In this paper we investigate the determinants of local governments' technical efficiency in road maintenance for a panel of German counties using a broad variety of estimation approaches. More specifically, we calculate efficiency indices using non-parametric (DEA) and parametric (stochastic...

Ownership unbundling and third party access are discussed as two options of unbundling in both the literature and political discussions. Focusing on the South American electricity sector, I contrast static and dynamic impacts of ownership unbundling and third party access regimes on customer...

We analyze the treatment and impact of idiosyncratic or firm-specific risk in regulation. Regulatory authorities regularly ignore firm-specific characteristics, such as size or asset ages, implying different risk exposure in incentive regulation. In contrast, it is common to apply only a single...

The German response to the Fukushima nuclear power plant incident was possibly the most significant change of policy towards nuclear power outside Japan, leading to a sudden and very significant shift in the underlying power generation structure in Germany. This provides a very useful natural...

The harmonization and integration of separate national energy markets to an interconnected internal European market is a top priority of the European Commission. However, as energy policy largely remains subject to national sovereignty, a higher degree of integration can cause unilateral...

We propose a difference-in-differences (DiD) approach to estimate the impact of incentives on cost reduction. We show theoretically, and estimate empirically, that German electricity distribution system operators (DSOs) pile up more costs in the year used to determine future prices when subject...

Unbundling of vertically integrated utilities has become an integral element in the regulation of network industries and has been implemented in many jurisdictions. The idea of separating the network, as the natural monopoly, from downstream retailing, which may be exposed to competition, is...
