This paper analyses the development of mobile telephony in France and Germany in 1998–2002. We conduct this analysis in relation to the antitrust investigation initiated by the French competition authority in 2002 due to exchange of strategic information and a share-fixing agreement between network operators. The results suggest a significant difference between price elasticities of demand in t...

We examine multilateral bargaining in vertical supply relationships which involve an upstream manufacturer who sells through two competing retailers to end consumers. In these relationships the negotiations are inter-dependent and a bargaining externality may arise across the retailers. In addition, the timing by which the manufacturer negotiates with the retailers becomes important. The manufa...

A well-studied problem in the literature on airline revenue (or yield) management is the optimal allocation of seat inventory among fare classes given a demand distribution for each class. In practice, the seat allocation decisions of one airline affect the passenger demands for seats on other airlines. In this paper we examine the seat inventory control problem under both horizontal competitio...

We study the static and dynamic implications of non-linear pricing schemes (i.e., bundling) for otherwise unrelated products but for multimarket contact. Bundling is always present in competition but unlikely in a cartel agreement. Although it brings extra profits to the cartel –sometimes charging a premium rather than a discount for the bundle–, bundling makes deviation from the agreement far ...

Almost all businesses are involved in complex business processes including negotiation. To enter into a negotiation process, the protocol or rules of negotiation need to be established. In the negotiation mechanism, the negotiation protocol is one of the main issues in binding an agreement. This paper investigates the monotonic concession protocol, which is difficult to utilize in an automated ...

This paper presents a model of competition between an incumbent firm and an Other Licensed Operator (OLO) in the broadband market, where the incumbent has an investment option to build a Next Generation network (NGN) and it can do so by making an investment sharing agreement with the OLO, or alone. Two different kinds of investment sharing contractual forms are analysed, a basic investment shar...

In this paper we introduce mutual mobile membranes with surface objects, systems which have biological motivation. In P systems with mobile membranes with surface objects, a membrane may enter or exit another membrane. The second membrane just undergoes the action, meaning that it has no control on when the movement takes place. This kind of movement illustrates the lack of an agreement (synchr...
