Chapter 11 Natural Kantian or ZOO ECONOMICUS ? Evolutionary theories of selfishness and altruism among men and beasts
Bergstrom, Theodore C. - In: Handbook of the economics of giving, altruism and …, (pp. 771-817). 2006
This paper addresses the question of whether our evolutionary history suggests that humans are likely to be individually selected selfish maximizers or group selected altruists. It surveys models from the literature of evolutionary biology in which groups are formed and dissolved and where the...

Coevolution of cooperation, preferences, and cooperative signals in social dilemmas
Müller, Stephan; Wangenheim, Georg von - 2016
We study the coevolution of cooperation, preferences and cooperative signals in an environment where individuals engage in a signaling-extended prisoner's dilemma. We identify a new type of evolutionary equilibrium - a transitional equilibrium - which is constituted and stabilized by the dynamic...

Cooperate without looking in a non-repeated game
Hilbe, Christian; Hoffman, Moshe; Nowak, Martin A. - In: Games 6 (2015) 4, pp. 458-472
We propose a simple model for why we have more trust in people who cooperate without calculating the associated costs. Intuitively, by not looking at the payoffs, people indicate that they will not be swayed by high temptations to defect, which makes them more attractive as interaction partners....

Coevolution of cooperation, preferences, and cooperative signals in social dilemmas
Müller, Stephan; Wangenheim, Georg von - 2019 - Revised version June 2019
We study the coevolution of cooperation, preferences, and cooperative signals in an environment where individuals engage in a signaling-extended prisoner's dilemma. We prove the existence of a cooperative equilibrium constituted by a (set of) limit cycle(s) and stabilized by the dynamic...

Evolution of cooperation in social dilemmas : signaling internalized norms
Müller, Stephan; Wangenheim, Georg von - 2014
The article suggests a new explanation for cooperation in large, unstructured societies that avoids the restrictions required in most previous attempts. Our explanation deals with the role of internalized norms. Even internalized norms, i.e. norms that alter the perceived utility from acting in...

Evolution of cooperation in social dilemmas : signaling internalized norms ; conference paper
Müller, Stephan; Wangenheim, Georg von - 2014
Economists have a long tradition in identifying the evolution of cooperation in large, unstructured societies as a puzzle. We suggest a new explanation for cooperation which avoids restrictions of most previous attempts. Our explanation deals with the role of internalized norms for cooperation...

Selfish altruism, fierce cooperation and the emergence of cooperative equilibria from passing and shooting
Askitas, Nikos - 2014
There is continuing debate about what explains cooperation and self-sacrifice in nature and in particular in humans. This paper suggests a new way to think about this famous problem. I argue that, for an evolutionary biologist as well as a quantitative social scientist, the triangle of two...

When and how does mutation-generated variation promote the evolution of cooperation?
Spichtig, Mathias; Egas, Martijn - In: Games 10 (2019) 1/4, pp. 1-17
Mutation-generated variation in behavior is thought to promote the evolution of cooperation. Here, we study this by distinguishing two effects of mutation in evolutionary games of the finitely repeated Prisoner’s Dilemma in infinite asexual populations. First, we show how cooperation can...

Chapter 3 : Reciprocal Altruism, Norms, and Evolutionary Game Theory
Field, Alexander J. - 2009
This chapter critically analyses contributions to evolutionary game theory by such writers as Robert Trivers, John … the passive altruism reflected in failure to harm. Second, that an evolutionary approach emphasizing group or multilevel … models in their implications. In particular, the justification by appeal to evolutionary theory for the standard economic …
