Abstract: | We study climate change and international migration in a two-country overlapping generations model with endogenous climate
change. Our main findings are that climate change increases migration; small impacts of climate change have significant impacts
on the number of migrants; a laxer immigration policy increases long-run migration, aggravates climate change, and increases
north–south inequality if climate change impacts are not too small; and a greener technology reduces emissions, long-run migration,
and inequality if the migrants’ impact to overall climate change is large. The preference over the policies depends on whether
the policy maker targets inequality, wealth, the environment, or the number of migrants. |
