The success of the Kindle e-book platform and the increased popularity of e-books among members of the reading community have attracted extensive interest in the high-tech industry. New platform providers are jumping in the market to compete for device and e-book sales. In this paper, we model...

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...

This paper investigates the scope of indirect network effects in the home video game industry. We argue that the increasing prevalence of non-exclusive software gives rise to indirect network effects that exist between users of competing and incompatible hardware platforms. This is because...

This paper links empirical literature on the use of price as an entry deterring mechanism with literature on the effect of multi-market contact on competition. The analysis uses a dataset of cable TV system prices to provide evidence that incumbent cable TV firms use price to deter entry by...

We analyse a newspaper market where two editors first choose the political position of their newspaper, then set cover prices and advertising tariffs. We build on the work of Gabszewicz, Laussel and Sonnac (2001, 2002), whose model we take as the stage game of an infinitely repeated game, and...

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...

Although we have many tools to understand the effect of regulation on competition, we know little about the importance of enforcement in explaining the impact of regulation. For this purpose, this paper uses data from Spanish local television industry in Spain from 1995 through 2001, which...

The YouTube platform reduces fixed entry costs for local artists but also lowers the cost of access to international superstars. The net effect is an empirical question. We study the effect of YouTube on the market for music, focusing on converging tastes for international hits. We consider...

We study optimal cartel prices in a two-sided market. We present a simple model showing that prices above the two-sided monopoly price may prevail on one side of a two-sided market as a means to enhance the sustainability of the cartel. We prove that in such a case a higher benefit from the...

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...
