The Role of At-Home Work in the Pandemic-Era Revival of U.S. Productivity Growth
Abstract
Abstract: After growing at the dismal annual rate of 1.1 percent per year during the decadeof 2010-19, private-sector U.S. output per hour surged ahead in 2020-21 at an annual rate of
3.1 percent, faster even than achieved in the “dot.com” decade of 1995-2005. This paper
places this productivity growth revival into the context of previous business cycles by
developing a model of cyclical productivity behavior that highlights the countercyclical
behavior observed in 2008-2009 and again in 2020-2021. The paper develops a unique
quarterly database of productivity by industry and quantifies the role of shifts in output mix
toward industries with a higher level of productivity. Most of these high-productivity-level
industries were in the service sector and were characterized by work-at-home during the
two pandemic years, and their high productivity growth in those years contrasted with the
slow or negative productivity growth in “contact services” where workers had to be present
on the job. The results are complementary with recent survey research showing that at-
home workers reported being more productive at home and reported as well that they
worked at home during hours previously spent commuting.
