Economy Reached Trough in April 2020

The Business Cycle Dating Committee of the NBER, which maintains a chronology of the peaks and troughs in economic activity in the United States, has determined that a trough in monthly economic activity occurred in April 2020. The previous peak in economic activity occurred in February 2020, implying a two-month recession. The committee released a statement explaining the factors that contributed to this determination as well as a list of frequently asked questions related to the dating of business cycle peaks and troughs. For further information, please contact NBER's Director of Public Information, Charles A. Radin, or visit the Business Cycle Dating Committee page.


New Business Applications Surged during the Pandemic

The COVID-19 pandemic has led to restructuring in some parts of the US economy. Many businesses have closed, particularly in hard-hit sectors like entertainment, hospitality, and transportation. At the same time, entrepreneurs have been launching new businesses. In mid-2020, several months into the pandemic, the number of business startups reached an all-time peak. In a new research paper (28912), NBER Research Associate John Haltiwanger of the University of Maryland analyzes the Business Formation Statistics compiled by the US Census Bureau. He documents the sharp and sustained increase in new business registrations, and distinguishes between startups that are likely to hire employees and those that are not. Haltiwanger describes his findings in the video below, and explains that the surge in startups is a critical part of the reallocation of economic activity associated with the pandemic.

Two new working papers distributed this week report on the economic, health, and related consequences of the COVID-19 pandemic and public policies that respond to it. One presents evidence that social media advertisements by doctors and nurses, posted in late 2020, explaining the infection risks associated with holiday travel, reduced travel and subsequent infections (29021). The other tracks the incidence of anxiety and depression in the US population during the pandemic (29040).

More than 425 NBER working papers have addressed various aspects of the COVID-19 pandemic. These papers are open access and have been collected for easy reference. Like all NBER papers, they are circulated for discussion and comment, and have not been peer-reviewed. View them in reverse chronological order or by topic area.

NB20-01 figure
The number of applications and new awards for Social Security Disability Insurance (SSDI) rose during the Great Recession and earlier economic downturns. Some have speculated that this phenomenon could occur again during the COVID-19 crisis in the wake of pandemic-related job losses. While the relationship between economic conditions and SSDI awards is well-established, the reasons for it are less clear. One theory is that recessions worsen health, making more individuals...
