Immigrant workers will be evaluated by their ability to speak English as well as by their other skills. The empirical work in this article add resses the hypothesis that there is an economic cost to English langu age deficiency both in occupation-specific earnings and in (cross-sec tional) occupational mobility. This analysis suggests that it is cost ly to be deficient in English, but the cost is ethnically and occupat ionally specific. Hispanics have a higher cost for English language d eficiency than Asians at every skill level. Copyright 1988 by University of Chicago Press.

The 1986 Immigration Reform and Control Act (IRCA) granted amnesty to approximately 1.7 million long‐term unauthorized workers in an effort to bring them “out of the shadows” and improve their labor market opportunities. An analysis of wages using panel data for a sample of legalized men provides evidence that wage determinants are structurally different after amnesty for them but not for the comparison group as measured during the same time periods. The wage penalty for being unauthorized is estimated to range from 14% to 24%. The wage benefit of legalization under IRCA was approximately 6%.
