This paper examines the theory underpinning the design of optimal tariffs in a developing economy, and the experience of implementation of tariff reforms. A central issue is whether and when a case can be made for a uniform tariff structure. While theory advocates a differentiated tariff structure (except under a balance of payments objective), political economy considerations, inadequate information, and administrative convenience point to a minimally differentiated tariff structure. The experience of reform indicates that tariff structures are mainly influenced by income distribution and protection objectives. The ability to successfully reduce tariffs depends on measures taken to alleviate fiscal and balance of payments constraints.

New horizons are opening for Africa, with a growing number of Chinese andIndian businesses fostering its integration into advanced markets. However,significant imbalances will have to be addressed on both sides of the equation to support long-term growth.

The paper contributes to the discussion about the revenue implications of trade reform by assessing the approximate fiscal revenue impact of different liberalization formulae under consideration in multilateral trade negotiations for a group of low- and middle-income countries. The study applies a linear optimization framework to data for bound tariffs, applied tariffs, and imports at the HS-6 digit level for 58 developing countries, and simulates results for different sets of import demand elasticities and developing country \"flexibilities.\" While only a small number of countries face a significant impact, results point toward the need for complementary fiscal measures in the countries most affected by revenue loss.

This paper assesses the effects of reducing tariffs under the Doha Round on market access for developing countries. It shows that for many developing countries, actual preferential access is less generous than it appears because of low product coverage or complex rules of origin. Thus lowering tariffs under the multilateral system is likely to lead to a net increase in market access for many developing countries, with gains in market access offsetting losses from preference erosion. Furthermore, comparing various tariff-cutting proposals, the research shows that the largest gains in market access are generated by higher tariff cuts in agriculture.

This paper studies the structure and evolution of trade protection in the Middle East and North African (MENA) countries in the 1990s. MENA countries use tariffs and nontariff barriers, and tariff dispersion and nontariff barriers, as substitute protection measures. Tariff levels and tariff dispersion are complements. Excluding Tunisia, the cross-country correlation between tariff and nontariff barriers is -0.46. The correlation between tariff dispersion and nontariff barriers is -0.8. The paper also develops an overall index of trade protection and finds that tariff levels, their dispersion, and nontariff barriers account for 60 percent, 10 percent, and 30 percent of overall protection, respectively.

Ukraine's Trade Policy identifies the key drivers of Ukraine's recent trade performance, assesses current trade policies, and proposes recommendations to strengthen the Ukraine’s trade integration strategy. It also identifies core bottlenecks in the ongoing integration processes, including global and regional integration. The study concludes that the main obstacles to furthering Ukraine’s trade integration are domestic, and relate to deficiencies in the business environment. Problems in customs administration, standardization, and administrative barriers for new entry require immediate attention. The report highlights specific policy issues that hamper WTO accession, such as trade legislation, protection of intellectual property rights, government support for specific industries, and export restrictions. It also recommends improvements in the structure of Ukraine’s import tariffs, reform of both the regime of free economic zones and mechanism of VAT refund, and investment in a major upgrade of government capacity for investment and export promotion. The report also draws attention to the importance of the post-WTO accession agenda for Ukraine. To take advantage of WTO membership, the Government will need to undertake significant institutional reforms to implement WTO regulatory rules in ways that facilitate integration into the world economy and provide benefits to private sector participants.

The World Bank's 'World Trade Indicators' (WTI) database on the CD-ROM in this volume provides more than 300 performance indicators measuring at-the-border and behind-the-border country trade policy, institutions, and outcomes from 1995 to 2007. The database allows each country to be ranked by any policy or performance dimension relative to others. Trade-at-a-Glance tables for the 210 countries in the database facilitate comparisons among countries in key areas. Complementing the rich database are Trade Briefs for 142 developing countries summarizing insights from the data and the main findings of analytical work conducted by the Word Bank, the International Monetary Fund, and the World Trade Organization for individual countries.The companion volume to the 'World Trade Indicators 2008' highlights the main patterns in policy and performance revealed by the database grouping countries by region or income. The 20 best and 20 worst country rankings for a number of indicators are shown. For country policy makers, trade negotiators, and advisors, this volume provides the rich context within which to interpret a single country's standing on various dimensions. Business people will gain new insights about the countries in which they and their competitors operate. Trade researchers will find tantalizing country stories on trade policy and institutional dimensions and trade outcomes.Country performance is benchmarked in five key areas: ? Border protection, such as tariffs and nontariff barriers on imports of goods and services ? Market access barriers in the rest of the world to exports of goods ? Overall business and institutional environment ? Trade facilitation ? Trade outcomes, such as trade growth, integration, and diversification.

This paper analyzes particular areas of tax policy that have concerned the Colombian authorities during the 1990s, while comprising a comprehensive approach to tax reform over time. It is intended to allow the reader to view in technical detail the type of analysis conducted in a representative tax reform study carried out by the IMF

This paper reviews the extent to which the Fund's trade policy advice to the Baltic countries, Russia and other countries of the Former Soviet Union has been implemented. It broadly traces the evolution of trade policies, emphasizing the period from mid-1993 through end-1995, attempting to identify some of the factors affecting uneven progress in trade reform. Based on insights from the public choice literature on endogenous policy theory, the paper makes recommendations for refining Fund advice with a view to facilitating future progress on the trade-policy front.
