The data speak: Stronger pandemic response yields better economic recovery

With much of the U.S. in shutdown mode to limit the spread of the Covid-19 disease, a debate has sprung up about when the country might Âreopen commerce, to limit economic fallout from the pandemic. But as a new study co-authored by an MIT economist shows, taking care of public health first is precisely what generates a stronger economic rebound later.

The study, using data from the flu pandemic that swept the U.S. in 1918-1919, finds cities that acted more emphatically to limit social and civic interactions had more economic growth following the period of restrictions.

Indeed, cities that implemented social-distancing and other public health interventions just 10 days earlier than their counterparts saw a 5 percent relative increase in manufacturing employment after the pandemic ended, through 1923. Similarly, an extra 50 days of social distancing was worth a 6.5 percent increase in manufacturing employment, in a given city.

ÂWe find no evidence that cities that acted more aggressively in public health terms performed worse in economic terms, says Emil Verner, an assistant professor in the MIT Sloan School of Management and co-author of a new paper detailing the findings. ÂIf anything, the cities that acted more aggressively performed better.Â

With that in mind, he observes, the idea of a Âtrade-off between public health and economic activity does not hold up to scrutiny; places that are harder hit by a pandemic are unlikely to rebuild their economic capacities as quickly, compared to areas that are more intact.

ÂIt casts doubt on the idea there is a trade-off between addressing the impact of the virus, on the one hand, and economic activity, on the other hand, because the pandemic itself is so destructive for the economy, Verner says.

The study, ÂPandemics Depress the Economy, Public Health Interventions Do Not: Evidence from the 1918 Flu, was posted to the Social Science Research Network as a working paper on March 26. In addition to Verner, the co-authors are Sergio Correia, an economist with the U.S. Federal Reserve, and Stephen Luck, an economist with the Federal Reserve Bank of New York.

Evaluating economic consequences

To conduct the research, the three scholars examined mortality statistics from the U.S. Centers for Disease Control (CDC), historical economic data from the U.S. Census Bureau, and banking statistics compiled by finance economist Mark D. Flood, using the ÂAnnual Reports of the Comptroller of Currency, a government publication.

As Verner notes, the researchers were motivated to investigate the 1918-1919 flu pandemic to see what lessons from it might be applicable to the current crisis.

ÂThe genesis of the study is that weÂre interested in what the expected economic impacts of todayÂs coronavirus are going to be, and what is the right way to think about the economic consequences of the public health and social distancing interventions weÂre seeing all around the world, Verner says.

Scholars have known that the varying use of Ânonpharmaceutical interventions, or social-distancing measures, correlated to varying health outcomes across cities in 1918 and 1919. When that pandemic hit, U.S. cities that shut down schools earlier, such as St. Louis, fared better against the flu than places implementing shutdowns later, such as Philadelphia. The current study extends that framework to economic activity.

Quite a bit like today, social distancing measures back then included school and theater closures, bans on public gatherings, and restricted business activity.

ÂThe nonpharmaceutical interventions that were implemented in 1918 interestingly resemble many of the policies that are being used today to reduce the spread of Covid-19, Verner says.

Overall, the study indicates, the economic impact of the pandemic was severe. Using state-level data, the researchers find an 18 percent drop in manufacturing output through 1923, well after the last wave of the flu hit in 1919.

Looking at the effect across 43 cities, however, the researchers found significantly different economic outcomes, linked to different social distancing policies. The best-performing cities included Oakland, California; Omaha, Nebraska; Portland, Oregon; and Seattle, which all enforced over 120 days of social distancing in 1918. Cities that instituted fewer than 60 days of social distancing in 1918, and saw manufacturing struggle afterward, include Philadelphia; St. Paul, Minnesota; and Lowell, Massachusetts.

ÂWhat we find is that areas that were more severely affected in the 1918 flu pandemic see a sharp and persistent decline in a number of measures of economic activity, including manufacturing employment, manufacturing output, bank loans, and the stock of consumer durables, Verner says.

Banking issues

As far as banking goes, the study included banking write-downs as an indicator of economic health, because Âbanks were recognizing losses from loans that households and businesses were defaulting on, due to the economic disruption caused by the pandemic, Verner says.

The researchers found that in Albany, New York; Birmingham, Alabama; Boston; and Syracuse, New York  all of which also had fewer than 60 days of social distancing in 1918  the banking sector struggled more than anywhere else in the country.

As the authors note in the paper, the economic struggles that followed the 1918-1919 flu pandemic reduced the ability of firms to manufacture goods  but the reduction in employment meant that people had less purchasing power as well.

ÂThe evidence that we have in our paper  suggests that the pandemic creates both a supply-side problem and a demand-side problem, Verner notes.

As Verner readily acknowledges, the composition of the U.S. economy has evolved since 1918-1919, with relatively less manufacturing today and relatively more activity in services. The 1918-1919 pandemic was also especially deadly for prime working-age adults, making its economic impact particularly severe. Still, the economists think the dynamics of the previous pandemic are readily applicable to our ongoing crisis.

ÂThe structure of the economy is of course different, Verner notes. However, he adds, ÂWhile one shouldnÂt extrapolate too directly from history, we can learn some of the lessons that may be relevant to us today. First among those lessons, he emphasizes: ÂPandemic economics are different than normal economics.Â
