We introduce three types of consumer recognition: identity recognition, asymmetric preference recognition, and symmetric preference recognition. We characterize price equilibria and compare profits, consumer surplus, and total welfare. Asymmetric preference recognition enhances profits compared...

The two central pricing rules contained in most antirust laws are prohibitions of below-cost pricing and prohibitions of discriminatory pricing. This article shows that the rule against discriminatory pricing may actually induce firms to charge exclusionary below-cost prices, even in the...

In the context of an infinitely repeated capacity-constrained price game, we endogenize the composition of a cartel when firms are heterogeneous in their capacities. When firms are sufficiently patient, there exists a stable cartel involving the largest firms. A firm with sufficiently small...

The primary objective of the paper is to identify the pattern of non-linear pricing in the E-Commerce market and its usage. This paper investigates the post-digitization non-linear pricing strategy of selling commodities.The paper shows that in the digital market place non-linear pricing...

Recent empirical studies suggest that there is a rising trend of market power across sectors in advanced economies. We contribute to this line of research by providing industry-specific evidence for German manufacturing industries, based on representative high-quality firm level data from...

We examine the relation between consumer search and equilibrium prices when collusion is endogenously determined. We develop a theoretical model and show that average price is a U-shaped function of the measure of searchers: prices are highest when there are no searchers (local monopoly power)...

Over the past decade, an increasing number of firms have delegated pricing decisions to algorithms in consumer markets such as travel, entertainment, and retail; business markets such as digital advertising; and platform markets such as ride-sharing. This trend, driven primarily by the increased...

This paper provides a snapshot of the state of the literature on payment cards, particularly from the perspective of interchange fees and the economics literature on two-sided markets. The paper aims to integrate a wide range of theoretical papers with the relevant empirical research and...

In this paper I set forth an antitrust remedy for the oligopolistic pricing problem. Oligopoly pricing resembles a repeated prisoners' dilemma game. Each firm has an incentive to moderately lower its price and thus increase its sales at its competitors' expense. However, each firm knows that its...

Price dynamics are characterized when a price-fixing cartel is concerned about creating suspicions of the presence of a cartel. A dynamical extension of static models yields the counterfactual prediction that the cartel initially raises price and then gradually lowers it. An alternative...
