CU Denver Associate Professor Andrea Velásquez and co-authors recently published "Responses to Extreme Temperatures: Migrant Networks and International Migration from El Salvador" in the American Economic Journal: Economic Policy. The study examines how extreme heat affects migration decisions among agricultural households in El Salvador. The researchers find that an additional week of extreme heat during the corn-growing season reduces corn production and demand for agricultural labor, increasing the likelihood that a corn-farming household sends a member abroad the following year. These migration responses are strongest in communities with established migration networks in the United States, suggesting that migrant networks can provide an important way for households to cope with climate-related economic shocks. The research highlights the connection between climate change, agricultural livelihoods, and international migration, particularly in settings where households have limited access to other ways of managing economic risk.
