This paper investigates the R&D persistence of R&D active firms in different markets with different intensities of competition, based on firm-level panel data for the period 1996-2008. In a dynamic setting of the empirical model it turns out that persistence is strongly related to market...

This paper investigates empirically the impact of diversity on the innovation performance of a firm. We created a measure for diversity that mirrors differences in the resource base of firms within an industry and tested its impact on innovation in addition to more traditional factors like...

This paper investigates empirically different ways to organize R&D within Swiss firms. Based on a longitudinal data set comprising three cross-sections (1999, 2002, and 2005) of the Swiss innovation survey, four different types of R&D strategies were identified: firms combine in-house R&D with...

Research about users as a source of innovation has been largely restricted to case studies exploring specific innovation projects at the firm level. This study assesses empirically the relationship between external end users’ knowledge as an input factor to innovation and firms’ innovation...

This paper investigates empirically different ways to organise R&D within Swiss firms. Based on a longitudinal data set comprising three cross sections (1999, 2002, and 2005) of the Swiss innovation survey, four different types of R&D strategies could have been separated; firms combine in-house...

Based on a comprehensive data set comprising 13 countries, 22 industries and a period of 30 years we investigate the impact of internal and external knowledge pools of both green and ‘other than green’ technologies on green patent activities. It turned out that the internal green knowledge...

This paper analyses the relationship between past innovation output, competition, and future innovation input in a dynamic econometric setting. We distinguish two dimensions of competition that correspond to the concepts of product substitutability and entry barriers due to fixed costs. Based on...
