Does productivity or hours worked drive most U.S. output growth?
Core argument: Productivity grew more than four times as fast as hours worked in 2019–24 and roughly two and a half times as fast in 2007–19, with productivity outpacing hours growth in every period since 1990.
Since 1990, output growth at the macroeconomic level has come mostly from increases in productivity, rather than hours worked. Output growth decelerated from 2000 to 2007, and again from 2007 to 2019, but accelerated somewhat after 2019. Hours worked showed the most significant deceleration from 2000–07 and modest growth over the past two business cycles. The end dates for the periods on the chart align with business cycles. Overall, the chart displays a decelerating trend in the annual percent changes for output from 1990 to 2019, with a moderate resurgence, so far, after 2019. Productivity grew faster than hours worked in all periods. Hours growth flattened during the 2000–07 “jobless recovery,” after the “dot-com bust” recession. Productivity growth was responsible for nearly all output growth during this period. Finally, a weak but stable growth trend for hours worked appeared in the two periods from 2007–24. In the 2007–19 period, productivity grew roughly two and a half times as fast as hours worked. In the 2019–24 period, productivity then grew more than four times as fast as hours worked. However, productivity growth in the last two business cycles—so far—has remained a little slower than in the 1990–2007 periods.
