This paper studies the evolution of both characteristics of reciprocity - the willingness to reward friendly behavior and the willingness to punish hostile behavior. Firstly, preferences for rewarding as well as preferences for punishing can survive evolution provided individuals interact within...

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...

Darwin’s (1871) observation that evolution has produced in us certain emotions responding to right and wrong conduct that lack any obvious basis in individual utility is a useful springboard from which to clarify the role of emotion in moral judgment. The problem is whether a certain class of...

This paper represents the third part of a research work dealing with the integration of economic efficiency and equity considered as a no-envy concept. Specifically, I examine here the problem of reduction of the malicious envy in a cultural evolutionary context. In fact, both in the case of...

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...

This paper develops an evolutionary approach to investigate whether revealing one's own emotions such as sel shness, altruism or envy has evolved in humans through a process of natural selection. This paper nds two results. First, if the revealing trait (revealing or hiding) and the...

We introduce a generalized theoretical approach to study imitation models and subject themodels to rigorous experimental testing. In our theoretical analysis we find that the differentpredictions of previous imitation models are due to different informational assumptions, notto different...

Despite the accumulation of research on indirect reciprocity over the past 30 years and the publication of over 100,000 related papers, there are still many issues to be addressed. Here, we look back on the research that has been done on indirect reciprocity and identify the issues that have...

Problems of the commons exist in a wide variety of settings ranging in size and complexity from the family (e.g., the household budget and the kitchen sink) to the global scale (e.g., loss of biodiversity and global warming). Game theory is a useful theoretical tool for representing a...
