In this paper we analyse whether collusion exists in the Dutch waste collection market, which shows a high degree of concentration. Although scale effects might be in accordance with this market outcome, the question is whether this concentration is in fact a result of fair competition. Using...

We discuss the case of a monopolist of a base good in the presence of complementary goods provided either by it or by other firms. We assess and calibrate the extent of the influence on the profits from the base good that is created by the existence of complementary goods, i.e., the extent of...

Previous literature has mostly considered R&D and licensing activities separately. In this paper we examine the effect of licensing on R&D and social welfare. We show that the effect of licensing on the incentive for doing R&D is ambiguous and depends on the costs of doing R&D. We also show that...

We apply an indirect method to test for the extent of loss leader pricing. Specifically, the extent of loss leader pricing should increase with the profit from other regularly-priced items. Bookstores customarily use bestsellers as loss leaders. Among conventional bookstores, we found that the...

The operating areas of each terrestrial broadcasting station in Japan are geographically divided by a licensing system and form oligopolies in each of their respective markets. These institutional constraints define the market structure, and as a result, affect the business performance of the...

We empirically test some implications from location theory using the location of Los Angeles area gasoline stations in physical space and in the space of product attributes. We consider the effect of demand patterns, entry costs, and several proxies for competition -- the total number of...

This paper examines how the option for licensing affects research and development (R&D) and social welfare. We find that if cost reduction from R&D is sufficiently small and there is an option of licensing, firms will do non-cooperative R&D. In absence of licensing, firms will do cooperative R&D...

Coordination Failure Diagnostics (CFD) is a model that analyses real market processes with the help of time pattern analysis and investigates whether they operate efficiently (See www.wiwi.uni-muenster.de/cfd). The CFD cartel-audit should enable the detection of cartels via characteristic market...

This paper analyzes if vertical foreclosure can emerge as an equilibrium outcome of an infinitely repeated game. Foreclosure is profitable due to a 'raising rival's costs' effect but it is not a Nash equilibrium of the static game. The results are that foreclosure is in fact a subgame perfect...

Recent developments in information technology (IT) have resulted in the collection of a vast amount of customer specific data. As the IT advances the quality of such information improves. We analyze a sequential spatial model of oligopolistic third degree price discrimination where the firms use...
