The major interest of antitrust law and economics with respect to predation strategies has been largely twofold. On the one hand, there has been a lively discussion on the question whether predation can basically be a rational strategy for an incumbent facing an entry threat. On the other hand,...

The paper characterises the building blocks of a framework to enforce antipredation rules and subsequently evaluates selected enforcement options in a Cournot-type duopoly predation model. Differentiating between a no rule approach, an ex ante approach and two ex post approaches, it is shown...

The paper provides a comprehensive survey of the economics behind the fight against hard core cartels. Differentiating between four subsequent stages – characterisation, welfare effects, enforcement and evaluation – the paper pays particular attention to cartel detection methods, the...

Due to potential abuse of the market power at wholesale and retail market level for natural gas the Federal Cartel Office in Germany prohibited further forward integration of gas importing firms with retail incumbents from 2005/2006 to 2010. The Authority argued that the very few dominant gas...

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...

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,...

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...

The last couple of years have seen an increasing interest in critical loss analysis, both, in academia and in practice. This development is documented by various research papers, high-level exchanges between antitrust experts as well as an increasing number of case decisions – in the United...

We investigate the relationship between public and private enforcers introducing a more differentiated approach. In contrast to the existing literature, we take into account that the costs and benefits of detection and prosecution and, thus, the usefulness of each enforcement mode may change...
