WTO Working Papers

In spite of their growing importance in international trade as well as in bilateral and multilateral trade negotiations, services have only attracted limited attention from researchers interested in determinants of trade policies and trade cooperation. This paper seeks to account for countries' varying levels of market access commitments under the multilateral General Agreement on Trade in Services (GATS). I develop an argu Read More

The paper discusses a number of issues related to the treatment of trade credit internationally, a priori (treatment by banking regulators) and a posteriori (treatment by debtors and creditors in the case of default), which are currently of interest to the trade finance community, in particular the traditional providers of trade credit and guarantees, such as banks, export credit agencies, regional development banks, and multila Read More

We examine the effects of transit, documentation, and ports and customs delays on Africa’s exports. We find that transit delays have the most economically and statically significant effect on exports. A one day reduction in inland travel times leads to a 7 percent increase in exports. Put another way, a one day reduction in inland travel times translates into 1.5 percentage point decrease in all importing-country tariffs. In c Read More

It is becoming increasingly important to put freshwater issues in a global context. Local water depletion and pollution are often closely tied to the structure of the global economy. With increasing trade between nations and continents, water is more frequently used to produce exported goods. International trade in commodities implies long-distance transfers of water in virtual form, where virtual water is understood as the volu Read More

In this report we first give a brief overview of trade in seafood and seafood production. We then review the basic bioeconomic theory of the fishery and pinpoint why fisheries are different from most other industries. We next review the theoretical literature on trade and renewable resources that shows how unconventional outcomes from trade liberalization can emerge. Given this background, we discuss the most important policy Read More

This paper provides a review of current thinking on the economics of international trade in mineral resources. There is not a great deal written on this topic, and so my review is necessarily broad rather than deep. In some cases I am only able to cite related and even tangential literature. I first define what is meant by trade in mineral resources. I then discuss patterns of trade in mineral resources. The paper then moves on to t Read More

The General Agreement on Trade in Services (GATS) is broader in policy coverage than conventional trade agreements for goods and, at the same time, offers governments more flexibility, in various dimensions, to tailor their obligations to sector- or country-specific needs. An overview of existing commitments on healthcare and health insurance services shows that WTO Members have made abundant use of these possibil Read More

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.

We consider the purpose and design of the World Trade Organization (WTO) and its predecessor, GATT. We review recent developments in the relevant theoretical and empirical literature. And we describe the GATT/WTO architecture and briefly trace its historical antecedents. We suggest that the existing literature provides a useful framework for understanding and interpreting central features of the design and practice of Read More

I propose a framework within which to interpret and evaluate the major reforms introduced to the GATT system in its transition to the WTO. In particular, I examine the WTO Agreement on Safeguards that has replaced the GATT escape clause (Article XIX), and the Dispute Settlement Process (DSP) that resembles a court of law under the WTO. Using this framework, I interpret the weakening of the reciprocity principle Read More

The article analyses the role of international supply chains as transmission channels of a financial shock. Because individual firms are interdependent and rely on each other, either as supplier of intermediate goods or client for their own production, an exogenous financial shock affecting a single firm, such as the termination of a line of credit, reverberates through the productive chain. The transmission of the init Read More

Using a dataset of 138 countries over a period from 1966 to 2004, this paper analyses the relevance of country specific shocks for income volatility in open economies. We show that exposure to country specific shocks has a positive and significant impact on GDP volatility. In particular, we find that the degree to which the cycles of different trading partners are correlated is more important in explaining exporters’ GDP volatility t Read More

Two institutions provide multilateral venues for countries to discuss food safety measures at the international level: the Codex Alimentarius Commission (Codex) and the World Trade Organization. Both institutions encourage their members to base food safety standards on scientific evidence. In this paper we provide a description of how food safety related scientific evidence is generated and how it is used in the con Read More

Recent empirical evidence has shown that trade liberalization promotes innovation and productivity growth in individual firms. This paper argues that different types of trade liberalization – multilateral versus regional – may lead to different R&D and productivity levels of firms. Trade agreements between countries are modelled with a network: nodes represent countries and a link between the nodes indicates the exist Read More

WTO arbitrators rely on economics to establish the permissible retaliation limits authorized by the Dispute Settlement Understanding (DSU) which arguably serves to enforce the overall agreement. We examine how theoretical and quantitative economic analysis has and can be used in this stage of the DSU process. First, we identify, characterize, and categorize the major classes of disputes – e.g., those affecting import prot Read More

As an internationally standardized product nomenclature, the Harmonized System (HS) is used by WTO Members in their schedules of concessions and in the definitions of product coverage for a number of WTO agreements. The Harmonized System is normally amended by the World Customs Organization every four to six years. These amendments pose considerable challenges for the WTO and its Members. On the one hand, Read More

The paper discusses the efforts deployed by various players, mainly multilateral financial institutions, regional development banks, export credit agencies, to mobilize greater flows of trade finance for developing countries, with a view to help them integrate in world trade. As an institution geared towards the balanced expansion of world trade, the WTO is in the business of making trade possible. Its various functions include Read More

Economic theory has made considerable progress in explaining why sovereign countries cooperate in trade. Central to most theories of trade cooperation are issues of self-enforcement: The threat of reprisal by an aggrieved party maintains the initial balance of concessions and prevents opportunism. However, economic scholarship has been less coherent in explaining why countries choose to settle and enforce their trad Read More

This paper examines the impact of telecommunications liberalization in Africa on both sectoral performance and economic growth. Besides unilateral measures, we account for WTO commitments fostering the credibility of reforms. Actual regulatory quality plays a major role in bringing down prices and in improving access to telecommunication services in Africa. Competition, notably in the mobile telephony segment, als Read More

The General Agreement on Trade in Services (known as the GATS) is an important new element in the international framework that affects the regulation of every WTO Member's financial sector. However, except for a limited number of country-specific case studies, no attempt has been made to compare WTO commitments to open the domestic banking sector to foreign banks with actual regulatory practice in a systema Read More

This 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 s Read More

This 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 severa Read More

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 Read More

Economists 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 concer Read More

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 ( Read More
