We demonstrate that the popular Farrell-Shapiro-framework (FSF) for the analysis of mergers in oligopolies relies regarding its policy conclusions sensitively on the assumption that rational agents will only propose privately profitable mergers. If this assumption held, a positive external...

The model proposed in this paper explains three stylized facts derived from case evidence: Cartel formation is more likely (i) when the industry has been hit by a negative profitability shock under the condition that (ii) this shock is rather persistent. (iii) This pattern is independent from...

Regression methods are commonly used in competition lawsuits for, e.g., determining overcharges in pricefixing cases. Technical evaluations of these methods' pros and cons are not necessarily intuitive. Appraisals that are based on case studies are descriptive but need not be universally valid....
