In the following we propose a growth model for an economy consisting of firms which are heterogeneous in technologies and input demands. We show that the growth rate in this economy depends not only on changes in the aggregate level of capital and labor, but also on changes in the allocation of...

This paper studies the productivity impact of heterogeneous capital inputs of selected EU-15 member countries and of the U.S. at the macroeconomic level. The stochastic possibility frontiers approach of Battese and Coelli (1992) applied here is used to identify neutralities or non-neutralities...

Trotz der breit angelegten Digitalisierung sind die Produktivitätsfortschritte in Deutschland in den letzten Jahren erheblich niedriger als in den vorhergehenden Dekaden. Eine Wachstumszerlegung weist auf stark nachlassende Impulse des Technischen Fortschritts und vor allem der Kapitalbildung...

From an engineering perspective, a capital good's service is energy conversion - e.g., the physical 'work' done by a machine - and can thus be measured directly by the energy consumed in production. We show important empirical advantages of our concept over traditional measures. The empirical...

This study deals with the determinants of factor demand in 27 industries of the manufacturing sector during the period 1978 to 1990. Using a quadratic cost function, six production factors are distinguished : capital, energy, three types of labour and intermediate materials. A parametric test of...

In this paper, substitutional relationships between capital, labour, material, electricity, and fossil fuels in German producing and service sectors are estimated using a translog cost function. Estimates are based on a pooled time-series cross-sectional data sample for the period 1978-90 and...
