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...

Investment and employment adjustment after unification : some results from a macroeconometric disequilibrium model

Radowski, Daniel; Smolny, Werner; Winker, Peter - 1999

The macroeconomic development in West Germany in the aftermath of unification was characterized by a boom period in 1990/1991, a deep recession in 1992/1993 and a slow recovery since then. In East Germany, in contrast, unification induced a breakdown of production and employment followed by a...

Modeling German unification in a disequilibrium framework

Winker, Peter; Smolny, Werner; Radowski, Daniel - 1999

Unification fundamentally changed the terms of quantitative macroeconomic analysis for Germany. Two main areas concerned are data availability for the eastern part of Germany and structural changes within the behavioural equations after unification. Our paper presents results from the estimation...

Intangible assets and investments at the sector level : empirical evidence for Germany

Crass, Dirk; Licht, Georg; Peters, Bettina - 2014

This paper investigates the role intangible capital plays for economic growth in different sectors in Germany. It … growth at the sector level by performing growth accounting analyses. We find that German firms have boosted investments in … sector trade & transport. Intangible assets have stimulated labour productivity growth in all sectors. The contribution …
