Food insecurity is a pressing global concern and little is known of its economic outreach. This paper quantifies the effects of food crises on international forced migration (FIMs) flows using a structural gravity model. We construct a novel dataset that measures to the severity, intensity, and causes of the food crises. Results suggest that even mild food crises tend to increase international forced migration. Severe food crises skew FIM toward less developed countries. Our results are consistent with the fact that food crises tighten liquidity constraints on migration, worsening as food crises intensify.
