Explores how social networks affect implementation of institutional rules in a common pool resource.

An Agent-Based Model of Collective Action

Hai-Hua Hu | Published Tue Aug 20 16:45:15 2013

We provide an agent-based model of collective action, informed by Granovetter (1978) and its replication model by Siegel (2009). We use the model to examine the role of ICTs in collective action under different cultural and political contexts.

Vulnerability of Cooperation Due to Limited Vision

Marco Janssen | Published Thu Dec 2 23:00:56 2010 | Last modified Sat Apr 27 20:18:53 2013

This model describes the consequences of limited vision of agents in harvesting a common resource. We show the vulnerability of cooperation due to reduced visibility of the resource and other agents.

CPNorm is a model of a community of harvesters using a common pool resource where adhering to the optimal extraction level has become a social norm. The model can be used to explore the robustness of norm-driven cooperation in the commons.

The Groundwater Commons Game

Juan Carlos Castilla-Rho Rodrigo Rojas | Published Thu May 11 13:04:53 2017 | Last modified Sat Sep 16 03:46:39 2017

The Groundwater Commons Game synthesises and extends existing work on human cooperation and collective action, to elucidate possible determinants and pathways to regulatory compliance in groundwater systems globally.

This model allows for the investigation of the effect spatial clustering of raw material sources has on the outcome of the neutral model of stone raw material procurement by Brantingham (2003).
