The paper offers an overview of the literature on bundling in the telecommunications sector and its application in the Spanish market. We argue that the use of bundling in the provision of services is associated to technological reasons. Therefore, there appears no need to regulate bundling...

We study a retail benchmarking approach to determine access prices for interconnected networks. Instead of considering fixed access charges as in the existing literature, we study access pricing rules that determine the access price that network i pays to network j as a linear function of the...

We develop a model of the interacting markets for online content and offline products. We portray content providers and the search engine as competing platforms that intermediate in the product market (a horizontal relation), while also vertically related in the content market. Explicitly...

We study approval rules in a model where horizontal merger proposals arise endogenously as the outcome of negotiations among the firms in the industry. We make two main points. First, relatively ine¢ cient merger proposals succeed with positive probability. That is, the negotiation process may...

Site licensing of electronic journals has been revolutionizing the way academic information is distributed. However, many librarians are concerned about the possibility that commercial publishers might abuse site licensing by practicing bundling. In this paper, we analyze how bundling afects...

We use experiments to study the efficiency effects for a market as a whole of adding the possibility of forward contracting to a pre-existing spot market. We deal separately with the cases where spot market competition is in quantities and where it is in supply functions. In both cases we...

While the theoretical industrial organization literature has long argued that excess capacity can be used to deter entry into markets, there is little empirical evidence that incumbent firms effectively behave in this way. Bagwell and Ramey (1996) propose a game with a specific sequence of moves...

The purpose of this paper is to analyze the effect of multimarket contact on the behavior of pharmaceutical firms controlling for different levels of regulatory constraints using IMS MIDAS database. Theoretically, firms that meet in several markets are expected to be capable of sustaining...

This paper considers a monopolist selling two objects to a single buyer with privately observed valuations. We prove that if each buyer’s type has a non-negative virtual valuation for each object, then the optimal price schedule is such that the objects are sold only in a bundle; weaker...
