“Tractable Epidemiological Models for Economic Analysis,” CEPR, 2020

CEPR Discussion Paper 14791, May 2020, with Martin Gonzalez-Eiras. PDF (local copy). We contrast the canonical epidemiological SIR model due to Kermack and McKendrick (1927) with more tractable alternatives that offer similar degrees of “realism” and flexibility. We provide results connecting the different models which can be exploited for calibration purposes. We use the expected spread of COVID-19 in the United States to exemplify our results.

“On the Optimal ‘Lockdown’ during an Epidemic,” CovEc, 2020

Covid Economics, April 2020, with Martin Gonzalez-Eiras. PDF. We embed a lockdown choice in a simplified epidemiological model and derive formulas for the optimal lockdown intensity and duration. The optimal policy reflects the rate of time preference, epidemiological factors, the hazard rate of vaccine discovery, learning effects in the health care sector, and the severity of output losses due to a lockdown. In our baseline specification a Covid-19 shock as currently experienced by the...

Data and Research on the Coronavirus

The first of a long sequence of nice papers on the virus by economists are out: Martin Eichenbaum, Sergio Rebelo, and Mathias Trabandt (2020), The Macroeconomics of Epidemics. NBER wp 26882. (My comments on Twitter.) James Stock (2020), Coronavirus Data Gaps and the Policy Response to the Novel Corona Virus. Mimeo. Conclusion: There is an urgent need to reliably estimate the asymptomatic rate—the share among the infected who do not show strong symptoms. Data: Unconditional mortality rates...
