Favorable Self-Selection and the Internal Migration of Young White Males in the United States
用1985-1991年美国青年纵向调查数据，检验国内迁移者是否存在有利的自我选择，发现迁移前白人男性收入已高于类似非迁移者。
This study offers an alternative empirical technique to test whether the favorable self-selection hypothesis applies to internal migrants in the United States. Our empirical specification attempts to determine if prospective migrants possess unobserved traits such as higher ability or motivation which influence their earnings potential relative to nonmigrants. Using NLSY [National Longitudinal Survey of Youth] data for 1985 through 1991 we find some support for the favorable self-selection hypothesis for white males who move from one SMSA to another. Prior to their move prospective migrants enjoy a consistent advantage in annual wage and salary income relative to nonmigrants with similar earnings-related characteristics. (EXCERPT)
