The market for payments is an important two-sided one, where consumers benefit from increased merchant acceptance of payment cards and vice versa. The dependence between the decisions that are made on each side of the market results in various network externalities that are often discussed but...

Platforms often display their products ahead of third-party products in search. Is this due to consumers preferring platform-owned products or platforms engaging in self-preferencing by biasing search towards their own products? What are the welfare implications? I develop a structural model of...

Telemonitoring devices can be used to screen consumer characteristics and mitigate information asymmetries that lead to adverse selection in insurance markets. Nevertheless, some consumers value their privacy and dislike sharing private information with insurers. In a second-best efficient...

We show that exchanges of cost information in models with entry may benefit consumers in a wide range of market structures, including multimarket models with independently distributed costs and duopolies. These results contrast with previous findings in models without entry

In a wide variety of social settings (e.g. crime, education, political activism, technology adoption), players' returns to their efforts depend on how much effort others exert. Modeling these situations as a network game with strategic complementarities, we show that a player's cycle centrality...

This contribution provides a game theoretical derivation of market demand as a function of the level and distribution of income in the considered economy: if (i) the price is low, everyone buys the good; if (ii ) the price is high, only the rich buy the good (a status good in a narrow sense). If...
