Is altruism evolutionarily stable
We develop an evolutionary approach to explain altruistic preferences. Given their preferences, individuals interact rationally with each other. By comparing the success of players with different preferences, we investigate whether evolution favors altruistic or selfish attitudes. The outcome depends on whether the individuals' interactions are strategic complements or substitutes. Altruism and...
متن کاملAltruism and envy in contests: An evolutionarily stable symbiosis
Altruists and envious people who meet in contests are symbionts. They do better than a population of narrowly rational individuals. If there are only altruists and envious individuals, a particular mixture of altruists and envious individuals is evolutionarily stable.
متن کاملIs altruism evolutionarily stable? And envy and malevolence? Remarks on Bester and Güth
In a convincing analysis of the conditions and strength of altruism, Bester and Güth [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 malevolence (or envy) as well. ©2000 Elsevier Science B.V. All rights reserved. JEL classification: A13; C7...
متن کاملEvolutionarily stable dispersal strategies.
Using the idea that life-history parameters are subject to natural selection and should approach values that are stable optima, with the population immune to invasion by mutant individuals, we derive an analytic expression for the evolutionarily stable dispersal rate in a stochastic island model with random site extinction. The results provide interesting contrasts between three different optim...
متن کامل10 Evolutionarily Stable Strategies
In 1973 the biologist John Maynard Smith and the mathematician G. R. Price wrote an article in Nature showing how game theory applies to the behavior of animals (Maynard Smith and Price 1973). Maynard Smith went on to write a book on the subject (Maynard Smith 1982), which has become a classic. The idea of applying game theory to animals, and not just the higher primates, but fish, dung beetles...
