Most of the literature on price discrimination in input markets has focused on linear per-unit prices used by a monopolist supplier. Here, we provide a complete characterization of the equilibrium two-part tariffs, which can allow the monopolist supplier to obtain (at a minimum) the profit that...

This paper investigates optimal licensing in a mixed oligopoly with a foreign firm. It is the first to compare licensing by means of a fixed fee and by means of a royalty when the innovator is a public firm. In contrast to a private oligopoly, we show that license via a fixed fee is superior to...

In this paper we analyze firms' ability to tacitly collude on prices in software markets. We show that network externality hinders collusion. We also show that firms collude if they value future profits sufficiently.

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...

This note shows that the pro-competitive effect of pre-commitments is robust to Stackelberg-like market structures. Although our results are in line with Allaz and Vila (1993), the two equilibria differ substantially. Sequential interactions foster a monopolization of the contract market and a...

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...

The unidirectional Hotelling model where consumers can buy only from firms located on their right (left) is extended to allow for price discriminating firms and a general class of transportation costs. In a two-stage location-price game one firm locates at 1/2 and the other locates at 1 (0). We...

In a supplementary note to Ghosh and Morita ("Social desirability of free entry: a bilateral oligopoly analysis," 2007, IJIO), an example has been used to show that the condition for insufficient entry holds under the right-to-manage model of a vertically related industry. Using a linear demand...

This note shows that the profitability of a merger between a leader and a follower in a Stackelberg market crucially depends on the degree of collusion among leaders. When leaders cut production in order to raise the price, followers have lower incentives to merge with the leaders since by...

Shaffer (1991) shows that a multiproduct monopolist selling differentiated products through a unique retailer cannot earn monopoly profit using brand specific two-part tariffs and that full-line forcing restores monopoly power. We extend this analysis to more general contracts and shows that...
