We study the optimal pricing strategy of a monopolist selling homogeneous goods to multiple buyers over multiple periods. The customers choose their time of purchase to maximize their payoff that depends on their valuation of the product, the purchase price, and the utility they derive from past...

Usury is a frequent occurrence in consumer credit markets and particularly affects low-income households. Systemic usury exploits poverty by shifting usury into additional products and leveraging usury gains by stringing together individual loan agreements. This paper reviews the economic...

A platform matches agents from two sides of a market to create a trading opportunity between them. The agents subscribe to the platform by paying subscription fees which are contingent on their reported private types, and then engage in strategic interactions with their matched partner(s). A...

Usury is a frequent occurrence in consumer credit markets and particularly affects low-income households. Although the term usury conjures images of a greedy individual consciously acting to exploit the weak bargaining position of another by deceitful and even fraudulent means, we consider it as...

In nonlinear pricing environment with correlated types, we characterize optimal selling mechanisms when buyers could form a coalition to coordinate their reports and to arbitrage on the goods. We find that when the types of agents are weakly positively correlated, the optimal weakly...

Based on the critical assumption of strategic complementarity, this paper builds a general model to describe and solve the screening problem faced by the monopolist seller of a network good. By applying monotone comparative static tools, we demonstrate that the joint presence of asymmetric...

We study the market for vaccinations considering income heterogeneity on the demand side and monopoly power on the supply side. A monopolist has an incentive to exploit the external effect of vaccinations and leave the poor susceptible in order to increase the willingness to pay of the rich....

Cet article intègre la question environnementale à l’étude de secteurs caractérisés par des producteurs de bien vierge avec un pouvoir de marché, confrontés à un secteur du recyclage. On utilise un modèle où la production de bien vierge par un monopole est polluante, contrairement à...

Digital platforms operate in multisided markets providing services through the internet to two or more distinct groups of users, between which there are indirect network effects. Direct network effects are frequently present within each group. Therefore, online platforms usually present both...
