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...

This paper presents an application of the Generalised Error Correction Model (GECM) for heterogeneous factor demands based on the quadratic cost function. Using data for 26 West German manufacturing industries over the period 1976-1995, it turns out that less general specifications such as the...

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...

We present a new method for imposing and testing concavity of a cost function using asymptotic least squares, which can easily be implemented even for cost functions which are nonlinear in parameters. We provide an illustration on the basis of a (generalized) Box-Cox cost function with six...

Birth rates differ strongly across European states, https://madoc.bib.uni-mannheim.de/55902despite the deep economic harmonisation process related to European integration. This study uses large scale administrative data from France and Germany to analyse and directly compare fertility patterns...

Many studies of producer behavior consider cost and input demand functions de-rived from microeconomic theory and estimate them on the basis of aggregate data. If firms' characteristics differs, the neglect heterogeneity can lead to estimation bias. An alternative is to restrict individual...

This paper analyses the link between technological product and processes innovations and expectations about future employment for different types of labour in manufacturing. The empirical model allows for endogeneity of the firm's innovation decision in the labour demand equations. The system of...

Between 1993 and 1995, the majority of German firms in services introduced new organizational practices (OC), in particular total quality management systems, certified ISO 9000, lean administration, flatter hierarchies, delegation of authority and ICT-enabled organizational changes). This paper...

This paper provides empirical evidence on both the magnitude and determinants of unfilled positions for information technology workers using cross-sectional data on 4150 German firms. Vacancies are defined as unfilled positions excluding those created by replacement needs during the first half...

This paper analyzes the link between the diffusion of information- and communication technology (ICT) and both the skill structure and employment expectations of the different skill categories. The analysis is based on cross-sectional data for 4150 German firms conducted in mid-2000. The...
