An experiment is conducted were subjects interact repeatedly to examine the effect of a particular leniency program on cartel formation, cartel stability and cartel recidivism. The program leads to lower prices for three reasons. First, non-cooperators are more persistent in their behavior which...

The information contained in PP-plots is transformed into a single number. The resulting Harmonic Mass (HM) index is distribution free and its sample counterpart is shown to be consistent. For a wide class of CDFs the exact analytical expression of the distribution of the sample HM index is...

The common view that buyer power of insurers may effectively counteract provider market power critically rests on the idea that consumers and insurers have a joint interest in extracting price concessions. However, in markets where the buyer is an insurer, the interests of insurers and consumers...

We experimentally examine the effectiveness of antitrust policies against bidding rings in theEnglish auction (EN) and the first-price sealed-bid auction (FP). We consider both traditionalantitrust policy (without a leniency program) and modern antitrust policy (with a leniencyprogram). In EN,...

P-p plots contain all the information that is needed for scale-invariant comparisons. Indeed, Empirical Distribution Function (EDF) tests translate sample p-p plots into a single number. In this paper we characterize the set of all distinct p-p plots for two balanced sample of size n absent...

Intuitively, extending the period of repose for price fixing agreements enhances the effectiveness of competition policy enforcement. This paper proofs this intuition wrong. As extending the repose period reduces cartel members' defection payoff while it leaves unaltered expected compliance...

We analyze the distribution of economic activity across space for different types of activity and different levels of aggregation. Not only is this distribution highly uneven (independently of the type of activity and level of aggregation), it is also remarkably regular regarding its size...
