Determining "Likeness" under the GATS
Publication Date: septiembre 2006Más MenosThe concept of "like services and service suppliers" used in the General Agreement on Trade in Services (GATS) is still very much uncharted territory. The few dispute cases involving national treatment and most-favoured-nation treatment claims under the GATS are vague concerning the criteria which should be used to establish "likeness". Discussions among WTO Members on this subject have remained limited and inconclusive. Perhaps the only point on which everybody agrees is that a determination of "likeness" under the GATS gives rise to a wider range of questions – and uncertainties – than under the GATT. The intangibility of services, the difficulty to draw a line between product and production, the existence of four modes of supply, the combined reference to like services and like service suppliers, and the lack of a detailed nomenclature are some of the factors which complicate the task of establishing "likeness" in services trade. This contribution focuses on the concept of “likeness” in the context of the national treatment obligation (Article XVII of the GATS). It discusses the possible implications of the combined reference to “like services and service suppliers”, as well as the relevance and role of the modes of supply in determining “likeness”. It also examines whether the criteria developed by GATT case-law (physical properties, classification, end-use and consumer tastes) can be mechanically transposed to services trade and how far they may contribute to establishing “likeness” under the GATS. It then discusses whether other parameters, such as the regulatory context or an “aim and effect” type approach could be relevant.

Services Liberalization in the New Generation of Preferential Trade Agreements (PTAs)
Publication Date: septiembre 2006Más MenosThis paper attempts to fill a gap in the trade literature by providing a comprehensive overview of services liberalization commitments in the new generation of preferential trade agreements (PTAs) as compared to prevailing GATS commitments and Doha Round offers. By developing a new database, the paper reviews the commitments undertaken by 29 WTO Members (counting the EC as one) under mode 1 (cross-border supply) and mode 3 (commercial presence) in 28 PTAs negotiated since 2000. The paper presents a general analysis from both a cross-country and cross-sector perspectives, and also examines in more detail the GATS+ commitments undertaken in a number of key sectors (audiovisual, distribution, education, financial, professional, and telecommunication services). The paper also discusses the potential economic costs arising from these preferential agreements, as well as the potential implications for the multilateral trading system, and for the Doha round of negotiations in particular. The paper concludes by discussing possible approaches to overcome the potential downsides of PTAs, including proposals for a more pro-active role for the WTO in the surveillance of these agreements.

Services Trade Liberalization at the Regional Level
Publication Date: mayo 2006Más MenosThis paper discusses the opportunities and challenges for Southern and Eastern African ACP countries of services negotiations in the context of European Partnership Agreements. The paper provides an overview of existing flows in services from and to Southern and Eastern Africa, an overview that suffers from the paucity of relevant data. Given the significant differences among services sectors, the paper provides a separate discussion for several of them, including financial services, tourism and business services. The latest developments in each sector are described and the issues that are at stake in trade negotiations. In this context the competitive position of Southern and Eastern African countries is compared with the position of the European Union and other global players. The paper attempts to identify possible export opportunities for Southern and Eastern African ACP countries and discusses the advantages and disadvantages of giving preferential access to EU suppliers in those services sectors where African countries are likely to import. Particular attention is paid to the role of mode 4 in the discussed services sectors.

Forecasting Trade
Publication Date: mayo 2006Más MenosThis paper develops a set of time series models to provide short-term forecasts (6 to 18 months ahead) of international trade both at the global level and for selected regions. Our results compare favourably to other forecasts, notably by the International Monetary Fund, as measured by standard evaluation measures, such as the root mean square forecast error. In comparison to other models, our approach offers several methodological advantages, inter alia, a focus on import growth as the core variable, the avoidance of certain difficulties affecting the performance of structural models, the selection of variables and lags on the basis of theoretical considerations and empirical testing as well as a full documentation of the modelling process.

The Impact of Disasters on International Trade
Publication Date: marzo 2006Más MenosIn this paper we examine the impact of major disasters on international trade flows using a gravity model. Our panel data consists of more than 170 countries for the years 1962-2004 yielding approximately 300,000 observations. We find that the driving forces determining the impact of such events are the democracy level and, to a lesser extent, the area of the affected country. The less democratic and the smaller a country the more are its trade flows reduced in case it is struck by a disaster. We are also able to distinguish between the effect of a disaster on an importing and an exporting country.

Liberalizing Financial Services Trade in Africa
Publication Date: marzo 2006Más MenosThis paper analyses the possible gains from regional and multilateral liberalization of financial services trade for African countries taking into account the implications of such liberalization for financial regulation and capital account liberalization. It also describes existing efforts to integrate financial markets within four African regions (WAEMU, CEMAC, SADC and COMESA) and discusses the existing GATS commitments of the relevant countries with respect to financial services. Although the regions differ significantly, there is scope for further regional integration in all of them. Significant scope also exists for further multilateral liberalization of financial services, in particular with respect to Mode 3.

Non-Reciprocal Preference Erosion Arising from MFN Liberalitzation in Agriculture
Publication Date: marzo 2006Más MenosThis paper estimates the risk of preference erosion for non-reciprocal preference recipients in the agricultural sector as a consequence of MFN tariff cuts. It is based on a simulation of a single tariff-cutting scenario. The measure of preference erosion risk is the difference in preference margins enjoyed by individual suppliers to the QUAD (Canada, EU, Japan, United States) markets before and after a MFN tariff reduction, multiplied by the associated trade flow. The paper does not attempt to determine how losses in preference margins translate into trade outcomes, but it does highlight which products and which non-reciprocal preference beneficiaries are the most vulnerable to erosion effects in the major developed country markets. Overall, the paper finds that the risk of preference erosion is small, but some countries are strongly affected in particular product lines (notably sugar and bananas).

A ‘Probabilistic’ Approach to the Use of Econometric Models in Sunset Reviews
Publication Date: febrero 2006Más MenosEconomists have increasingly become involved in trade remedy and litigation matters that call for economic interpretation or quantification. The literature on the use of econometric methods in response to legal requirements of trade policy is rather limited. This article contributes to filling this gap by demonstrating the efficacy of using a simple ‘probabilistic’ model in analyzing the ‘likelihood’ of injury to the local industry concerned, following a finding of continuation or recurrence of dumping (or countervailable subsidies). The legal concept of ‘likelihood’ is not only particularly well-suited to illustrate the systemic need for trade lawyers and economists to cooperate. It is also of imminent practical relevance with a groundswell of ‘sunset’ reviews looming on the horizon. We discuss the significance of economic analysis for trade remedy investigations by reviewing the literature, the applicable WTO rules and, in particular, the pertinent case law. The potential value of probabilistic simulations for ‘likelihood’ determinations is exemplified using a real-world application. Using data from past United States International Trade Commission investigations, we find that a probabilistic model that takes account of the uncertainty surrounding economic parameters reduces the risk of misjudging the effect on the domestic industry of a termination of trade remedies.

The Impact of Mode 4 Liberalization on Bilateral Trade Flows
Publication Date: noviembre 2005Más MenosThis paper gives insights into the possible trade creating effects of service trade liberalization via Mode 4. In particular we expect that temporary movements of persons, like permanent movements, have the potential to reduce transaction costs for merchandise trade between home and host country. Exploiting data on H-1B beneficiaries from different origins in the United States and using a gravity model of trade, we find significantly positive effects of temporary movements of persons on bilateral merchandise trade. In addition to this, the paper provides insights into the determinants of temporary movements of persons.

Multilateral Solutions to the Erosion of Non-Reciprocal Preferences in NAMA
Publication Date: octubre 2005Más MenosThis paper analyzes the risks of preference erosion arising from MFN trade liberalization in manufactured products. It focuses on developing countries that receive non-reciprocal preferences in the markets of United States, EU, Japan, Canada and Australia. The paper estimates preference margins as the difference between non-reciprocal preferential rates received by individual countries and the best available (MFN or better-than-MFN) treatment received on average by all other suppliers. Most previous work on this subject has compared the preferential rates for individual countries with MFN rates alone, which the paper found to have the effect of over-stating the margin at risk from erosion following MFN reductions. The paper also considers the effect of less than full utilization of preference margins by beneficiaries, but a lack of data prevented the inclusion of this additional moderating factor relating to erosion risk. The paper finds that developing countries as a whole do not loose from preference erosion following MFN liberalization, although significant gains and losses underlie the estimate of the average. Almost all least-developed countries either lose from preference erosion or are unaffected by it because their exports are already largely MFN duty-free. A large number of LDCs are in the latter group. The main sectors where preference erosion occurs are textiles, fish and fish products, leather and leather products, electrical machinery and wood and wood products. As regards trade solutions to preference erosion, options are somewhat limited. Improved utilization rates may help certain countries but certainly do not offer a generalized solution. Limited scope exists for expanding the coverage of preference schemes within the destination markets considered in the paper. Other destination markets might offer some prospect, but these are limited by the fact that the markets studied dominate the trade flows of the beneficiary countries.

The Economic Impact of EPAs in SADC Countries
Publication Date: agosto 2005Más MenosThe Cotonou Agreement introduces new fundamental principles with respect to trade between the European Union and African, Caribbean and Pacific countries relative to the Lomé Convention: in particular non-reciprocal preferential market access for ACP economies will only last until 1 January 2008. After that date, it will be replaced by a string of Economic Partnership Agreements meant to progressively liberalise trade in a reciprocal way. The progressive removal of barriers to trade is expected to result in the establishment of Free Trade Agreements between the EU and ACP regional groups in accordance with the relevant WTO rules and help further existing regional integration efforts among the ACP. In this paper, an applied general equilibrium model (15 regions, 9 sectors) is used to simulate the impact of EPAs for countries of the Southern African Development Community. The standard Global Trade Analysis Project (GTAP) model has been extended to include the elimination of textile quotas, EU enlargement to 25 members as well as tax revenue sharing and a common external tariff among Southern African Customs Union countries. A number of comparisons between different scenarios are undertaken, in particular: (i) the EPA scenario is compared to the multilateral liberalization scenario; (ii) SADC liberalization with the EU only is compared to a scenario with simultaneous regional integration among African economies and to the case of the EU also signing an FTA with Mercosur; and (iii) a complete reduction of import barriers is contrasted with partial liberalization (i.e. only 50 per cent tariff reductions in agriculture) and with full trade liberalization that includes the elimination of subsidies. The issue of tariff revenue loss is also addressed and the required tax replacement is calculated. Selected experiments are re-run under an unemployment closure. Simulation results show that EPAs with the EU are welfare-enhancing for SADC overall, leading also to substantive increases in real GDP. For most countries further gains may arise from intra-SADC liberalization. The possibility of the EU entering an FTA with other countries, such as Mercosur, reduces estimated gains, but they still remain largely positive. Similarly, estimated gains need to be revised downwards if agriculture liberalization is not as far reaching as a reduction of import barriers for manufactures. At the sectoral level, the largest expansions in SADC economies take place in the animal agriculture and processed food sectors, while manufacturing becomes comparatively less attractive following EU-SADC liberalization. Interestingly, multilateral liberalization would instead foster some of the manufacturing sectors (textile and clothing and light manufacturing). Results also show the need for the SACU tariff pooling formula to be adjusted to reflect new import patterns as tariffs are removed.

Public Services and the GATS
Publication Date: julio 2005Más MenosThe status of public services is one of the most hotly debated issues surrounding the GATS. There are two approaches to distinguish such services from any other services: an institutional approach that focuses on the legal and institutional conditions governing supply (e.g. ownership status, market organisation), and a functional approach based on the policy objectives that may be involved (e.g. distributional and quality-related considerations, concepts of universal access). Given the wide range of institutional arrangements that exist in different jurisdictions, with significant variations over time, the former approach does not appear appropriate. The services provided by government-owned facilities, whose costs are covered directly by the State, may well be indistinguishable, for all practical purposes, from the services provided by private commercial operators, whose users (students, patients, passengers, etc.) are reimbursed. This paper discusses the relevance of the GATS for different organisational settings - from government monopolies to regulated and/or subsidized private provision - that may be used by WTO Members to meet typical public service objectives. It turns out that virtually all forms of organisation can be accommodated within the framework of the Agreement. To fully exploit its opportunities and avoid unpleasant surprises, however, governments would need to thoroughly analyse the relevant provisions in the light of their own policy objectives.

Environmental Quality Provision and Eco-Labelling
Publication Date: junio 2005Más MenosThis paper is a literature survey of some relevant issues arising from environmental quality provision and eco-labelling schemes. First of all it is shown how the two topics are strictly related. Firms adopting a production process (or producing a good) more environmentally friendly than others (environmental quality provision aspect) may want to make it public (eco-labelling aspect). The survey addresses the question of optimal environmental quality provision (also as a policy tool) and firms compliance. With regard to eco-labelling, its impacts on market structure are analysed. It hasn’t been possible to consider all issues, like for example that of moral hazard in providing non truthful information. Different issues related to trade are also analysed, even if the literature is not abundant on this yet. In the literature both aspects, of environmental quality provision and eco-labelling, are analysed using product differentiation models. The usual result is that multiple equilibria arise depending also on the parameters. Models are also not robust to different assumptions. Environmental quality provision and eco-labelling are also compared to more traditional policy instruments like taxes (or subsidies) and standards. From the empirical evidence it can be concluded that information plays a crucial role both for consumers’ and producers’ decisions. Consumers are willing to pay a higher price to be informed about the greenness of a good, and a label can really be a determinant in their choice of which brand to purchase. On the supply side, disclosing information about the environmental performance of a firm can affect investment decisions and its stock value.

Turning Hills into Mountains?
Publication Date: marzo 2005Más MenosOver the past months, it has become increasingly clear that the services negotiations under the Doha Development Agenda will not produce significant improvements on current commitments unless major new impetus is provided. In an introductory section, this paper discusses various impediments, from the perspective of participating governments, that may explain the lack of negotiating momentum to date. It then provides an overview of existing commitments under the GATS (by sector, mode of supply, and level of development) and of the initial offers that had been tabled by early 2005. Despite the substantial benefits that may be associated with the liberalization of services trade, the GATS has obviously not yet lived up to ambitious expectations. For example, on average across all WTO Members, only one-third of all services sectors have been included in current schedules of commitments; and many entries have been combined with significant limitations on market access and national treatment or with the complete exclusion of particular types of transactions (modes of supply) from coverage. While the ongoing services negotiations provide an opportunity to complement the rule-making efforts of the Uruguay Round with genuine market opening, many governments apparently have found it difficult, despite generally more restrictive access regimes and, thus, potentially higher gains from liberalization than in merchandise trade, to undertake or envisage economically significant bindings across a broad range of services. Five years after the inception of the services round, current negotiating arrangements, based mainly on (bilateral) exchanges of requests and offers, may need to be complemented by common points of reference to provide greater focus and guidance.

Developing Countries in the WTO Services Negotiations
Publication Date: noviembre 2004Más MenosThe aim of this paper is to analyse developing countries’ participation so far in the current round of services negotiations under the Doha Development Agenda. The paper analyses developing countries’ negotiating positions, as evidenced by their multilateral negotiating proposals; their initial offers; and, to the extent allowed by the incomplete and sketchy information available, their participation in bilateral market access negotiations. A number of basic themes are raised: the essential role of services for economic development; the high costs imposed by trade protection; the benefits of liberalization; the need to make use of the WTO forum to enhance credibility and sustain domestic regulatory reform programmes; the challenges of regulatory reform and the importance of appropriate sequencing; and the benefits arising from seeking further market access overseas in those areas where developing countries have a comparative advantage.

The Impact of Mode 4 on Trade in Goods and Services
Publication Date: noviembre 2004Más MenosThis paper estimates the impact of liberalization of temporary movements of individual service suppliers on trade in goods and services. In particular, the paper looks at the impact of the so-called forth mode to provide a service on trade in services under the other three modes: cross-border service supply (Mode 1), consumption abroad (Mode 2) and commercial presence abroad (Mode 3). Estimates are obtained using a gravity model of trade augmented for a measure of temporary movements of service suppliers. Estimates of the size of a country’s Mode 4 trade in services are based on specific information regarding the number of temporary foreign workers occupied in the service sector and their estimated average earnings, thus overcoming the limitations of traditional measures of Mode 4 based on remittances or compensation for employees. We find a positive and significant effect of temporary movements of service providers on merchandise trade and services trade under Mode 1 and 3. No significant relationship is found between services trade under Mode 2 and Mode 4.

The GATS Turns Ten: A Preliminary Stocktaking
Publication Date: agosto 2004Más MenosThe paper discusses the experience to date with the implementation and application of the General Agreement on Trade in Services (GATS), some ten years after its entry into force. One striking observation is the smooth functioning of the Agreement, which has created far less tensions and frictions, including at Ministerial Meetings, than its difficult negotiating history might have suggested. This is due in large part to a high degree of flexibility at several levels: Members have more scope than under the GATT to depart from common horizontal obligations, in particular the MFN principle; they are able to adjust the breadth and depth of their trade commitments (market access and national treatment) to particular sector conditions; and they face less constraints, if any, in the use of trade-related policies such as subsidies, export restrictions, or domestic regulatory interventions. An additional source of flexibility is the uncertainty still surrounding a few core concepts of the Agreement and their sometimes daring application in individual schedules. While the ongoing negotiations also provide an opportunity for technical corrections of scheduling problems, the basic (built-in) flexibility elements of the Agreement - including the bottom-up approach of undertaking sector commitments and the possibility of inscribing limitations under individual modes - will, of course, persist. (Their actual relevance may, nevertheless, differ significantly between 'old' Members and countries negotiating their accession to the WTO.) Given the broad reach of of the Agreement in terms of membership, sector application, and modal coverage, flexibility may be considered a conditio sine qua non. There is little reason to believe that a more rigid structure would have been acceptable to Uruguay Round participants and, even if so, that it would have proven stable and resilient over time. However, flexibility may come at a cost: lack of meaningful obligations across a reasonably broad range of service sectors. Vested interests may find it far easier than under the GATT to defend their privileges and defy more rational and harmonized trading conditions. While the paper discusses formula-based approaches that have been proposed to improve the quantity and/or quality of sector commitments within the existing framework of GATS, there should be no illusion about the scope for technical solutions to what constitutes a political and institutional challenge.

Infrastructure and Trade
Publication Date: agosto 2004Más MenosThis paper explores the role that quality of infrastructure has on a country's trade performance, estimating a gravity model that incorporates bilateral tariffs and a number of indicators for the quality of infrastructure. The paper looks at the impact of the quality of infrastructure (road, airport, port and telecommunication, and the time required for customs clearance) on total bilateral trade and on trade in the automotive, clothing and textile sectors. In order to obtain unbiased estimators, multilateral resistances for tariffs and remoteness are introduced in the gravity equation. Moreover, the robustness of the results is tested by estimating a fixed-effect model, where bilateral indexes of the quality of infrastructure are included. The results can be summarised in four main findings: (i) bilateral tariffs, generally neglected in gravity regression of bilateral flows, have a significant negative impact on trade; (ii) quality of infrastructure is an important determinant of trade performance; (iii) port efficiency appears to have the largest impact on trade among all indicators of infrastructure; (iv) timeliness and access to telecommunication are relatively more important for export competitiveness in the clothing and automotive sector respectively.

Special and Differential Treatment in the WTO
Publication Date: mayo 2004Más MenosSpecial and differential treatment (S&D) for developing countries continues to be a defining feature of the multilateral trading system. This paper seeks to address key aspects of what has become an increasingly entangled and multi-faceted discussion. The paper begins by reviewing the historical context in which the relationship of developing countries with the multilateral trading system evolved. The paper distinguishes several elements in the case typically made for S&D. It argues that concerns about graduation — the definition of which countries qualify for special treatment —have complicated progress on this issue, suggesting that a focus on measures rather than on country status would obviate this difficulty, while at the same time increasing the analytical underpinning of the case for special and differential treatment. The paper explores various forms of S&D and develops arguments for particular approaches to the design and management of access to S&D. An illustration is provided of how a more analytical approach would work by defining eligibility automatically in relation to measures rather than countries.

Institutions, Trade Policy and Trade Flows
Publication Date: abril 2004Más MenosThis paper analyses to which extent domestic institutions affect trade flows. We use two complementary approaches, one focusing on the size of total trade flows and one focusing on bilateral trade patterns (gravity equation). Besides, we control for two other domestic policy variables: trade policy and domestic infrastructure. We find that the quality of institutions has a positive and significant impact on a country’s level of openness. Domestic tariffs have no statistically significant impact on their own, but do affect total trade flows when combined with good institutions. Domestic institutions also have a positive and significant impact on bilateral trade flows, but the parameter of our institution variables is reduced by almost a half and may turn insignificant when the quality of domestic infrastructure is included in the regression.
