Using data from the SOEP, we analyze the wellbeing impact of underemployment through overeducation to examine a broader definition of employment loss. Persons leaving a job through exogenous reasons but entering directly into immediate employment may not find a perfect employment match and...

Using a large panel data set of German manufacturing establishments, this paper investigates the impact of competition on training incidence as well as on the number of trained workers. According to theory, one would expect a negative relationship between product market competition and firms'...

The classical Heckman (1976, 1979) selection correction estimator (heckit) is misspecified and inconsistent if an interaction of the outcome variable and an explanatory variable matters for selection. To address this specification problem, a full information maximum likelihood estimator and a...

In a randomized controlled trial involving 700 obese persons assigned to three experimental groups, we test whether financial incentives have heterogeneous effects on weight reduction. While two treatment groups obtain EUR 150 and EUR 300, respectively, for achieving an individually-assigned...

Although public support for renewable energy promotion in Germany is strong, the required power line construction has incited a groundswell of opposition from residents concerned about the impacts on their neighborhoods. This paper evaluates a large randomized one-shot binary-choice experiment...

The classical Heckman (1976, 1979) selection correction estimator (heckit) is mis-specified and inconsistent if an interaction of the outcome variable and an explanatory variable matters for selection. To address this specifi cation problem, a full information maximum likelihood estimator and a...

This paper analyzes whether moderate weight reduction improves subjective health perception in obese individuals. To cure possible endogeneity bias in the regression analysis, we use randomized monetary weight loss incentives as instrument for weight change. In contrast to related earlier work...

Despite general support for the transition towards renewable energies, local opposition may hamper the required power line construction. This paper evaluates a large randomized one shot binary choice experiment with about 10,000 observations to examine the effect of annual community...

The second and third generation of immigrants have been the centre of a lively debate about the economic integration of immigrants into their host societies, but there is little empirical evidence on the German case. In this study I comprehensively portray the labour market outcomes of second...
