    Nobelpreis für Wirtschaftswissenschaften 2006 an Edmund S. Phelps
    (2006) Polleit, Thorsten; Geisslreither, Kai; Belke, Ansgar
    Am 9. Oktober dieses Jahres gab die Königlich Schwedische Akademie der Wissenschaften (KVA) bekannt, dass der Ökonom Edmund S. Phelps mit dem Wirtschaftsnobelpreis ausgezeichnet wird. Der vorliegende Beitrag stellt die wissenschaftlichen Leistungen von Phelps vor und ordnet sie in den makroökonomischen Gesamtkontext ein. Phelps? Arbeiten haben signifikant zur Verbesserung der Theorie des makroökonomischen Politik-Designs beigetragen. Von ihm ging die Idee einer um Erwartungen modifizierten Phillips-Kurve aus; diese trug dazu bei, den Konflikt zwischen Inflation und Beschäftigung als ?Scheinkonflikt? zu entlarven. Phelps lieferte somit einen bedeutenden Beitrag für die Mikrofundierung der Makroökonomik. Phelps? zweite bedeutende makroökonomische Innovation war die Entdeckung der goldenen Regel der Kapitalakkumulation. Auch sie birgt wichtige Politikimplikationen. Die Auszeichnung von Edmund S. Phelps ist ein folgerichtiger Schritt zur Würdigung eines Ökonomen, der die moderne Makroökonomik in umfassender Weise geprägt hat.

    Perspectives of workers with low qualifications in Germany under the pressures of globalization and technical progress
    (2007) Rukwid, Ralf; Hagemann, Harald
    This paper gives a detailed analysis of the perspectives of workers with low qualifications in Germany under the twofold pressures of globalization and technological change. First, alternative explanations for the skill-bias in the development of labour demand are discussed, with particular emphasis on the ?trade versus technology? debate. The consequences of the demand shift away from low-skilled labour in Germany are examined in a detailed empirical analysis of the development of (un)employment problems differentiated for qualification groups. Compared to other advanced economies, Germany shows a higher unemployment rate among less-qualified workers which is generally associated with a lack of flexibility in the German wage structure. However, an analysis of German, U.S. and British wage data based on the Cross National Equivalent File (CNEF) does not confirm the assumption of a simple monocausal relationship between wage disparity and the intensity of group-specific unemployment. Finally, some political approaches for an improvement of the job prospects of less-qualified persons in Germany are outlined briefly and evaluated against the background of the empirical results.

    Trade and unemployment : what do the data say?
    (2009) Felbermayr, Gabriel; Prat, Julien; Schmerer, Hans-Jörg
    This paper documents a robust empirical regularity: in the long-run, higher trade openness is causally associated to a lower structural rate of unemployment. We establish this fact using: (i) panel data from 20 OECD countries, (ii) cross-sectional data on a larger set of countries. The time structure of the panel data allows to deal with endogeneity concerns, whereas cross-sectional data make it possible to instrument openness by its geographical component. In both setups, we carefully purge the data from business cycle effects, include a host of institutional and geographical variables, and control for within-country trade. Our main finding is robust to various definitions of unemployment rates and openness measures. The preferred specification suggests that a 10 percent increase in total trade openness reduces unemployment by about one percentage point. Moreover, we show that openness affects unemployment mainly through its effect on TFP and that labor market institutions do not appear to condition the effect of openness.
