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...

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...

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...

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...

We use T-100 traffic data and DB1B fare data from the U.S. Department of Transportation to identify patterns and effects of entry by network carriers and low-cost carriers in non-stop U.S. airline markets. For the sample period from 1996 to 2009, we find that entry activity of low-cost carriers...

The paper investigates the construction of a low cost airline network by analyzing JetBlue Airways' entry decisions into nonstop domestic U.S. airport-pair markets between 2000 and 2009. Adopting duration models with time-varying covariates, we find that JetBlue consistently avoided concentrated...

The article studies the evolution of the U.S airline industry from 1995 to 2009 using T-100 traffic data and DB1B fare data from the U.S. Department of Transportation. Based on a differentiation in market size and major players, entry and exit, concentration, fares, service, costs and profits,...

Theoretical research has investigated the relevance of entry-inducing effects as countervailing factor to a merger-related increase in market power. We use route-level data for the America West Airlines – US Airways merger (2005) to investigate whether such an effect can be identified...

We study the consumer welfare effects of mergers in airline networks. Based on the development of a general classification of affected routes, we apply a difference-indifferences approach to exemplarily investigate the price effects of the America West Airlines - US Airways merger completed in...
