The authors analyzed the implications of targeted advertising on the equilibrium level of channel profile differentiation (e.g., in terms of political positioning), in free-to-air broadcasting industries. When consumers have no preferences over program content (e.g., entertainment vs. news)...

Counterfeiting of trademarked products is an increasing problem in national and international trade. We contribute to the analysis of how counterfeiting affects markets by extending the work of Grossman and Shapiro (1988a) on consumption externalities in prestige good markets. We model a general...

This paper first presents stylized evidence showing how the date of the introduction of competition policy is correlated with country size. Smaller countries tend to adopt competition policy later. We thereafter present a simple theoretical model with countries of different size and firms...

We examine the relation between rent control and prices of owner occupied housing in the presence of different qualities of housing. While a rent ceiling and the price of condominiums are substitutes if housing is undifferentiated, it is shown that this is not necessarily the case when housing...

Recently, the European Commission has decided to implement a simplified procedure in the context of vertical integration. If the combined market shares of the merging firms are less than 25 percent, upstream and downstream, the Commission will consider the merger harmless. The purpose of this...

In media markets, the value of advertisement exposure depends on circulation, and media consumers’ valuation is affected by advertising. This paper analyzes media market competition in a duopoly framework. There exist symmetric and asymmetric equilibria in terms of firm size. There is less...

This paper analyses the effects of mergers on price and welfare in markets facing congestion and derives conditions under which a merger is consumer welfare improving, even in the absence of marginal cost savings. In our context a merger basically has two effects. First, it obviously increases...

In this not we show that the results developed in Singh and Vives (1984) are sensitive to the duopoly assumtion (Rand Journal of Economics 15, 546-554). If there are more than two firms, prices may be higher under price competition than unde quantity competition. This will be the case if quality...
