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...

This paper analyses whether wages in Germany respond to firm-specific profitability conditions. Particular emphasis lies on the question of whether the extent of rent-sharing varies across different systems of wage determination. Those may be categorised into sector-specific wage agreements,...

This paper studies whether the transition from a centrally planned to a market economy offers new perspectives for those who, in economic terms, were relatively deprived under the old regime. Previous empirical research on this question has been limited by the availability of representative...

Using a linked employer-employee data set, this paper analyses the relationship between firm profitability and wages. Particular emphasis is given to the question of whether the sensitivity of wages to firm-specific rents varies with collective bargaining coverage. To address this issue, we...

Using a linked employer-employee data set, this paper analyses the relationship between firm-profitability and wages. Particular emphasis is given to the question of whether the sensitivity of wages to firm-specific rents varies with collective bargaining coverage. To address this issue, we...

The paper investigates whether (unsubsidised) fixed-term contracts (FTCs) are a means of integration for the unemployed in the West German labour market. This is done by analysing whether entering into an FTC improves the employment opportunities of an unemployed person in terms of the...

Ob und wie lange Jugendliche nach Abschluß ihrer Lehre weiterhin im Ausbildungsbetrieb arbeiten, ist eine Fragestellung, deren Beantwortung für das Verständnis des Arbeitsmarktes in mehrfacher Hinsicht von Nutzen sein kann. Zum einen liefern Abgänge aus dem Ausbildungsbetrieb ohne...

This study provides empirical evidence for the economic rationality of wage rigidities. Theoretically wage rigidities can result from contracts, implicit contracts, from efficiency wages and from insider-outsider behaviour. Based on a survey of 801 firms strong support has been found for...

Aufbauend auf der Hypothese, dass Arbeitsmärkte durch unvollständige Information charakterisiert sind, werden in diesem Arbeitspapier neuere Entwicklungen innerhalb eines Zweiges informationsökonomischer Ansätze vorgestellt: der Suchtheorie. Dabei werden ausführlich insbesondere jene...

There is a growing concern about collective wage agreement and employment dynamics in Germany. In this paper, evidence is provided on the way collective wage agreements affect the adjustment of working hours, employment and other production factors when firms from the service sector are faced...
