Platform-run marketplaces may exploit third-party sellers' data to develop competing products, but potential for future competition can deter sellers' entry. We explore how this trade-off affects the platform's referral fee and its own entry decision. We first characterize the platform's optimal...

This paper studies the role of exchange policies as a price discrimination device in a sequential screening model with heterogeneous goods. In the first period, agents are uncertain about their ordinal preferences over a set of horizontally differentiated goods, but have private information...

Abstract

We study the interactions between fuel efficiency improvements in the transport sector and the oil market, where the efficiency improvements are policy-induced in certain regions of the world. We are especially interested in feedback mechanisms of fuel efficiency such as the rebound effect,...

I investigate a simple model of advance-purchase contracts as a mode of financing costly projects. The analysis can easily be reinterpreted as a model of the monopolistic provision of excludable public goods under private information. An entrepreneur has to meet some capital requirement in order...

We consider an unhealthy good, such as a sugar-sweetened beverage, the health damages of which are misperceived by consumers. The sugar content is endogenous. We first study the solution under “pseudo” perfect competition. In that case a simple Pigouvian tax levied per unit of output but...

Economic theory suggests that monopoly prices hurt consumers but benefit shareholders. But in a world where individuals or households can be both consumers and shareholders, the impact of market power on inequality depends in part on the relative distribution of consumption and corporate equity...

We study a two-sided market where a platform attracts firms selling differentiated products and buyers interested in those products. In the unique subgame perfect equilibrium of the game, the platform fully internalizes the network externalities present in the market and firms and consumers all...

How are a firm's size and market power related to one another? Combining micro-data about producers and consumers, we document that while firms mainly grow by selling to more customers, their markups are only associated with their average sales per customer. To study the macroeconomic...

This paper studies how a firm should make pricing and transparency decisions when consumers care about supply chain characteristics. We first show how preferences that account for price and unit cost constrain the firm’s pricing power and profit. Surprisingly, we find that the firm may be...
