In this paper I investigate the causal returns to education for different educational groups in Germany. I circumvent potential drawbacks of IV by employing a new method by Klein and Vella (2010). In this approach identification is not based on instruments but on the presence of heteroskedasticity. Using data from the German Socio-Economic Panel Study (SOEP) I find that the causal return to education is 8.5% for the entire sample, 2% for graduates from the basic school track and 11% for graduates from a higher school track. Across these groups the endogeneity bias in simple OLS regressions varies significantly. This confirms recent evidence in the literature on Germany. Various robustness checks support my findings.
