We simulate a spatial behavioral model of the
diffusion of an infection to understand the role of
geographical characteristics: city size, density,
distribution of initial outbreaks, movement of agents.
We show that several invariance properties of the SIR model with respect to these variables do not hold
when agents are placed in a two dimensional space. Local herd immunity plays a fundamental role in changing the dynamics of the
infection. We also show that geographical factors affect how
behavioral responses affect the epidemics. We derive relevant implications for the estimation of epidemiological models with panel data from several geographical units.
