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...

In this paper I set forth an antitrust remedy for the oligopolistic pricing problem. Oligopoly pricing resembles a repeated prisoners' dilemma game. Each firm has an incentive to moderately lower its price and thus increase its sales at its competitors' expense. However, each firm knows that its...

We review the Economics literature on newspapers and magazines. Our emphasis is on the newspaper industry, especially in the United States, given that this has been the focus of existing research. We first discuss the structure of print media markets, describing the rise in the number of daily...

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...

The paper develops a framework for Internet backbone competition. In the absence of direct payments between websites and consumers, the access charge allocates communication costs between websites and consumers and affects the volume of traffic. The paper analyzes the impact of the access charge...

The anomalous inverse concentration-price relationship observed by some researchers in the newspaper market has been attributed to scale economies. In this paper we suggest that the newspaper's (or magazine's) double-product feature (i.e., news supplied to readers and advertising space supplied...

We analyze the effect of different pricing schemes on horizontally differentiated firms' ability to sustain collusion when customers have the possibility to combine (or mix) products to achieve a better match of their preferences. To this end, we compare two-part tariffs with linear prices and...

This paper examines the competitive effects of resale price maintenance (RPM) through inventory decisions under demand uncertainty. We focus on the Japanese publishing industry where RPM is allowed. We develop and estimate a model of RPM in which price and inventory are determined before demand...

We investigate the effect of a ban on third-degree price discrimination on the sustainability of collusion. We build a model with two firms that may be able to discriminate between two consumer groups. Two cases are analyzed: (i) Best-response symmetries so that profits in the static Nash...

We demonstrate that cost pass-through can be used to inform demand calibration, potentially eliminating the need for data on margins, diversion, or both. We derive the relationship between cost pass-through and consumer demand using a general oligopoly model of Nash-Bertrand competition and...
