Estimating Monetary Policy Rules when the Zero Lower Bound on Nominal Interest Rates is Approached

Abstract
Monetary policy rule parameters estimated with conventional estimation techniques can be severely biased if the estimation sample includes periods of low interest rates. Nominal interest rates cannot be negative, so that censored regression methods like Tobit estimation have to be used to achieve unbiased estimates. We use IV-Tobit regression to estimate monetary policy responses for Japan, the US and the Euro area. The estimation results show that the bias of conventional estimation methods is sizeable for the inflation response parameter, while it is very small for the output gap response and the interest rate smoothing parameter. We demonstrate how IV-Tobit estimation can be used to study how policy responses change when the zero lower bound is approached. Further, we show how one can use the IV-Tobit approach to distinguish between desired policy responses, that the central bank would implement if there was no zero lower bound, and the actual ones and provide estimates of both.

Konjunktur aktuell: Deutsche Wirtschaft erholt sich seit dem Frühjahr
Konjunktur aktuell,
No. 3,
2013
Abstract
Realwirtschaftliche Indikatoren deuten daraufhin, dass die Schwächephase der deutschen Konjunktur im Frühsommer ausläuft. So werden im Baugewerbe die witterungsbedingten Produktionsausfälle aufgeholt, und Aktivitäten zur Beseitigung der Hochwasserschäden kommen hinzu. Auch der private Konsum wirkt stützend. Das Bruttoinlandsprodukt wird im laufenden Jahr wohl um 0,7% und im kommenden Jahr um 2% steigen. Die Arbeitslosenquote wird im Jahr 2013 6,5% und im Jahr 2014 6,1% betragen. Der Finanzierungssaldo der öffentlichen Haushalte wird sich im Jahr 2013 bei einer leicht expansiv ausgerichteten Finanzpolitik geringfügig verschlechtern und im kommenden Jahr aufgrund wieder etwas stärker expandierender Einnahmen einen Überschuss in Höhe von 0,4% in Relation zum Bruttoinlandsprodukt aufweisen. Die Schulden- und Vertrauenskrise im Euroraum stellt nach wie vor das Hauptrisiko für die deutsche Konjunktur dar.

In which Ways do Universities React to New Technologies? The Case of Photovoltaics

Abstract
Universities can be conceived as actors in regional innovative systems with the functions to make available new knowledge for a region, to contribute to the human capital formation by teaching, and to the extension of the knowledge by research. These functions are in particular important concerning the adaptation of new technologies, e.g. photovoltaics. 89 German universities – amongst them 65 universities of applied sciences – meanwhile offer 171 full-time study courses with a degree oriented to photovoltaics. Each federal state has at least one university location offering such degrees. A certain spatial concentration of courses can be shown for Saxony, for the Ruhr Area and for the Rhine Main Region. Almost 90% of the degrees are offered by faculties of engineering. 43% of the universities with degrees in photovoltaics have successfully applied for research grants from the photovoltaics research programs of the federal government. These numbers show a spatial concentration of research in the South whereas the photovoltaics industry is concentrated in the East of Germany. This distribution indicates that the research opportunities tied to the photovoltaics industry are not in the Eastern part of Germany. Further research will have to pay more attention to the role of research institutes.
