This paper investigates whether firms innovate persistently or discontinuously over time using an innovation panel data set on German manufacturing and service firms for the period 1994?2002. We find that innovation behaviour is permanent at the firm?level to a very large extent. Using a dynamic...

This paper studies the impact of process and product innovations introduced by firms on employment growth in these firms. A simple model that relates employment growth to process innovations and to the growth of sales separately due to innovative and unchanged products is developed and estimated...

This paper explores the role of R&D worker mobility on innovation performance. As one main novelty, we employ churning as a measure for worker mobility. Churning depicts the number of workers which are replaced by new ones. It is a very informative indicator since a firm may be exposed to...

This study presents a novel empirical approach to identify financing constraints for innovation based on the concept of an ideal test (Hall 2008). Firms were offered a hypothetical payment and were asked to choose between alternatives of use. If they selected additional innovation projects, they...

Although the costs associated with moving an antiquated socialist economy toward its capitalist counterpart was anticipated to be significant, German industrial efficiency was expected to quickly overcome any challenges. Things turned out rather differently. Conventional wisdom blamed poor...

Die Studie stellt die verbreitete These, die seit 2001 trotz konjunktureller Schwäche anhaltend hohe Inflationsrate im Euroraum sei die Folge struktureller Rigiditäten, in Frage. Anhänger dieser These sehen in Strukturreformen, die diese Rigiditäten beseitigen, die wichtigste Voraussetzung...

This study presents a novel empirical approach to identify financing constraints for innovation based on the idea of an ideal test as suggested by Hall (2008). Firms were offered a hypothetical payment and were asked to choose between alternatives of use. If they choose additional innovation...
