This study examines the effect of NAFTA, an instance of North-South trade liberalization, on returns to skill in Mexico. Mexico is abundant in low-skill workers relative to the US and Canada, and so, by the Hecksher-Ohlin-Samuelson trade model, NAFTA ought to have raised the relative earnings of...

How does factor accumulation affect the pattern of international specialization and returns to capital? We provide a new integrated treatment to this question using a panel of 44 developing and developed countries over the period 1976-2000. We confirm the Heckscher-Ohlin prediction that, with...

Recent research has documented a U-shaped industrial concentration curve over an economy's development path. How far can neoclassical trade theory take us in explaining this pattern? We estimate the production side of the Heckscher-Ohlin model using industry data on 44 developed and developing...

We discuss the effects of offshoring on the labor market in a matching model with endogenous adjustment of educational skills. We carry out a comparative statics analysis and show that offshoring leads to a restructuring of the economy through skill-biased technical change (SBTC) where overall...

The COVID-19 pandemic has disrupted trade and global value chains. Small open economies such as Portugal are particularly vulnerable. In this paper we consider the impact of the pandemic on the country's exports, arguing that an export-led recovery is possible. The challenge is to identify...

I study individual location, education and work decisions in a dynamic life-cycle model in a developing country. I estimate the model exploiting panel data on migrants and stayers in Burkina Faso, and cross-sectional data on permanent emigrants. Individuals self-select into migration and...

We present a dynamic life-cycle model of women's labor supply, marriage, and fertility choices that explicitly incorporates mental and physical health. Correlated mental and physical health production functions are simultaneously estimated, including the endogenous decisions to seek...

This paper integrates institutionally determined wage rigidities into an otherwise standard Heckscher-Ohlin model of international trade. It accounts for differences in individual productivities and their implications for individual wage incomes and demand for education. Although preserving the...
