Data and Code for: Responses to Extreme Temperatures: Migrant Networks and International Migration from El Salvador

This repository contains the data and code used to replicate the analyses in the paper, "Extreme Temperatures and International Migration: Evidence from El Salvador." <br><br>This study shows that exposure to extreme temperatures significantly increases international migration from El Salvador. Extreme temperatures reduce corn yields, leading producers to decrease their use of post-harvest inputs and demand for agricultural workers. These income losses, combined with established U.S. migration networks, increase emigration. The findings highlight how international migration serves as an adaptation response to extreme temperatures when destination networks are strong and migration remains financially feasible. This pattern is not unique to El Salvador—globally, approximately 30 million farms in low-income settings may face similar dynamics given access to remittances.<br>These materials allow full replication of the results presented in the paper.
