TEMPORARY EMIGRATION AND WELFARE: THE CASE OF LOW‐SKILLED LABOR
研究临时移民对母国福利的影响，通过一般均衡模型模拟发现，当移民在国外工作8-12年时，母国非移民的福利最大，且理想时长随工资差异、移民成本和权利保护程度增加。
This article studies the implications of temporary emigration for the welfare of a source country. The framework is one of general equilibrium, where the economy's stocks of both capital and labor are endogenously determined by the saving and migration decisions of optimizing agents. Simulations of the model suggest that for realistic values of the parameters, welfare of nonmigrants of the source country is maximized when the migrants are employed abroad for a period in the range of roughly 8–12 years. The ideal duration is found to be an increasing function of the international wage differential, migration costs, and the degree to which the rights of migrants are protected in the host country.
