Different from traditional efficiency research and previous studies considering undesirable outputs, this paper proposes models which distinguish weak and strong disposability features among various undesirable outputs based on the technical nature of the undesirable outputs. The paper...

In theory, competitive electricity markets can provide incentives for efficient investment in generating capacity. We show that if consumers and investors are risk averse, investment is efficient only if investors in generating capacity can sign long-term contracts with consumers. Otherwise the...

I explore the advantages of tradable emission permits over uniform emission standards when the regulator has incomplete information on firms’ emissions and costs of production and abatement (e.g., air pollution in large cities). Because the regulator only observes each firm’s abatement...

Conditional on choosing a pegged exchange rate regime, what determines the currency to which countries peg or “anchor” their exchange rate? This paper aims to answer this question using a panel multinomial logit framework, covering more than 100 countries for the period 1980-1998. We find...

Beginning in 1995 a large proportion of the Brazilian electricity distribution sector went through privatisation and restructuring, whereas privately-owned U.S. utilities did not suffer similar ownership change process. This paper is an empirical assessment of the efficiency of the Brazilian...

This paper presents an analysis and defence of competition in retail electricity supply. It includes some account of its development in the UK over the last dozen years, to the point where all retail price controls have now been removed. The development of this competition illustrates a number...

Renewables require support policies to deliver the European 20% target. We discuss the requirements for least cost development and efficient operation and quantify how different schemes (i) allow for the development of a renewable energy technology portfolio; (ii) reduce rent transfers to...

The question this paper addresses is: what is the evidence for the superiority of the ownership unbundled transmission models (i.e. UK or Nord Pool hybrid) over other models? We assess the theoretical costs and benefits of ownership unbundling and judge these to be generally positive, though...

This paper presents an empirical analysis of the efficiency of the UK debt management authorities' (DMA) behaviour from a cost minimisation perspective over the period January 1985 to March 1995. During this period, the maturity structure of the government's bond portfolio was subject to...

Electricity reform has coincided with a significant decline in energy R&D activities. Technical progress is crucial for tackling many energy and environmental issues as well as for long-term efficiency improvement. This paper reviews the industrial organisation literature on innovation to...
