Angesichts des demographischen Wandels gewinnen die Verlängerung der Erwerbstätigkeit und damit auch die Bedingungen für Neueinstellungen im letzten Drittel des Erwerbslebens an Bedeutung. Dieser Beitrag untersucht auf mikroökonomischer Grundlage (IABBetriebspanel) betriebliche Merkmale, die...

We use a linked employer-employee data set from Germany to estimate the wage effect of foreign-affiliates in East and West Germany. In addition, the wage effects of the large number of West German affiliates which are located in East Germany are also considered. The implemented techniques allow...

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...

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...

Although works councils are a core element of the German system of industrial relations, there is little reliable information on their incidence and coverage. This paper uses data from the nationally representative IAB establishment panel to fill this gap. We examine the frequency of works...
