Any serious empirical study of factor substitutability has to allow the data to display complementarity as well as substitutability. The standard approach reflecting this idea is a translog specification – this is also the approach used by numerous studies analyzing the relative capital-skill...

This paper compares technologies across space and time on the basis of factual and counterfactual substitution elasticities and argues that differences in estimated substitution elasticities should be decomposed into two counterfactual components. While the first component is designed to...

Estimating the degree of substitution between energy and non-energy inputs is key for any evaluation of environmental and energy policies. Yet, given the large variety of substitution elasticities, the central question arises as to which measure would be most appropriate. Apparently, ALLEN's...

Die im Rahmen der Hartz-Reformen auf den Weg gebrachten Änderungen der Arbeitsmarktgesetzgebung haben die rasche und nachhaltige Vermittlung in Arbeit, die Schaffung neuer Beschäftigungsfelder und den Bau von mehr Brücken in Beschäftigung zum Ziel. Hauptziel ist letztlich die Verringerung...

This paper provides micro-econometric evidence on the effectiveness of Active Labor Market Policies (ALMP) in Poland. We sketch the theoretical framework of matching estimators as a substitute for randomization in labor market programs. Using retrospective data from the 18th wave of the Polish...

This paper provides a preliminary assessment of recent reforms of German employment promotion policy. While several recent studies analyze the impact of measures of employment promotion for the case of Germany, no comparable study exists on the aggregate level, thus precluding any assessment of...

Trotz des beachtlichen personellen und finanziellen Aufwands, der in der Bundesrepublik für die Durchführung arbeitsmarktpolitischer Maßnahmen betrieben wird, ist ihr Erfolg in keiner Weise gesichert. Im Gegenteil, die bisherige Evaluierungspraxis verletzt nahezu durchgängig eine der...

This paper estimates causal effects of two Polish active labor market policies – Training and Intervention Works – on employment probabilities. Using data from the 18th wave of the Polish Labor Force Survey we discuss three stages of an appropriately designed matching procedure and...

Each year Germany and many other developed economies spend tens of billions of Euros on active measures of employment promotion with the explicit aim of contributing to the reduction of unemployment. Yet, high unemployment has universally been a persistent problem throughout the last two...
