The fixed effects (FE) panel model is one of the main econometric tools in empirical economic research. A major practical limitation is that the parameters on time-constant covariates are not identifiable. This paper presents a new approach to grouping FE in the linear panel model to reduce...

Birth rates differ strongly across European states, https://madoc.bib.uni-mannheim.de/55902despite the deep economic harmonisation process related to European integration. This study uses large scale administrative data from France and Germany to analyse and directly compare fertility patterns...

We show that the widespread approach to estimate the career costs of motherhood – so called “child penalties” – is prone to produce biased results, as it pools first-time mothers of all ages without accounting for their differences in characteristics and outcomes. We propose a novel...

This paper explores the potential of an approach suggested by Manski of obtaining nonparametric bounds for treatment effects in evaluation studies without knowledge of the participation process. The practical concern is the effects of continuous vocational training in East Germany. The empirical...

The German apprenticeship training system is generally acknowledged to solve the youth unemployment problem prevalent in many European countries by providing on-the-job training that often leads into subsequent regular employment within the training firms. Little attention has been paid to those...

This study provides novel evidence about the pension wealth elasticity of employment. For the identification we exploit reform-induced variation of pension wealth that is related to the number of children but which does not affect the implicit tax rate of employment. We use a...

We analyze the performance of firms in the German business-related services sector. A quarterly business survey provides the panel data base of our study. Firm performance is measured by the survey respondents' ordinal indication of their changes in total sales. We use a firstorder Markov chain...
