This paper addresses the question of the software companies’ timing of adoption of the open source software (OSS) business models comprising the supply of OSS products and/or services. The game-theoretic technology adoption models do not explain well the observed diffusion patterns of the OSS business model among the sample of 716 European software firms.  read more »
