Ein Jahr nach Inkrafttreten der deutschen Energierechtsnovelle sind die Konturen der zukünftigen Strommarktregulierung noch zu weiten Teilen ungeklärt. Vor diesem aktuellen wirtschaftspolitischem Hintergrund wird in diesem Papier die Frage nach einer sachgerechten Ausrichtung der...

In this paper, we present a standard quality ladders endogenous growth model with one significant new assumption, that it takes time for firms to learn how to export. We show that this model without Melitz-type assumptions can account for all the evidence that the Melitz (2003) model was...

We develop an endogenous growth model which is focussed on entrepreneurial skills and their impact on growth and convergence. Our work is closely related to the model by Acemoglu et al. (2006) but extends their analysis in some important respects. Entrepreneurs in our model dispose of two...

How do labour market policies influence employment's responsiveness to output fluctuations (employment-output elasticity)? We revisit this question on a panel of OECD countries, which also incorporates the period of the Great Recession. We distinguish between passive and active labour market...

This paper analyses how and to which degree the Danish flexicurity concept and its various elements achieve the renowned Danish miracle by evaluating their unemployment and inequality effects and their complementarities. We develop a microfounded model of searching workers and firms, calibrate...

When in-store display influences consumer choices, shelf space allocation can be strategically used by retailers to extract payments from manufacturers. The paper finds that manufacturers with better brand names have higher willingness-to-pay for shelf spaces. Shelf space fees soften inter-brand...

Die internationale Diskussion der letzten Jahrzehnte hat zur Frage nach einer effizienten Gestaltung der Einkommenssicherung von Arbeitslosen eine Reihe von Vorschlägen hervorgebracht, wie die von Beenstock/Brasse, Feldstein /Altman, Grubel und Orzag/Snower. Sie werden dargestellt und bewertet....

We develop a nonparametric instrumental variable approach for the estimation of average treatment effects on hazard rates and conditional survival probabilities, without model structure.We derive constructive identification proofs for average treatment effects under noncompliance and dynamic...

Firms select not only how many, but also which workers to hire. Yet, in standard search models of the labor market, all workers have the same probability of being hired. We argue that selective hiring crucially affects welfare analysis. Our model is isomorphic to a search model under random...

Based on a standard idea-based model of endogenous growth we test the hypothesis that regional innovative activity is path-dependent, and investigate the geographical scope of knowledge spillovers. Using data for West-German regions, two alternative indicators of the stock of knowledge are...
