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...

Concern about potential free riding in the provision of public goods has a long history. More recently, experimental economists have turned their attention to the conditions under which free riding would be expected to occur. A model of free riding is provided here which demonstrates that...

Some philosophers and social scientists have stressed the importance for good government of an altruistic citizenry that values the well being of one another. Others have emphasized the need for incentives that induce even the self interested to contribute to the public good. Implicitly most...

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...

We investigate the quality provision behavior and its implications for the occurrence of collusion in competitive health care markets where providers are assumed to be altruistic towards patients. For this, we employ a laboratory experiment with a health care market framing where subjects decide...

We study an endogenous growth model where a profit-motivated R and D sector coexists with the introduction of free blueprints invented by philanthropists. These goods are priced at marginal cost, contrary to proprietary ones which are produced by a monopoly owned by the inventor. We show that...

This chapter critically analyses contributions to evolutionary game theory by such writers as Robert Trivers, John Maynard-Smith, and Robert Axelrod. It develops four key arguments. First, that the behavioral propensities that manifest themselves in altruistic behavior are empirically relevant,...

This paper presents an evolutionary model in which altruists and egoists simultaneously survive natural selection. Successive generations of randomly paired agents play a two-stage game consisting first of a choice of technology and second a choice of effort level. This setting induces a form of...

In a convincing analysis of the conditions and strength of altruism, Bester and Guth [Journal of Economic Behavior & Organization, Vol. 34, 1998, 193-209] unfortunately restrict the interpretation of their results. Their paper provides us with an analysis of the conditions and strength of...
