We measure the welfare consequences of endogenous quality choice in imperfectly competitive markets. We introduce the concept of a "quality markup" and measure the relative welfare consequences of market power over price and quality. For U.S. paid-television markets during 1997-2006, we find...

We examine cost-reducing investment in vertically-related oligopolies, where firms may be vertically integrated or separated. Analyzing a standard linear Cournot model, we show that: (i) Integrated firms invest more than separated competitors. (ii) Vertical integration increases own investment...

We examine vertical backward integration in a reducedform model of successive oligopolies. Our key findings are: (i) There may be asymmetric equilibria where some firms integrate and others remain separated, even if firms are symmetric initially; (ii) Efficient firms are more likely to integrate...

We investigate the existence of an "electoral cycle bias" in the timing of media coverage of news with high political value. In particular, we analyze how the electoral cycles at the regional level influence the coverage of news about corruption scandals in the Italian Regional Health Systems by...

We develop a model to study the political economy implications of information gatekeeping, i.e., a policy of granting access only to friendly media outlets and denying access to critical ones. While an incumbent prefers positive bias, granting access improves her re-election probability only if...

This paper provides a model of the market for news where profit-maximizing media outlets choose their editors from a population of rational citizens. The analysis identifies a novel mechanism of media bias: the bias in a media outlet's news reports is the result of the slanted endogenous...

Television is the dominant entertainment medium for hundreds of millions. This chapter surveys the economic forces that determine the production and consumption of this content. It presents recent trends in television and online video markets, both in the US and internationally, and describes...

I study the business practices of the Comédie française, the main theater in Paris, between 1680 and 1793. The theater was an actors' partnership and operated within a (contested) oligopoly. Newly available data provide revenues by price category for over 32,000 performances. Attendance varied...

What is the role of the media in coordinating and mobilizing insurgency against a foreign military occupation? We analyze this question in the context of the Nazi-fascist occupation of Italy during WWII. We study the effect of BBC radio counter-propaganda (Radio Londra) on the intensity of...

The spread of propaganda, misinformation, and biased narratives from autocratic regimes, especially on social media, is a growing concern in many democracies. Can censorship be an effective tool to curb the spread of such slanted narratives? In this paper, we study the European Union's ban on...
