Theoretical considerations suggest that secrecy reduces spillovers almost completely through non-disclosure, while the disclosure requirement of patents generates some spillover and at the same time allows firms to appropriate knowledge. In this paper we empirically analyze whether protection by...

This paper investigates how patent applications and grants held by new ventures improve their ability to attract venture capital (VC) financing. We argue that investors are faced with considerable uncertainty and therefore rely on patents as signals when trying to assess the prospects of...

This paper analyzes the determinants of R&D co-operation among German manufacturing firms. Using firm level data from the Third Community Innovation Survey from Germany, we focus on the role of spillovers in explaining R&D cooperation. We also investigate firms' decisions to cooperate with...

In this paper we investigate the factors that lead firms to cooperate with partners from foreign countries on innovation activities. Portuguese and German data from the harmonised Community Innovation Survey (CIS III) allow us to compare innovation cooperation behaviour of private firms in the...
