We discuss strategic ways that sellers can use tying and bundling with requirement conditions to extract consumer surplus. We analyze different types of tying and bundling creating (i) intra-product price discrimination; (ii) intra-consumer price discrimination; and (iii) inter-product price...

We study the issue of integrating real and financial decisions in a monopoly firm with risk-averse decision-makers. To that end, we combine the decisions of the firm and of the shareholders in a very simple but robust model, with uncertainty in the real market and CARA preferences. We show the...

It is difficult to elminated all market power in electricity markets and it is therefore frequently suggested that some market power should be tolerated: extra revenues contribute to fixed cost recovery, facilitate investment and increase security of supply. This suggestion implicitly assumes...

We examine welfare effects of real-time pricing in electricity markets. Before stochastic energy demand is known, competitive retailers contract with final consumers who exogenously do not have real-time meters. After demand is realized, two electricity generators compete in a uniform price...

We examine an infinite horizon model of quality growth in a durable goods monopoly market. The monopolist generates new quality improvements over time and can sell any available qualities, in any desired bundles, at each point in time. Consumers are identical and for a quality improvement to...

This paper is an outgrowth of the filings in the FCC's broadband openness proceeding that focused on the issue of networks neutrality. Newly available data confirm that competition in the broadband access marketplace is limited. Wireless broadband access services are unlikely to act as effective...

This document (of 279 pages) comprises the proceedings of a roundtable on predatory foreclosure held by the OECD's Competition Committee at the OECD in October 2004. The roundtable addressed various strategies that dominant firms use to eliminate or deter competition, focusing on predatory...

A general equilibrium analysis of monopoly power is proposed as an alternative to the partial equilibrium analyses of monopolization common to most antitrust texts. This analysis introduces the notion of a cost minimizing market equilibrium. The empirical implications of this equilibrium concept...

Between 2004 and 2008, Microsoft was fined by the European Commission with 1.67 billion Euros for abuse of dominant position and tying products on the European operating system market. The paper delivers a short history of the case, and analyzes both Microsoft and European Commission actions...

We argue that at the level of the national economy, an import quota transforms national welfare in the form of government revenues and consumer surplus into producer surplus to the domestic monopolist protected by the quota. An import quota confers substantial market power to the local...
