Other-regarding preferences and altruistic punishment: A Darwinian perspective

This article examines the effect of different other-regarding preference types on the emergence of altruistic punishment behavior from an evolutionary perspective. Our findings corroborate, complement, and interlink the experimental and theoretical literature that has shown the importance of other-regarding behavior in various decision settings. We find that a selfish variant of inequity aversion is sufficient to quantitatively explain the level of punishment observed in contemporary experiments: If disadvantageous inequity aversion is the predominant preference type, altruistic punishment emerges in our model to a level that precisely matches the empirical observations. We use a new approach that closely combines empirical results from a public goods experiment together with an evolutionary simulation model. Hereby we apply ideas from behavioral economics, complex system science, and evolutionary biology.
