本文研究了发展中国家鼓励农村向城市移民的福利效应。为此，我们建立并分析了一个动态的一般均衡模型，该模型具有丰富的移民动机。我们估计该模型复制了一个实地实验的结果，该实验补贴了孟加拉国农村的季节性移民，导致移民和消费的显着增加。我们发现，移民补贴带来的福利收益来自于为弱势农村家庭提供更好的保险，而不是通过放松对那些在城市地区生产率高而被困在农村地区的人的信贷限制来纠正空间分配不当。
This paper studies the welfare effects of encouraging rural–urban migration in the developing world. To do so, we build and analyze a dynamic general‐equilibrium model of migration that features a rich set of migration motives. We estimate the model to replicate the results of a field experiment that subsidized seasonal migration in rural Bangladesh, leading to significant increases in migration and consumption. We show that the welfare gains from migration subsidies come from providing better insurance for vulnerable rural households rather than from correcting spatial misallocation by relaxing credit constraints for those with high productivity in urban areas that are stuck in rural areas.
