This paper considers a dynamic model of the evolution of open source software projects, focusing on the evolution of quality, contributing programmers, and users who contribute customer support to other users. Programmers who have used open source software are motivated by reciprocal altruism to...

In the ICT sector, product-software is an important factor for the quality of the products (e.g. cell phones). In this context, open source software enables firms to avoid quality competition as they can cooperate on quality without an explicit contract. The economics of open source (OS) versus...

There is considerable debate regarding the use of intellectual property rights (IPR) to spur innovation in the software industry. In this paper we focus on the choice of intellectual property right regimes and industry growth. We begin by developing a growth optimal mixture of open source and...

Much of today’s software relies on programming code shared openly online. Yet, it is unclear why volunteer developers contribute to open-source software (OSS), a public good. We study OSS contributions of some 22,900 developers worldwide on the largest online code repository platform, GitHub,...

An extensive empirical literature indicates that, even without formal intellectual property rights, innovators enjoy a variety of first-mover advantages and that `imitation' is itself a costly activity. There is also accumulating evidence that an `open' approach to knowledge production can...

This paper examines the questions of who participates in the provision of a public good through the voluntary participation of agents in the presence of strong complementarity between a public good and a private good. We show that the greater the initial endowment of the private good that agents...

A common feature of the literature on the evolution of preferences is that evolution favors nonmaterialistic preferences only if preference types are observable at least to some degree. We argue that this result is due to the assumption that in each state of the evolutionary dynamics some...

So-called open source software (OSS) is marked by free access to the software and its source code. Copyright-based OSS licenses permit users to use, change, improve and redistribute the software, which is designed and developed in a public, collaborative manner. High quality OSS products like...

Open source software (OSS) is marked by free access to the software and its source code. OSS is developed by a "community" consisting of thousands of contributors from all over the world. Some research was undertaken in order to analyze how global the OSS community actually is, i.e. analyze the...
