A macroeconomic model of an epidemic with silent transmission and endogenous self-isolation
1Bank of Canada.
Abstract:
I study the interaction between epidemics and economic decisions in a model where: (i) agents allocate their time to market and home production and social and home leisure, (ii) these activities differ in their degree of contagiousness, (iii) some infected individuals are indistinguishable from susceptible individuals and (iv) agents are not necessarily rational. For baseline parameter values for the COVID-19 pandemic, I find that agents partially self-isolate by allocating more time to home activities and that the effective reproduction number of the disease stabilizes at 1. Detection and isolation of infected individuals severely mitigate the recession and deaths caused by the pandemic.

Infection
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...
