A propos de l’OMC

Proper measurement and aggregation of trade costs is of paramount importance for sound academic and policy analysis of the determinants - particularly those of policy - of economic outcomes. The international trade profession has witnessed signifcant new developments, both on the theoretical and on the empirical side, concerning the measurement and decomposition of such costs into variable and fixed costs on the one hand and into partial and general equilibrium effects on the other hand.

This paper argues that interests of nationals and owners of home-based foreign capital in the formation of a Trade Agreements (TA) are not antagonistic, except under rather particular assumptions on initial tariffs among potential members. Further, if initial tariffs are endogenously determined through an industry-lobbying process, then TA that would have been immiserising in the absence of Foreign Direct Investment (FDI), may be welfare-enhancing in the presence of foreign-owned firms. The rationale is linked to the effect that the entry of FDI has on the pre-TA tariff, through contributions to the incumbent government. These results may help explain recent integration programs between developed and developing countries.

This paper reviews a number of initiatives taken by public and private institutions aimed at minimizing the impact of the on-going crisis of the financial sector on its ability to supply trade finance to support trade at affordable rates. In doing so, it draws a few policy lessons. One of them is that a relatively stable segment of the financial industry is now regularly hit by the contagion of financial crises, with potentially very harmful spill-overs on global trade through a dry up of its financing. Specific policy measures to restore confidence in this otherwise safe market required a good level of coherence and dialogue between national governments and international and regional development organizations. Lessons from the Asian and Latin American financial crises of the late 1990's have been learned and academia provided input by developing understanding on a previously under-rated topic in the literature. Learning-by-doing and leadership have also been features of the policy response, which altogether had some successes. Still, longer-term challenges remain, such as addressing the structural gaps in the availability of trade finance in low-income countries - ad hoc programs have been designed to fill the gap between the perceived and actual risk of extending trade credit to traders in these countries. Moreover, regulation of the trade finance market needs to continue to take into account its low-risk character, the absence of leverage and its impact on development.

A growing literature suggests that high-income countries export high-quality goods. Two hypotheses may explain such specialization, with different implications for welfare, inequality, and trade policy. Fajgelbaum, Grossman, and Helpman (JPE -2011-) formalize the Linder (1961) conjecture that home demand determines the pattern of specialization and therefore predict that high-income locations export high-quality products. The factor-proportions model also predicts that skill-abundant, high-income locations export skill-intensive, high-quality products (Schott, QJE 2004). Prior empirical evidence does not separate these explanations. I develop a model that nests both hypotheses and employ microdata on US manufacturing plants’ shipments and factor inputs to quantify the two mechanisms’ roles in quality specialization across US cities. Home-market demand explains at least as much of the relationship between income and quality as differences in factor usage.

The last 25 years have witnessed a rapid increase in regional trade agreements (RTAs). Although RTAs generally aim at lowering tariff and non-tariff trade barriers, an increasing number of trade agreements extend their scope to cover specific policy areas such as environmental protection and sustainable development. This paper establishes a comprehensive typology and quantitative analysis of environment-related provisions included in RTAs. The analysis covers all the RTAs currently into force that have been notified to the WTO between 1957 and May 2016, namely 270 trade agreements. While environmental exceptions, along with environmental cooperation continue to be the most common types of environment-related provisions, many other different types of provisions are incorporated in an increasing number of RTAs. The common feature of all environment-related provisions, including environmental exceptions, is their heterogeneity in terms of structure, language and scope.

The rapid rise in global fragmentation — foreign investment, global supply chains, and ‘production sharing — is fundamentally reshaping the multilateral trading system. This paper uses a simple economic modeling framework to understand how the global fragmentation phenomenon may reshape the WTO, and particularly its developing country members that are most affected by the rise in global production sharing and foreign direct investment. The paper argues that the surge in global production sharing, supply chain agreements, and investment has not only recast the role of existing GATT/WTO rules, but that these same forces also create a strong rationale for new multilateral disciplines pertaining to investment incentives and other ‘behind-the-border’ policies.

The WTO's plurilateral Agreement on Government Procurement ("the GPA" or "the Agreement") is an important ongoing success story for the Organization. In March 2012, the GPA Parties completed a comprehensive revision of the Agreement, encompassing both its text and coverage (market access commitments). The revised GPA, the negotiating processes that led to its adoption and coming into force, and the continuing gradual broadening of its membership are of therefore interest for the evolution of the international trading system. The GPA's successful renegotiation, the continuing growth of its membership and its vitality as an instrument of public policy were not achieved through happenstance. The paper discusses a number of specific design features of the GPA that clearly facilitated the successful conclusion of the renegotiation and that, as such, may in the future be relevant to other areas of global trade liberalization. In addition to the Agreement's plurilateral nature, of particular interest are the approach taken with respect to application of the most-favored-nation (MFN) principle in the Agreement; the GPA's continuing strong emphasis on principles of reciprocity in market access concessions; and its approach to special and differential treatment for developing countries, in all of which it differs from approaches that are widely used in other WTO Agreements. Apart from the above, the GPA revision is important for the merging of trade and good governance concerns that it exemplifies. As discussed in the paper, the themes of governance and the sound management of public resources that are treated in the revised Agreement were not afterthoughts to the renegotiation; rather, they permeated the revised text and received focused attention from the Parties in their own right. As well, the GPA has direct implications for investment policy and for domestic economic reforms, and is an important tool of e-commerce. And, the revision has made possible very significant synergies between the GPA and other international instruments and activities in reducing barriers to participation and strengthening governance in public procurement markets. For all these reasons, the revised Agreement is likely to have a wider impact than meets the eye, and well merits the support and attention that it has received from the participating WTO Member governments.

This 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).

Competition policy, today, is an essential element of the legal and institutional framework for the global economy. Whereas decades ago, anti-competitive practices tended to be viewed mainly as a domestic phenomenon, most facets of competition law enforcement now have an important international dimension. Examples include: the investigation and prosecution of price fixing and market sharing arrangements that often spill across national borders and, in important instances, encircle the globe; multiple recent, prominent cases of abuses of a dominant position in high-tech network industries; important current cases involving transnational energy markets; and major corporate mergers that often need to be simultaneously reviewed by multiple jurisdictions.

Trade finance has received special attention during the financial crisis as one of the potential culprits for the great trade collapse. Several researchers have used micro level data to establish the link between trade finance and trade, especially so during the financial crisis, and have found diverting results. This paper analyses the effect of trade credit on trade on a macro level through a whole cycle. We employ Berne Union data on export credit insurance, the most extensive dataset on trade credits available at the moment, for the period of 2005--2011-. Using an instrumentation strategy we can identify a significantly positive effect of insured trade credit, as a proxy for trade credits, on trade. The effect of insured trade credit on trade is very strong and remains stable over the cycle, not varying between crisis and non-crisis periods.
