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....

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 growth for a sector characterized by multiple...

Mehr als 1600 Verteilnetzbetreiber versorgen deutsche Haushalte mit Strom und Gas. Dabei handelt es sich um »natürliche Monopole«, d.h. es gibt keinen direkten Wettbewerb zwischen den Unternehmen, sondern werden sie durch die Bundesnetzagentur im Anreizregulierungsverfahren reguliert....

Sustainable intensification measures promise ecological improvements of farming while maintaining profitability. That is, farms should be able to produce at a higher ecological efficiency without losses in economic efficiency. Based on a theoretical framework, we investigate this promise...

Efforts undertaken by France to restructure the allocation of governmental competencies increased the importance of subnational governments by transferring additional tasks. This paper analyzes the efficiency of public spending on an intermediate government level for a sample of 96 départements...

Benchmarking methods are widely used in the regulation of firms in network industries working under heterogeneous exogenous environments. In this paper we compare three recently developed estimators, namely conditional DEA (Daraio and Simar, 2005, 2007b), latent class SFA (Orea and Kumbhakar, 2004;...

In this paper, we analyze the technical efficiency of CO2 reduction potentials of German power and heat plants, using a non-parametric sequential Data Envelopment Analysis. We apply a metafrontier framework to evaluate plant-level efficiencies in the transformation of inputs into desirable...
