We study an endogenous growth model where a profit-motivated R and D sector coexists with the introduction of free blueprints invented by philanthropists. These goods are priced at marginal cost, contrary to proprietary ones which are produced by a monopoly owned by the inventor. We show that...

During the '60s and the '70s, basically all software was Open Source and everyone was allowed to copy, modify and redistribute computer programs. When software ceased to be hardware-specific and the diffusion of computers took off, firms started to produce software independently from hardware...

The rivalry between developers of open source and proprietary software encourages open source developers to court users and respond to their needs. If the open source developer wants to promote her own open source standard and solutions, she may choose liberal license terms such as those of the...

This paper analyzes a dynamic mixed duopoly in which a profit-maximizing competitor interacts with a competitor that prices at zero (or marginal cost), with the cumulation of output affecting their relative positions over time. The modeling effort is motivated by interactions between Linux, an...

There is considerable debate regarding the use of intellectual property rights (IPR) to spur innovation in the software industry. In this paper we focus on the choice of intellectual property right regimes and industry growth. We begin by developing a growth optimal mixture of open source and...

Recently the software industry has experienced fundamental changes in market structure through the entry of open source competitors, e.g. Linux's entry into the operating systems market. In a simple model we examine the effects of such a change in market structure from monopoly to duopoly under...

In enterprise software markets, firms are increasingly using services-based business models built on open-source software (OSS) to compete with established, proprietary software firms. Because thirdparty firms can also strategically contribute to OSS and compete in the services market, the...

To distribute software, commercial vendors of proprietary software have the opportunity to use some dual licensing (DL) strategy i.e. to provide their software under two different licensing terms (proprietary and open source). We investigate the relevance and impacts of this distribution...

When are too many Open Source Licenses enough? There is a need to reduce the number of Open Source Licenses that are available, in the Open Source Software license weltanschauung. However there are arguments for the need to add to the suite of licenses because of the failure of the available...
