Behavior and the Dynamics of Epidemics

I use a model of private and public behavior to mitigate disease transmission during the COVID pandemic over the past year in the United States to address two questions: What dynamics of infections and deaths should we expect to see from a pandemic? What are our options for mitigating the impact of a pandemic on public health? I find that behavior turns what would be a short and extremely sharp epidemic into a long, drawn out one. Absent the development of a technological solution such as vaccines or life-saving therapeutics, additional public health interventions suffer from rapidly diminishing returns in improving long-run outcomes. In contrast, rapidly implemented non-pharmaceutical interventions, in combination with the rapid development of technological solutions, could have saved nearly 300,000 lives relative to what is now projected to occur.
