Rationality of Migration
利用土耳其数据，通过统计检验支持迁移的理性假说，发现多数迁移者实际收益为负，但少数人获得极高回报，表明迁移像一场彩票。
The paradigm of a rational individual acting on the earnings‐enhancing benefits of migration is subjected to statistical scrutiny, using data from Turkey. Results with robust selectivity correction support the rationality hypothesis: Both migrants and nonmigrants chose the option in which they had comparative advantage. However, the estimated gain from moving is negative for a substantial portion of migrants, whereas a minority realize very high returns. This suggests that migration is a lottery: Individuals are willing to invest in a proposition that has a high probability of yielding negative returns because of the potential for a very large payoff.
