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....

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....

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...
