This paper provides a thorough analysis of oligopolistic markets with positive demand-side network externalities and perfect compatibility. The minimal structure imposed on the model primitives is such that industry output increases in a firm's rivals' total output as well as in the expected...

This paper studies the efficient use of prioritization in Amazon's Twitch.tv, taking into account the trade-off between entry and congestion. I specify and estimate supply and demand models for live video, and a congestion model. Using technological shocks, I identify congestion costs for...

In this article I analyze the effects of a recent reform intended to decrease switching costs in the cellular industry. The reform, implemented in Chile in 2012, allowed cell phone users to switch operators without any contract restriction while keeping their wireless number. Its aim was the...

Online platforms, such as Google, Facebook, or Amazon, are constantly expanding their activities, while increasing the overlap in their service offering. In this paper, we study the scope and overlap of online platforms' activities, when they are endogenously determined. We model an expansion...

There are examples of entry in two-sided markets, where first entrants occupy a ‘central location’ and serve agents with ‘intermediate tastes,’ while later entrants are niche players. Why would the first entrant choose to become a ‘general’ platform, given that later entrants will...

We examine the profitability and welfare implications of targeted price discrimination in two-sided markets. First, we show that equilibrium discriminatory prices exhibit novel features relative to discriminatory prices in one-sided models and uniform prices in two-sided models. Second, we...

In this paper, we build a model of the news market where advertisers allocate their ads between a social media platform and a news website that is the content creator. Our main objective is to evaluate a policy intervention that aims to foster news creation by transferring revenues from social...

We analyze a duopoly game in which products are initially differentiated in variety and quality. Each consumer has a most preferred variety and a quality valuation. Customization provides ideal varieties but has no effect on product qualities. The firms first choose whether to customize their...

In this paper we estimate a structural model of search for differentiated products, using a unique dataset of consumer online search for hotels. We propose and implement an identification strategy that allows us to separately estimate consumer's beliefs, search costs and preferences. Learning...

We compare four approaches to network neutrality and network management regulation in a two-sided market model: (i) no variations in Quality of Service and no price discrimination; (ii) variations in Quality of Service but no price discrimination; (iii) variations in Quality of Service and price...
