We study joint marketing arrangements by competing firms who engage in price discrimination between consumers who patronize only one firm (single purchasing) and those who purchase from both competitors (bundle purchasers). Two types of joint marketing are considered. Firms either commit to a...

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...

The decision to request a preliminary injunction—a court order that bans a party from certain actions until their lawfulness are ascertained in a final court ruling at trial—is an important litigation instrument in many areas of the law including antitrust, copyright, patents, trademarks,...

The importance of institutions for economic growth has gathered considerable interest. For example, weak institutions can prevent firms from communicating their quality, which can lead to lower welfare. We explore how and whether exporting to markets with strong institutions may alleviate this...

The conventional antitrust wisdom is that the formation of patent pools is welfare en- hancing when patents are complementary, since the pool avoids a double-marginalization problem associated with independent licensing. The focus of this paper is on (down- stream) product development and...

In markets for experience or credence goods adverse selection can drive out higher quality products and services. This negative implication of asymmetric information about product quality for trading and welfare, poses the question of how such markets first originate. We consider a market in...

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...
