The U.S. Commerce Department’s National Bureau of Economic Research (NBER) published a study in its October 2022 bulletin which showed that labor productivity growth in the American economy averaged just 1.1% per year from 2010-2019, a period in which China’s economic productivity growth, for example, was 3.9% per year. The well-known American economist Robert Gordon (The Rise and Fall of American Prosperity) participated in the study. (https://www.nber.org/digest/202210/productivity-growth-and-during-pandemic)
As of 2022, however, U.S. productivity growth was clearly negative throughout the year; the Labor Department reported Nov. 3 that productivity dropped by more than 1.0% year-on-year in all three quarters of the year thus far, the first time this has happened in 40 years, despite strong fluctuations of employment rates during those decades.
