SIMULATION RESEARCH

This page contains material associated with my simulation research. Two projects are currently underway. The first, co-authored with Maurits van der Veen, examines the diffusion of ideas within a society. In particular, we are interested in the diffusion of shared identity. The second, co-authored with Max Cantor, examines the evolution of trading and war making strategies. As the models and papers are completed, they will be added to the web site.

Idea Diffusion Project (with Maurits van der Veen)
• Paper in Microsoft Word Format.
• Technical Appendix for Model.
• Codebook for Shared Identity Model
• Shared Identity Model (Hold the "shift key" down and click on the link to save it to your hard drive. After unzipping the model click on "sharedIDgui.jar" in the repast-1.4.1/maurits/sharedID/ subdirectory to start the model.)

Trade and War Project (with Max Cantor)
• Paper: "The Evolution of Cooperation: in a Hierarchically Structured, Two-Issue Iterated Prisoner’s Dilemma Game:An Agent-Based Simulation of Trade and War."
  • Paper in Microsoft Word format
  • Figures in Microsoft PowerPoint format
• Codebook for Trade and War Model
• Trade and War Model (Hold the "shift key" down and click on the link to save it to your hard drive. After unzipping the model click on "rousseaumodel.jar" in the repast-1.4.1/cantor/jar/ subdirectory to start the model.)

Social Mobilization (with Max Cantor)
• Paper: "From Globalization to Terrorism: A Computer Model of Social Mobilization."

Democracy and War (with Maurits van der Veen)
• Paper: "The Evolution of the Democratic Peace: An Agent-Based Computer Simulation."
