This study considers the anti-competitive effect of fixed-fee pricing, such as the one seen in a recent antitrust case in Japan. We show that fixed-fee pricing has stronger exclusionary effect than the per-use pricing's exclusionary effect. However, the restriction on usage of fixed-fee pricing...

The domestic brand bias has been one of the most commonly used explanations for automobiles price differences across international borders in the EU. Using a panel dataset comprising of 51 models across 21 EU member states, we take advantage of cross country heterogeneity, and find that,...

This paper investigates the effects of exclusive territories in the presence of upstream competition. We consider the vertical dealings among two upstream firms and four downstream firms and find that exclusive territories may be more beneficial for consumers and more harmful for producers than...

Consider the contracting problem of an input supplier dealing with several firms that compete in an output market. We show that, contrary to the key result of the previous literature, an input supplier's profit can increase with the number of downstream firms if the upstream firm is not a...

We analyze the effectiveness of antitrust enforcement in repeated oligopoly models in which both fines and detection probabilities depend on the cartel price. Such fines reflect actual guidelines. Inspections based on monitoring of market prices imply endogenous detection probabilities. Without...

Melnik et al. [Melnik, A., Shy, Oz, Stenbacka, R. Assessing market dominance. Journal of Economic Behavior and Organization 68, 63-72] have proposed a new statistic to assess market dominance. In this comment we expand their discussion of certain mathematical properties in their analysis and...

We study the effect of more information of firms about consumers' preferences on collusion sustainability within a differentiated Hotelling duopoly. We show that the increase of information may increase or decrease collusion sustainability, depending on the type of information involved (shared...

This paper uses a bivariate probit model to analyze firms' decisions to impose regimes of exclusive dealing and/or exclusive territories with their distributors. We employ a panel data set of manufacturing firms (from 1990 to 2005) that contains information about such vertical restraints. Firms...

In this paper, we discuss the case of the integration between NSK and Amatsuji Steel Ball by using the successive oligopoly model. We show that the integration does not lead to input foreclosure. However, it leads to customer foreclosure, if the fixed cost of a rival firm in the upstream market...
