Using data from the German Socio Economic Panel, I analyze the incidence, financing, and returns to workplace training in Germany for the years 1986 to 1989. Much of this training seems general, and is provided to workers by their employer at no direct cost. While workers typically report larger productivty gains from the training during work hours, such training has lower returns than training undertaken during leisure time. Workers with higher earnings growth seem more likely to participate in training. I deal with this selection problem by estimating models that allow for inidividual level heterogeneity in earnings growth rates.
