Die schnelle Entwicklung des Informationsmediums Internet bietet Online-Zeitungen ein hohes Wachstumspotenzial. Allerdings können die bisher meist kostenlosen Online-Zeitungen allein durch Werbeeinnahmen kaum profitabel gestaltet werden. Timo Schulze untersucht, wie optimale Nutzungspreise für...

This paper introduces methods for computing impulse response functions that do not require specification and estimation of the unknown dynamic multivariate system itself. The central idea behind these methods is to estimate flexible local projections at each period of interest rather than...
