This paper describes an incentive mechanism that is shown to enforce the use of Ramsey prices by multiproduct monopolies. The constraint given is simple. It limits information requirements on the regulatory agency to bookkeeping data of the firm. Its implementation could be easily controlled by...

Without access of networks to each other, competition in the telecommunications sector would hardly have spread so quickly. Such mutual access is necessary for carriers to provide ubiquitous service and enable end-users to call and be called by anybody without subscribing to a system-wide...

The main results of the sustainability literature on natural monopolies (for example, Panzar and Willig (1977)), are shown to depend on the Bertrand conjecture. First, for the natural monopoly case we prove that industry configurations that are sustainable in the sense of Willig (1980) are...

Regulation and consumer class actions can complement, duplicate, or oppose each other, depending, among others, on the leanings of regulatory objective functions towards the industry or consumers. In particular, pro-consumer regulators would like to see consumers benefit from class actions while...

This paper considers methods of price structure regulation of electricity transmission in the context of an independent transmission company (TRANSCO). The focus is on two-part tariffs where the variable part would reflect congestion charges (and ancillary services) while the fixed part would...

The dramatic worldwide increase in mobile communication that has led to more than 4 billion users has over the last few years been accompanied in wealthy countries by a significant decline in fixed network subscriptions. Such fixed-to-mobile substitution (FMS) is at the center of this literature...

Electricity transmission pricing and transmission grid expansion have received increasing regulatory and analytical attention in recent years. Since electricity transmission is a very special service with unusual characteristics, such as loop flows, the approaches have been largely tailor-made...

Electricity transmission has become the pivotal industry segment for electricity restructuring. Yet, little is known about the shape of transmission cost functions. Reasons for this can be a lack of consensus about the definition of transmission output and the complexitity of the relationship...
