Abstract

Using a comprehensive dataset of bilateral migration flows and employing the Palmer index as a proxy for climate change, we demonstrate that conflict acts as an amplifying mechanism for climate-induced migration. Our results show that, as drought conditions worsen, middle- and high-income countries experiencing conflict are more inclined to have higher rates of international out-migration. In particular, we find that one standard deviation contraction in the Palmer index, indicating drier conditions, is associated with a 12% increase in out-migration flows from middle/high-income countries experiencing conflict. We also explore spatial autocorrelation and observe positive and significant origin-and destination-spatial dependence effects. Our findings contribute to understanding the intricate dynamics of climate change, conflict, and international migration while offering insights into migration patterns across countries.
