In this Paper, we empirically test for network effects and preannouncement effects in the DVD market. We do this by measuring the effect of potential (incompatible) competition on a network undergoing growth. We find that there are network effects. The data is generally consistent with the...

We examine vertical backward integration in oligopoly. Analysing a standard linear Cournot model, we find that for wide parameter ranges (i) some firms integrate, while others remain separated, and (ii) efficient firms are more likely to integrate vertically. Adopting a reduced-form approach, we...

Payment card associations offer both debit and credit cards and, until recently, engaged in a tie-in on the merchant side through the so-called honour-all-cards (HAC) rule. The HAC rule came under attack on the grounds that the credit and debit card markets are separate markets and that the...

This article provides a review of recent literature in economics on the effect of mass media on politics. The focus is on the welfare effects of mass media. I also discuss the likely implications of existing behavioral theories of media effects, developed outside of economics.

Though new media has become a popular source of information, it is less clear whether or not they have a real impact on economic activity. In authoritarian regimes, where the traditional media are not free, this impact might be especially pronounced. We study consequences of blog postings of a...

Empirical models of differentiated product demand are widely used by both academics and practitioners. While these methods treat carefully the potential endogeneity of price, until recently they have assumed the number and characteristics of the products offered by firms are exogenous. This...

This paper examines incentives for exclusive distribution of content in the presence of advertising. A monopoly seller of content - such as televisation rights to popular sports - may contract with one or both of two competing distributors, charging lump-sum fees. When distributors are...

This paper develops a new insight enabling the empirical study of media capture: minority shareholders of newspapers and readers face similar risks. Both are adversely affected when corrupt insiders use the newspaper for personal profit and receive invisible revenues. This means that relevant...

How much influence can news providers exert on the political process? This paper defines the power of a media organization as its ability to induce voters to make electoral decisions they would not make if reporting were unbiased. While existing media concentration measures are built by...

The paper examines incentives for exclusive distribution of premium television content such as live sports and Hollywood movies. Static analysis shows that a pay TV operator with premium content always chooses to supply its retail rival, using per-subscriber fees to soften competition....
