We exploit a decomposition of gross trade flows into their value added components to reassess the relationship between increased imports from China and manufacturing jobs in US local labour markets following the seminal paper of Autor, Dorn, and Hanson (2013, ADH).

This 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.

The geography of global value chains (GVCs) depends crucially on trade costs between countries hosting various stages of production. Some stages might be more sensitive to trade costs than others. In this paper, we exploit a value-added decomposition of bilateral trade flows to distinguish low value-added GVC trade typically associated with production stages such as assembly, from high value-added GVC trade associated with stages such as R&D and design. We test the hypothesis that low value-added stages will more easily reroute given changes in trade costs between importing and exporting countries than high value-added stages.

Tariff water –the difference between bound and applied duties– provides relevant information on domestic trade policy and WTO trade negotiations. This paper examines the general and sectoral tariff structure of 120 economies, using exploratory data analysis.

The paper reviews a number of issues related to the use of currencies in international trade, more than one decade after the introduction of the euro and shortly after steps taken by the Chinese authorities to liberalize the use of the RMB in off-shore markets. Trade is an important factor in establishing a currency as an international currency, notably by fulfilling the transaction/medium of exchange and unit of account motives of currency demand. A well prepared liberalization of currency use for international trade and foreign direct investment transactions can even be helpful in achieving the international investment and reserve currency status. While in the distant past the later was also linked to preponderance of a country in trade markets, it is now linked to the prevalence of the currency in international financial transactions, which supposes that the country in question engages at least partly in some liberalization of capital account transactions. This paper shows theoretical and practical reasons explaining the current dominance of the US dollar and the euro in the invoicing of international trade. There is little doubt, though, that in the medium-to-long term the RMB will become a major currency of settlement in international trade. This is not only the current direction of government policy but also that of markets, as evidenced by the rapid expansion of off-shore trade payments in that currency. In the meantime, though, the US dollar and the euro are enjoying a nearduopoly as settlement and invoicing currencies in international trade. The stability of this duopoly is enhanced by a number of factors recently highlighted by economic analysis: coalescing, "thick externalities" and scarcity of international currencies are useful to explain that, until such time that RMB payments match at least the share of China in global trade, the US dollar and of the euro will remain the main currencies in the invoicing and payment of international trade. Section 1 looks at the factors that determine the use of currencies in the invoicing and settlement of international trade. Section 2 looks at the actual reality of currency use for international trade flows, and short-term prospects for the development of a possible alternative to the use of the US dollar and the euro (in particular in Asia), the RMB.

The creation of the General Agreement on Trade in Services (GATS), in the Uruguay Round, and its entry into force in 1995 marked a new stage in the history of the multilateral system. It was motivated essentially by the rapid expansion of international services trade within an increasingly open environment in many countries. Given the peculiarities of services trade, including the intangible nature of the products concerned and the need for direct contact between supplier and user in many cases, the Agreement contains a variety of conceptual innovations, including its extension to modes of supply beyond conventional cross-border trade (consumption abroad, commercial presence, and presence of natural persons) and its coverage, and legitimization, of various types of non-tariff restrictions. In turn, the new concepts needed time to be absorbed by the ministries and agencies involved in services trade. Further, the positive-list, or bottom-up, approach to scheduling trade commitments under the GATS meant that great flexibility was given to Members in selecting the sectors concerned and specifying the levels of access provided under individual modes. Thus, not surprisingly, the schedules that emerged from the Uruguay Round, which still account for the majority of current commitments, contain a variety of unclear or superfluous entries that may cause interpretation problems. Their solution could contribute significantly to the clarity and comparability of access obligations across sectors and WTO Members. The scheduling conventions agreed for the Doha Round thus provide specifically for the possibility of technical refinements that leave the substance of commitments unchanged. However, not only was this possibility used more sparingly to date than might have been expected, but additional flaws would be introduced if some current offers were to enter into effect. The following discussion, with a focus on a particular group of entries (market access via commercial presence), tries to explain the scope for such refinements and develop a clearer picture of the areas where further action might be needed.

The paper studies empirically the fiscal policy instruments by which governments try to influence election outcomes in 24 developing countries for the 1973-1992 period. The study finds that the main vehicle for expansionary fiscal policies around elections is increasing public expenditure rather than lowering taxes, and public investment cycles seem particularly prominent. Institutional mechanisms which constrain discretionary expenditure policies and which strengthen fiscal control are therefore worthwhile considering to prevent opportunistic policy making around elections.

The GATS does not offer a definition of "services", but services need to be identified and classified for the operation of the Agreement, especially for the scheduling of specific commitments on market access and national treatment. There is no obligation on WTO Members to use any particular classification system in undertaking commitments. Nevertheless, an informal document produced for the services negotiation during the Uruguay Round, the Services Sectoral Classification List (W/120), was used and continues to be used as the principal guiding classification system, not only in the WTO, but also in bilateral and plurilateral services trade negotiations outside of the WTO. WTO jurisprudence has also noted the role of W/120 in the determination of sectoral coverage of GATS commitments. However, services classification does not receive enough attention it deserves. This paper attempts to make contribution by providing an overview of services classification and highlighting its relevance to both trade negotiations and WTO dispute settlement. It consists of four sections. Section I reviews how a services classification system was introduced into the multilateral trading system and describes the main features of W120. Section II takes a closer look at some aspects of the classification system, drawing attention to challenges in its application, which arise from inter alia services with multiple end-uses, overlaps between sectors, and the issue of "new services". Section III considers the implications of classification on GATS commitments by examining a number of WTO dispute settlement cases. Section IV concludes. In conclusion, the paper underlines the importance of services classification in assisting governments in clearly and accurately undertaking commitments. It also notes that WTO Members have taken or suggested various pragmatic approaches to addressing challenges in the application of the current services classification system. The proposed approaches again highlight the role of classification in ensuring the clarity, certainty and predictability of specific commitments in services.

This paper studies the factors of comparative advantage within global value chains relying on a framework where comparative advantage is measured through the interaction of country and industry characteristics.

This 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.
