In recent decades, growth of overall world trade has been driven in large part by the rapid growth of trade in intermediate inputs. Much of this input trade involves multinational firms locating input processing in their foreign affiliates, thereby creating global vertical production networks....

In this paper, we document the importance of high-skilled immigration for U.S. employment in STEM fields. To begin, we review patterns of U.S. employment in STEM occupations among workers with at least a college degree. These patterns mirror the cycle of boom and bust in the U.S. technology...

Recent theoretical work tends to characterize multinational enterprises as arising through either horizontal or vertical foreign direct investment (FDI). Empirical research tends to find stronger support for the former than for the latter. In this paper, we use recent, detailed data on U.S....

In the early 1990s Israel experienced a large and concentrated surge of immigration from the former Soviet Union. Most Russian immigrants had high education levels relative to the average Israeli. Despite the size and skill mix of the immigration shock, existing research has found little...

Recent literature on the labor-market effects of U.S. immigration tends to find little correlation between regional immigrant inflows and changes in relative regional wages. In this paper we examine whether immigration, or endowment shocks more generally, altered U.S. regional output mixes as...

In recent years many economists have analyzed whether international trade has contributed to rising U.S. wage inequality by changing relative product prices. In this paper I survey the findings of nine product-price' studies which together demonstrate how the methodology of product-price studies...

In this paper I analyze whether international trade contributes to per capita income convergence across countries. The analysis focuses on four important post-1945 multilateral trade liberalizations. To identify trade's effect on income dispersion, in each case I use a difference-in-differences'...

In this paper I try to determine whether international trade has been increasing the own-price elasticity of demand for U.S. labor in recent years. The empirial work yields three main results. First, from 1960 through 1990 demand for U.S. production labor became more elastic in manufacturing...

The recent literature on cross-country convergence of per capita income has largely ignored international trade. The reason might be perspective. Most convergence papers frame the analysis in a `Solow world' in which countries exist independent of one another. But most international trade...

In antebellum America an extensive network of canals and railroads was constructed which slashed transportation costs across regions. This 'transportation revolution' presents an interesting case study of the factor-price convergence (FPC) theorem. In this paper I look for integration of...
