We study competition among upstream firms when each of them sells a portfolio of distinct products and the downstream has a limited number of slots (or shelf space). In this situation, we study how bundling affects competition for slots. When the downstream has k number of slots, social...

This paper investigates how supply-side factors influence the search for quality content in online and offline environments. We show that lower fixed costs of online publishing reduce the incentives to bundle content, as compared to offline journalism. In the presence of asymmetric information...

We develop a structural econometric framework that allows us to simulate the effects of mergers among two-sided platforms selling differentiated products. We apply the proposed methodology to the Dutch newspaper industry. Our structural model encompasses demands for differentiated products on...

The Internet has drastically altered the nature of competition in the news industry. This article develops a model of price and quality competition between firms in the online news industry. In equilibrium, firms randomise in their pricing strategies and this generates the cross-sectional...

In this paper, we study how the presence of a news aggregator affects competition among (horizontally differentiated) newspapers in the Internet. For this purpose, we build a model of multiple issues which allows each newspaper to choose quality on each issue. Our model provides a micro...

We model a two-sided market with heterogeneous customers and two heterogeneous network effects. In our model, customers on each market side care differently about both the number and the type of customers on the other side. Examples of two-sided markets are online platforms or daily newspapers....

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...

Although many streams of literature have recognized that firms with broader scope often underperform those with greater focus, relatively little research has examined the mechanisms that might account for these diseconomies of scope. One potential mechanism is that uncertainty shocks |events or...

We analyse the effects of the advertising ban on French public television, which came into effect on the 5th of January 2009. The ban forbids commercial advertising on public TV in the time slot 20.00-6.00. By using a difference-in-difference approach we show that advertising which was...

Consumers buy internet access from Internet Service Providers (ISPs) to reach online content providers. Under net neutrality, an ISP is not allowed to discriminate between content providers, even though it might have an incentive to do so. An ISP might want to sell a “fast lane” to content...
