National Environmental Policies and Multilateral Trade Rules
Publication Date: January 2004More LessThis 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: December 2003More LessThis 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: August 2003More LessThis 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: August 2003More LessThis 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: August 2003More LessThis 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: April 2002More LessThe 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: February 2002More LessThis 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: November 2001More LessNon-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: August 2001More LessThe 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: August 2001More LessThe 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.

International Trade and the Position of European Low-Skilled Labour
Publication Date: November 2000More LessThis paper presents a discussion of the potential channels through which international trade affects the position of low skilled workers in the European Union. After an analysis of the European Union's trade flows showing the predominant role of intra-industry trade with other industrialised countries, the discussion focuses on the potential effects of intra-industry trade on low skilled labour. Particular attention is paid to possible interactions between trade and technological change and to the possible effects of trade on the price elasticity of labour. The paper also discusses how trade may affect incentives to invest in skills and thus a country's potential to alter the skill structure of its working force.

Whether and When to Liberalize Capital Account and Financial Services
Publication Date: November 1999More LessDiscussions about international capital movements raise extremely important and controversial questions. Why should countries open up their capital accounts, especially considering that unrestricted international capital movement is a relatively new phenomenon? For example, many OECD countries have not eliminated their foreign exchange restrictions only until the 1980's. If the answer is unequivocally affirmative, does it matter how fast should countries do so? Should they wait until "all essential pieces" of the policy package are in place before they eliminate all restrictions? How are international capital movements related to domestic financial sectors? Is there a difference between opening to competition an industry such as car manufacturing as compared to the banking sector? Should the opening of the banking sector be governed by different rules? Rules about foreign exchange restrictions are already in place in the IMF Articles. Until recently, the IMF Articles only called for the elimination of foreign exchange restrictions on the current account. The ongoing discussion and the controversy about globalization that calls for the capital account liberalization introduces, therefore, a relatively new element into the whole discussion. These questions have also implications for the World Trade Organization. It is well known, that the Uruguay Round Agreements have already provided a coverage for a number of aspects that are directly related to foreign investment. Rules established elsewhere such as in the context of changes to the IMF Articles will obviously have an important bearing for the implementation of rules agreed in the Uruguay Round. This raises a variety of other questions in the mind of some observers. Who should decide about the rules on capital account liberalization? What rules? IMF? What is the role of the WTO? How does one link the two? All of the questions raised above are clearly extremely important and most of them are discussed in the following paper by John Williamson. Mr. Williamson's presentation is based on his lecture and discussion which was delivered on 17 June 1999 at the WTO. The actual text that follows is a transcript of that lecture.

A Quantitative Assessment of Electronic Commerce
Publication Date: September 1999More LessThis paper tries to assess quantitatively the role of electronic commerce in economic activity and in trade and tariff revenue collection. The share of value added that potentially lends itself to electronic trade represents around 30 percent of GDP, most importantly distribution, finance and business services. Electronic commerce is also likely to boost trade in many services sectors significantly. Despite the growing importance of electronic commerce for economic activity and trade, tariff revenue loss from electronic commerce is likely to be minimal. Trade in potentially digitizable media goods which currently faces a tariff in some countries represents less than one percent of total world trade. The revenue collected on these products amounts to less than one percent of total tariff revenue in most countries. Even if some of this trade moved “online”, tariff revenue loss would be only a very small share of tariff revenue.

The EU Model and Turkey
Publication Date: January 1999More LessThe customs union between the European Union (EU) and Turkey, which entered into force in January 1996, extended and deepened the Association Agreement, signed in 1964 and which foreshadows full EU membership for Turkey. In a number of areas, the new relationship goes beyond the minimum requirements for a customs union: Turkey is also having to implement a number of measures which are part of the acquis communautaire, similar to those applicable within the EU. This paper addresses the question whether this adoption of the EU model is beneficial to Turkey and third countries. The importance of this issue is the spreads of this model through the extension of the EU itself and the building of an increasing web of partnerships between the EU and other countries in Central and Eastern Europe as well as Mediterranean countries. Moreover, other regions are looking at the EU model as a way in which to deepen their own preferential trading arrangements.

Financial Services Trade, Capital Flows, and Financial Stability
Publication Date: November 1998More LessThis study argues that trade policies regarding financial services are an important—but often neglected—determinant of capital flows and financial sector stability. Financial services trade liberalisation which promotes the use of a broad spectrum of financial instruments and allows the presence of foreign financial institutions whilst not unduly restricting their business practices, results in less distorted and less volatile capital flows, and promotes financial sector stability. The study finds significant evidence in favour of this claim through an empirical analysis of GATS commitments in 27 emerging markets. For example, countries which experienced financial crisis during 1991-97 show a combined indicator of financial services trade restrictiveness three times as high (= less favourable for financial stability) as countries without a crisis. The study' s findings have two important policy implications. Firstly, liberalising international trade in financial services can be a market-based means to improve the "quality" of capital flows and to strengthen financial systems. This would complement other policies, including financial regulation. Secondly, even in countries where the financial system is weak, and where immediate, full-fledged financial sector liberalisation is not advisable, certain types of financial services trade could be liberalised, as such trade strengthens the financial system without provoking destabilising capital flows.

A Simple Trade Policy Perspective on Capital Controls
Publication Date: October 1998More LessThis note discusses capital controls using insights from the trade policy literature. It highlights some key issues that have been neglected in the current international debate on capital controls. Capital is tradable in the same way as many goods and services are. As a result, much of the analysis pertaining to trade and trade policy in goods and services applies with equal force to capital movements. Free trade is typically the best trade policy, no matter whether it is trade in goods, services or capital. But if investor behaviour and the prevailing policy environment are not conducive to immediate free trade, the choice of instrument for controlling capital flows becomes important. Tariffs and other price-related restrictions are preferable to quantitative restrictions or prohibitions because: (i) they cause less rent seeking, and (ii) they do not insulate the domestic market from price changes and innovations in international markets.

Preferential and Non-Preferential Trade Flows in World Trade
Publication Date: September 1998More LessThis paper quantifies the extent of preferential trade as a share of total world trade in different regions of the world and for two periods. Results show that: i) preferential trade represented 40% of world trade in the period 1988-1992 and it slightly increased to 42% during the period 1993-1997; ii) during the second period, agricultural products generally benefited more from the existence of preferential trade agreements than industrial products (maybe due to GATT-exemption); iii) the regional distribution of preferential trade is relatively uneven with a significant share of preferential trade in Western Europe (around 70 per cent), relatively low values in the Western Hemisphere (around 25 per cent), very low shares in Asia and Oceania (around 4 per cent) and average values in the rest-of-the-world (Eastern Europe and Africa); iv) the largest increase in shares of preferential trade between the two periods has occurred in the Western Hemisphere and in Eastern-Europe and Africa; v) at the country level there is an inverted-u-shape relationship between the share of preferential trade and the size and GDP per capita of individual countries; vi) countries which are highly open to trade tend to have a larger share of preferential trade on total trade in the period 1993-1997, suggesting that preferential and non-preferential trade can be seen as complements.

Does Globalization Cause a Higher Concentration of International Trade and Investment Flows?
Publication Date: August 1998More LessIt has sometimes been argued that "globalization" benefits only a small number of countries, and that this leads to greater marginalization of excluded countries. This paper argues that globalization is not necessarily biased towards greater concentration in international trade and investment flows. Marginalization is more likely to be explained by domestic policies in relatively closed countries. The paper shows that among relatively open economies, the concentration of international trade and investment flows has declined over the last two decades, whereas the opposite is true among relatively closed economies. Thus, marginalization is not intrinsic to globalization. Key Words: Globalization, international trade and investment flows concentration.

Exchange Rate Regimes and the Stability of Trade Policy in Transition Economies
Publication Date: July 1998More LessThis paper examines the interplay between exchange rate regimes and policies and commercial policy in six transition economies. In all these economies the rate of protection afforded domestic industry by the exchange rate has been eroded by high rates of inflation and insufficient growth in productivity. As a result, there has been pressure on governments to increase trade barriers and each country examined has had recourse to various means of restricting imports. We argue that more flexible management of the nominal exchange rate would be a preferable way of dealing with the real appreciation of these countries’ currencies.

Fiscal Policy Cycles and the Public Expenditure in Developing Countries
Publication Date: June 1998More LessThe 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.
