Competitive Strategy of Proprietary Software Firms in an Open Source Environment

This paper analyzes the competitive strategy of proprietary software (PS) firm in the presence of open-source software (OSS) where the copyright holder has granted software users access and use of OSS without any obligation regarding source code disclosure and royalty payments. The OSS is developed by volunteer programmers, while the firm incurs costs to hire programmers to build the PS. The firm has a quality advantage because, first, it can provide professional technical support and promotion, and second, it is difficult for the OS community to collaborate for the production and maintenance of the OSS. The analysis is based on two scenarios: (1) the OSS is available free of charge; (2) the OSS is distributed by fringe vendors who can provide OSS quality upgrades. We find that both types of software can coexist in equilibrium. Furthermore, despite the fact that PS enjoys a quality advantage, it will optimally set a lower quality than OSS. The comparative statics show that a change in each market parameter can lead the firm to simultaneously increase (or decrease) both the PS price and quality. We consequently evaluate the impact on the firm's profit and consumer surplus
