We use a unique private data set of about 340,000 invoice positions from 36 smaller and larger customers of German cement producers to study the value of such transaction data for an estimation of cartel damages. In particular, we investigate, first, how structural break analysis can be used to...

We use publicly available price data from the German cement industry to estimate the cartelinduced price increase. We apply two different comparator-based approaches – the ‘before and-after’ approach and the ‘difference-in-differences’ approach – and especially study the impact of...

It is widely believed that globalization affects the extent of employment and wage responses to economic shocks. To provide evidence for this, we analyze the effect of firms' exporting behavior on the elasticity of labor demand. Using rich, German administrative linked employer-employee panel...

We study the competitive effects of five liquidations and six mergers in the domestic U.S. airline industry between 1995 and 2010. Applying fixed effects regression models we find that route exits due to liquidation lead to substantially larger price increases than mergerrelated exits. Within...

There is still considerable dispute about the magnitude of labor supply elasticities. While differences in micro and macro estimates are recently attributed to frictions and adjustment costs, we show that relatively low labor supply elasticities derived from microeconometric models can also be...

We analyze different alternatives how a common unemployment insurance system for the euro area (EA) could be designed and assess their effectiveness to act as an insurance device in the presence of asymmetric macroeconomic shocks. Running counterfactual simulations based on micro data for the...

Die Auseinandersetzung um die Weiterentwicklung des Ehegattensplittings in Richtung einer stärkeren steuerlichen Berücksichtigung von Kindern hält in der Regierungskoalition an. Wie kann ein Familiensplitting ausgestaltet werden? Welche Wirkungen ergeben sich auf das Steueraufkommen? Welche...

Derzeit werden verschiedene Kombilohnmodelle zur Bekämpfung der Arbeitslosigkeit von Niedrigqualifi zierten diskutiert. Wie unterscheiden sich diese Modelle? Welche Wirkungen haben sie auf das Arbeitsangebot? Welche Kosten sind damit verbunden?

In this article, we discuss reform elements of "Hartz IV". This includes, on the one hand, merging unemployment benefits with housing benefits and the additional child benefits (Kinderzuschlag) and, on the other hand, reducing disincentives which prevent the recipients from earning higher...
