Return Migration, Self‐selection and Entrepreneurship
研究了返乡移民是否更可能创业，发现若不控制两次移民阶段的自我选择偏差，会低估返乡对创业的正面影响，利用莫桑比克内战和农业瘟疫等外生冲击进行估计。
Abstract Are return migrants more entrepreneurial? Existing literature has not addressed how estimating the impact of return migration on entrepreneurship is affected by double unobservable migrant self‐selection, both at the initial outward migration and at the final inward return migration stages. This paper exploits exogenous variation provided by the civil war and the incidence of agricultural plagues in Mozambique, as well as social unrest and other shocks in migrant destination countries. The results lend support to overall negative unobservable return migrant self‐selection, which results in an under‐estimation of the effects of return migration on entrepreneurial outcomes when using a ‘naïve’ estimator that does not control for self‐selection at both the initial migration and at the final return migration stages.
