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...

According to recent UN projections more than 50 percent of the growth in world population over the next half century will be due to population growth in Africa. Given this, any policy that influences African demography will have a significant impact on the world distribution of income. In this...

This paper explores the quantitative consequences of transatlantic trade liberalization envisioned in a Transatlantic Trade and Investment Partnership (TTIP) between the United States and the European Union. Our key innovation is to develop a new quantitative spatial trade model and to use an...

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...

This paper examines the welfare implications associated with different degrees of diversity or similarity between migrants and natives under both migration and trade. We use a general equilibrium model of migration, human capital and social capital and find that there are three equilibrium...

In a two-sector, general-equilibrium model with labor-market search frictions, we find that wage increases and sectoral unemployment decreases upon offshoring in the presence of perfect intersectoral labor mobility. If, as a result, labor moves to the sector with the lower (or equal) vacancy...

This paper highlights that the immigrants' effect on trade is not identical across all types of immigrants but it varies with the immigrants' occupation. Using a sample of 63 U.S. trading partners which are also big immigrant sending countries over the years 1991-2000, this paper finds that the...

This paper examines the role of immigrant networks on trade, particularly through the demand effect. First, we examine the effect of immigration on trade when the immigrants consume more of the goods that are abundant in their home country than the natives in a standard Heckscher-Ohlin model and...

We use a version of the Meade model to consider the effects of interdependent import tariffs in the presence illegal immigration. First, we consider the small union case and derive the Nash tariff equilibrium for two potential members of a Preferential Trade Agreement (PTA). We analyze...

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...
