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...

This note gives the condition under which there is an interior optimum rate of population growth in a two-generations-overlapping model. These conditions imply complementarity both in production and in consumption. They also validate Samuelson's serendipity theorem.
