Curvature conditions and substitution pattern among capital, energy, materials and heterogeneous labour

Falk, Martin; Koebel, Bertrand M. - 1999

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...

A dynamic heterogeneous labour demand model for German manufacturing

Falk, Martin; Koebel, Bertrand M. - 2000

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...

Imposing and testing curvature conditions on a Box-Cox function

Koebel, Bertrand M.; Falk, Martin; Laisney, François - 2000

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...

Organizational change, new information and communication technologies and the demand for labor in services

Falk, Martin - 2001

of the introduction of information and communication technology (ICT) on actual labor demand as well as on employment … multivariate probit models. The empirical results suggest that OC has a positive effect on actual employment growth given output … and factor price changes. Furthermore, we find that organizational change has a positive impact on expected employment for …
