Captures interplay between fixed ethnic markers and culturally evolved tags in the evolution of cooperation and ethnocentrism. Agents evolve cultural tags, behavioural game strategies and in-group definitions. Ethnic markers are fixed.

This is an agent-based model designed to explore the evolution of cooperation under changes in resources availability for a given population

Evolution of cooperation with strangers

The model is used to study the conditions under which agents will cooperate in one-shot two-player Prisoner’s Dilemma games if they are able to withdraw from playing the game and can learn to recogniz

Agent-Based Model for the Evolution of Ethnocentrism

Max Hartshorn | Published Sat Mar 24 21:34:18 2012 | Last modified Sat Apr 27 20:18:21 2013

This is an implementation of an agent based model for the evolution of ethnocentrism. While based off a model published by Hammond and Axelrod (2006), the code has been modified to allow for a more fine-grained analysis of evolutionary dynamics.

This model can be used to explore under which conditions agents behave as observed in field experiments on irrigation games.

A spatial prisoner’s dilemma model with mobile agents, de-coupled birth-death events, and harsh environments.

Cultural group selection model of agents playing public good games and who are able to punish and punish back.

Walk Away in groups

This NetLogo model implements the Walk Away strategy in a spatial public goods game, where individuals have the ability to leave groups with insufficient levels of cooperation.
