This paper applies parametric and non-parametric and parametric tests to assess the efficiency of electricity distribution companies in Germany. We address traditional issues in electricity sector benchmarking, such as the role of scale effects and optimal utility size, as well as new evidence...

Accounting for network operators' heterogeneity is of crucial importance for regulators. In contrast to observed heterogeneity, the consideration of unobserved differences is far more challenging. Most estimation models try to account for unobserved factors that impact the network operators'...

This research presents an application of the Hogan, Rosellón and Vogelsang (2010) (HRV) mechanism to promote electricity transmission network expansion in the Peruvian electricity transmission system known as SEIN (Sistema Eléctrico Interconectado Nacional). The HRV mechanism combines the...

In this paper we report the findings of an experiment that examines the effects of automated mitigation procedures (AMP) on capacity investment prices of suppliers in a wholesale electricity market. Specifically, in a 2 x 2 design we examine the effects of strong and weak market power incentives...

This paper evaluates four publicly discussed policy options to mitigate market power in the German wholesale electricity market. These four options are: a regulatory solution favoured by the Federal Ministry for Economics and Technology, the implementation of a day-ahead flow-based market...

Abstract: This paper analyzes the impact of deregulation and restructuring on public-interest environmental research conducted by electric utilities in the US for the period 1990-2001. I find that deregulation has had a tremendous negative on such expenditures which have declined by 40 percent....

Energy efficiency provides a substantial opportunity to tackle increasing greenhouse gas emissions. However, in traditionally regulated energy markets, energy providers maximize their profits by selling electricity or heat as long as their marginal revenue exceeds their marginal costs of...

This study uses a Cox proportional hazards model to analyze changes in the risk of unplanned outages in U.S. nuclear power plants after the Three Mile Island (TMI) accident. The unplanned outage hazard is related to safety by the fact that most such outages begin with unplanned reactor scrams....
