Oligopoly has been among the first topics in the experimental economics. Over half a century, some 150 papers have been published. Each individual paper was interested in demonstrating one effect. But in order to do so, experimenters had to specify many more parameters. That way they have...

We consider competition among sellers when each of them sells a portfolio of distinct products to a buyer having limited slots. We study how bundling affects competition for slots. Under independent pricing, equilibrium often does not exist and hence the outcome is often inefficient. When...

In this paper we study, as in Jeon-Menicucci (2009), competition between sellers when each of them sells a portfolio of distinct products to a buyer having limited slots. This paper considers sequential pricing and complements our main paper (Jeon- Menicucci, 2009) that considers simultaneous...

This work is focused on identifying a circular pull production control system (PPCS) and make emphasis on the presence of a stability attribute. It is an introductory paper to an extended study of macroeconomic financial stability in a physically open but systemic closed system. Previous work...

The fundamental contribution of the paper is to contest the view that greater market contestability has non-negative effects on market performance. In a model where employees pose a threat of potential entry, we demonstrate that a reduction in barriers to entry causes no fall in industry price...

This paper compares one-part and two-part pricing in a discrete-continuous choice model, providing more extensive welfare results than prior literature. Under two-part pricing, firms may set fixed fees with or without `unit-price commitment,' where the lack of unit-price commitment is consistent...

Leniency policies and rewards for whistleblowers are being introduced in ever more fields of law enforcement, though their deterrence effects are often hard to observe, and the likely effect of changes in the specific features of these schemes can only be observed experimentally. This paper...

France Telecom (FT), SFR and Bouygues Telecom (BT) have been fined by France’s Conseil de la Concurrence (CC) for organizing a mobile phone cartel with stable market shares (one-half, one-third and one-sixth respectively) and for directly exchanging commercial information. While not contesting...

Antitrust authorities view the possibility of entry as a key determinant of whether a proposed merger will be harmful to society. This paper examines the effects of horizontal mergers in models of non-localized, differentiated Bertrand oligopoly that allow for free entry. The analysis of the...

A cartel is socially not desirable. But is it a normative problem? And has merger control reason to be concerned about tacit collusion? Neither is evident once one has seen that the members of a cartel face a problem of strategic interaction. It is routinely analysed in terms of game theory....
