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...

We consider the regulation of a monopoly facing consumers that may evade payments, an important issue in public utilities. To maximize total surplus, the regulator sets the price and socially costly transfers, ensuring that the monopoly breaks-even. With costly effort, the firm can deter...

We consider a non-durable good monopoly that collects data on its customers in order to profile them and subsequently practice price discrimination on returning customers. The monopolist's price discrimination scheme is leaky, in the sense that an endogenous fraction of consumers choose to incur...

A durable good monopolist faces a continuum of heterogeneous customers who make purchase decisions by comparing present and expected price-quality offers. The monopolist designs a sequence of price-quality menus to segment the market. We consider the Markov Perfect Equilibrium (MPE) of a game...
