Long‐term consequences of short‐term precipitation shocks: evidence from Brazilian migrant households
研究发现，短期强降水冲击会损害从农村永久迁移到城市的家庭的长期收入，这可能与农村家庭在冲击后耗尽生产性资产、被迫接受城市较低收入有关，提示了农村自然灾害与城市贫困之间的潜在联系。
Abstract We find that large short‐term precipitation shocks damage the long‐term income of households that have permanently migrated from rural to urban areas. This outcome is consistent with the behavior of credit‐constrained rural households who are willing to accept lower long‐term income in urban areas following the depletion of their productive assets during an adverse shock. Our empirical evidence suggests that there may be a link between large precipitation shocks in rural areas and urban poverty. Further exploration is warranted on the mechanisms by which natural disasters cause these long‐term losses.
