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...

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 surveys the state of knowledge about the trade-related environmental consequences of a country's development strategy along three channels: (i) direct trade-environment linkages (overexploitation of natural resources and trade-related transport costs); (ii)'virtual trade'in emissions...
