Productive efficiency and ownership when market restructuring affects production technologies
Cullmann, Astrid; Nieswand, Maria; Rechlitz, Julia - 2017
While the link between the ownership and productive efficiency of firms has been discussed extensively, no consensus exists regarding the superiority of one or the other in non-competitive, regulated environments. This paper applies a flexible production model to test for efficiency differences...

The impact of ownership unbundling on cost efficiency : empirical evidence from the New Zealand electricity distribution sector
Filippini, Massimo; Wetzel, Heike - 2013
Several countries around the world have introduced reforms to the electric power sector. One important element of these reforms is the introduction of an unbundling process, i.e., the separation of the competitive activities of supply and production from the monopole activity of transmission and...

Measuring productivity when technologies are heterogeneous : a semi-parametric approach for electricity generation
Seifert, Stefan - 2015
While productivity growth in electricity generation is associated with multiple positive effects from an economic and … environmental perspective, measuring it is challenging. This paper proposes a framework to estimate and decompose productivity … estimation based on stochastic non-smooth envelopment of data (StoNED) allows for productivity estimation with few microeconomic …

Network utilities performance and institutional quality : evidence from the Italian electricity sector
Soroush, Golnoush; Cambini, Carlo; Jamasb, Tooraj; … - 2020
It is generally accepted that institutions are important for economic development. However, whether the performance of regulated utilities within a country is affected by the quality of institutions is yet to be investigated thoroughly. We analyse how the quality of regional institutions impact...

Benchmarking and firm heterogeneity in electricity distribution : a latent class analysis of Germany
Cullmann, Astrid - 2009
In January 2009 Germany introduced incentive regulation for the electricity distribution sector based on results obtained from econometric and nonparametric benchmarking analysis. One main problem for the regulator in assigning the relative efficiency scores are unobserved firm-specific factors...

Semi-parametric measures of scale characteristics of German natural gas-fired electricity generation
Seifert, Stefan - 2016
Scale characteristics are key properties of production functions that determine optimal firm sizes, and have considerable policy implications for sectors undergoing restructuring. However, estimates of scale characteristics typically vary with the assumptions of the underlying empirical model....

Benchmarking heterogeneous distribution system operators : evidence from Norway
Elias, George - 2016
Regulatory authorities in the European electricity sector use benchmarking techniques to determine the cost-efficient production level for an incentive regulation of distribution system operators (DSOs). With nearly 900 DSOs operating in the German electricity sector, of which 200 subject to...

Unobserved technological heterogeneity among German electricity distribution network operators - a latent class analysis
Just, Lisa - 2021
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'...

Incentive regulation : evidence from German electricity networks
Hellwig, Michael; Schober, Dominik; Cabral, Luís M. B. - 2019 - This version: January 29, 2019
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...

Incentive regulation : evidence from German electricity networks
Hellwig, Michael; Schober, Dominik; Cabral, Luís M. B. - 2018
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) incur higher costs when subject to a lower-powered regulation mechanism. The...
