The restructured market for electricity in the UK has experienced a systematic pattern of price spikes associated with the use of market power by the two dominant generators. Partly in response to this problem, the share of capacity owned by any individual generator after restructuring was limited in Victoria, Australia. As a result, a much more competitive market resulted with prices substanti...

NON TECHNICAL SUMMARY Background In the UK, over 400,000 people aged 65 and over receive long-term care in a care home, and this is projected to more than double over the next 50 years. Local authorities purchase care home places on behalf of a large group of people based on a means test of their income and capital assets. People excluded by the means test are self-funding. The care home market...

This paper applies a model of market power measurement under product differentiation to the case of the gasoline market in California, using data for the period 1983-1989. Our results show that there is a considerable degree of product differentiation among major brands. This allows firms to exercise local market power over their own specific products, but there are also signals of an important...

In this article we report an experiment that examines how demand-side bidding can discipline generators in a market for electric power. First we develop a treatment without demand-side bidding; two large firms are allocated baseload and intermediate cost generators such that either firm might unilaterally withhold the capacity of its intermediate cost generators from the market to benefit from ...

This paper measures the unilateral incentive each of the five largest electricity suppliers in the California had to exercise market power in the state’s wholesale market during the five month period June 1 to September 30 of 1998, 1999 and 2000. Using the actual bids submitted to the California Independent System Operator’s (CAISO) real-time energy market, I compute the hourly price elasticity...

Motivated by the extremely high prices for wholesale electricity in California from May, 2000 to June, 2001, this paper presents the results from four economics experiments using both industry professionals and students who compete to sell electricity in a simulated market. The market structure in the first three experiments parallels the design of the California market over time: a uniform pri...
