This study estimates the causal effect of working hours on health. We deal with the endogeneity of working hours through instrumental variables techniques. In particular, we exploit exogenous variation in working hours from statutory workweek regulations in the German public sector as an...

This paper examines the causal effects of a major change in the German parental leave benefits on fertility. I use the unanticipated reform of 2007 to assess how a move from a means-tested to an earnings-related benefit affects higher-order births. By using data from the Mikrozensus, I find that...

We study the development of teenage fertility in East and West Germany using data from the German Socioeconomic Panel (SOEP) and from the German Mikrozensus.

The data is consistent with national accounts statistics provided by the German Federal Statistical Office and is based on investments in...

The use of large datasets for macroeconomic forecasting has received a great deal of interest recently. Boosting is one possible method of using high-dimensional data for this purpose. It is a stage-wise additive modelling procedure, which, in a linear specification, becomes a variable selection...

This paper applies component-wise boosting to the topic of regional economic forecasting. Component-wise boosting is a pre-selection algorithm of indicators for forecasting. By using unique quarterly real gross domestic product data for two German states (the Free State of Saxony and...
