  • Does regime change affect intergenerational mobility? Evidence from German reunification
  • 2019
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • This study uses the natural experiment of German reunification and a difference-in-differences approach to test whether the political and economic transition in East Germany in 1990 affected intergenerational occupational and educational mobility. Applying data from the German Socio-Economic Panel Study (SOEP), I show that German reunification did neither strongly affect occupational nor educational mobility. These findings are robust to operationalizing social origin in various ways. Admittedly, reunification may have had small effects on occupational and educational mobility that cannot be uncovered with data currently available. However, my findings rule out that there were large effects of German reunification on intergenerational mobility. These findings are at odds with theories that argue that institutions strongly affect intergenerational mobility.

  • When less conditioning provides better estimates : Overcontrol and collider bias in research on intergenerational mobility
  • 2019
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • The counterfactual approach to causality has become the dominant approach to understand causality in contemporary social science research. Whilst most sociologists are aware that unobserved, confounding variables may bias estimates of causal effects, the issues of overcontrol and collider bias have received comparatively less attention. In particular, widely used practices in research on intergenerational mobility require conditioning on variables that are endogenous to the process of the intergenerational transmission of advantage. I review four of these practices from the viewpoint of the counterfactual approach to causality and show that overcontrol and collider biases arise when these practices are implemented. I use data from the German Socio-Economic Panel Study (SOEP) to demonstrate the practical consequences of these biases for conclusions about intergenerational mobility. Future research on intergenerational mobility should reflect more upon the possibilities of bias introduced by conditioning on variables.
