What Explains the Post-2004 U.S. Productivity Slowdown?

Economic theory and history show that labour productivity growth is the main driver of rising living standards, so changes in the trend rate of productivity growth have profound implications for a society’s future prosperity. The average annual rate of business sector labour productivity growth in the United States declined by 1.9 percentage points between the 1995-2004 period and the 2004-2015 period, from 3.2 per cent to 1.3 per cent. This article summarizes the state of knowledge on the causes of the post-2004 slowdown in U.S. productivity growth. Official growth accounting estimates indicate that 60-65 per cent of the labour productivity decline is accounted for by a decline in total factor productivity growth, while 30-35 per cent is accounted for by a decline in the rate of capital deepening. Three industries account for over 80 per cent of the aggregate labour productivity decline: manufacturing, wholesale trade, and retail trade. The aggregate productivity slowdown is traceable to a decline in the productivity contributions arising from industries that produce or intensively use information and communication technology (ICT) products.
