Labor immigration and long-run welfare in a growth model with heterogenous agents and endogenous labor supply

Abstract.

This paper examines the consequences of labor immigration in an OLG economy in which agents have an elastic labor supply and differ with respect to degrees of altruism and rates of time preference. It focuses on three substantive questions. First, how do immigrants influence the bequest motive of altruistic natives? Second, what impact do immigrants have on the labor supply of natives? Finally, how does immigration affect the long-run welfare of both altruistic and non altruistic natives?
