This paper reviews the empirical evidence on commercial media bias (i.e., advertisers influence over media accuracy) and then introduces a simple model to summarize the main elements of the theoretical literature. The analysis provides three main policy insights for media regulators: i) Media...

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...

This paper studies mergers in two-sided markets by estimating a structural supply-and-demand model using data from the 1996-2006 merger wave in U.S. radio. It makes two main contributions. First, it identifies the conflicting incentives of merged firms to exercise market power on both sides of...

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....

Given that over half the revenues of global newspaper publishing come from advertising (80% in the US and 57% in OECD countries, OECD, 2010), we study how media firms internalize the effect of their own coverage on advertisers' sales and hence on their own advertising revenues. We show, within a...

In this paper we study, as in Jeon-Menicucci (2009), competition between sellers when each of them sells a portfolio of distinct products to a buyer having limited slots. This paper considers sequential pricing and complements our main paper (Jeon- Menicucci, 2009) that considers simultaneous...

We consider competition among n sellers when each of them sells a portfolio of distinct products to a buyer having limited slots (or shelf space). We study how bundling affects competition for slots. When the buyer has k number of slots, efficiency requires the slots to be allocated to the best...

While cities understandably want oversight over some aspects of installing this infrastructure, such as digging up neighborhood streets, there is no economic rationale for local franchising of video services. The need to obtain a franchise represents little more than a barrier to entry....

This paper presents a model of media competition with free entry when media operators are financed both from advertisers and customers. The relation between advertising receipts and sales receipts, which are both complementary and antagonist, is different if media operators impose a price or a...

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...
