We provide an empirical assessment of EC cartel enforcement decisions between 2000 and 2011. Following an initial characterisation of our dataset, we especially investigate the determinants of the duration of cartel investigations. We are able to identify several key drivers of investigation...

The paper develops a four-step framework to detect anticompetitive horizontal mergers. In the first step, an estimate of the impact of the merger on the market price needs to be derived. Subsequent, the second step of the framework has to assess whether such a predicted price increase would be...

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...

Leniency programs as a tool for cartel detection and cartel destabilization, have been implemented since the early nineties. Theoretical work has shown that leniency programs can be eff ective in enhancing cartel detection and deterrence, but these e ffects are not straight-forward. It is even...

The duration of appellate court proceedings is an important determinant of the efficiency of a court system. We use data of 234 firm groups that participated in 63 cartels convicted by the European Commission between 2000 and 2012 to investigate the determinants of the duration of the subsequent...

The appeals process – whereby the losing party of an administrative or judicial decision can seek reconsideration of their arguments before a higher institution – is an important mechanism to correct legal errors and to improve existing laws and regulations. We use data of 467 firm groups...

We analyze a large merger in the Dutch banking market during the financial crisis using disaggregated data. Based on a merger simulation model, we evaluate merger-induced changes in the interest rates for savings accounts. We find that the merging banks decreased interest rates by 3 to 5 percent...

A central motivating factor for studying price markups is their effect on consumer welfare. Reported estimates of (firm-level) price markups in the literature, however, are often focused on industry or cross-country comparisons. These treat different industries equally rather than based on how...

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...

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...
