The rapid diffusion of open source software (OSS), the significant investments observed in OSS projects, and the new inter-firm collaborative possibilities enabled by such OSS projects have generated a substantial literature on the economics of OSS development. However, this literature mainly...

The paper provides empirical evidence for the question whether firms' ITenabled labour productivity is affected by the age structure of the workforce. We apply a production function approach with heterogenous labour to firmlevel data from German manufacturing and services industries. We find...
