This paper uses detailed data on bound and applied tariffs to assess the consequences of the World Trade Organization’s December 2008 Modalities for tariffs levied and faced by developing countries, and the welfare implications of these reforms. The authors find that the tiered formula for...

Traditional weighted-average measures of trade distortions are widely used in analyzing global and regional reforms, despite well-known deficiencies. This paper develops and applies optimal aggregators for the real-world case of multiple countries and commodities with much more detailed...

This paper addresses three questions relating to the very extensive use of the GTAP global trade protection database: Are there additional price-distorting policy instruments worthy of inclusion in the base year? What is the appropriate counterfactual set of price distortions in the year of...

To analyze the effects of prospective policy changes, sectoral and economy-wide modelers need to begin with baseline estimates of policy induced price distortions. Global trade modelers mostly use the Global Trade Analysis Project (GTAP) protection database, which currently relies heavily on...

This paper provides new estimates of the global gains from multilateral trade reform and their distribution among developing countries in the presence of trade preferences. Particular attention is given to agriculture, as farmers constitute the poorest households in developing countries but the...

This study is part of a global research project seeking to understand the changing scope and impact of the policy bias against agriculture and the reasons behind agricultural policy reforms in Africa, Europe's transition economies, Latin America and the Caribbean, and Asia. One purpose of the...
