March 2018Should they stay or should they go? Climate Migrants and Local Conflicts
with Valentina Bosetti, Giovanni Peri: w24447
There is extensive evidence that higher temperature increases the probability of local conflict. There is also some evidence that emigration represents an important margin of adaptation to climatic change. In this paper we analyse whether migration influences the link between warming and conflicts by either attenuating the effects in countries of origin and/or by spreading them to countries of destination. We find that in countries where emigration propensity, as measured by past diaspora, was higher, increases in temperature had a smaller effects on conflict probability, consistent with emigration functioning as "escape valve" for local tensions. We find no evidence that climate-induced migration increased the probability of conflict in receiving countries.
October 2015The Migration Response to Increasing Temperatures
with Giovanni Peri: w21622
Climate change, especially the warming trend experienced by several countries, could affect agricultural productivity. As a consequence the income of rural populations will change, and with them the incentives for people to remain in rural areas. Using data from 116 countries between 1960 and 2000, we analyze the effect of differential warming trends across countries on the probability of either migrating out of the country or from rural to urban areas. We find that higher temperatures increased emigration rates to urban areas and to other countries in middle income economies. In poor countries, higher temperatures reduced the probability of emigration to cities or to other countries, consistently with the presence of severe liquidity constraints. In middle-income countries, migration repr...
