Abstract: Business-as-usual climate-change forecasts point to sharp temperature rises and agriculture yield losses in many regions of Brazil. We study the impact of these changes on internal migration and population distribution. We employ a spatial equilibrium model in which the climate shapes workers' locational choices through the usual amenity-value channel and the novel indirect channel via agriculture wages. Our simulations reveal that migration rates are 9.65% higher, and that 0.9 million more people migrate inter-regionally under future climate conditions. Furthermore, climate change will likely exacerbate the country's regional inequalities, as the most developed regions gain population and welfare while the least developed regions lose.
