We study competitive interaction between profit-maximizing firms that sell software and complementary goods or services. In addition to tactical price competition, we allow firms to compete through business model reconfigurations. We consider three business models: the proprietary model (where...

Open standards and open source have become essential for ICT markets from an innovation, business, technical, and policy approach. Openness is one of the core values in standardisation settings. When it comes to the definition of ‘open', some views have pointed to a ‘clear-cut' division...

We develop a multistage game in which firms do cumulative R&D to complete a lengthy process, and we study whether firms patent intermediate results or release them in Open Source. A patent holder obtains a larger reward in the market, but since in equilibrium it forecloses R&D it remains alone...

We investigate teamwork among maintainers of open source software projects by analyzing the logs of a set of 10 large projects. Our first results suggest that collaboration among maintainers in large open-source projects seems to be generally influenced by the complexity of files as measured by...

Despite their novelty and importance, open source methods have been largely been limited to software. However, scholars have long suggested that it would be logical to organize at least one other field - drug discovery - using open source principles. This paper reviews today's relatively...

This paper seeks to close an empirical gap regarding the motivations, personal attributes and behavioral patterns among free/libre and open source (FLOSS) developers, especially those involved in community-based production, and considers the bearing of its findings on the existing literature and...

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...

We analyze the characteristics of new businesses in the German ICT industry, distinguishing them based on their choice between two IPR regimes: open source software (OSS) or closed source software (CSS). The share of new firms with an OSS-based business model has increased considerably over the...

Practitioners generally assert that collaboration with the Open Source software (OSS) community enables young software firms to achieve superior innovation performance. Nonetheless, to the best of our knowledge, scholars have never extensively speculated about this assertion or rigorously tested...

We discuss welfare and various policy interventions for mixed ICT markets where firms use either 'open source' (OS) or 'closed source' (CS) business models. We find that the existence of OS business models improves social welfare compared to all-CS industries by letting firms share costs and...
