In linking self-employment before and after migration, the often-cited home-country self-employment hypothesis states that immigrants who come from countries with large self-employment sectors are themselves more likely to have been self-employed and hence have a higher propensity for self-employment in their destination country. Using Swedish data, this study shows that the first part of the hypothesis, that origin-country average rates of self-employment can be used to approximate individual experience, is false; but the second part, the connection between self-employment before and after migration, is true if the measurement is done on the individual level. Migrants who have been self-employed before migration accumulate entrepreneurial human capital, making future self-employment a more desirable labor market alternative vis-a-vis wage employment. But because of migrant selection, this association cannot be captured by aggregate measures, and this is the reason why the home-country self-employment hypothesis, although intuitive, has underperformed in previous empirical tests.

在移民之前和之后将自谋职业联系起来：移民选择和人力资本

在将移民前后的自谋职业联系起来时，经常被引用的母国自谋假说指出，来自拥有大量自雇部门的国家的移民自己更有可能自雇，因此倾向更高。在目的地国家从事自谋职业。使用瑞典的数据，这项研究表明，假设的第一部分是虚假的；该假设的第一部分是原籍国平均自雇率可以用来近似个人经验。但是第二部分，即在迁移之前和之后的个体经营之间的联系是正确的，如果该测量是在个人层面上进行的。在移民之前是自营职业的移民积累了企业家的人力资本，使未来的自谋职业成为有薪就业相对更可取的劳动力市场替代方案。但是由于移民的选择，这种联系无法通过总体测度来捕捉，这就是为什么本国自雇假说尽管直观但在先前的实证检验中表现不佳的原因。
