Our aritcle "Go where the wind doesn’t blow: Climate damages heterogeneity and future migrations ", in collaboration with Aurélie Méjean and Stéphane Zuber has been published in the Faere Working Paper Series. You can download it here.
In the context of climate change, migration can be considered as an adaptation strategy to reduce populations' exposure to climate damages. Those damages are very heterogeneous across regions. In this paper, we study migration induced by climate change damages. To do so, we estimate the socio-economic determinants of migration, focusing on economic damages. We then model endogenous migration in an integrated assessment model based on those estimates. We highlight the importance of the heterogeneity of the damages distribution to explain migration flows due to climate change. We find that high levels of climate damages globally do not necessarily induce large climate migration. Rather, large differences in exposure between regions may lead to substantial migration.
