The theoretical discussion concerning the question whether the incumbent or the (potential) entrant invests more into R&D has attracted considerable interest. This paper reports the results of an empirical study on this question using data of about 3500 German firms over the years 1992 to 1995....

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 discusses the incentives for innovation when liability is limited or not. Clearly innovative activity involves risk. On the one hand, the risk of firm owners is limited if their liability is limited. On the other hand credits will be more difficult to receive if liability is limited....

A comprehensive descriptive analysis of gender wage differences over a long time period is missing for West Germany. Using an empirical approach which takes into account explicitely changes of wage distributions for both males and females as well as life-cycle and birth cohort effects, we go...

Die Bekämpfung der Arbeitslosigkeit genießt oberste wirtschaftspolitische Priorität - dieser Feststellung wird kaum jemand widersprechen wollen. Eher scheiden sich die Geister an der Frage nach dem "wirklichen" quantitativen Ausmaß der Unterbeschäftigung, ihren Ursachen und welche...

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...

This paper discusses theoretically the different incentives of managers versus firm owners to invest in innovative activities. There are opposing effects concerning R&D intensity in the manager-controlled firm. Our study on the determinants of R&D intensity presents empirical results concerning...

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...

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...
