This paper investigates the collusive and competitive effects of algorithmic price recommendations on market outcomes. These recommendations are often non-binding and common in many markets, especially on online platforms. We develop a theoretical framework and derive two algorithms that...

A usual assumption in the theory of collusion is that cartels are all-inclusive. In contrast, most real-world collusive agreements do not include all firms that are active in the relevant industry. This paper studies both theoretically and experimentally the formation and behavior of partial...

This paper considers the collusive stability of downstream competition in a vertical market with network externalities and cost asymmetry. A dynamic collusion game is constructed, and backward induction is employed to solve the subgame perfect Nash equilibrium. We show that larger network...

In 2006, Russia amended its competition law and added the concepts of “collective dominance” and its abuse. This was seen as an attempt to address the common problem of “conscious parallelism” among firms in concentrated industries. Critics feared that the enforcement of this provision...

This paper analyzes the role of patience in a repeated Bertrand duopoly where firms bargain over which collusive price and market share to implement. It is shown that the least patient firm's market share is not monotone in its own discount factor

This paper explores the effects of communication in market entry games experimentally. It is shown that communication increases coordination success substantially and generate inferior outcomes for consumers when market entry costs are symmetric. Such effects are not observed when costs are...

Predatory pricing doctrine is currently a dead area of the law. To proceed beyond summary judgment, a plaintiff must prove the predation created a “dangerous probability” of supracompetitive pricing as the mechanism for recouping the losses “invested” in the predation. This requires...

From the perspective of competitors, competition may be modeled as a prisoner’s dilemma. Setting the monopoly price is cooperation, undercutting is defection. Jointly, competitors are better off if both are faithful to a cartel. Individually, profit is highest if only the competitor(s) is...
