This study explores a new modelling approach that bridges the gap between multilateral country-level data and the bilateral-model based, goods-market specific purchasing power parity (PPP) hypothesis. Under this approach, PPP is embedded in latent common factors, extractable from a large set of...

We study the Beaudry and Portier (2006)-hypothesis of delayed-technology diffusion and news-driven business cycles. For German data on TFP and stock prices we find qualitatively similar empirical evidence. Quantitatively, however, an impulse response analysis suggests that a substantial part of...

To provide an modelling strategy with transparent and theoretically coherent foundation has been one of the targets of the paper by Garratt, Lee, Pesaran and Shin. They develop a core model for a small open economy based production technology, arbitrage conditions, flow identities and long-run...

Recent theoretical advances in consumption theory suggest that there may exist predictable consumption surges which, if not taken sufficiently into account in forecasting, may lead to predictable forecast errors. We use this insight to identify economic variables that might help improve the...

Der vorliegende Beitrag geht an Hand verschiedener Indikatoren der Frage nach, ob sich von der finanziellen Seite her die wirtschaftlichen Risiken bei westdeutschen Unternehmen vergrößert haben. Die Untersuchung stützt sich auf eine Sonderauswertung der Bilanzstatistik der Deutschen...

Declining R&D intensities at the national level coincide with growing international technological links. Deviations of individual OECD countries from the average R&D intensity reflect differences in industry structure as well as in sectoral R&D intensity. At the same time, the sectoral...

In this study of Ghana integrated to the world economy, we focus primarily on Ghana-UK-Germany trade axis partly because of Ghana's relative dependence on the EU for her international trade. The study employs „representative“ country macroeconometric models of these economies, using data...

Mit dem vorliegenden Aufsatz wird das Ziel verfolgt, die Erklärung der gesamtwirtschaftlichen Unternehmensinvestitionen (Ausrüstungsinvestitionen der Unternehmen und Wirtschaftsbauinvestitionen) durch die Einbeziehung von Variablen, mit denen sich Unsicherheit abbilden läßt, zu ergänzen. In...
