Towards mechanistic explanations of cooperative sustainable resource use

ABM meets behavioural experiments of cooperation in common-pool resources

Behavioural economic experiments are providing new insights into the real behaviour of humans in common pool resource use, such as the use of a fish stock or water for irrigation. They have highlighted for instance the importance of communication for sustainable resource use. However, how communication is initiated and what aspects of communication are relevant is still poorly understood. In this project we develop an agent-based model based on a series of experiments that investigated the behaviour of users of a resource that can exhibit threshold dynamics, i.e. once a certain threshold of resource size is crossed its regeneration rate drastically declines. The experiments show that some groups manage to use the resource sustainably while others don’t and that the share of successful groups increases when the resource exhibits a threshold. The aim of the model is to identify possible factors and aspects of human decision making and behaviour that can explain the observed outcomes of the experiments. We develop the model using experimental data, observations and theories of human behaviour. In doing so we test hypotheses about drivers of cooperation in common pool resource use. We are particularly interested in the role of confidence about the knowledge of oneself or the group for communication and the development of sharing rules.
Keywords: human (group) behaviour, common pool resource dilemma, collective behaviour.
