A large number of studies has been canvassed by the growing rates of diffusion of Open Source Software. However, a formal analysis of the process of competition between open–source and proprietary software is still missing. We propose an epidemic model of innovation diffusion to deal with the different factors (profits for proprietary software and developers’ motivations for open–source software) upon which such a process of competition ultimately depends. Moreover, we add network effects and switching costs, together with the endogenisation of the parameters of the speed of diffusion influencing the final outcome. We show the conditions for an asymptotically stable equilibrium to exist, where both softwares coexist. When the propagation coefficient is en- dogenous, winner–take–all solutions are also likely.

Abstract
A large number of studies has been canvassed by the growing rates of diffusion of Open Source Software. However, a formal analysis of the process of competition between open–source and proprietary software is still missing. We propose an epidemic model of innovation diffusion to deal with the different factors (profits for proprietary software and developers’ motivations for open–source software) upon which such a process of competition ultimately depends. Moreover, we add network effects and switching costs, together with the endogenisation of the parameters of the speed of diffusion influencing the final outcome. We show the conditions for an asymptotically stable equilibrium to exist, where both softwares coexist. When the propagation coefficient is en- dogenous, winner–take–all solutions are also likely.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
