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...

I consider a Vickrey-Salop model of spatial product differentiation with quasi-linear utility functions and contrast two modes of production, the proprietary model where entrepreneurs sell software to the users, and the open source model where users participate in software development. I show...

We present a framework to evaluate the impact of digital music distribution. We set up a representative model that enables the comparative static analysis. We then interpret two empirical observations about the music industry, the sales decline and the price constancy, and fit the model to these...

The aim of this article is to report on an experiment in publishing an open access journal and learn from it about the larger field of open access publishing. The experiment is the launch of the European Journal of Comparative Economics (EJCE), an on-line refereed and open access journal,...

We study the production of knowledge when many researchers or inventors are involved, in a setting where there tensions can arise between individual public and private contributions. We first show, with the aid of a simple model, that without some kind of co-ordination, production of the public...

Die Diskussion um das digital divide oder die digitale Spaltung, wie sie für den deutschsprachigen Raum übersetzt wird, wird nun schon seit nahezu zehn Jahren intensiv geführt.1 Vor allem im Rahmen der politischen Diskussion hat sich das Bedrohungsszenario einer digitalen Spaltung innerhalb...

Strategic patenting is widely believed to raise the costs of innovating, especially in industries characterised by cumulative innovation. This paper studies the effects of strategic patenting on R&D, patenting and market value in the computer software industry. We focus on two key aspects:...

Digital technologies allow the implementation of more decentralized Property Rights (PR) systems as compared to those traditionally set-up by public authorities at the national level. The self-implementation of exclusive rights of use over information and the design of self-regulation by virtual...

Digital Technologies make it possible to decentrally settle institutional frameworks based on self-implementation of exclusive rights of use over information and on the self-regulation of on-line communities. Through a decentralized system of IPRs and collective rules setting of this kind agents...
