Virtual Seminar in Economic Theory: Equilibrium Social Distancing

Thursday, 4 June 2020
16:00 to 17:30
Flavio Toxvaerd, University of Cambridge
Virtual seminar

Speaker: Flavio Toxvaerd, University of Cambridge

Abstract:

This paper presents an economic model of an epidemic in which susceptible individuals may engage in costly social distancing in order to avoid becoming infected. Infected individuals eventually recover and acquire immunity, thereby ceasing to be a source of infection to others. Under non-cooperative and forward-looking decision making, equilibrium social distancing arises endogenously around the peak of the epidemic, when disease prevalence reaches a critical threshold determined by preferences. Spontaneous, uncoordinated social distancing thus acts to áatten the curve of the epidemic by reducing peak prevalence. In equilibrium, social distancing stops once herd immunity sets in but acts to extend the duration of the epidemic beyond the benchmark of a non-behavioural epidemiological model. Comparative statics with respect to the model parameters indicate that the curve becomes áatter (i) the more infectious the disease is and (ii) the more severe the health consequences of the disease are for the individuals.
