The Armington substitution elasticity is a key parameter for trade-policy analysis. We estimate short- and long-run Armington elasticities for 309 manufacturing industries at the four-digit Standard Industrial Classification (SIC) level over the period 1989-1995. Our estimation results offer a...

This paper focuses on the U.S. tariff preference afforded to Mexico vis-à-vis non-NAFTA trading partners, and allows us to evaluate the impact of NAFTA in a manner consistent with the idea behind a preferential trading agreement. The estimation technique exploits the time-varying dimension of...

Total U.S. trade with NAFTA partners has increased 78 percent in real terms since 1993U.S.-Mexico trade alone is up 141 percentcompared to a 43 percent increase in U.S. trade with the rest of the world. In this article we compare the nature of U.S. trade growth with Canada and Mexico to growth...

Applied partial and general equilibrium models used to examine trade policy are almost universally sensitive to trade elasticities. Indeed, the Armington elasticity, the degree of substitution between domestic and imported goods, is a key behavioral parameter that drives the quantitative, and...

A key parameter that determines the distributional impacts of a policy shift in general equilibrium models is the elasticity of substitution between capital and labor. Despite the importance of this parameter in applied modeling, its identification continues to pose a challenge. Given the...
