Adapting Axelrod's cultural dissemination model for simulating peer effects.

We present a generic method for considering incomplete but gradually expandable sociological data in agent-based modeling based on the classic model of cultural dissemination by Axelrod. Our method extension was inspired by research on the diffusion of citizen photovoltaic initiatives, i.e. by initiatives in which citizens collectively invest in photovoltaic plants and share the profits. Owing to the absence of empirical interaction parameters, the Axelrod model was used as basis for considering peer effects with contrived interaction data that can be updated from empirical surveys later on. The Axelrod model was extended to cover the following additional features: •Consideration of empirical social science data for concrete social interaction.•Development of a variable and fine-tunable interaction function for agents.•Deployment of a generic procedure for modeling peer effects in agent-based models.
