Brain drain or brain dilution tax : a sending countryʼs perspective

I investigate how taxing immigrants and redistributing the collected funds as educational subsidies influence human capital accumulation and growth in the source economy. The analysis is performed in a two-country growth model with endogenous fertility, in which public knowledge spillovers from the more advanced destination economy amplify the productivity of investment in children’s education in the sending country. I demonstrate that, while in the short run, the source economy accumulates more human capital if the subsidies are provided domestically, if the spillover effect is strong enough, in the long run, it can accumulate more human capital if education is subsidized in the destination country.
