Advanced economic instruments like simulation models are enjoying an increased popularity in practical antitrust. There is hope that they being quantitative predictive economic evidence can substitute for qualitative structural analysis and lead to unambiguous results. This paper demonstrates...

The literature identifies a significant drop in merger control enforcement activity on both sides of the Atlantic during the last decade. Furthermore, this drop in enforcement activity is convincingly connected to enforcement problems on the sides of the competition agencies. This paper goes...

This paper provides a comparative analysis of methods for the empirical ex post evaluation of merger control decisions. It develops a competition-policy oriented framework of assessment criteria for the leading evaluation methods and applies them to structural modeling and simulation,...

Naturally, competition policy is based on competition economics made applicable in terms of law and its enforcement. Within the different branches of competition economics, modern industrial economics, or more precisely gametheoretic oligopoly theory, has become the dominating paradigm both in...

The recent Impala Judgment by the CFI on the Sony/BMG Decision by the Commission represents the most important ruling on collective dominance since Airtours. We review both the Decision and the Judgment and derive implications for the institutional and substantive development of EU Merger...

An increasingly important part of contemporary merger control both in the US and the EU is unilateral effects analysis, particularly with regard to oligopolistic mergers. In practice, this requires econometric analyses of past market data and, above all, the construction of simulation models in...
