Globalization and Trade Flows
Publication Date: junio 2010Más MenosThe trade collapse that followed the recent financial crisis has led to a renewed interest on the measurement issues affecting international merchandise trade statistics in the new globalized economy. The international fragmentation of industrial production blurs the concept of country of origin and calls for the production of new statistics on the domestic content of exports, with a view of estimating trade in value added. Alongside, the international statistical community has revised in 2010 the concepts and definitions on both, international merchandise trade and trade in services statistics. This paper discusses the various issues related to the concepts of "goods for processing" and "intra firm trade" in trade statistics, and provides an overview of the method of analysing the impact of the fragmentation of production in international value chains.

Endowments, Power, and Democracy
Publication Date: junio 2010Más MenosIn 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 argument suggesting how levels of democracy and factor endowments are associated with more commitments. The empirical analysis supports these propositions, and also suggests that relative size, as well as regulatory capacity, are positively linked to GATS commitments.

More Stringent BITs, Less Ambiguous Effects on FDI? Not a Bit!
Publication Date: mayo 2010Más MenosWe focus on investor-state dispute settlement provisions contained in various, though far from all, bilateral investment treaties as a possible determinant of BIT-related effects on bilateral FDI flows. Our estimation results prove to be sensitive to the specification of these provisions as well as the inclusion of transition countries in the sample. Stricter dispute settlement provisions do not necessarily result in higher FDI inflows so that the effectiveness of BITs as a credible commitment device remains elusive.

International Regulation and Treatment of Trade Finance
Publication Date: febrero 2010Más MenosThe 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 multilateral agencies. The paper does not deal with the specific issue of regulation of official insured-export credit, under the OECD Arrangement, which is a specific matter left out of this analysis. Traditionally, trade finance has received preferred treatment on the part of national and international regulators, as well as by international financial agencies in the treatment of trade finance claims, on grounds that trade finance was one of the safest, most collateralized, and selfliquidating forms of trade finance. Preferred treatment of trade finance also reflects the systemic importance of trade, as in sovereign or private defaults a priority is to "treat" expeditiously trade lines of credits to allow for such credit to be restored and trade to flow again. It is not only a matter of urgency for essential imports to be financed, but also a pre-condition for economic recovery, as the resumption of trade is necessary for ailing countries to restore balance of payments equilibrium. The relatively favourable treatment received by trade finance was reflected in the moderate rate of capitalization for cross-border trade credit in the form of letters of credit and similar securitized instruments under the Basel I regulatory framework, put in place in the late 1980s and early 1990s. However, as the banking and regulatory communities moved towards internal-rating based and risk-weighted assets systems under the successor Basel II framework, a number of complaints emerged with respect to the treatment of trade credit – particularly in periods of crisis. Issues of pro-cyclicality, maturity structure and country risk have been discussed at some length in various fora, including in the WTO at the initiative of Members. Part of the issue was that Basel II regulation was designed and implemented in a manner that, in periods of banking retrenchment, seemed to have affected the supply of trade credit more than other potentially more risky forms of lending. With the collapse of trade in late 2008 and early 2009, the regulatory treatment of trade credit under Basel II clearly became an issue and was discussed by professional banking organizations, regulators and international financial institutions. A sentence made its headway into the communiqué of G-20 Leaders in London in April 2009, calling upon regulators to exercise some flexibility in the application of Basel II rules, in support of trade finance. As the issue of removing the obstacles to the supply of trade finance spread became part of the public debate, discussions with respect to the regulatory treatment of trade finance in the context of the making of "Basel III" rules are now raising political attention. Part of the underlying problem regarding the design of regulation of trade finance is that banking regulators may not have enough understanding of the way that trade and trade finance operate in practice. In turn, the banking community has made insufficient progress in explaining these issues to regulators and in providing evidence about the high level of safety and soundness of their activity, in collecting statistical information and even in defining clearly what comprises trade finance. This paper aims at clarifying such issues. The WTO, in its role as an "honest broker", is trying to help the parties concerned, and has been asked from time to time to act as a go-between between the two communities, in order to clarify issues. Section 1 looks at the overall Basel framework and its evolution over time, with particular emphasis on the regulation of trade finance. Section 2 looks at issues raised in the WTO context by the trading and trade finance communities, be it by WTO Members or by experts, and how this has helped to clarify some of the disputed issues. Section 3 raises a number of questions which need clarification from the trade finance community for regulators to be able to better capture the reality of trade finance operations, and allow them to regulate with full understanding of its implications.

International Supply Chains and Trade Elasticity in Times of Global Crisis
Publication Date: febrero 2010Más MenosThe paper investigates the role of global supply chains in explaining the trade collapse of 2008-2009 and the long-term variations observed in trade elasticity. Building on the empirical results obtained from a subset of input-output matrices and the exploratory analysis of a large and diversified sample of countries, a formal model is specified to measure the respective short-term and long-term dynamics of trade elasticity. The model is then used to formally probe the role of vertical integration in explaining changes in trade elasticity. Aggregated results on long-term trade elasticity tend to support the hypothesis that world economy has undertaken in the late 1980s a “traverse” between two underlying economic models. During this transition, the expansion of international supply chains determined an apparent increase in trade elasticity. Two supply chains related effects (the composition and the bullwhip effects) explain also the overshooting of trade elasticity that occurred during the 2008-2009 trade collapse. But vertical specialization is unable to explain the heterogeneity observed on a country and sectoral level, indicating that other contributive factors may also have been at work to explain the diversity of the observed results.

What Constrains Africa's Exports?
Publication Date: febrero 2010Más MenosWe 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 contrast, longer delays in the other areas have a far smaller impact on trade. We control for the possibility that greater trade leads to shorter delays in three ways. First, we examine the effect of trade times on exports of new products. Second, we evaluate the effect of delays in a transit country on the exports of landlocked countries. Third, we examine whether delays affect time-sensitive goods relatively more. We show that large transit delays are relatively more harmful because of high within-country variation.

International Rules for Trade in Natural Resources
Publication Date: enero 2010Más MenosThis paper investigates the scope for international rules to address market failures in trade in natural resources and the associated international transactions of prospecting and investment in resource exploitation. We argue that several market failures are likely to have substantial costs. However, due to the distinctive features of natural resources, the market failures are particular to them. The ad hoc approaches which have attempted to address them to date leave scope for a more systematic and comprehensive approach by the WTO, but the distinctive features of natural resources imply that this could not simply be an application of the rules appropriate for other forms of trade.

The Relation between International Trade and Freshwater Scarcity
Publication Date: enero 2010Más MenosIt 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 volume of water that has been used to produce a commodity and that is thus virtually embedded in it. Knowledge about the virtual-water flows entering and leaving a country can cast a completely new light on the actual water scarcity of a country. For example, Jordan imports about 5 to 7 billion m3 of virtual water per year, which is in sharp contrast with the 1 billion m3 of water withdrawn annually from domestic water sources. This means that people in Jordan apparently survive owing to the import of water-intensive commodities from elsewhere, for example the USA.

Trade and Deforestation
Publication Date: enero 2010Más MenosForest plays a significant role in the overall balance of carbon in the atmosphere. Forest carbon sequestration can potentially reduce the accumulation of greenhouse gases in the atmosphere. However, when deforestation takes place, carbon is released to the atmosphere again. Globally, it has been estimated that about 11% to 39% of all carbon emissions from human origin come from the forest sector (Hao et al. 1990). Regarding global warming, the balance between forest conservation and deforestation can change forest sector activities from a solution to a problem and vice versa.

Trade and Fisheries
Publication Date: enero 2010Más MenosIn 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 issues in relation to seafood and trade, including sections on managing the global commons and domestic trends in management. In the final section, we discuss specific issues that are germane to the WTO and its rules.

Oil Price Volatility
Publication Date: enero 2010Más MenosIn recent years, our understanding of the nature of energy price shocks and their effects on the economy has evolved dramatically. Only a few years ago, the prevailing view in the literature was that at least the major crude oil prices increases were exogenous with respect to the OECD economies and that these increases were caused by oil supply disruptions triggered by political disturbances in the Middle East. This view has little empirical support. Likewise, the popular notion that OPEC constitutes a cartel that controls the price of oil has not held up to scrutiny. At the same time, there has been increasing recognition of the importance of shifts in the demand for oil. Recent research has provided robust evidence that oil demand shocks played a central role in all major oil price shock episodes since the 1970s.

Trade in Mineral Resources
Publication Date: enero 2010Más MenosThis 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 the five topics requested by the World Trade Organization: theoretical and empirical literature on international trade in minerals; trade impacts of mineral abundance and the resource curse; the political economy of mineral trade in resource-abundant states; non-economic considerations associated with strategic mineral resources; and the impact of domestic market structure and regulation on production and trade in minerals.

Restoring Trade Finance During a Period of Financial Crisis
Publication Date: diciembre 2009Más MenosThe paper discusses the efforts deployed in 2008 and 2009 by various players, Governments, multilateral financial institutions, regional development banks, export credit agencies, to mobilize sufficient flows of trade finance to off-set some of the “pull-back” by commercial institutions in the period of acute crisis that has characterized the financial sector in the past two years. Given that 80 to 90% of trade transactions involve some form of credit, insurance or guarantee, one can reasonably say that supply-side driven shortages of trade finance have a potential to inflict further damages to international trade. As an institution geared towards the balanced expansion of world trade, the WTO had been concerned with occurrences of market tightening throughout this period. While a number of public-institutions mobilized financial resources for trade finance in the fall of 2008, this has not been enough to bridge the gap between supply and demand of trade finance worldwide. As the market situation continued to deteriorate in the first quarter of 2009, G-20 leaders in London (April 2009) adopted a wider package for injecting additional liquidity and bringing public guarantees in support of $250 billion of trade transactions in 2009 and 2010. Ahead of the Pittsburgh Meetings, experts reported that more than the targeted amount had been mobilized. In the meantime, through the summer and the fall of 2009, the market situation seemed to have eased – although in many countries, access to trade finance by the smaller traders had become either significantly more expensive or had simply disappeared. One can expect the trade finance market to have its up and downs for some time, because lending for trade is a function of the general lending situation of commercial banks. The paper discusses longer-term initiatives aimed at improving the resilience of the trade finance market to short-term and longer-term shocks.

Trade in Healthcare and Health Insurance Services
Publication Date: diciembre 2009Más MenosThe 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 possibilities. While most participants elected not to undertake bindings on healthcare services at the end of the Uruguay Round, nor to make offers in the ongoing negotiations, insurance services have been among the most frequently committed sectors. If there is a common denominator, regardless of the Members concerned (except for recently acceded countries), it is the existence of a lot of 'water' between existing commitments and more open conditions of actual access in many sectors. This may also explain, in part, why there have been very few trade disputes under the GATS to date - far fewer than under the GATT in merchandise trade. Also, governments appear to be generally hesitant in politically and socially sensitive areas to take action in the WTO. There are indications, however, that the same 'players' have acted differently in other policy contexts. For example, it appears that under recent preferential trade agreements (PTAs) the European Communities has been even more cautious in committing on hospital services and protecting scope for (discriminatory) subsidies than under the GATS. Yet, this is not necessarily true for the obligations assumed by many countries, including individual EC Member States, under bilateral investment treaties (BITs). These treaties overlap with the GATS, as far as commercial presence is concerned, and may be used by aggrieved investors to challenge policy restrictions in host countries. However, though frequently invoked, BITs do not meet the same standards, in terms of transparency, open (consensual) rulemaking and legal certainty, as commitments under the GATS.

Market Shares in the Post-Uruguay Round Era
Publication Date: diciembre 2009Más Menosto identify underlying sources of growth or decline. A key feature is that the unit of analysis (e.g. a city, a region or a country) exists within a broader frame of reference that strongly influences it (e.g. a national productive system or the world economy). It is based on the principle that total change can be disaggregated into contributing factors and any change that can not be accounted for by these factors can be interpreted as the "local contribution" to that total change. This method has been subject to many refinements. Because the objectives of this paper are both didactic and analytic, traditional Shift-Share Analysis is applied to international trade. It uses the "constant market share" assumption by decomposing the growth of exports into four separate components: a global component (GLOBO) indicating changes due to overall growth of world trade, a geographical component (GEO) indicating changes due to the country's distribution of trading partners, a product composition component (COMPO) indicating growth due to the mix of products exported, and a residual term (the "local" contribution) indicating changes in competitiveness, or performance (PERFO). The first 3 components, GLOBO, COMPO and GEO all relate to the "expected change in trade" should trade change proportionally. The fourth and residual component, PERFO, refers to that part of the change in trade that "shifts away" from expected proportional changes, hence the term "Shift-Share Analysis". This paper will analyse a change or "shift" in shares in trade (particularly exports) of different economies. By focusing on selected time periods and using the PERFO indicator, the method will show what industries shift away from the expected change in trade, which economies have experienced such shifts in their industries, and to which regions.

The Value of Domestic Subsidy Rules in Trade Agreements
Publication Date: noviembre 2009Más MenosThis paper investigates the efficient design of rules on domestic subsidies in a trade agreement. A clear trade-off emerges from the economic literature. Weak rules may lead Member governments to inefficiently use domestic subsidies for redistributive purposes or to lower market access granted to trading partners once tariffs are bound. On the other hand, excessive rigidity may inhibit tariff negotiations or induce governments to set inefficiently high tariffs, as strict regulations would reduce policy makers' ability to use subsidies to offset domestic market distortions. Efficient subsidy rules are, therefore, the ones that strike the right balance between policy flexibility and rigidity. This economic approach provides a framework to interpret the provisions on domestic subsidies in the WTO.

The WTO
Publication Date: noviembre 2009Más MenosWe 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 the GATT/WTO, and we identify key unresolved issues.

The Economics of Trade Agreements in the Linear Cournot Delocation Model
Publication Date: noviembre 2009Más MenosExisting theories of trade agreements suggest that GATT/WTO efforts to reign in export subsidies represent an inefficient victory for exporting governments that comes at the expense of importing governments. Building from the Cournot delocation model first introduced by Venables (1985), we demonstrate that it is possible to develop a formal treatment of export subsidies in trade agreements in which a more benign interpretation of efforts to restrain export subsidies emerges. And we suggest that the gradual tightening of restraints on export subsidies that has occurred in the GATT/WTO may be interpreted as deriving naturally from the gradual reduction in import barriers that member countries have negotiated. Together with existing theories, the Cournot delocation model may help to provide a more nuanced and complete understanding of the treatment of export subsidies in trade agreements.

Trade Skirmishes and Safeguards
Publication Date: noviembre 2009Más MenosI 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 under the Agreement on Safeguards as an attempt to reduce efficiency-reducing trade skirmishes. The DSP is interpreted as an impartial arbitrator that announces its opinion about the state of the world when a dispute arises among member countries. I demonstrate that the reforms in the GATT escape clause should be bundled with the introduction of the DSP, in order to maintain the incentive-compatibility of trade agreements. The model implies that trade agreements under the WTO lead to fewer trade skirmishes but this effect does not necessarily result in higher payoffs to the governments. The model also implies that the introduction of the WTO court, which has no enforcement power, can in fact improve the self-enforceability of trade agreements.
