THE SHORT‐RUN AND LONG‐RUN FACTOR‐MARKET CONSEQUENCES OF IMMIGRATION TO THE UNITED STATES*
运用生产理论方法，利用1980年美国123个大都市区的普查数据，评估移民对国内工资和就业的短期与长期影响，并报告不同设定下的弹性估计。
ABSTRACT. 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 immigrants, native workers, and capital. Census cross‐sectional data for 1980 and for 123 metropolitan areas are used. Empirical estimates are reported for alternative functional forms with special attention devoted to required curvature conditions which have frequently been violated in previous work. Elasticity estimates are reported for alternative settings, including for the short run where we view domestic factor prices as given and the long run where we treat them as flexible.
