LOCAL IMPACTS OF CLIMATE CHANGE-INDUCED MIGRATION

First Essay: We exploit temporally disaggregated data on weather anomalies andtemporary migration to examine the effect of the former on the latter, and the ef-fectiveness of migration as a coping mechanism to maintain consumption in the faceof adverse weather conditions. We construct a continuous measure of migration thatincreases both with the number of people leaving, and with the length of time theystay away. Our results show that, while weather anomalies do trigger temporary mi-gration, they only do so when they occur before or rather early in the growing season.This suggests that households have a limited ability to respond to unexpected shockswhen they occur late in the season. We also find that weather anomalies can affectmigration patterns several months after they take place and discuss possible mecha-nisms. We find that, conditional on these temporal patterns, households lacking onlabor force endowment and social networks are particularly limited in their abilityto use migration as a coping mechanism and remain, consequently, more vulnerableto shocks. Our analysis reveals how temporal aggregation of weather shocks, widelyimplemented in previous studies, can obscure substantial heterogeneity in migrationresponse, as well as their ability to mitigate adverse impacts.
