Overcoming data limitations in nonparametric benchmarking: applying PCA-DEA to natural gas transmission
Nieswand, Maria; Cullmann, Astrid; Neumann, Anne - 2009
of limited data availability in some regulated industries. Here, traditional DEA may result in a lack of discriminatory … power when high numbers of variables but only limited observations are available. We apply PCA-DEA for radial efficiency … while maintaining most of the variation in the original data. Our results suggest that the PCA-DEA methodology reduces the …

Technological change and transition: relative contributions to worldwide growth during the 1990s
Badunenko, Oleg; Henderson, Daniel J.; Zelenyuk, Valentin - 2007
In this paper we used the procedures developed in the Kumar and Russell (2002) growth-accounting study to examine cross-country growth during the 1990's. Using a data set comprising developed, newly industrialized, developing and transitional economies, we decomposed the growth of output per...

Second-best analysis of European energy policy: Is one bird in the hand worth two in the bush?
Hübler, Michael; Schenker, Oliver; Fischer, Carolyn - 2015
This paper studies policy instruments that correct insufficient learning-by-doing (LbD) and research and development (R&D) of renewable electricity technologies and insufficient investments in energy efficiency (EE) in the presence of carbon pricing. The theoretical model analysis shows how to...

Finding the right yardstick: Regulation under heterogeneous environments
Bjørndal, Endre; Bjørndal, Mette; Cullmann, Astrid; … - 2016
Revenue cap regulation is often combined with systematic benchmarking to reveal the managerial inefficiencies when regulating natural monopolies. One example is the European energy sector, where benchmarking methods are based on actual cost data, which are influenced by managerial inefficiency...

Incentive regulation: Evidence from German electricity networks
Hellwig, Michael; Schober, Dominik; Cabral, Luís - 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...

Key parameters and efficiency of Mexican manufacturing: Are there still differences between the north and the south? An application of nested and stochastic frontier panel data mod...
Braun, Frauke G.; Cullmann, Astrid - 2008
This study explores the prevalence and nature of the regional divide for the Mexican manufacturing production across sub-national regions. We utilize a unique panel of municipality-level data from the manufacturing sector. An important contribution is the use of different panel methods to...
