This paper experimentally analyzes the cartel coordination challenge induced by the discrimination of cartel ringleaders in leniency policies. Ringleaders often take a leading role in the coordination and formation of a cartel. A leniency policy which grants amnesty to all "whistleblowers"...

This paper provides experimental evidence on the formation of partial cartels with endogenous coordination. Firms face a coordination challenge when a partial cartel is to be formed as every firm is better off if it is not inside the cartel but is a free-riding outsider. We introduce a...

This thesis analyzes the underlying strategic and behavioral motivation of firms' (anti) competitive conduct in oligopolistic markets.The first part of this thesis analyzes the strategic motivation for competitive and anti-competitive behavior of firms in an oligopolistic market where product...

This paper experimentally tests the coordination of partial cartels when payoffs are asymmetric. In a two-stage mechanism with communication we analyze the formation of all-inclusive and partial cartels. Firms reject partial cartels if outside firms profit excessively from cartel formation....

This paper emphasizes the importance of including supply-side substitution when assessing mergers in data-driven markets. A review of three merger decisions involving big data giants such as Facebook and Google reveals that competition authorities have so far neglected important aspects of...

This article analyses Big Data strategies with network effects. An incumbent network can abuse its market dominance by implementing a Big Data strategy that “shrouds” data collection. Thereby, only “sophisticated” consumers understand that data collection yields a dis-utility while...

This paper analyses how the endogenous detection of an upstream cartel by a down-stream buyer allows the detecting firm to raise rivals' cost. We model a market with a vertical structure, where a stable all-inclusive cartel is operating in the upstream market which provides an input to a...

This paper provides a definition of “big data” in antitrust. While big data has become an important topic in the antitrust literature and in competition policy practice, no clear-cut definition of big data has been provided yet. This contribution fills a gap clarifying, that a big data...
