During the last five years higher education research in Germany seems to be in a significant upturn. This is a side effect partly of the obvious boom of empirical educational research in general and partly of the reform movement that has affected the German higher education system since middle...

Die amtlichen Hochschulstatistiken sind als berichtszeitraumbezogene Erhebungen ausgestaltet. Daher konnten Entwicklungen auf individueller Ebene im Zeitverlauf bislang nicht oder nur unzureichend dargestellt werden. Mit der Einführung einer Studienverlaufsstatistik durch das novellierte...

Der Beitrag gibt Auskunft über den Stand der Erfassung von Migration in den amtlichen Schulstatistiken der Bundesländer. Hierauf aufbauend werden die Anteile von Schülerinnen und Schülern mit nichtdeutscher Staatsangehörigkeit sowie von Schülerinnen und Schülern mit Migrationshintergrund...

How strong are strategic complementarities in price setting across firms? In this paper, we provide a direct empirical estimate of firms' price responses to changes in prices of their competitors. We develop a general framework and an empirical identification strategy to estimate the...

This paper reports the results of an ad hoc survey on price-setting behaviour conducted in February 2004 among 2,000 Belgian firms. The reported results clearly deviate from a situation of perfect competition and show that firms have some market power. Pricing-to-market is applied by a majority...

Using Logistic Normal regressions, we model the price-setting behaviour for a large sample of Belgian consumer prices over the January 1989 - January 2001 period. Our results indicate that time-dependent features are very important, particularly an infinite mixture of Calvo pricing rules and...
