Effective competition in wholesale electricity markets is the cornerstone of the deregulation of the electricity generation industry. We examine the degree of competition in the California wholesale electricity market during June-November 1998 by comparing the market prices with estimates of the...

As with other commodities, electricity is often traded on both forward and spot markets. This was initially true in the restructured California electricity ndustry from 1998 to 2000. Though the power traded in the forward and spot markets was for delivery at the same times and locations, prices...

Advocates of using market mechanisms for addressing greenhouse gases and other pollutants typically argue that it is a necessary step in pricing polluting goods at their social marginal cost (SMC). Retail electricity prices, however, deviate from social marginal cost for many reasons. Some cause...

We study price convergence between the two major markets for wholesale electricity in California from their deregulation in April 1998 through November 2000, nearly the end of trading in one market. We would expect profit-maximizing traders to have eliminated persistent price differences between...

In an unregulated electricity generation market, the degree to which generators in" different locations compete with one another depends on the capacity to transmit electricity" between the locations. We study the impact of transmission capacity on competition among" generators. We show that...

We use demand and plant-level cost data to simulate competition in a restructured California electricity market. This approach recognizes that firms might have an incentive to restrict output in order to raise price and enables us to explicitly analyze each firm's ability to do so. We find that,...
