This paper studies unshrouding decisions in a framework similar to Gabaix and Laibson (2006), but considers an alternative unshrouding mechanism where the impact of advertising add-on information depends on the number of unshrouding firms. We show that shrouding becomes less prevalent as the...

We conduct experiments testing the relationship between excess capacity and pricing in repeated Bertrand-Edgeworth duopolies and triopolies. We systematically vary the experimental markets between low excess capacity (suggesting monopoly) and no capacity constraints (suggesting perfect...

We study joint marketing arrangements by competing firms who engage in price discrimination between consumers who patronize only one firm (single purchasing) and those who purchase from both competitors (bundle purchasers). Two types of joint marketing are considered. Firms either commit to a...

In this note we analyze the sustainability of collusion in a game of repeated interaction where firms can price discriminate among consumers based on two types of customer data. This work is related to Liu and Serfes (2007) and Sapi and Suleymanova (2013). Following Sapi and Suleymanova we...

This paper summarizes the peculiarities of online markets and discusses recent antitrust cases related to online markets. Following a brief description of the online markets' characteristics and potential tendencies for concentration the paper first discusses the antitrust allegations and...

We analyze the pricing behavior of firms when explicit partial cartels have formed in experimental markets through communication. Using a repeated, asymmetric capacity constraint price game, we show that, in line with theory, a partial cartel is sufficient to increase market prices for all...

We investigate how the structure of the distribution channel affects tacit collusion between manufacturers. When selling through a common retailer, we find - in contrast to the conventional understanding of tacit collusion that firms act to maximize industry profits - that colluding...

We characterize mixed-strategy equilibria in a setting with capacity constrained suppliers which can charge location based prices to different customers. The equilibrium prices weakly increase in the transport distance between supplier and customer, whereas the margins decrease. Despite prices...
