This paper provides a new perspective on intergenerational mobility in the United States in the late 19th and early 20th centuries. We devise an empirical strategy that allows to calculate intergenerational elasticities between fathers and children of both sexes. The key insight of our approach...

The intergenerational elasticity of income is considered one of the best measures of the degree to which a society gives equal opportunity to its members. While much research has been devoted to measuring this reduced-form parameter, less is known about its underlying structural determinants....

We use Swedish adoption data combined with police register data to study parent-son associations in crime. For adopted sons born in Sweden, we have access to the criminal records of both the adopting and biological parents. This allows us to assess the relative importance of pre-birth factors...
