This paper explores the potential of an approach suggested by Manski of obtaining nonparametric bounds for treatment effects in evaluation studies without knowledge of the participation process. The practical concern is the effects of continuous vocational training in East Germany. The empirical...

This study analyses the effects of public-sector-sponsored continuous vocational training and retraining in East Germany after unification with West Germany in 1990. It presents econometric estimates of the average gains from training participation in terms of employment probabilities, earnings,...

In East Germany, active labour market policies (ALMPs) are used on a large scale to contain fast rising unemployment after unification. This paper evaluates the effects for participants in public employment programmes (PEPs), that are an important part of ALMPs. It focuses on individual...

This paper proposes a nonparametric method for evaluating treatment effects in the presence of both treatment endogeneity and attrition/non-response bias, using two instrumental variables. Making use of a discrete instrument for the treatment and a continuous instrument for...

The paper studies the returns from enterprise-related continuous vocational training on individual earnings, unemployment probabilities, and other labor market indicators in East Germany after unification. It attempts to solve the intrinsic identification problem of such evaluation problems...

Retraining the labor force to match the demands of a modern economy is an important task during the transition process from a centrally planned to a market economy. This need is particularly pressing in East Germany, because the transition process is much faster there than in the rest of Eastern...
