R&D cooperation is reconsidered in situations where firms direct R&D activities towards a new product that cannibalizes the firms' existing products. For soft cannibalization, the welfare-maximizing arrangement between firms involves, for low R&D costs, the formation of a separate entity that...

Our companion article developed a clear conceptual framework of negotiated or regulated interconnection agreements between rival operators and studied competition between interconnected networks, under the assumption of non-discriminatory pricing. This article relaxes this assumption and allows...

Effectiveness in the use of the work force is often the crucial advantage in a company's long-term success over its competitors, especially in technology driven and highly competitive branches as the one considered in this article. While employee scheduling and rostering has been the topic of...

Assignment type problems consist in optimally assigning or allocating a given set of "activities" to a given set of "resources". Optimisation problems of the assignment type have numerous applications in production planning and logistics. A popular approach to solve such problems or to compute...

In combinatorial auctions the pricing problem is of main concern since it is the means by which the auctioneer signals the result of the auction to the participants. In order for the auction to be regarded as fair among the various participants the price signals should be such that a participant...

In general scheduling a sports league is a difficult combinatorial optimization problem. We study some variants of round robin tournaments and analyze the relationship with the planar three index assignment problem. The complexity of scheduling a round robin tournaments is settled by a reduction...

Generally speaking in sports competition a number of teams play against each other over a period of time according to a certain scheme. The round robin scheme is very popular in many team sports like soccer and basketball. In this paper we study several basic variants of round robin tournaments....
