What Happened to the U.S. Economy during the 1918 Influenza Pandemic? A View Through High-Frequency Data

An economic downturn coincided with the start of the epidemic but the recession was short and moderate, compared with that of 1920/21. Cross-sectional high-frequency data indicate that the epidemic affected the labor supply sharply but briefly with no ensuing spill-overs; most of the recession, brief as it was, was due to the end of the war. I analyze weekly city-level mortality data and economic indicators with time series methods and structural estimation of an economic-epidemiological model: interventions to hinder the contagion reduced mortality at little economic cost, probably because reduced infections mitigated the impact on the labor force.
