In a series of recent papers, Neary and others have established the importance of trade in factor services, especially capital, in determining the welfare effects of import restrictions by tariffs, QRs, and VERs. In the absence of induced terms-of-trade changes and rental rate effects, Neary...

Madagascar's weak administrative system and complex tax structure (with many exemptions) have led to tax evasion and smuggling. The authors compare Madagascar's fiscal system with that of other low-income countries, noting its greater reliance on distortionary taxes. Using a 10-sector model and...

This paper sets out to test the robustness of Balassa's recommendation of neutral incentives to domestic and export sales in a setting where some sectors have domestic market power. This paper shows analytically that the welfare effects of trade policy are more complex than they are in a setting...

Drawing on evidence about industrial organization and market structure, the authors develop a computable general equilibrium model in selected industrial sectors with increasing returns to scale. They use this model to estimate the welfare gains Korea would realize from abolishing the import...

Trade policies can promote aggregate efficiency, but the ensuing structural adjustments generally create both winners and losers. From an incomes perspective, trade liberalization can raise gross domestic product per capita, but rates of emergence from poverty depend on individual household...

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 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...

This study analyzes the long-term impacts of large-scale expansion of biofuels on land-use change, food supply and prices, and the overall economy in various countries or regions using a global computable general equilibrium model, augmented by a land-use module and detailed representation of...
