Please feel free to request the source code of any of the models below. These computational models include my own published work and replications of prominent sociological papers. Importantly, they are also interactive teaching tools
to explore sociological theories, social processes, and emergent phenomena.

I developed the code for the inter-organizational application of the agent-based model in my 2016 PLoS ONE paper. [data and code][see article]

My replication of Kitts (2006). This is an agent-based model on the emergence of antisocial norms via rival incentives and the effectiveness of peer influence.

My replication of Hanneman, Collins and Mordt (1995). This is a system-level model on state legitimacy and imperialist capitalism.
