This paper asks whether population growth is conducive to the sustainability of cooperation. A simple model is developed in which farmers who live around a circular lake engage in trade with their adjacent neighbors. The payoffs from this activity are governed by a prisoner's dilemma rule of...

This paper reports the results of a meta-study of 89 prisoner's dilemma experiments comprising more than 3000 participants across 6 countries. We organize existing evidence and explain seemingly contradictory results in the existing literature by focusing on two dimensions of the dilemma:...

Do large language models (LLMs) - such as ChatGPT 3.5, ChatGPT 4.0, and Google's Gemini 1.0 Pro - simulate human behavior in the context of the Prisoner's Dilemma (PD) game with varying stake sizes? This paper investigates this question, examining how LLMs navigate scenarios where...

This paper asks whether population growth is conducive to the sustainability of cooperation. A simple model is developed in which farmers who live around a circular lake engage in trade with their adjacent neighbors. The payoffs from this activity are governed by a prisoner's dilemma "rule of...

We fuse a social dilemma game and a game pitting the group against nature, where the group's probability of avoiding disaster depends on the resources it raises from members. The result is the Nederlander-Prisoner's Dilemma Game where the cost of failure is equally shared. We introduce the...

Explaining the evolution and maintenance of cooperation among unrelated individuals is one of the fundamental problems in biology and the social sciences. Recent experimental evidence suggests that altruistic punishment is an important mechanism to maintain cooperation among humans. In this...

The conflict between pro-self and pro-social behaviour is at the core of many key problems of our time, as, for example, the reduction of air pollution and the redistribution of scarce resources. For the well-being of our societies, it is thus crucial to find mechanisms to promote pro-social...

The emergence and survival of cooperation is one of the hardest problems still open in science. Several factors such as the existence of punishment, repeated interactions, topological effects and the formation of prestige may all contribute to explain the counter-intuitive prevalence of...
