The dynamics of immigration policy with wealth-heterogeneous immigrants

"In this paper we consider a simple intertemporal economy in which immigrants, if admitted, bring heterogeneous amounts of capital. We show that under certain conditions there is a level of immigration which maximizes the economy's capital-labor ratio, and that this level of immigration is the preferred choice of a majority of the economy's citizens. We then characterize, in an overlapping generations setting, the dynamics of capital accumulation and immigration policy, which can include multiple steady state equilibria and a sensitivity of immigration levels to changes in the economy's technology growth rate"--Federal Reserve Bank of Dallas web site.
