We contrast a standard deterministic signaling game with one where the signal-generating mechanism is stochastic. With stochastic signals a unique equilibrium emerges that involves separation and has intuitive comparative-static properties as the degree of signaling depends on the prior type...

We study firms' incentives to acquire private information in a setting where subsequent competition leads to firms' later signaling their private information to rivals. Due to signaling, equilibrium prices are distorted, and so while firms benefit from obtaining more precise private information,...

Asymmetric information is a classic example of market failure that undermines the efficiency associated with perfectly competitive market outcomes: the "lemons" market. Credible certification, that substantiates unobservable characteristics of products that consumers value, is often considered a...

We study zero-rating, a practice whereby an Internet service provider (ISP) that limits retail data consumption exempts certain content from that limit. This practice is particularly controversial when an ISP zero-rates its own vertically integrated content, because the data limit and ensuing...

Regulators and the firms they regulate interact repeatedly. Over the course of these interactions, the regulator collects data that contains information about the firm's idiosyncratic private characteristics. This paper studies the case in which the regulator uses information gleaned from past...

We study a Hotelling framework in which customers first pay a monopoly platform to enter the market before deciding between two competing services on opposite ends of a Hotelling line. This setup is common when modeling competition in Internet content provision. We find that standard...

We develop a model for two-sided markets with consumers and producers, who interact through a platform. Typical settings for the model are the market for smartphones with phone users, app producers, and smartphone operating systems; or the video game market with game players, video game...

We consider merger remedies of the U.S. Department of Justice's Antitrust Division and the U.S. Federal Trade Commission between 2008 and 2017. Traditionally one distinguishes between structural and behavioral remedies' and structural remedies are generally considered to be more effective and...

The conventional wisdom is that the formation of patent pools is welfare enhancing when patents are complementary, since the pool avoids a double-marginalization problem associated with independent licensing. This conventional wisdom relies on the effects that pooling has on downstream prices....
