The Impact of Health and Economic Policies on the Spread of COVID-19 and Economic Activity
This paper empirically investigates the causal linkages between COVID-19 spread, government health containment and economic support policies, and economic activity in the U.S. up to the introduction of vaccines in early 2021. We model their joint dynamics as generated by a structural vector autoregression and estimate it using U.S. state-level data. We identify structural shocks to the variables by making assumptions on their short-run relation consistent with salient epidemiological and economic features of COVID-19. We isolate the direct impact of COVID-19 spread and policy responses on ...

Pandemic Lockdown: The Role of Government Commitment
This paper studies lockdown policy in a dynamic economy without government commitment. Lockdown imposes a cap on labor supply, which improves health prospects at the cost of economic output and consumption. A government would like to commit to the extent of future lockdowns in order to guarantee an economic outlook that supports efficient levels of investment into intermediate inputs. However, such a commitment is not credible, since investments are sunk at the time when the government chooses a lockdown. As a result, lockdown under lack of commitment deviates from the optimal policy. Rules ...

Lockdowns and Innovation: Evidence from the 1918 Flu Pandemic
Does social distancing harm innovation? We estimate the effect of non-pharmaceutical interventions (NPIs)—policies that restrict interactions in an attempt to slow the spread of disease—on local invention. We construct a panel of issued patents and NPIs adopted by 50 large US cities during the 1918 flu pandemic. Difference-in-differences estimates show that cities adopting longer NPIs did not experience a decline in patenting during the pandemic relative to short-NPI cities, and recorded higher patenting afterward. Rather than reduce local invention by restricting localized knowledge ...

The Impact of Health and Economic Policies on the Spread of COVID-19 and Economic Activity
This paper empirically investigates the causal linkages between COVID-19 spread, government health containment and economic support policies, and economic activity during 2020 in the U.S. We model their joint dynamics as generated by a structural vector autoregression and estimate it using U.S. state-level data. We identify structural shocks to the variables by making assumptions on their short-run relation consistent with salient epidemiological and economic features of COVID-19. We isolate the direct impact of COVID-19 spread and policy responses on economic activity by controlling for ...

Four Stylized Facts about COVID-19
We document four facts about the COVID-19 pandemic worldwide relevant for those studying the impact of non-pharmaceutical interventions (NPIs) on COVID-19 transmission. First: across all countries and U.S. states that we study, the growth rates of daily deaths from COVID-19 fell from a wide range of initially high levels to levels close to zero within 20-30 days after each region experienced 25 cumulative deaths. Second: after this initial period, growth rates of daily deaths have hovered around zero or below everywhere in the world. Third: the cross section standard deviation of growth rates ...

What Happened to the US Economy During the 1918 Influenza Pandemic? A View Through High-Frequency Data
Burns and Mitchell (1946, 109) found a recession of "exceptional brevity and moderate amplitude." I confirm their judgment by examining a variety of high-frequency data. Industrial output fell sharply but rebounded within months. Retail seemed little affected and there is no evidence of increased business failures or stressed financial system. Cross-sectional data from the coal industry documents the short-lived impact of the epidemic on labor supply. The Armistice possibly prolonged the 1918 recession, short as it was, by injecting momentary uncertainty. Interventions to hinder the contagion ...

What Happened to the US Economy During the 1918 Influenza Pandemic? A View Through High-Frequency Data
Burns and Mitchell (1946, 109) found a recession of “exceptional brevity and moderate amplitude.” I confirm their judgment by examining a variety of high-frequency, aggregate and cross-sectional data. Industrial output fell sharply but rebounded within months. Retail seemed little affected and there is no evidence of increased business failures or stressed financial system. Cross-sectional data on manufacturing employment indicates that most of the recession, brief as it was, was due to the Armistice rather than the epidemic. Data from the nationwide coal industry documents the sharp but ...

Fight the Pandemic, Save the Economy: Lessons from the 1918 Flu
The COVID-19 outbreak has sparked urgent questions about the impact of pandemics, and associated countermeasures, on the real economy. Policymakers are in uncharted territory, with little guidance on what the expected economic fallout will be and how the crisis should be managed. In this blog post, we use insights from a recent research paper to discuss two sets of questions. First, what are the real economic effects of a pandemic—and are these effects temporary or persistent? Second, how does the local public health response affect the economic severity of the pandemic? In particular, do ...
