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...

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...

While others have examined the implementation and/or the stringency of enforcement of antitrust laws in post-socialist economies, this paper is the first study that attempts to explain the determinants of antitrust enforcement activity across post-socialist countries using economic and political...

The optimal competition policy when licensing is an alternative to a merger, which has the intention of transferring a superior technology, and is derived in a differentiated goods duopoly, as in the cases of Cournot and Bertrand competition. We show that whenever both royalties and fixed fees...

We model a two-sided market with heterogeneous customers and two heterogeneous network effects. In our model, customers on each market side care differently about both the number and the type of customers on the other side. Examples of two-sided markets are online platforms or daily newspapers....

This article investigates how antitrust agencies should structure the disclosing of information about effciency gains from interested parties (merging .rms, and competitors) in merger control. We analyze the particular case of a horizontal merger withdanger of foreclosure, where welfare can...

This paper surveys the literature on the manufacturing sector in South Africa, focusing on concentration and markup levels, with a view to inform policy. The literature has employed a number of different measures of industrial concentration, namely, the Gini and Rosenbluth indices, the Occupancy...

In this paper, we develop a market screening model to detect inconstancies in price changes. Although there is a long history of industrial organization research of collusion, price setting behavior, and conduct - a robust model to detect structural changes in market structure was missing so...

This paper investigates the rationales of exclusive dealing (ED), which is one of the most common forms of vertical restraint and attracts intense policy debates in anti-trust regulations. Based on a survey of the theoretical literature, we derive several hypotheses relative to the anti- and...
