This paper builds on earlier work that used a general‐equilibrium model to show that reducing employment of unauthorized immigrants in the United States through a tighter border‐security policy lowers the average income of legal residents. Here we exploit further the detail available in the general‐equilibrium model to look at distributional effects, recognizing that the policy increases wage rates for low‐paid legal workers. We assess the social welfare effect on legal workers using a constant elasticity of substitution social welfare function. We contrast our general‐equilibrium approach to immigration analysis with the more commonly used partial‐equilibrium, econometric approach. (JEL D63, J61, C68)
