Die Theorie des Wettbewerbs als Entdeckungsverfahren behauptet, daß die Ergebnisse des Wettbewerbes nicht vorhergesagt werden können, weil hierzu Tatsachen benötigt würden, die durch ihn erst entdeckt werden sollen. Dann wäre es allerdings unmöglich, Aussagen über Wettbewerb empirisch zu...

This article presents results of a laboratory experiment testing whether the effectiveness of a moderate leniency program depends on market size. Against theory, the results indicate that a moderate leniency program is not preferable to a policy which only includes fines for detected cartels,...

Public reputation mechanisms are an effective means to limit opportunistic behavior in markets suffering from moral hazard problems. While previous research was mostly concerned with the influence of exogenous feedback mechanisms, this study considers the endogenous emergence of reputation...

We consider two mechanisms to procure differentiated goods: a request for quote and an English auction with bidding credits. In the request for quote, each seller submits a price and the inherent quality of his good. Then the buyer selects the seller who offers the greatest difference in quality...

Advances in technology enable sellers to price discriminate based upon a customer's revealed purchasing intentions. E-tailers can track items already in a quot;shopping cartquot; and item level RFID tags enable retailers to do the same in bricks and mortar stores. As retailers attempt to...

We report an experiment designed to investigate markets with consumer search costs. In markets where buyers are matched with one seller at a time, sellers are predicted to sell at prices equal to buyers' valuations. However, we find sellers post prices that offer a more equal division of the...

We report a policy experiment that illustrates a potential problem of using historical pass-through rates as a means of predicting the competitive consequences of projected firm-specific cost savings in antitrust contexts, particularly in merger analysis. The effects of cost savings on welfare...

We investigate the relationship between collusive behavior in Bertrand oligopoly experiments and subject heterogeneity in risk preferences. We find that risk aversion is positively associated with tacit collusion when the goods are complements, but find no evidence of collusive behavior when the...

We investigate pricing behavior of sellers in duopoly markets with posted prices and market power. The two treatment variables are given by tie-breaking rules and divisibility of the price space. The first treatment variable deals with the rule under which demanded units are allocated between...
