Classes I have taught:

Teaching Social Simulation

I have developed seven replications of prominent papers that use social simulation to advance and/or test the internal consistency of prominent sociological theories. The development of these teaching materials was done in collabotation with James Kitts in the context of a Carla B. Howery Teaching Enhancement Grant. I have presented these teaching materials at ASA (see poster here). These materials have also been used in summer methods courses at UMass, where I have been a guest lecturer.

The agent-based models I developed are:

  • An agent-based diffusion model on the emergence of intergroup inequality via homophily and network externalities published in AJS by Paul DiMaggio and Filiz Garip.
  • An agent-based model on the emergence of antisocial norms via rival incentives and peer pressure published in ASR by James Kitts.
  • An agent-based model on the emergence of collective action via adaptive thresholds and stochastic learning published in ASR by Michael Macy.
  • An agent-based model on the emergence of generalized exchange through an evolutionary approach published in AJS by Nobuyuki Takahashi.
  • An agent-based model on the emergence of opinion similarity via homophily and influence published in AJS by Daniel Dellaposta and colleagues.

The system-level models I developed are:

  • A model on state legitimacy and imperialist capitalism published in Sociological Methodology by Robert Hanneman and colleagues.
  • A model on the emergence of cooperation with three different strategies that evolve over time published in the Journal of Conflict Resolution by Jack Hirshleifer and Juan Carlos Martínez.
