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...

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...

In this paper I study how innovation investment in a software duopoly is affected by the fact that one of the firms is, or might become Open Source. Firms can either be proprietary source (PS) or open source (OS), and have different initial technological levels. An OS firm is a for profit...

This article describes six common challenges of design, incentives, and governance that arise in establishing platform businesses. It also proposes solutions. It considers, for example, how to open a platform to decentralized innovation yet still earn a return; how to incorporate best-of-breed...

This book contains the articles presented at the first International gretl Conference, held on may 28-29, 2009 in Bilbao, Spain.

Using a unique dataset we examine empirically which factors explain output per contributor in open source projects. We find that the output per contributor of open source programmes is much higher when licenses are less restrictive. Further examination suggests that the difference in output per...

El open source se ha convertido en una de las ideas más exitosas desde el surgimiento de Internet. En este artículo se analizan las razones de este éxito. The open source has become one of the most successful ideas from the sprouting of Internet. In this article the reasons of this success...

A review of the basic theory of optimal open-source software contributions points to three key factors affecting the decision to contribute to the open-source development process: nonpecuniary benefits, future expected monetary returns, and open-source licence type. This paper argues that...

Digital goods are bit strings, sequences of 0s and 1s, that have economic value. They are distinguished from other goods by five characteristics: digital goods are non-rival, infinitely expansible, discrete, aspatial, and recombinant. The New Economy is one where the economics of digital goods...
