Prior to the 1990s, most electricity customers in the U.S. were served by regulated, vertically-integrated, monopoly utilities that handled electricity generation, transmission, local distribution and billing/collections. Regulators set retail electricity prices to allow the utility to recover...

We analyze the demand for emissions allowances and the supply of allowances and abatement opportunities in California's 2013-2020 cap and trade market for greenhouse gases (GHG). We estimate a cointegrated vector autoregression for the main drivers of greenhouse gas emissions using annual data...

The wave of electricity market restructuring both within the United States and abroad has brought the issue of horizontal market power to the forefront of energy policy. Traditionally, estimation and prediction of market power has relied heavily on concentration measures. In this paper, we...

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,...

Effective competition in wholesale electricity markets is a necessary feature of a successful electricity supply industry restructuring. We examine the degree of competition in the California wholesale electricity market during the period June 1998 to September 1999 by comparing the market...

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...
