Abstract

This article analyzes the link between climate change and international migration. We use a two-country overlapping generations model with endogenous climate change, in which the production in the North generates climate change which negatively affects the productivity of the South. Our main findings are: (i) climate change will increase migration; (ii) small impacts of climate change have significant impacts on the number of migrants; (iv) a laxer immigration policy increases long- run migration, reduces climate change, increases North-South inequality if DRTS are significant; (v) a greener technology reduces long-run migration, provides a double- dividend in favor of the environment, reduces inequality if the migrants' impact to overall climate change is large. The preference over the policies thus depends on whether the policy maker targets inequality, wealth, the number of migrants or the environment, but the qualitative ranking between the policies does not change if the policies are costly.
