In this paper, four commonly provided explanations for the shift in labour demand for different skill groups are investigated: the substitutability of inputs; the own-price sensitivity for different types of labour; the effect of economic growth and the impact of technological change. In...

The paper analyses the theoretical and empirical relationship between employment, skill structure and innovation in East and West German manufacturing firms. The econometric part builds on firm data from the Mannheim Innovation Panel 1993, 1994 and 1995. In the German industrial sector,...

We analyze the economic factors which have contributed to the dramatic decline of the employment share of unskilled labor in German manufacturing, in particular the role played by the relatively rigid earnings structure. Potential effects of intensified international competition and skillbiased...

We analyze the dramatic decline of the employment share of unskilled labor in the West German economy, in particular its relation to the relatively rigid earnings structure. We find that the substitution elasticity between unskilled and skilled labor is rather low in most sectors of the economy....

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...

This paper examines the effects that purchased services and imported intermediate materials have on the labour demand for different skills in the manufacturing sector. We derive and estimate a factor demand system based on the generalised Box-Cox cost function nesting both the normalised...

Any serious empirical study of factor substitutability has to allow the data to display complementarity as well as substitutability. The standard approach reflecting this idea is a translog specification - this is also the approach used by numerous studies analyzing the relative capital-skill...
