This paper studies a “market creating” firm that offers a matching environment, by charging an access fee, to a population of users who wish to form a match. We focus on an environment where users only observe a signal from their randomly assigned partner's type and the signal...

We present a model of industry standard setting with two-sided asymmetric information about the existence of intellectual property. We provide an equilibrium analysis of (a) firms' incentives to communicate ideas for improvements of an industry standard, and (b) firms' decisions to disclose the...

How did the diffusion of the Internet affect performance and product quality in the airline industry? We argue that the shift to online distribution channels has changed the way airlines compete for customers - from an environment in which airlines compete for space at the top of travel agents'...

Newspapers' advertising revenues have declined sharply in recent decades. We build a model to investigate the consequences on newspapers' content and prices of a reduction in advertisers' willingness to pay. Newspapers choose the size of their newsroom, and readers are heterogeneous in the...

We develop a model of dynamic platform formation under positive platform externalities. Users can switch between an incumbent and entrant platforms, switching opportunities arise stochastically and users can choose whether to accept or reject an opportunity to switch. For homogeneous users, we...

How does the development of formal standards for information and communication technologies shape the behavior of firms that may need the technologies to develop new products and services? We argue that standardization lowers the search costs of identifying important intellectual property rights...

The demand for electronic books (e-books) and the e-book readers are complementary. On the one hand, the emergence of e-book readers such as Amazon's Kindle has triggered the recent growth of the e-book market. On the other hand, several issues in the e-book market can affect the future of the...

We study the effects of competition and interoperabilty in platform markets. To do so, we adopt an approach of competition in net fees, which is well-suited to situations where users pay additional charges, after joining, for on-platform interactions. Compared to other approaches, net fees...

In their seminal 1985 paper, Katz and Shapiro study systems compatibility in settings with one-sided platforms and direct network externalities. We consider systems compatibility when competing platforms are two-sided and there are indirect network externalities to develop an explanation why...

I examine the role of word of mouth in consumer's product discovery process and its implications for the firm. A monopolist supplies an assortment of horizontally differentiated products and consumers search for a product that matches their taste by sampling products from the assortment or by...
