WTO Working Papers
WTO working papers usually represent research in progress. Such research may be conducted in the preparation of WTO Secretariat reports, studies or other material for WTO members. The papers are circulated for comment because the WTO considers critical review of professional research to be extremely important.

The Economic Impact of EPAs in SADC Countries
Publication Date: août 2005Plus MoinsThe 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: juillet 2005Plus MoinsThe 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: juin 2005Plus MoinsThis 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: mars 2005Plus MoinsOver 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: novembre 2004Plus MoinsThe 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: novembre 2004Plus MoinsThis 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: août 2004Plus MoinsThe 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: août 2004Plus MoinsThis 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: mai 2004Plus MoinsSpecial 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: avril 2004Plus MoinsThis 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.

National Environmental Policies and Multilateral Trade Rules
Publication Date: janvier 2004Plus MoinsThis paper provides an overview of institutional, economic and legal aspects of the relationship between national environmental policies and the multilateral trading system. In particular, it analyses some of the difficulties the WTO Dispute Settlement System faces when having to evaluate disputes on national environmental policies that have an impact on trade. From an economist's point of view it would be desirable that optimal environmental policies, i.e. policies that correct existing market failures, be ruled consistent with multilateral trade law. This paper argues that WTO law in theory provides appropriate tools to ensure rulings that are consistent with economic thinking. Yet, the paper also argues that economists have a rather imperfect knowledge of the precise welfare effects of different types of environmental policies. In practice, therefore, it is questionable whether economists are able to give adequate guidance to legal experts when it comes to the evaluation of national environmental policies. This is one of the reasons why there continues to be some degree of uncertainty as to the possible interpretations of certain WTO rules in the context of environmental disputes.

Vertical Specialization and the Quality of Infrastructure
Publication Date: décembre 2003Plus MoinsThis paper explores the role of producer services and ICT on international outsourcing. The motivation for outsourcing is to focus on core business and improve efficiency and outsourcing companies usually outsource a number of functions and the efficiency gains depend on the ability for the suppliers to deliver the required quality at the right time. The timeliness of delivery and the fulfilment of quality standards depend critically on the availability of producer services. I therefore argue that international outsourcing can best be understood within an analysis framework of many suppliers that are interdependent, and the O-ring theory of production is such a theory. The paper first presents and modifies this model and then explores its predictions in an empirical analysis of the determinants of international vertical specialization as defined by an index developed by Hummels et al. (2001). The index is calculated for a cross-section of 52 countries and 5 sectors and regressed on a number of variables affecting the timeliness of delivery. It is found that vertical specialization is sensitive to trade barriers and infrastructure quality and cost of infrastructural services. The relative importance of trade barriers and various indicators of infrastructure vary between sectors. Vertical specialization in the electronics sector appears to be most sensitive to trade barriers and the density of the telecommunication network. This is also the case for the motor vehicles sector, but the size of the parameters is somewhat lower. The chemicals sector is most sensitive to the restriction on maritime services, while for textiles and clothing the aggregated measure of infrastructure had the highest explanatory power. Only in the electronics sector did the wage level (GDP per capita was used as a proxy) matter for vertical specialization.

Is Trade Liberalization a Window of Opportunity for Women?
Publication Date: août 2003Plus MoinsThis paper analyses how trade affects women's job opportunities and earnings through five case studies: Mauritius, Mexico, Peru, the Philippines and Sri Lanka. It is found that women's share of the labour force has increased over time and the wage gap between men and women has narrowed. It is also found that there is a positive and statistically significant relation between exports and women's share of employment while there is a statistically significant and negative correlation between women's share in employment and imports. The correlation between women's share of employment and trade stems from variation between sectors rather than within sectors over time, indicating that export-competing industries tend to employ women while import-competing industries tend to employ men. Trade liberalization is likely to create jobs for women and over time increase their relative wages.

ICT, Access to Services and Wage Inequality
Publication Date: août 2003Plus MoinsThis paper discusses how information and communication technology (ICT) affects the quality and reach of consumer services. These services need to be provided locally, but consist of several components, some of which can be digitised and transmitted over long distances. A general equilibrium model is developed and numerical simulations in a stylised two-factor, two-region, centre-periphery setting are presented. Trade in intermediate services improves the quality of consumer services enormously in the periphery, but may reduce the quality at the centre. Trade in intermediate services also has a dramatic impact on skilled workers’ wages in the periphery, both relative to unskilled workers in their own region and relative to skilled workers at the centre and leads to a more equal distribution of income both between the centre and the periphery and within the periphery.

Fragmented Production
Publication Date: août 2003Plus MoinsThis paper explores the impact of vertical specialization on world trade within the framework of the O-ring theory of production. Within such a framework there is little scope for substituting quantity for quality or for gaining market shares by undercutting established suppliers purely on cost. Furthermore, quality requirements will increase as lead firms in the supply chain invest in technology that reduces inventory and speeds up the production process. It is shown that potential suppliers in low-cost countries will only have an incentive to upgrade quality if adequately efficient infrastructure, logistics and customs procedures are in place. Changing trade patterns between USA and Mexico and China suggests that proximity and low trade barriers are important determinants of the extent and nature of vertical specialization. Thus, a larger share of Mexico's trade with USA is driven by vertical specialization than China's trade with USA. Nevertheless, China has caught up with Mexico as far as share in US total imports is concerned, and the market share gap has narrowed even in electronics, the sector in which vertical specialization is most prominent. It appears that vertical specialization adds to total world trade rather than replacing traditional trade flows.

Effects of WTO Accession on Policy-Making in Sovereign States
Publication Date: avril 2002Plus MoinsThe purpose of the paper is to discuss the effects of WTO accession on policy-making and institutional reforms in transition countries. This is done by looking at the experience of those transition countries which are already Members of the WTO. We start by examining the effect of accession on trade policy and distinguish between the effects of accession negotiations and those of autonomous policy initiatives. We find that no precise blueprint of accession conditions can be ascertained, that WTO played a role, albeit not an exclusive one in the process of liberalization, that the costs of WTO Membership are not negligible, that the benefits of WTO Membership are also significant in terms of a better market access, improved governance and a recourse to better economic policies.

Product Labeling, Quality and International Trade
Publication Date: février 2002Plus MoinsThis paper analyzes the reasons why countries may pursue different labeling policies in autarky and how this affects countries’ welfare in the context of international trade. In an asymmetric information environment where producers know the quality of the goods they are selling and consumers are not able to distinguish between them, the quality governments choose to protect by a label depends on consumer preferences for and production costs of different qualities. Countries with different distributions of tastes and/or different production functions will thus decide to label differently. When they trade, welfare effects will be different on the country as a whole and on different types of consumers within each country depending on whether countries choose to mutually recognize each others labeling policy or to harmonize their policies. In particular it will be the case that a country with weak preferences for high quality will oppose the introduction of an international, harmonized label as it is better off under a regime of mutual recognition. When countries only differ in their costs of producing quality instead, none of the trading partners will lose from a move towards trade under an international, harmonized label.

The Impact of Transparency on Foreign Direct Investment
Publication Date: novembre 2001Plus MoinsNon-transparency is a term given in this paper to a set of government policies that increase the risk and uncertainty faced by economic actors foreign investors. This increase in risk and uncertainty stems from the presence of bribery and corruption, unstable economic policies, weak and poorly enforced property rights, and inefficient government institutions. Our empirical analysis shows that the degree of non-transparency is an important factor in a country's attractiveness to foreign investors. High levels of non-transparency can greatly retard the amount of foreign investment that a country might otherwise expect. The simulation exercise presented in the statistical part of this paper reveals that on average a country could expect 40 percent increase in FDI from a one point increase in their transparency ranking. Pari passu, non-transparent policies translate into lower levels of FDI and hence lower levels of welfare and efficiency in the host country's economy. A nation that takes steps to increase the degree of transparency in its policies and institutions could expect significant increases in the level of foreign investment into their country. This increased investment translates into more resources, which in turn increases social welfare and economic efficiency.

Can Trade Policy Help Mobilize Financial Resources for Economic Development?
Publication Date: août 2001Plus MoinsThe linkages between trade and resource mobilization are complex and not well defined in theory. To what extent does trade policy affect resource mobilization and what are the mechanisms? We argue that trade policy is a key factor of influencing the domestic fundamental balance between aggregate savings and investment. The main effect of trade policy on resource mobilization stems from its contribution to static and dynamic gains from trade. But the effect of trade policy on the supply of financial resources also operates through several channels including through linkages of trade policy with foreign investment, government revenues, income distribution, foreign aid. The paper looks at direct and indirect channels, and makes a distinction between short and long term effects of different trade strategies. We also briefly review trade barriers in goods and services affecting developing countries and the potential gains from further liberalization. The long term gains from trade liberalization are substantial, but they may have to be set against short-term adjustments costs. The latter could and should be reduced by effective institutional and tax reforms.

Investment Policies and Telecommunications Regimes
Publication Date: août 2001Plus MoinsThe revolution in the telecommunication industry of recent years raises a number of interesting economic questions with significant policy implications. One of these questions is the extent to which foreign investments in the telecommunication industry is accompanied by policies that are conducive to cross–border investments. These policies can be both domestic and international. The discussion in this paper is limited to the latter by concentrating on the role of the WTO and other international agreements. The purpose of the paper is to evaluate the GATS/Telecom Agreement. This is done by looking at the guiding principles for negotiating market access for foreign investors, by comparing the Agreement with the Telecom Agreement under NAFTA and by discussing the merits of the multilateral approach to negotiating foreign investment in the telecommunication sector. The WTO GATS/Telecom Agreement comes out rather well from this evaluation exercise.
