Demsetz (1968) advocated competitive bidding as a replacement for natural monopoly regulation. Williamson (1976) and Goldberg (1976) argued that these problems of natural monopoly regulation are inherent in long-term investment under uncertainty, and that both long- and short-term franchising...

Electricity transmission has emerged as critical for successfully liberalising power markets. This paper surveys the issues currently under discussion and provides a framework for the remaining papers in this issue. We conclude that signalling the efficient location of generation investment...

In this paper we describe the Spanish electricity industry and its current regulatory regime. Special emphasis is given to the description and discussion of market design issues (including stranded cost recovery), the evolution of market structure, investment in generation capacity and network...

It is difficult to elminated all market power in electricity markets and it is therefore frequently suggested that some market power should be tolerated: extra revenues contribute to fixed cost recovery, facilitate investment and increase security of supply. This suggestion implicitly assumes...

Should regulation of potentially competitive elements of network utilities be left with sector regulators or solely subject to normal competition laws? Britain evolved licenses for network activities overseen by regulators while the EU places more emphasis on making sector regulation consistent...

The UK utility regulation framework developed in the 1980s was intended to improve on the restrictive, inefficient and burdensome regulatory approach in the US. But the UK regulatory process has itself now become increasingly burdensome. Meanwhile, utilities and customer groups in the US and...

Merchant electricity transmission investment is a practically relevant example of an unregulated investment with monopoly properties. However, while leaving the investment decision to the market, the regulator may decide to prohibit capacity withholding with a must-offer provision. This paper...

This paper provides an overview of the development of electric power transmission access, pricing and investment policies in the U.S. over the last 15 years and evaluates the current state of those policies. It includes a discussion of pre-liberalisation transmission access and pricing policies,...

In this paper we study concentration in the European Internet upstream access market. Measurement of market concentration depends on correctly defining the market, but this is not always possible as Antitrust authorities often lack reliable pricing and traffic data. We present an alternative...

Concern over mobile termination charges under Calling Party Pays (CPP) has led to severe price controls on termination charges. These are of limited effectiveness in aligning termination charges with costs, net welfare gains from controls are small and costs of setting controls are high....
