THE SHORT-RUN AND LONG-RUN FACTOR-MARKET CONSEQUENCES OF IMMIGRATION TO THE UNITED-STATES

This paper applies the production-theory approach to assess the impact on domestic wages and employment of immigration to the United States. Inputs are disaggregated between recent immigrants, non-recent immigr ants, native workers, and capital. Census cross-sectional data for 198 0 and for 123 metropolitan areas are used. Empirical estimates are rep orted for alternative functional forms with special attention devoted to required curvature conditions which have frequently been violated i n previous work. Elasticity estimates are reported for alternative set tings, including for the short run where we view domestic factor price s as given and the long run where we treat them as flexible.
