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...

Labor market programs may affect unemployed individuals' behavior before they enroll. Such ex ante effects may differ according to ethnic origin. We apply a novel method that relates self-reported perceived treatment rates and job search behavioral outcomes, such as the reservation wage or...

This paper considers the problem of aggregation in the case of large linear dynamic panels, where each micro unit is potentially related to all other micro units, and where micro innovations are allowed to be cross sectionally dependent. Following Pesaran (2003), an optimal aggregate function is...

This paper evaluates a job search assistance program for unemployment insurance recipients. The assignment to the program is dynamic. We provide a discussion on dynamic treatment effects and identification conditions. In the empirical analyses we use administrative data from a unique...

The evaluation of labor market policies has become an important issue in many European countries. In recent years, many of them have opened their administrative databases for evaluation studies. The advantages of administrative data are straightforward: they are accurate, contain a large number...

This study reports results from an empirical investigation of business services sector firms that (start to) export, comparing exporters to firms that serve the national market only. We estimate identically specified empirical models using comparable enterprise level data from France, Germany,...

Using the approach suggested by Gabaix (Econometrica 2011) this paper demonstrates that idiosyncratic shocks in the largest firms are important for an understanding of aggregate volatility in German manufacturing industries. The implications of this finding for theoretical and empirical research...

This paper analyzes how policy changes affect shareholder wealth in the context of environmental regulation. We exploit the unique and unexpected German reaction to the Fukushima Daiichi nuclear disaster, which involved the immediate shutdown of almost half of Germany's nuclear reactors while...

The German Child Benefit ("Kindergeld") is paid to legal guardians of children as a cash benefit. This study employs exogenous variations in the amount of child benefit received by households to investigate the extent to which these various changes have translated into an improvement in the...

In Germany, there is a vivid political debate on introducing a general statutory minimum wage. In this paper, we study the effects of minimum wages on labor supply using a structural household model where we distinguish between married and single households. In the model, labor supply of married...
