This paper presents first results from research into open source projects from a software engineering perspective. The research methodology employed relies on public data retrieved from the CVS-repository of the GNOME project and relevant discussion groups.(...)

In spite of Microsoft´s quasi monopoly position in the market for operating systems Linux has succeeded to become a serious competitor of Microsoft Windows. From an economic standpoint this fact raises some puzzles.(...)

Open source is a term for software published under licence that does not give any property rights to the developers. Recently, attempts have been made to explain open source as the result of the collaboration of purely self-interested, utility-maximizingindividuals.(...)

Open source software is a collective term for different software licenses that give users access to the source code of the programs and thus allow them to develop the programs according to their needs. Because nobody can be excluded and because there is no rivalry in consumption, the open source...

Die vorliegende Arbeit beschäftigt sich mit der Frage, wie kommerzielle Unternehmen die Innovationskraft von Open Source Projekten nutzen können.Als Beispiele werden Red Hat und Netscape behandelt.

Open source software production is a successful new production model in which a public good is voluntarily provided. We argue that by studying this new production model we gain valuable insightfor organization theory beyond software production.(...)

Open source software production is a succesful new innovation model in which a public good is voluntarily provided. We argue that by studying this new innovation model we gain valuable insigth for innovation theory beyond software production.

Open source software production is a highly successful innovation model. But it is, by far, not a singular case but rather one example of "virtual communities of innovation". The purpose of this paper is to inquire under which conditions the new innovation model might work in general...

Open source projects produce goods or standards that do not allow for the appropriation of private returns by those who contribute to these projects. In this paper we analyze why programmers will nevertheless invest their time and effort to code open source software. We argue that the particular...

In Open-Source-Software-Projekten entwickeln zunächst voneinander unabhängige Software-Entwickler lediglich verbunden über das Internet Software - und zwar zum Teil ganz ohne monetäres Entgelt.
