Disabled insurance (DI) beneficiaries lose benefits if labor incomes exceed certain thresholds (so called cash-cliffs ). The high implicit taxation of employment income is considered one of the prime reasons for the low outflow from the disability insurance. This paper presents the results of...

Using data from the German Socio-Economic Panel, this paper analyses the effects of spending part of adolescents’ leisure time on playing music or doing sports, or both. We find that while playing music fosters educational outcomes compared to doing sports, particularly so for girls and...

In this note, we show that the OLS and fixed-effects (FE) estimators of the popular differ-ence-in-differences model may deviate when there is time varying panel non-response. If such non-response does not affect the common-trend assumption, then OLS and FE are consistent, but OLS is more...

Based on new, exceptionally informative and large German linked employer-employee administrative data, we investigate the question whether the omission of important control variables in matching estimation leads to biased impact estimates of typical active labour market programs for the...

Based on new, exceptionally informative and large German linked employer-employee administrative data, we investigate the question whether the omission of important control variables in matching estimation leads to biased impact estimates of typical active labour market programs for the...

We investigate whether the distance between the next sport facilities and children's homes matter for their sports activities inside and outside of sport clubs. Our analysis is based on a large and informative cross-section of individual data of children and their families, the so-called KIGGS...

Based on new, exceptionally informative and large German linked employer-employee administrative data, we investigate the question whether the omission of important control variables in matching estimation leads to biased impact estimates of typical active labour market programs for the...

Using exceptionally rich linked administrative and survey information on German welfare recipients we investigate the health effects of transitions from welfare to employment and of assignments to welfare-to‐work programmes. Applying semi‐parametric propensity score matching estimators we...

The effects of active labour market policies (ALMP) on individual employment chances and earnings are evaluated by nonparametric instrumental variables based on Swiss administrative data with detailed re-gional information. Using an exogenous variation in the participation probabilities across...

This survey gives a brief overview of the literature on the difference-in-difference (DiD) estimation strategy and discusses major issues using a treatment effect perspective. In this sense, this survey gives a somewhat different view on DiD than the standard textbook discussion of the...
