Efficiency measurement naturally requires the definition of a frontier as a benchmark indicating efficiency. Usually a measure reflecting the distance of a data point to the frontier indicates the level of efficiency. One of the crucial characteristics to distinguish efficiency measurement tools...

In this position paper we deal with the conception of heterogeneity as both the force and the result of evolutionary change. We ask, how this heterogeneity can be measured empirically and how we can get a measure which allows to get a broad comparable empirical account especially on several...

In this paper we add new results to the emerging field of investigating productivity levels rather than productivity change, as initiated by Hall and Jones (1996, 1997). To obtain measures of relative productivity levels we depart from traditional growth accounting and calculate the Malmquist...

The objective of this paper is twofold. First we discuss, whether data envelopment analysis can be applied to households' consumption activities on the basis of Kelvin Lancaster's approach to consumer choice. Then, we apply data envelopment analysis to identify inefficiencies in a subsector of...

This paper reviews empirical and theoretical work concerning the relationship between innovative activities of firms and the dynamics of industries. Stylized facts on industry evolution and the analysis of industrial dynamics in general are a first building block. This discussion just reflects a...

Zusammenfassung In der vorliegenden Studie wird mit Hilfe der nicht-parametrischen DEA-Methode die relative Effizienz von representativ ausgewählten Stromversorgungsunternehmen in Deutschland bestimmt. Die DEA erlaubt es, auch nicht marktfähige In- und Outputfaktoren in die Analyse...

Summary In this paper we add new results to the investigation of productivity levels rather than productivity changes, as proposed by Hall/Jones (1996, 1997, 1999). To obtain measures of relative productivity levels we depart from traditional growth accounting and calculate the Malmquist index...
