In this paper we study an oligopoly game with a differentiated product using a dynamic evolutionary approach. Firms are allowed to choose between quantity setting and price setting behavior. We find that, under both classical interaction structures, namely 'random mating' and 'paying the field'....

We study the regulation of a firm which supplies a regulated service while also operating in a competitive, unregulated sector. If the firm conducts its activities in the two markets jointly, it enjoys economies of scope whose size is the firm's private information, unknown either to the...

We examine the issue of whether two monopolists which produce substitutable goods should be regulated by one (centralization) or two (decentralization) regulatory authorities, when the regulator(s) can be partially captured by industry. Under full information, two decentralized agencies - each...

This paper develops the idea that industry regulation can be treated as a bargaining between a firm and the public authority, and illustrates some consequences of this formulation. The author investigates a typical regulatory problem where a firm chooses a cost-reducing investment before price...

This paper examines competition in a liberalized market, with reference to some key features of the natural gas industry. Each firm has a low (zero) marginal cost core capacity, due to long term contracts with take or pay obligations, and additional capacity at higher marginal costs. The market...

In this paper we review the recent liberalization process in energy markets promoted by the European Commission in the late Nineties and implemented in all the member countries. The electricity and gas industries are characterized by a predominant role of network infrastructures, and by upstream...

We analyse the effects of different regulatory schemes (price cap and profit sharing) on the endogenous size of a firm's investment. Using a real option approach in continuous time, we show that profit sharing does not delay a firm's start-up investment compared to a pure price-cap scheme....
