We analyse the treatment effects of a large scale German active labour market program. Modellprojekte Bürgerarbeit is a modified public employment scheme, with an activation period as a first step. Using data from individual employment records we perform matching estimations to analyse the...

We estimate the effects on wage and employment growth rates of the introduction and subsequent increases of the minimum wage in the main construction industry of Germany. Using a regional dataset constructed from individual employment histories, we exploit the spatial dimension and border...

Temporal work flexibility is often viewed as means to improve the reconciliation of family and work. By exploiting theGerman re-unification and the particularities of the labor market of the German Democratic Republic, I show that flexitime allows mothers to spend more time with their children....

We use a 100% sample of social security panel micro data for estimating the effects of a minimum wage in the German construction sector. In 1997, a wage floor was introduced at different rates in West and East Germany. For analysing the impact of this natural experiment we conceptually follow a...

We analyse the impact of retraining for the unemployed on future labour market success, and estimate effects separately for different target occupations. We use German registry data and apply statistical matching methods. The results show that on average, after a period with strong lock-in...

A large and highly used number of treatment effects estimators rely on the unconfoundedness assumption ("selection on observables") which is fundamentally non testable. When evaluating the effects of labor market policies, researchers need to observe both variables that affect treatment...

To which extent does an increase in effectiveness of a public employment agency on the one hand and a reduction of unemployment benefits on the other reduce unemployment? Using the recent labour market reform in Germany we find that an improved agency explains substantial part of the observed...

For instrumental-variable estimation using binary instruments, we offer simple methods to obtain policy-relevant insights beyond local average treatment effects. We demonstrate the methods by evaluating an element of choice introduced into active labour market policy in Germany by a reform in...

In Germany, due to special rules 15- to 24-year-old welfare recipients, registered with Public Employment Office, are highly targeted by mandatory activation policies. This paper investigates the effects of the special rules in terms of enhancing the (re-)employment probability, increasing...

In course of the ''Hartz IV'' reform implementation in January 2005, Germany has tightened unemployment benefit sanctions. In addition, the regulations with respect to job offer acceptance have been strengthened radically. As non-compliant behavior is supposed to entail benefit sanctions, we...
