Empirical Tools for the Analysis of Technological Heterogeneity and Change. Some Basic Building Blocks of "Evolumetrics"

This paper is concerned with empirical approaches within the field of evolutionary economics. Evolutionary economics devotes special emphasis on the heterogeneity of actors with respect to their technological performance as well as to their inventive and innovative success. This causes major methodological problems which require appropriate measures and methods for their solution. This article attempts to introduce some tools which are able to measure and represent technological heterogeneity and its change and to investigate the determinants consistent with evolutionary theorizing. The tools suggested constitute basic building blocks of what may be called evolumetrics.
