Learning from Experience: Why Nations May Have Responded Differently to COVID-19
Countries affected by the SARS pandemic in 2002-03 appear to have responded to COVID-19 more quickly and effectively with tests and mobility restrictions.

Social Distancing, Vaccination and Evolution of COVID-19 Transmission Rates in Europe
This paper provides estimates of COVID-19 transmission rates and explains their evolution for selected European countries since the start of the pandemic taking account of changes in voluntary and government-mandated social distancing, incentives to comply, vaccination and the emergence of new variants. Evidence based on panel data modeling indicates that the diversity of outcomes that we document may have resulted from the non-linear interaction of mandated and voluntary social distancing and the economic incentives that governments provided to support isolation. The importance of these ...

Work from Home After the COVID-19 Outbreak
Based on rich novel survey data, we document that 35.2 percent of the US workforce worked entirely from home in May 2020, up from 8.2 percent in February. Highly educated, high-income and white workers were more likely to shift to working from home and maintain employment following the pandemic. Individuals working from home daily before the pandemic lost employment at similar rates as daily commuters. This suggests that, apart from the potential for home-based work, demand conditions also mattered for job losses. We find that 71.7 percent of workers that could work from home effectively did ...

Observing Recent Trends in Job Postings
The number of job postings dropped considerably in the United States and the Fifth District in March and April but showed signs of recovery in May. A look at the data reveals how labor demand has varied by types of jobs amid the COVID-19 pandemic.
Reopening the U.S. Economy an Industry at a Time
A novel index of physical contact exposure helps to identify the industries that are the most contact-intensive and might reopen later, as well as lower-contact industries that could reopen sooner.

Weather, Social Distancing, and the Spread of COVID-19
Using high-frequency panel data for U.S. counties, I estimate the full dynamic response of COVID-19 cases and deaths to exogenous movements in mobility and weather. I find several important results. First, weather and mobility are highly correlated and thus omitting either factor when studying the COVID-19 effects of the other is likely to result in substantial omitted variable bias. Second, temperature is found to have a negative and significant effect on future COVID-19 cases and deaths, though the estimated effect is sensitive to which measure of mobility is included in the regression. ...

Social Distancing, Vaccination and Evolution of COVID-19 Transmission Rates in Europe
This paper provides estimates of COVID-19 effective reproduction numbers worldwide and explains their evolution for selected European countries since the start of the pandemic, taking account of changes in voluntary and government-mandated social distancing, incentives to comply, vaccination and the emergence of mutations. Evidence based on panel data modeling indicates that the diversity of outcomes that we document resulted from the non-linear interaction of mandated and voluntary social distancing and the economic incentives that governments provided to support isolation, with no one ...

Voluntary and Mandatory Social Distancing: Evidence on COVID-19 Exposure Rates from Chinese Provinces and Selected Countries
This paper considers a modification of the standard Susceptible-Infected-Recovered (SIR) model of epidemics that allows for different degrees of compulsory as well as voluntary social distancing. It is shown that the fraction of the population that self-isolates varies with the perceived probability of contracting the disease. Implications of social distancing both on the epidemic and recession curves are investigated and their trade off is simulated under a number of different social distancing and economic participation scenarios. We show that mandating social distancing is very effective ...

Impacts of COVID-19: Mitigation Efforts versus Herd Immunity
The rapid spread of COVID-19 is having devastating effects on the global economy. With death curves beginning to bend, governments will soon need to determine when and how to relax lockdown measures. The crucial question is: what are the public health consequences of reopening the economy? In this article, we argue that the observed decline in daily deaths could be due to two scenarios: social distancing measures and herd immunity. Both the widely used SIR model and the data collected thus far cannot distinguish these two scenarios. Such an identiļ¬cation problem generates a large degree of ...

The Hammer and the Scalpel: On the Economics of Indiscriminate versus Targeted Isolation Policies during Pandemics
We develop a simple dynamic economic model of epidemic transmission designed to be consistent with widely used SIR biological models of the transmission of epidemics, while incorporating economic benefits and costs as well. Our main finding is that targeted testing and isolation policies deliver large welfare gains relative to optimal policies when these tools are not used. Specifically, we find that when testing and isolation are not used, optimal policy delivers a welfare gain equivalent to a 0.6% permanent increase in consumption relative to no intervention. The welfare gain arises because ...
