Abstract This paper investigates the impact of food crises on forced international migration (FIM) using a structural gravity model. Using a new dataset that captures the severity, duration, and causes of food crises, we find that such crises increase FIM. Mild crises tend to push migrants toward developed, distant countries, while severe crises shift flows to closer destinations. This suggests that as food crises intensify, financial barriers grow, limiting the ability to migrate long distances. However, these patterns are strongly influenced by liquidity constraints, which are shaped by migration costs and migrants’ economic resources.
