While private actions for damages by customers against price-cartels receive much attention, the treatment of other groups affected by such conspiracies is largely unresolved. This article narrows the research gap with respect to suppliers to a downstream price cartel. First, we show that such...

We use consumer panel data to calculate the damage suffered by German consumers due to a detergent cartel that was active between 2002 and 2005 in eight European countries. Applying before-and-after and difference-in-differences estimations we find average overcharges between 6.7 and 6.9 percent...

This paper examines cartel overcharges for the European market. Using a sample of 191 overcharge estimates and several parametric and semi-parametric estimation procedures, the impact of different cartel characteristics and the market environment on the magnitude of overcharges is analyzed. The...

While private actions for damages by customers against price-cartels receive much attention, the treatment of other groups affected by such conspiracies is largely unresolved. This article narrows the research gap with respect to suppliers to a downstream price cartel. First, we show that such...

Cartel detection is usually viewed as a key task of either competition authorities or compliance officials in firms with an elevated risk of cartelization. We argue that customers of hard core cartels can have both incentives and possibilities to detect such agreements on their own initiative...

Although the pricing dynamics of hardcore cartels have been studied intensively from a theoretical perspective, empirical evidence is still rare. We combine publicly available data with a unique private data set of about 340,000 market transactions from 36 smaller and larger customers of German...

While private actions for damages against price-cartels by direct and indirect customers receive much attention, it is largely unresolved to what extent other groups that are negatively affected may claim compensation. This paper focuses on probably the most important one: suppliers to a...

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...

Public and private action against cartels is an internationally recognized cornerstone of antitrust enforcement. Effective private enforcement requires that cartel victims can receive (at least) full compensation for the harm suffered. Academics and competition authorities support this goal with...

We investigate the impact of cartel breakdowns on merger activity. Merging information on cartel cases decided by the European Commission (EC) between 2000 and 2011 with a detailed data set of worldwide merger activity, we find that, first, the average number of all merger transactions increase...
