To the best of our knowledge, most of the few methodological studies which analyze the impact of faked interviews on survey results are based on ?artificial fakes? generated by project students in a ?laboratory environment?. In contrast, panel data provide a unique opportunity to identify data...

A particular shortcoming of panel surveys is potential bias arising from selective attrition. Based on data from the German Socio-Economic Panel Study (SOEP) we analyze potential artifacts (level, structure, inequality of income) by comparing results from two independently drawn panel...

Typically, laboratory experiments suffer from homogeneous subject pools and self-selection biases. The usefulness of survey data is limited by measurement error and by the questionability of their behavioral relevance. Here we present a method integrating interactive experiments and...

In this paper we evaluate the employment effects of job creation schemes on the participating individuals in Germany. Job creation schemes are a major element of active labour market policy in Germany and are targeted at long-term unemployed and other hard-to-place individuals. Access to very...

Persistently high unemployment, tight government budgets and the growing scepticism regarding the effects of active labour market policies (ALMP) are the basis for a growing interest in evaluating these measures. This paper intends to explain the need for evaluation on the micro- and...

Overall, children in Germany live in households with below average incomes; therefore social policies that address the vulnerable position of Germany?s children are necessary. These policies should cover targeted financial transfers as well as improvements in day care provision for children....

Using panel data for West Germany and Great Britain, we show that there are striking differences in overtime work and overtime compensation in the two countries in the 1990s. Our estimates reveal that the observed overtime patterns affect both the evolution of the monthly labour earnings...

Most evaluation studies of active labour market policies (ALMP) focus on the microeconometric evaluation approach using individual data. However, as the microeconometric approach usually ignores impacts on the non-participants, it should be seen as a first step to a complete evaluation which has...

We assess the labour supply effects of two 'making work pay' reforms in Germany. We provide evidence in favour of policies that distinguish between low effort and low productivity by targeting individuals with low wages rather than individuals with low earnings. In assessing the policies we...
