This webinar will explore the value of enriching a COVID-19 model to incorporate more of the detailed choices people make. While more of the nuances of policy can be explored, the challenges of tractability and transparency grow. To start the conversation, Dr. Tertlilt will share results from her recent study “An Economic Model of the COVID-19 Epidemic: The Importance of Testing and Age-Specific Policies” which augments a standard SIR epidemiological model with individual choices regarding how much time to spend working and consuming outside the house, both of which increase the risk of transmission to examine the potential impact of a targeted lockdown of older age groups in combination with other interventions to control the SARS-CoV-2 pandemic. There were 85 live attendees.
