It is now well known that exogenous immigration shocks tend to have benign effects on native employment outcomes, thanks to various secondary adjustment processes made possible by flexible markets. One adjustment process that has received scant attention is that immigrants, as consumers of the goods they help produce, contribute to their own demand. We examine the effects of an immigration shock on labor demand by testing a general equilibrium model in which imperfectly substitutable native and immigrant workers spend their wages on a locally produced good. The shock induces three responses: (i) a substitution of immigrants for natives; (ii) out-migration; and (iii) stimulation of labor demand. According to (iii), native wages can fall, stay the same or rise, depending upon the strength of the shock and various product and factor market elasticities. As our test case, we reexamine the 1980 "Mariel Boatlift," using Wacziarg's "Channel Transmission" methodology. Our data set includes approximately 6,600 observations for 1979-85 from the Current Population Survey on workers in 9 different retail labor markets and Survey of Buying Power data on retail spending by consumers in Miami and four comparison cities. Our results provide a more complete explanation for why the Boatlift's overall effects on native wages in Miami were benign: Lower wages due to greater labor supply were offset by higher wages due to greater labor demand. We conclude that the demand-augmenting effect of an immigration shock is a significant secondary adjustment process that must be conside...

Research has often focused on how foreign direct investment (FDI) transfers technology from developed economies to less developed economies. Most FDI occurs between developed economies, however, and the country receiving the greatest inflow of FDI is the United States. This paper examines whether such FDI inflows have stimulated growth of the U.S. economy. We apply time-series data to a simultaneous-equation model (SEM) that explicitly captures the bi-directional relationship between FDI and U.S. economic growth. FDI is found to have a significant, positive, and economically important impact on U.S. growth. Also, our SEM estimates reveal that FDI growth is income inelastic. These results imply that: (1) even a technologically advanced country such as the U.S. benefits from FDI, (2) the gains from FDI are very substantial in the long run, and (3) the sustainability of the U.S. current account deficit is enhanced by FDI's positive effect on productivity but undermined by the income inelasticity of FDI. Overall, the results suggest that U.S. policies should focus on keeping the country attractive to foreign direct investors.
