different methods take a crap been used and the results are mixed. This paper uses methods analogous to Cernat (2001) and Cheng paries (2003).In his paper, Cernat(2001) used the log-linear form of the gravity equation to asses nine SS RTAs. He f inds evidence that suggests that SS RTAs are less trade diverting than theoretically predicted. Cernats(2001) findings suggest that Mercosur and the Andean Community were overall, trade diverting.Mayda and Steinberg(2006) use a difference-in-difference estimation strategy at good level to assess the impact of COMESA on Ugandan imports. They present evidence that South-South trade agreements create positive but little economic gains, with changes in trade patterns, for their members (Mayda and Steinberg, 2003). This is different from Cernats(2001) results, which indicate that imports into COMESA members from third countries were on bonny 30 per cent higher than those predicted without the trade diversion the skinny variable. Mayda and Steinberg (2006) find evidence that no trade diversion takes place in COMESA.The mixed results from these studies, the increasing number of SS RTAs underway and the high number of countries wanting to total completely or in part in these RTAs poses the spare-time activity(a) questions why do policy makers from these countries advocate in favor of these RTAs? Should these RTAs be prosecute?, and the still not categorically answered question Are South-South regional Trade Agreements trade creating or trade diverting? Using the gravity model, this paper aims to get evidence from SS RTAs from the Americas.Theoretical Framework and Research Methodology***Intro***Problem DefinitionResearch ObjectiveResearch Questions3.1 Theoretical Framework3.1.1 Multiple Regression Analysis and Model createFigure 4. Regression HyperplaneMultiple regression analysis is a method of inferential statistics that beats the kindred between two or more independent variables and one dependent variable. The multiple regression model is given byWherey = dependent variable= regression constant of the population= regression coefficient for each variable xj=1,2,kk = number of independent variables= error of the modelDifferent from a simple regression equa tion -which forms a straight line in a two-dimensional space to represent the linear affinity between two variables the multiple regression model forms a hyperplane in a multidimensional space (Figure 4). This hyperplane represents the relationship between the dependent variable and k independent variables.To build a multiple regression model, that is, to construct a mathematical equation that represents the relationship between independent and dependent variables, a researcher must decideThe question that wishings to be answeredThe potential drop independent variablesWhat is a representative sample of the population should be at least four times the number of independent variables (Groebner, et al, 2008)The model used in this paper is well known and widely used by amicable scientists to survey the flow of various types of variables. This model is explained in section 3.1.3.3.1.2 Regression Model DiagnosisTo ensure the significance of an OLS regression analysis results, the following evaluation criteria are usually used (Groebner, et al, 2008)The coefficient of determination (R2 and R2 adjusted) mingying of the overall model (F-test) logical implication of individual variables (t-tests)Size of the standard variance of the modelMulticollinearity of variablesThe coefficient of determination rounds the proportion of variation in the dependent variable that can be explained with the independent variables used by the model. The value of R2 may range from 0-1, with 1 representing a perfect linear relationship between dependent and independent variables. Higher values of R2 are preferred as they would indicate that the chosen independent variables explain better the variations in the dependent variables.A derivate indicator, called adjusted R2, takes into account the number of independent variables in the model, and their part the variations in the dependent variable. Because R2 increases when independent variables are added to the model, even if the new variables move over no relationship with the dependent variable, adjusted R2 evaluates the model more precisely.The mansion houseificance of the overall model can be refractory by equivalence the signification F value given in the regression takings of a statistical software application, and the critical value for a given alpha level.The critical value for a given alpha level is driven using t-tables and statistical procedures explained in Groebner (2008).The entailment of individual variables is determined by comparability their calculated t-values with the critical t-value of the model. If their calculated t-values are greater than their critical t-values the variable is considered significant. To determine the critical t-values of independent variables, degrees of freedom guide to be calculated and interpolated with the desired level of significance in a t-table. For detailed explanations see Groebner (2008).The size of the standard release of the model measures the sp rinkling of observed values of the dependent variable, and the predicted values for the same variable. It is up to the researcher to determine an acceptable range for the standard error estimation.Multicollinearity occurs when two variables provide overlapping information to explain the variation in the dependent variable. To measure multicollinearity the researcher can use the VIF as an indicator. Generally, if the VIF 3.1.3 The Gravity Model of TradeFollowing Isaac Newtons principle of gravity, according to which two bodies will attract each other more when their sizes are increased and the distance between them is reduce the gravity model explains trade flow between two countries ground on the size of their economies and the distance between their economic centers.The equation histrionics of the gravity model of trade is(Formula 1)Where Fg represents trade flow, G is the constant, m1 and m2 are the economic dimensions of the two countries in question, and d is the distance bet ween the two countries. In its basic log-linear form, the gravity equation is as follows(Formula2)Where is the bilateral trade flow between countries i and j at time t, is the constant, is the immanent logarithm of the GDP of country i, is the inhering logarithm of the GDP of country j, is the natural logarithm of the distance between country i and country j, and is the normally distributed error.This basic gravity model is usually augmented by including other variables like contiguousness, common language, colonial links, common currency, and RTA membership among others. Different authors have suggested many different specifications for the gravity model of trade1, however there is no consensus about which model specification is more accurate and serves ruff in assessing RTAs. Moreover other authors have suggested that the gravity model is colored due to endogeneity and reverse causality (Magee, 2003) and have led others to use tout ensemble different methods to asses RTAs (Mayda Steinberg (2006).This paper uses a gravity model specification that is alike to Cernat (2001) but considers Cheng fence ins (2003) suggestions of eliminating dummy variables that might capture unintended trade distorting variables.To assess trade creation and trade diversion in nine RTAs, Cernat(2001) adds two dummy variables to an already augmented specification of the model Intra_RTA and Extra_RTA. The Intra_RTA dummy becomes a 1 when both, the trade and the exporting countries, are partners in the RTA being assessed by the two dummies. The Extra_RTA dummy becomes one when the trade country is part of the assessed RTA but the exporter is a third country.The model uses bilateral trade flows as a dependent variable and 18 independent variables GDP of importing country, GDP of the exporting country, GDP per capita of the importing country, GDP per capita of the exporting country, Population of the importing country, population of the exporting country, distance between t he capital cities of both countries, an contiguity dummy variable, a common language dummy variable, nine Intra_RTA dummy variables (one for each RTA assessed), and nine Extra_RTA dummy variables (one for each RTA assessed). wholly non-dummy variables expressed in their logarithmic form.In theory, the Intra_RTA dummies will capture the effect that the assessed RTA had on trade between partners of the RTA and the Extra_RTA dummy captures the effect of the same RTA on trade of RTA members with third countries.To diagnose a RTA as trade crating or trade diverting, Cernat (2001) knowing an Intra-Extra coefficient table (Table in this paper). According to this table, if a trade agreement increased trade between its partners at the expense of third countries -diverted trade, the Intra_RTA dummy should be positive and the Extra_RTA dummy negative. If the agreement created trade instead, the coefficients of both dummies would be positive.CoefficientExtra_RTAIntra_RTA consecrate++Trade cr eation and trade expansionTrade diversionTrade expansionTrade contractionTable 1 Dummy changeable InterpretationCheng Wall (2003) use a fixed-effect panel data analysis to measure the effect on trade of RTAs over time. Their proposed model allegedly controls the heterogeneity bias in the gravity model of trade. In it, Cheng Wall (2003) drop all dummy variables and even drop the distance variable. They argue that these variables bias the gravity model and they motivate their argument in a number of ways. First, they reason that economic distances are too hard to measure with accuracy because big countries have many economic centers, that are thousands of miles asunder(predicate) and that serve as trade centers for diffeEffect on Trade Flows of Regional Trade AgreementsEffect on Trade Flows of Regional Trade AgreementsAbstractThis paper studies the effect on trade flows of RTAs signed between development economies.

IntroductionBackgroundFour hundred and sixty two RTAs have been notified to the WTO up to February 2010 (WTO,2010). From 1948-1994 the GATT received one hundred and cardinal four notifications of RTAs, and since its creation in 1995, the WTO has received over 300 RTA notifications, (WTO,2010). This snub of forming trading blocs is likely to become stronger as more RTAs are soon under negotiation.Of particular interest to economists, and the focus of this paper, are South-South RTAs, that is, RTAs signed between countries of low income levels. There are reasons to believe that SS RTAs may not only fail to stimulate economic growth among member countries, but also hinder growth for these countries.In their book Regional Integration and Development, Winters and Schiffer (2003) differentiate that there is some evidence that North-South RTAs stimulate economic growth in the southern partner, little evidence that North-North RTAs stimulate growth and NO evidence that South-South RTAs do so. Specifically they argue that SS RTAs do not provide partners with entranceway to technology or knowledge that is characteristic of rich countries SS RTAs are unlikely to add credibility to government policies and may even hinder investment funds if not accompanied by liberalization of trade with the rest of the world and, SS RTAs are likely to generate only trade diversion and no trade creationMayda and Steinberg (2006) argue that SS RTAs are unlikely to provide the positive effects of competition and economies of scale because partner countries are both pocket-sized and poor. In a ddition, the loss of fiscal revenues harms the member country economies and finally, SS RTAs are more likely to divert trade rather than create trade. Willmore (1976) and Nicholls (1998) make identical points using the Central American Common Market as an example.Trade creation and trade diversion are concepts that were introduced by Jacob Viner in 1950. two terms refer to the redirection of trade flows as a consequence of an RTA. In trade creation, goods that were previously produced by a local economy are instead imported from more efficient producers in countries within the RTA. Trade diversion refers to the redirecting of trade from the more efficient producer to a less efficient producer within the RTA. In both cases, trade creation and trade diversion, the trade flows are affected by the reduction of tariffs to member countries typical of RTAs. Trade creation and trade diversion are explained with more detail in section 2.1 of this paper.A number of studies have been conduct ed to assess the effects of SS RTAs in partner countries -most of them attempt to determine if the RTAs were trade creating or trade diverting e.g. Evans (1998), Lewis et al. (1999), Flores (1997), Cernat (2001,2003)), Subramanian and Tamirisa (2001), Mayda and Steinberg (2006). Different methods have been used and the results are mixed. As a reference, this paper focuses on the results of Cernat (2001, 2003), Flores (1997), and Mayda and Steinberg (2006). Different methods were used in these studies and the results were mixed.Cernat (2001) used the log-linear form of the gravity equation to assess nine SS RTAs. He finds evidence that suggests that SS RTAs are less trade diverting than theoretically predicted. Cernat (2001) findings suggest that Mercosur and the Andean Community were overall, trade diverting. On the other hand Flores (1997), using a CGE analysis, concluded that Mercosur was trade creating.Mayda and Steinberg (2006) use a difference-in-difference estimation strategy at goodness level to assess the impact of COMESA on Ugandan imports. They present evidence that South-South trade agreements create positive but little economic gains, through changes in trade patterns, for their members. This is different from Cernat (2001) results, which indicate that imports into COMESA members from third countries were on average 30 per cent higher than those predicted without the trade diversion dummy variable. Mayda and Steinberg (2006) find evidence that no trade diversion takes place in COMESA.The mixed results from these studies, the increasing number of SS RTAs underway and the high number of countries wanting to join completely or in part in these RTAs poses the following questions Why do policy makers from these countries advocate in favor of these RTAs? Should these RTAs be pursued?, and the still not categorically answered question Are South-South Regional Trade Agreements trade creating or trade diverting? Using the gravity model, this paper aims to get evidence from SS RTAs from the Americas.1.2 Problem definitionDo South-South Regional Trade Agreements create trade or divert trade? The literature on this topic is vast and contradictory. Everybody thinks that SS-RTAs are trade diverting. Some papers present evidence of this. Other present evidence that they are actually trade creating. Finally others find evidence of very little trade creation and no significant evidence of trade diversion.With so many RTAS in place and many others underway, it is important to understand the effects of creating these trade blocs.Should poor countries pursue RTAs with poor countries? Are SS RTAs building blocks or stumbling stones towards the world liberalization of trade?1.3 Research ObjectiveThe main objective of this paper is to determine if MERCOSUR, Andean Community, and SICA were trade creating or trade diverting in the years 1995, 1998, 1999, 2003, 2007.1.3.1 Major research questionIs there significant evidence of trade creation or tra de diversion on the years 1995,1998,1999,2003,2007 for Mercosur, Andean Community and SICA?1.3.2 Minor research questionIs there significant evidence that suggests that RTA members of the above mentioned RTAs increased trade between them and their partners?Is there significant evidence that suggests that members of the above mentioned RTAs increased trade between them and third countries?Is there significant evidence that suggests that the increase in trade between RTA partners of the above mentioned RTAs is higher than the decrease in trade between RTA members and third countries?1.4 Theoretical Framework1.4.1 The Gravity model of tradeThe gravity model uses Newtonian gravity principles to study human behavior. It is widely used by economists and social scientists to predict flows of trade, people, goods, money, and other variables as an effect of changes in economic policies, fiscal policies, new laws, bans and other distortions to the flow of a given variable.The original gravity model of trade assumes that two countries will trade more or less depending on the sizes of their economies and the distance between their economic centers. It was created independently by Tinbergen (1962) and Pyhnen (1963) and augmented in later years to include other independent variables that may cause a change in trade flows. These augmented versions of the basic gravity model may include population of the two countries, presence of common borders, same language, common colonizer, and others that the researcher regards as relevant.The gravity model specifications used in this paper are similar to those of Cernat(2001) and Cheng Hall (2003). These specifications are used to run OLS regressions on trade data of 1995, 1998, 1998, 2003 and 2007. One set of pooled data including the years mentioned is analyzed using the same gravity specifications.The results of these regressions provide evidence of gross trade creation and diversion as specified by Balassa (1967)1.4.2 Research Met hodology and DesignThe paper uses standard OLS analysis, with bilateral imports as a dependent variable and 17 independent variables GDP of the importing country, GDP of the exporting country, Population of the importing country and population of the exporting country, distance between the capital cities of each country pair, Intra_x dummy variable for each RTA, Extra_x dummy variable for each RTA. The values of GDPs, distance and populations are used in their logarithmic form.GDPs and population data was collected from the WB databank. Trade data was collected from UNCTADs database using the WB banks WITS application.1.4.3 Research AssumptionsCosts of transportation are relative to the great circle distance between economic centers of countries studiedAll countries have one economic center, namely their capital cities.The error coefficient of the log-linear gravity model used in this paper is normally distributed with a mean of zero and constant variance for all observations. It i s also assumed that error pairs are uncorrelated.GDPs, population, and trade data collected belongs to the population1.4.4 Research Limitations1.5 thesis StructureThe remainder of this paper is organized as follows Chapter 2 presents a literature review that explains trade creation and trade diversion, the effect of both and findings of previous papers that assess RTAs. Chapter 3 explains the gravity model used on the paper, how data was collected and organized, and the considerations in analyzing data. Chapter 4 summarizes the findings and Chapter 5 concludes.2. Literature ReviewThere is extensive literature on RTAs. This literature either predicts the effects of a RTAs using a computable-general equilibrium analysis or they measure the effects of an FTA using aggregate data or commodity level data.The concern of most authors, and the reason why they conduct their research, is that FTAs and specially SS FTAs may divert trade rather than create it. In the former case, purchases fro m an efficient producing country are replaced by purchases of a less efficient FTA partner.This section serves three purposes 1. It explains trade creation and trade diversion to the reader so she can better understand the methodology used to assess the selected RTAs. 2. It presents the reader with the results of previous findings so that the reader can compare the results of this paper with previous results of other authors. 3. It gross trade creation and diversion so that the reader can understand the results of the research.2.1 Trade Creation and Trade DiversionTrade creation and trade diversion as defined by Viner (1950), refer to changes in flow of trade between nations. Trade creation happens when trade is switched from less efficient producers of one country to more efficient producers in another country a better allocation of resources. In trade diversion trade is shifted from more efficient producers in one country to less efficient producers in another country -a worsenin g in the allocation of resources.2.1.1 Trade CreationTrade creation can be defined as the net welfare gain that results from the grounding of an RTA, both on the production and on the consumption side. Some economists though, think that it is more precise to think of trade creation only as the increase in welfare from the production side (Senior-Nello S, 2010). In this paper the former definition of welfare is considered.To understand trade creation, imagine the following scenario (Figure 1) The country in question, Country X, say Honduras, imports product Q from country M (United States) at price Pw+t, which includes an ad valorem tax and is the same price offered by other nations in the world, including country E (El Salvador). At this price, Honduras imports 20 units and consumes 60. The stay 40 units are imported from the US. This is illustrated by the Honduran supply and demand lines in Figure 1 and the perfectly elastic supply curve with free trade of El Salvador. It is under stood that a change in Honduran imports of product Q cannot affect the world price of product Q.Figure 1. Trade CreationIf Honduras signed an RTA with El Salvador and the price of product Q from ElSalvador dropped to PE, Honduras would now produce 10 units of product Q, consume 70, and import the difference of 60 units. Because El Salvador now offers a lower price for product Q, Honduras now imports this product from El Salvador and not from the US.The consumer surplus gains of this RTA are correspond by areas a+b+c+d. The loss in producer surplus is indicated by area a. The loss of tariff revenue for Honduras is area c. Therefore the net welfare increase of this RTA between El Salvador and Honduras is indicated by triangles b and d.Triangle b represents the amount of production that was shifted from less efficient producers in Honduras to more efficient producers in El Salvador a better allocation of resources. Triangle d represents the increase in consumption of product Q.2.1.2 Trade DiversionTrade Diversion is illustrated in figure 2. Again the supply and demand lines are those of Honduras for product Q. Line S1 and S2 are the perfectly elastic supply curves of USA and El Salvador respectively, and lines S1+t and S2+t are the tax inclusive supply curves of the same two countries.Figure 2. Trade DiversionHonduras imports product Q from the US at tax inclusive price Pw+t. El Salvador offers product Q at price PE+t and thus does not benefit from Honduran purchases.At price Pw+t Honduras produces 20 units, consumes 60, and imports 40 from the US. If Honduras and El Salvador now form an RTA and do not include the US, tariffs will be removed on imports from El Salvador but not from imports from the US. subsequently forming the RTA Honduras would produce 10 million units, consume 80 million and import 60 million units of product Q from El Salvador at price PE.The RTA has diverted trade from more efficient producers in the US to less efficient producers in El Sa lvador, so there is a worsening in the allocation of resources. On the other hand 10 million units are now imported from El Salvador instead of being produced at dwelling house in Honduras. At the same time 40 million units that were previously imported from the US are now being imported from El Salvador.The welfare loss from trade diversion is reflected rectangle f. The 40 million units that were imported from more efficient producers in the US whose free trade price is $1.00 are now imported from El Salvador at $2.00. The welfare loss is $40 million.The welfare gain from the customs union is calculated as the areas of triangles b and d. Triangle b is the welfare gain in the production side $5 million. Triangle d is the welfare gain in the consumption side $10 million.The total impact on welfare as a result of the RTA is given by the sum of the areas of triangles b and d minus the area of rectangle f (b+d-f) welfare gain minus welfare loss. In this case the RTA generated a welfare loss of $25 million.Figure 2 illustrates that the idea of trade creation and trade diversion can be misleading. If, for example, the sum of areas of triangles b and d would be greater than the area of rectangle f, the RTA would cause a net welfare gain. In this scenario, although trade has been diverted from more efficient producers in one country to less efficient producers in another, the RTA increased welfare for the RTA signing country.2.1.3 Gross Trade CreationFollowing the lead of Jacob Viner, Balassa (1967) evaluated the effects of the European Common Market with reference to its trade creating and trade diverting effect using Tinbergen (1962) and Pyhnen (1963) model -the gravity model. In his work he developed model that captured substitution of less efficient domestic and foreign suppliers for more efficient foreign suppliers gross trade creation which is different than Viners definition of trade creation according to which trade is created only at the expense of local pr oducers.To illustrate the difference gross trade creation and trade creation proper as defined by Viner (1950), consider three trading partners of one particular product countries A, B, and C, product Q (See Figure 3). Before signing a RTA with country B, Country A imports product Q from both, Country B and Country C in equal amounts and has 4 local producers of the same product (Figure 3a).In the case of trade creation proper (Figure 3b), after signing a RTA with country B, Country A continues to import equal amounts of product Q from countries B and C but has reduced the number of local producers of the same product. More efficient producers in Country B have absorbed market share from local producers in Country A trade creation proper.Gross trade creation on the other hand (Figure 3c), considers that trade is created not only when local producers are substituted, but also when producers in third countries are substituted. In this case, after signing a RTA with country B, Countr y A decreases its imports of product Q from Country C and increases imports of the same product from Country B while keeping the same number of local producers. It is important to note that gross trade creation assumes that substituted producers in Country C were less efficient than producers in country B the contrary would constitute trade diversion.Figure 3. Trade Creation Proper vrs Gross Trade CreationLike in Cernat (2001), this paper evaluates the gross trade creating effects of the assessed RTAs.In his paper, Balassa (1967) provides evidence of trade creation in the European Common Market during six years since the Markets establishment. Again, trade creation applies to the substitution of any less efficient producer for a more efficient one, independent of the producers base country. The why of the expected differences between the results of developed country RTAs and SS RTAs is explained in the next section.2.2 Empirical Evidence from SS RTAsA number of studies have been con ducted to assess the effects of SS RTAs in partner countries -most of them attempt to determine if the RTAs were trade creating or trade diverting e.g. Evans (1998), Lewis et al. (1999), Flores (1997), Cernat (2001), Subramanian and Tamirisa (2001), Cernat (2003), Mayda and Steinberg (2006). Different methods have been used and the results are mixed. This paper uses methods similar to Cernat (2001) and Cheng Wall (2003).In his paper, Cernat(2001) used the log-linear form of the gravity equation to asses nine SS RTAs. He finds evidence that suggests that SS RTAs are less trade diverting than theoretically predicted. Cernats(2001) findings suggest that Mercosur and the Andean Community were overall, trade diverting.Mayda and Steinberg(2006) use a difference-in-difference estimation strategy at commodity level to assess the impact of COMESA on Ugandan imports. They present evidence that South-South trade agreements create positive but little economic gains, through changes in trade p atterns, for their members (Mayda and Steinberg, 2003). This is different from Cernats(2001) results, which indicate that imports into COMESA members from third countries were on average 30 per cent higher than those predicted without the trade diversion dummy variable. Mayda and Steinberg (2006) find evidence that no trade diversion takes place in COMESA.The mixed results from these studies, the increasing number of SS RTAs underway and the high number of countries wanting to join completely or in part in these RTAs poses the following questions Why do policy makers from these countries advocate in favor of these RTAs? Should these RTAs be pursued?, and the still not categorically answered question Are South-South Regional Trade Agreements trade creating or trade diverting? Using the gravity model, this paper aims to get evidence from SS RTAs from the Americas.Theoretical Framework and Research Methodology***Intro***Problem DefinitionResearch ObjectiveResearch Questions3.1 Theoreti cal Framework3.1.1 Multiple Regression Analysis and Model BuildingFigure 4. Regression HyperplaneMultiple regression analysis is a method of inferential statistics that measures the relationship between two or more independent variables and one dependent variable. The multiple regression model is given byWherey = dependent variable= regression constant of the population= regression coefficient for each variable xj=1,2,kk = number of independent variables= error of the modelDifferent from a simple regression equation -which forms a straight line in a two-dimensional space to represent the linear relationship between two variables the multiple regression model forms a hyperplane in a multidimensional space (Figure 4). This hyperplane represents the relationship between the dependent variable and k independent variables.To build a multiple regression model, that is, to construct a mathematical equation that represents the relationship between independent and dependent variables, a res earcher must decideThe question that needs to be answeredThe potential independent variablesWhat is a representative sample of the population should be at least four times the number of independent variables (Groebner, et al, 2008)The model used in this paper is well known and widely used by social scientists to measure the flow of various types of variables. This model is explained in section 3.1.3.3.1.2 Regression Model DiagnosisTo ensure the significance of an OLS regression analysis results, the following evaluation criteria are usually used (Groebner, et al, 2008)The coefficient of determination (R2 and R2 adjusted)Significance of the overall model (F-test)Significance of individual variables (t-tests)Size of the standard deviation of the modelMulticollinearity of variablesThe coefficient of determination measures the proportion of variation in the dependent variable that can be explained with the independent variables used by the model. The value of R2 may range from 0-1, wit h 1 representing a perfect linear relationship between dependent and independent variables. Higher values of R2 are preferred as they would indicate that the chosen independent variables explain better the variations in the dependent variables.A derivate indicator, called adjusted R2, takes into account the number of independent variables in the model, and their ploughshare the variations in the dependent variable. Because R2 increases when independent variables are added to the model, even if the new variables have no relationship with the dependent variable, adjusted R2 evaluates the model more precisely.The Significance of the overall model can be determined by comparing the Significance F value given in the regression create of a statistical software application, and the critical value for a given alpha level.The critical value for a given alpha level is determined using t-tables and statistical procedures explained in Groebner (2008).The Significance of individual variables i s determined by comparing their calculated t-values with the critical t-value of the model. If their calculated t-values are greater than their critical t-values the variable is considered significant. To determine the critical t-values of independent variables, degrees of freedom need to be calculated and interpolated with the desired level of significance in a t-table. For detailed explanations see Groebner (2008).The size of the standard deviation of the model measures the dispersion of observed values of the dependent variable, and the predicted values for the same variable. It is up to the researcher to determine an acceptable range for the standard error estimation.Multicollinearity occurs when two variables provide overlapping information to explain the variation in the dependent variable. To measure multicollinearity the researcher can use the VIF as an indicator. Generally, if the VIF 3.1.3 The Gravity Model of TradeFollowing Isaac Newtons principle of gravity, according t o which two bodies will attract each other more when their sizes are increased and the distance between them is cut the gravity model explains trade flow between two countries establish on the size of their economies and the distance between their economic centers.The equation design of the gravity model of trade is(Formula 1)Where Fg represents trade flow, G is the constant, m1 and m2 are the economic dimensions of the two countries in question, and d is the distance between the two countries. In its basic log-linear form, the gravity equation is as follows(Formula2)Where is the bilateral trade flow between countries i and j at time t, is the constant, is the natural logarithm of the GDP of country i, is the natural logarithm of the GDP of country j, is the natural logarithm of the distance between country i and country j, and is the normally distributed error.This basic gravity model is usually augmented by including other variables like adjacency, common language, colonial li nks, common currency, and RTA membership among others. Different authors have suggested many different specifications for the gravity model of trade1, however there is no consensus about which model specification is more accurate and serves beaver in assessing RTAs. Moreover other authors have suggested that the gravity model is dyed due to endogeneity and reverse causality (Magee, 2003) and have led others to use unaccompanied different methods to asses RTAs (Mayda Steinberg (2006).This paper uses a gravity model specification that is similar to Cernat (2001) but considers Cheng Walls (2003) suggestions of eliminating dummy variables that might capture unintended trade distorting variables.To assess trade creation and trade diversion in nine RTAs, Cernat(2001) adds two dummy variables to an already augmented specification of the model Intra_RTA and Extra_RTA. The Intra_RTA dummy becomes a 1 when both, the importing and the exporting countries, are partners in the RTA being ass essed by the two dummies. The Extra_RTA dummy becomes one when the importing country is part of the assessed RTA but the exporter is a third country.The model uses bilateral trade flows as a dependent variable and 18 independent variables GDP of importing country, GDP of the exporting country, GDP per capita of the importing country, GDP per capita of the exporting country, Population of the importing country, population of the exporting country, distance between the capital cities of both countries, an adjacency dummy variable, a common language dummy variable, nine Intra_RTA dummy variables (one for each RTA assessed), and nine Extra_RTA dummy variables (one for each RTA assessed). All non-dummy variables expressed in their logarithmic form.In theory, the Intra_RTA dummies will capture the effect that the assessed RTA had on trade between partners of the RTA and the Extra_RTA dummy captures the effect of the same RTA on trade of RTA members with third countries.To diagnose a RTA a s trade crating or trade diverting, Cernat (2001) knowing an Intra-Extra coefficient table (Table in this paper). According to this table, if a trade agreement increased trade between its partners at the expense of third countries -diverted trade, the Intra_RTA dummy should be positive and the Extra_RTA dummy negative. If the agreement created trade instead, the coefficients of both dummies would be positive.CoefficientExtra_RTAIntra_RTASign++Trade creation and trade expansionTrade diversionTrade expansionTrade contractionTable 1 Dummy Variable InterpretationCheng Wall (2003) use a fixed-effect panel data analysis to measure the effect on trade of RTAs over time. Their proposed model allegedly controls the heterogeneity bias in the gravity model of trade. In it, Cheng Wall (2003) drop all dummy variables and even drop the distance variable. They argue that these variables bias the gravity model and they motivate their argument in a number of ways. First, they reason that economic distances are too hard to measure with accuracy because big countries have many economic centers, that are thousands of miles apart and that serve as trade centers for diffe

Emergence of Ubiquitous Computing in Advertising

Emergence of omni bear reason in publiciseE preciseday Interactions with advertizing Entertainment in the Emergence of Ubiquitous ComputingAbstractTechnology has been advancing rapidly and although the advances of the past fifty years occupy not benefited everyone equ on the wholey, the path in which humanitys live give away their lives and the functioning of societies has been immensely changed as a egress of these advances. Ubiquitous or pervasive computer science refers to the overbold wave of applied science which is the result of advances in selective deposeation and communications technologies which al offset do it execut satisfactory to seamless constitute size adequate to(p) cipher catchs into objects, locations and notwithstanding people. Embedded gizmos now shift human attention from systems to their fields as they work tirelessly to reduce the cognitive tear and perceive how humans grass be assisted in per building tasks associated with whatev er aspects of their existence. The physical and the digital earthly concerns atomic number 18 now comfortably related and every object in the solid macrocosm git now imbibe a repre directation in the digital mankind. The efficiency of omnipresent twists to be place setting sensitive and fact aw be has changed the appearance in which humans interact with much(prenominal) devices, offering rich raw possibilities for operations to announce and pastime, which be amongst the oldest of human endeavours. This essay presents a discussion around publicizing and entertainment in the omnipresent get on and examines what changes be promising to emerge in the rising. Contents (Jump to)IntroductionThe Ubiquitous Environment publicize in the Ubiquitous yearsEntertainment in the Ubiquitous AgeConclusionBibliography/ReferencesIntroductionUbiquitous cypher, which is similarly referred to as pervasive computer science, is to the highest degree the notion that as a res ult of continuous advances in engineering, development engineering science, communications, integrated circuit chip technologies and sensors etc computer technology devices go forth generate sm on the wholeer, cheaper, much cap fit and bust adequate to(p) to weave themselves into the fabric of terrene life until they become indistinguishable from it (Schuster, 2007, Pp. 9 11). It was Mark Weiser, chief scientist of xerox copys Palo Alto query Centre, who first presented the concept of ubiquitous computing, the threesome wave in computing and predicted that technology go forthing recede into the accentuate of our lives as computers evolve into quite, invisible servants that go forth help people to sedately do each kinds of tasks in a manner that impart ob run them from becoming overloaded by interactions with computing (Wikipedia, 2007, Mark Weiser). Thus, computers leave alone amplify the human unconscious and enhance their ability to productively control, intera ct and mavin their surround. Un uniform the conventional computing concepts, which regard computers as devices that run programs in a realistic surround to accomplish a task, ubiquitous or pervasive computing philosophy considers computers as macrocosm devices that brook a capacity for interaction with a potential portal into an finishing selective selective in doion space that assists exploiters to perform tasks in an cultivation enhanced physical space, rather consequently as devices that execute softw atomic number 18 whose consummation must be controlled by a user. Obviously, the capacity of computing devices to act as portals into an application selective selective training space is wholly rendered realizable if the fabrication cost, performance capabilities and dependability of computing devices is enhanced as a result of advances in technology over a broad front (Hennessy, 2007, Chapter 1).Today, selective information processing, collecting and emitting de vices are to be found all around humans in all settings related to their existence, at kinfolk, office, in surfping malls or hospitals as easily as in transportation vehicles etc (Stakutis, 2005, Chapter 1). These computing devices bedevil been vastly miniaturised as compared to what was available in the past and they are now very often cartridge clips to a greater extent(prenominal)(prenominal)(prenominal) energy efficient, with enhanced capablities in terms of performance and connectivity with an separate(prenominal) devices as hearty as having a headmaster capacity for interfacing salubrious with smarter sensors. To a casual observer, the wide array of computing devices that are to be found all around us are barely noticeable and they are there to serve reliably, with let on imposing a cognitive load on humans, so that the quality of human existence in all environments flock be enhanced. Discrete radio tags, vigorous phones that halt a capacity for acting as gat e slipway for the World Wide Web and for connecting to more than other intelligent devices, intelligent debunks and maps that loafer be presented with information needs, chemical sensors, discrete radio sensors, scene cameras, intelligent assistive devices and gaming devices that provide entertainment or information are all testimony to the come alkali of the new age of ubiquitous computing. Artificial intelligence is now wide involved with all types of computing to enhance the quality of interactions in the midst of human users and a profit of intelligent computing devices, which collect and process data on a massive scale. Context, which refers to information that is assistive in gauging, or making calculatements closely an entity, which whitethorn be a person, place or object which is relevant for interaction between a user and an application is now able to be fed into a ubiquitous device which cigaret then react intelligently to fulfil the gather upments of its hu man users without placing any burdens on those that it has been designed to assist (Loke, 2007, Chapter 1). Location of people or objects, time, execution state of applications, user emotions, user intentions, the state of brain activity of users, computational resources that are available, the state of software applications and available network bandwidth are examples of scopes that disregard be of use to ubiquitous devices in interacting with users in a superior manner. Device designers drive out now be highly creative about development context information and as well in regard to what keep be feasibly sensed, the optimal manner in which information tolerate be sensed and how sensor information may be used to judge context to optimise device interactions and utility. A number of contextual cues that have been inferred by a ubiquitous device can be have to form an idea about a situation and the device can then be made to react in accordance with the requirements for a situ ation. The notion of situation get ats it practicable for the ubiquitous system designers to carve the world into manageable pieces that can be sensed by sensors, with a detachment of reaction rules for each manageable piece providing an adequate response for incompatible situations. Thus, a context aware ubiquitous system should be able to sense, think and act in a manner that is as assistive to humans as come-at-able (Loke, 2007, Chapter 2).If a sense of context and situation can be programmed into the capacity for intelligence of a ubiquitous device, then it should also be purloin to expect that norms or expectations of eliminate doings from device under given situations involving external contexts can also be incorporated into the programming for the device (Ibrahim, 2007, Pp. 54 58). Thus, ubiquitous devices should be able to sense a situation or a set of context in lay to try and interact in the approximately conquer manner with human users. As an example, locatio n and time context can be utilised to present the most appropriate advertize messages to shoppers on a supermarket publicise board and it may also be potential to incorporate an ability to qualify what items ought to be highlighted more, depending on the inventory line situation for a store, or the rate at which sales are existence made. Advertising companies are constantly wanting better ways to promote their goods and services to selected consumers who are achievable to be most open(a) to such messages and ubiquitous, or pervasive environments pass on permit give upy of the most relevant denote messages, which have been selected from a large number of possible messages to consumers in a far more ad hominem, intimate and appropriate manner then the mass media advertize that has been available (Leckenby, 2006, Advertising Issues) and (Hong, 2007, Advertising in the Environment). In the ubiquitous world it leave alone be possible to generate believable, individualise dity rich story characters on a uncover that may want to appropriately alter the emotional state of a human, depending on the time and their physical designer as sensed from their trunk posture (Li, 2006, Pp. 132). Emotion recognition systems may also take a shit it possible for entertainment systems to suggest the castigate movies, audio clips or interactive games and it may be possible to provide real time information on a wide concoction of issues to bus commuters or to generate melody which is god by the motion of a human conductor within the standard atmosphere (Li, 2006, Pp. 31, 132, 223, 229, 293, 366, 384 and 433). The possibilities for enhancing interactions related to advertizement and entertainment are many and ubiquitous devices in the main try to ease the cognitive load and provide intelligent signal detection of user needs.Entertainment and advertisement are amongst the oldest concepts that are known to piece (Vogel, 2007, Pp. 1 5). As a result of prod uctivity increases, which have also been assisted by advances in computing and information technology, leisure time has increased and people spend more time on all forms of leisure and entertainment activities. Although demand for entertainment has increased, so also has the mixed bag of entertainment which is available and individuals have the greatest preference for rich media video type viewing activities that are relatively affordable. Although, the advertising industry is doing well also, it has been hampered by strict regulations on what can and cannot be done, with expenditure switching from the traditional advertising mediums to the new electronic forms of advertising that use emerge technologies (Sweney, 2007, Paragraph 1) and (Ramsey, 2004, Pp. 1 2). Online advertising expenditure in the United States in the year 2004 alone exceeded $ 17.5 billion and the consumer is in control, wanting unique and hypnotic forms of advertising and entertainment. Thus, it makes sense t o try and understand how individuals pass on interact with advertising and entertainment in the new ubiquitous age and this essay presents a discussion about the in all likelihood form that advertising and entertainment depart take in the future.The Ubiquitous EnvironmentIt is appropriate at this coalition to try and imagine what the ubiquitous world of tomorrow is probably to be like. The world of the future give be characterised by wireless connectivity and miniature, just immense computing author that is connected to very fine sensors (Mathieson, 2005, Pp. 1 10). Global piping systems (GPS) allow make it possible for location sleuthing to within meters and it forget be possible to interact with intelligent computing devices development the most convenient human modes for interaction, idiom and hearing. Converged networks that connect ubiquitous devices allow be intelligent, high capacity and high speed networks with a capacity for moving huge amounts of data to a ny connection very rapidly. Short range wireless networks, similar to Bluetooth, go out supplement global connectivity provided by the ubiquitous network. The occurrence of selected events pass on be able to pioneer intelligent responses from devices and as an example it go forth be possible to inform the police and nominated relatives of an individuals location if air bags in a car were to be inflated as a result of an accident. It will be possible to monitor the activities of the children in a family in order to determine if a child has attended class or if they may have ventured too far away from a neighbourhood. electronic money contained in RFID tags which are attached to a car, or rambling devices that are carried by a person will be able to pay for any road toll, bridge taxes or minor handicraft violations without a requirement to stop. 3G cellular networks will become prolific and they will make it possible to have unified voice, video and data connections serve all human senses to provide rich interaction experiences. Computers will be able to create close to real life experiences for humans that seduce all their senses and already scientists are thinking about devices that will come alive the human sense of smell (Kaye, 2001, Pp. 1 20). Smart cloths will have a capacity for monitoring body signals and it will be possible to monitor brain waves to interact with computing devices. Intelligent home appliances will be able to monitor what is available in a home and they will not only alert individuals if the refrigerator is running low on certain items, exactly tiny smart dust sensors will also monitor food items for biological and chemical agents that determine if such items are still fit for human consumption. Intelligent homes, buildings and stores as well as hospitals will react to individual needs and provide appropriate assistance as required. Prompt and pre-emptive response from computing will have become a human existences. Sophisti cated avatar characters will provide more pleasing human computer interactions that will convey elements of emotion that has been generated by computers. Japans ubiquitous architecture provides an indication of many trends that are emerging for the future (Krikke, 2005, Pp. 4 9). Ubiquitous or pervasive computing is the result of advance networking, powerful private computing, instituteded computing and advanced artificial intelligence establish human computer interaction capability.The ubiquitous age is characterised by the evolution of ambient intelligent environments and these environments are determined by new interaction technology which provides for new ways of using content, new sensing or stimulus generating technologies, faster and more powerful computers and far greater storage capacities for data etc (Eyles, 2007, Pp. 4). The ubiquitous age will be characterised by ubiquitous computing, ubiquitous communication and intelligent user friendly interfaces and the resul ting ambient intelligence will provide for context awareness, personalisation, denseness and adaptability. Context awareness refers to a device having knowledge about its environment and acting in accordance with such knowledge, personalisation refers to having the ability to deliver information and interactions in accordance with a users requirements and adaptability refers to the device having a capacity for modifying its performance according to externally imposed requirements to best leave to a user.Clearly, many opportunities will exist for utilising new technology for advertising and entertainment. However, in view of the fact that the ubiquitous environment will have the capacity for collecting a large amount of personal data which will be used for enriching individual experiences, but which can also be misused, privacy in the ubiquitous environment is an issue (Mutanen, 2007, Pp. 24 43). A number of techniques are being researched to protect individual privacy in the ubi quitous age, but the trusted authority concept is amongst the more promising ways for protecting individual privacy.Advertising in the Ubiquitous AgeUbiquitous environments will permit a variety of methods to present advertising messages to people, including email, instant messaging, cell phone, network television and electronic ostentation boards etc that are linked together as a result of intersection point of new mobile technology, IT and media on an integrated global infrastructure (Ihlstr, 2007, Pp. 1 5). The ubiquitous environment will have a chain of sensors that will be deployed by advertising service providers to sense contexts, including location, weather condition variables, such as temperature and what the intended audience is engaged in at a location, so that the more appropriate advertising message on the right channel may be presented (Leckenby, 2007, Advertising Issues). The context information is useful for presenting the right advertising messages to the right people at the right time and on the right channel using the more appropriate form of advertising message. Context is also important for displaying advertising messages that are likely to be important for a particular location, such as those messages that are placed by local businesses in a suburb. Research indicates that although tastes are likely to vary, recipients are interested in the entertainment content of advertisements and this center that the right advertising messages have to be created for the right format. Advertising messages should provide for a means by which a recipient can follow up on what has been received and recipients will sure require that their privacy and security be protected. Consumers who are linked to the ubiquitous network of devices can be made to provide information about their preferences and it is likely that they may want to have their more relevant personal attributes made available on a ubiquitous user database. The ubiquitous environment is certain to have a large number of peripheral displays that are mounted at convenient locations, including close to elevators, at convenient points on streets and in shopping malls or other public locations. Serendipitous advertisements are most likely to fit in well on displays in a ubiquitous environment, because other messages can be sent in a more personalised and discrete manner. The advertisements that are required to be placed will be booked with advertising service providers who will have facilities for creation of advertising messages and the distribution of such messages over the ubiquitous networks.It is most likely that mobile wireless networks will become even more important in an age of ubiquitous networks and this means that personal mobile devices, e exceptionally a PDA type device or an advanced mobile phone which can be used for a wide variety of interactions with the ubiquitous network and other users will come upon a higher level of significance in the lives of i ndividual users (Loke, 2007, Chapter 3). Individuals will be using such devices to send and receive emails, transfer bullion to businesses or other users, retain data for a wide variety of purposes including inventory for groceries that are in stock at home, nimble purchase needs and any purchasing transactions that may have been carried out in the past etc. Sensors placed at various locations on the ubiquitous networks will be able to interrogate the mobile device of a user and depending on what information is permitted to be shared the advertising and entertainment service providers will be able to determine what is likely to be of interest to the owner of a mobile. Thus, those who are within an airport terminal may be provided with advertising related to bargain fares, magical spell a short message from a PDA can sour a message containing information about local restaurants offering special deals. Advertising displays may call individuals on a first stir basis subsequentl y having sensed information related to their identity from their personal mobile device when they are in proximity of an intelligent display and it will be possible for such individuals to interact with intelligent displays using speech to present their preferences (Mathieson, 2005, Pp. 1 10). It will be possible to shop for pizza, movies, books and music anywhere and at anytime, with the purchase instructions emanating from a personal device along with a payment authority and it will be possible to accept digital delivery in a format which is both highly portable and widely usable.Today we live in a world in which very many advertising messages influence individuals as they carry on with their daily lives and many of such advertising messages are likely to be of little interest. The rising cost of advertising makes advertising expensive. It is important that if individuals find something that interests them in the large number of advertising messages that they are presented with, then they should be able to quickly retrieve information for further interactions with the advertizer. Beaming is a new advertising technique that is being experimented with by several firms and the idea is to permit those who view advertising on electronic displays to retrieve and store electronic contact information into their mobile devices with their devices infrared or Bluetooth port (Krikke, 2005, Pp. 24). The information that is able to be transferred into a mobile device finished radiant is then used by the device to provide links through the network for further interactions with the advertisers. Newer forms of beaming will permit those mobile devices with a camera to photograph information that has been coded into black and symbols, called SpotCodes. A SpotCode has been presented in innovation 3, below. After a phone has succeeded in clicking in information that has been presented on a visual advertisement, it will be possible to use this information to retrieve all the details into an email that can be sent to a nominated address, or if desired, immediate purchase can be made by using the mobile device. Thus, emerging technologies will make it possible to enhance the effectiveness of advertising by making it cheaper, easier and more convenient to follow up on advertising, which should be of benefit to the advertiser and the consumer. The idea is to facilitate transactions and to enhance convenience in a manner that will not waste resources or the attention duet of the consumer. Great opportunities will exist to develop evolving proportionships with consumers through ubiquitous advertising and advertisers, or at least their messages, can go where the customer is, with a capacity for initial interest to be rapidly transformed into more information or interaction without any need to move through the physical space.Advertising message delivery does not have to be visual all the time and targeted audio technology will make it possible for laser beam s to be pointed to persons who will then be the only ones who will be able to hear an audio message (Krikke, 2005, Pp. 143 160). Thus, after sensing individual preferences, it will be possible to direct speech communications to individuals in a location so that only those who are likely to be interested listen to these messages. Thus, it is not just Bluetooth that will be used to transmit short range location based information. The ubiquitous network will follow the user and not the other way round. Augmented reality devices will have been made consummate in the ubiquitous age and those who live in this age will not just be carrying a PDA type device, but they will also be wearing a comfortable spectacle, if they so desire, that will assist in visual encounters with the ubiquitous world. It will be possible to superimpose additive information on to visual advertising messages that may be presented to individuals through the augmented reality devices and examples of such additiona l information may include balance of a bank estimate containing electronic money, or location information for outlets. It will even be possible to interact with large electronic advertising boards through gestures in order to prompt them to provide additional information to either a PDA type wireless device or the augmented reality device which may be worn by a user. Researchers have already tried to develop a gesture recognition expression that can change the way in which humans interact with ubiquitous computing devices of the future (Krikke, 2005, Pp. 202). Promotions and special offers can be quickly presented to consumers who can electronically collect coupons and if a loyal shopper is identified during an advertising or promotional campaign, they can be presented especially attractive discounts or offers electronically. see recognition and the detection of emotions by examining faces will make it possible to cling to up a loyal customer who may be spirit a bit down and t he buying habits of consumers can be examined to determine if certain consumers are loosing interest, so that a special effort can be mounted to win them back. It will be possible to embed identity on to each person using RFID devices that may be mounted on to a watch, or even be embed under a persons skin so that immediate identification and connection to the most appropriate databases that are likely to be of interest can be made possible. Very many possibilities for enhancing advertising present themselves, but the key to have these possibilities becoming reality is the advances that can be made in packing small chips with huge computing power and imbuing networks with capacity and speed.Entertainment in the Ubiquitous AgeAlthough better networks and more powerful computers as well as advances in technology on a broad front will enhance the boilersuit entertainment experience in the ubiquitous age, entertainment in the new era will be characterised by its extension into the phys ical world and a capacity for interaction (Eyles, 2007, Pp. 1 5). Augmented reality will have an impact on the entertainment experience by superimposing the virtual on to the real in a number of ways that may also include the use of holograms. Internet will add to the traditional methods for delivering entertainment content to viewers and video appliances will be able to predict what will be the most appropriate viewing weft for individuals based on their estimation of the emotions of a user, their activities and important occurrences in the real world. Video on demand is already a reality, but context aware music and wireless networked video on demand will be the norm with the entertainment devices of tomorrow. Surround screen systems, using veil or water droplets to project video images and collaborative multiple look for arrangements are examples of new ways in which the senses can be artistically manipulated (Peterson, 2005, Pp. 8 12). Entertainment is likely to be infl uenced by notions of temporal and spatial mobility as well as context, mood and emotion. The integration of artistic forms and technology, interactivity with a capacity for manipulating entertainment and media experiences, the use of hypermedia concept to link media elements into a personally satisfying experience, immersion which will permit entering a three dimensional environment that approaches complete entertainment and a stress on a superior ability to narrate in order to support the moment by moment mood of the individual school principal will continue to dominate entertainment in the ubiquitous age with entertainers and artists innovating to exploit the power of technology (Burnett, 2003, Chapter 1). Individual users are more likely to be closely connected to ubiquitous computing devices through cybernetic systems and this will permit a closer connection of the human form with the electronic environment (Burnett, 2003, Chapter 2). This means that the human user will be a ble to more intimately control a variety of ubiquitous devices through the motion and expression of every part of their body and as an example, dance will be able to influence music and face sack effects more closely then ever before, resulting in new and richer forms of artistic impression for the audience. Wireless or sonar tracking systems will eliminate any need to have physical connections between a human form and any ubiquitous devices, resulting in a true freedom of movement and expression with a capacity for artistically manipulating other sensory impulses for the audience. The smart entertainment space concept is illustrated in figure 4, below.The concept of anytime anywhere entertainment will mean that it will be possible to use an individuals PDA device to shop for a very wide variety of entertainment games, videos or experiences from anywhere and at anytime (Krikke, 2005, Pp. 63 64). High speed networks will deliver what has been requested in a flash and the content can be viewed on a portable PDA or a home entertainment centre which will offer more options for enhancing entertainment recreation or even interacting with the entertainment presentation. Interactivity will mean that as a story rolls on, a viewer can choose options that influence future narration and influence the present in the narration. Wideband network connectivity will mean that it will be possible to carry on with favorable interactions with distant human friends while simultaneously interacting with computer generated entertainment which may include avatars that are beamed into the homes of all those who are connected to a kind gathering which is distant in space, but close in time. solely those who are connected can interact simultaneously with the computer that is generating entertainment animations and view the results in real time. Such entertainment sessions are certainly going to need very high speed networks, immense computing power for the ubiquitous entertainmen t centres and real time processing power to put together socialisation in an augmented reality world and large amounts of data will have to be maintained in storage for rapid retrieval with such data also being rapidly moved over the ubiquitous networks.When individuals are indulging in remote interactions, such as those over videoconferencing, it is not possible to fulfil or feel the people at a distance and this means that a certain loss of emotional information currently exists in computer mediated interactions. Touch, or hepatic interaction devices that are being considered in research today and new forms of interfaces that attempt to present more emotion information by various means, such as garble changing displays or avatars will make entertainment and social interactions more fun (ISMAR, 2007, Pp. 33 35). Thus, it will be possible to further modify the tangible content of interactions involving computers. Computer generated reality will make it possible for individuals t o either learn or play games, such as squash, all by themselves using a racquet that will contain position sensors that are coupled to a computer that will fix the position of such a racquet in real time, in relation to a computer generated ball, making it possible for the user to experience the bash of a real squash game (ISMAR, 2007, Pp. 4 9 and 21 27). Many different games, including fencing, tennis, table tennis, badminton or even ice ice hockey etc will be available on the same entertainment centre, which will also provide delights of high speed driving, ice skating or piloting a jet fighter with appropriate gaming attachments. graphic interaction will be possible with contemporary art, including music and lighting patterns emanating from a music wall and this will make it possible for individuals to seek new creative and thrilling experiences (ISMAR, 2007, Pp. 47 52). New forms of interactive exhibitions will be possible for art and antiquities etc, with computer generate d avatars providing more human like guidance around museums or other interesting places (ISMAR, 2007, Pp. 53 58). It will be possible for painters and graphic artists to create on computer palettes and to surcharge their work with emotionally responsive features and a certain level of desirableness that will make their work far more interesting as compared to the paintings of today (ISMAR, 2007. Pp. 61 66). Changes in te
