US productivity growth slows to 2.2 per cent rate in Q3
WASHINGTON — U.S. productivity grew at an annual rate of 2.2 per cent in the third quarter, a slowdown from the previous quarter but still better than the lacklustre gains of the last decade. Labor costs accelerated but remained at a low level.
The rise in productivity in the July-September period followed a 3 per cent rate of increase in the second quarter, which had been the strongest figure in three years. Labor costs rose at a 1.2 per cent rate after having fallen at a 1 per cent rate in the second quarter.
Productivity, the amount of output per hour of work, has been weak throughout the current recovery that began in June 2009. Analysts have been unable to come up with definitive reasons for the slowdown.
Productivity last year rose by just 1.1 per cent. Over the past decade, productivity has been up at an average annual rate of 1.3 per cent, just about half the 2.1 per cent gains seen in the seven decades starting in 1947. The period from 2000 to 2007 saw even stronger annual gains of 2.7 per cent, a burst that was credited to efficiency improvements achieved with the introduction of high-tech computers and other devices to the workplace.
