Temporary Migration and Endogenous Risk Sharing in Village India
研究了临时迁移与非正式风险分担之间的相互影响，利用印度农村面板数据估计模型，发现农村就业计划虽减少迁移但削弱风险分担，降低政策福利收益。
When people can self-insure via migration, they may have less need for informal risk sharing. At the same time, informal insurance may reduce the need to migrate. To understand the joint determination of migration and risk sharing, I study a dynamic model of risk sharing with limited commitment frictions and endogenous temporary migration. First, I characterize the model. Second, I structurally estimate the model using the new ICRISAT panel from rural India. Third, I introduce a rural employment scheme. The policy reduces migration and decreases risk sharing, lowering the welfare gain of the policy.
