This paper investigates whether European electricity market refirms have induced any changes infirm efficiency either through productive, allocative or dynamic efficiency improve- ments. In particular, this ex-post analysis looks closely at productivity e ects of changing industry structure,...

This paper presents an ex-post empirical analysis of the impact of European electricity mar- ket refirms on markups ofirms. The working hypothesis is that further economic integration would bring competition into electricity markets re ected by lower markups of electricityfirms. The results show...

The capacity of the transmission network determines the extent of integration of a multinational energy market. Cross-border externalities render coordination of network maintenance and investments across countries valuable. Is it then optimal to collect powers in the hands of a single...

Der deutsche Strommarkt hat sich gut vom Krisenjahr 2022 erholt. Die Energiepolitik sollte sich nun wieder auf den Ausbau erneuerbarer Energien fokussieren. Das letzte Jahr hat gezeigt, dass die Stromversorgung auch nach Abschalten der Kernkraftwerke sicher ist. Den Stromverbrauch durch 80...

The German electricity market has recovered well from the 2022 energy crisis. Policymakers should now redirect the focus of energy policy to further expanding renewable energy sources. The year 2023 showed that the German electricity supply remained secure following the shutdown of nuclear power...

This paper examines the prices versus quantities issue, originally raised by Weitzman [8], in the context of carbon dioxide emissions and with a special focus on electricity generation. Within a simpli ed model of the electricity market, in which we explicitly allow for a monopolistic gas...

This article contributes to the debate of missing money (e.g. Joskow(2007)) which has seriously questioned the desirability of caps on scarcity prices in markets with fluctuating demand by emphasizing their potentially negative impact on firms investment decisions in the long run. A prominent...

This paper shows that generators exercised increasing market power in the England and Wales wholesale electricity market in the second half of the 1990s despite declining market concentration. It examines whether this was consistent with static, non-cooperative oligopoly models, which are widely...

Quality of service is of major economic significance in natural monopoly infrastructure industries and is increasingly addressed in regulatory schemes. However, this important aspect is generally not reflected in efficiency analysis of these industries. In this paper we present an efficiency...

We analyze the effects on social welfare of two different processes of transmission network expansion planning. A first model (integrated model) considers decisions on electricity generation and transmission as interdependent activities. A second model (disintegrated model) assumes that these...
