PRODUCTIVITY AND COSTS
Fourth Quarter and Annual Averages 2009
Nonfarm business sector labor productivity increased at a 6.2 percent annual rate during the fourth quarter of 2009, the U.S. Bureau of Labor Statistics reported today. This gain in productivity reflects increases of 7.2 percent in output and 1.0 percent in hours worked. (All quarterly percent changes in this release are seasonally adjusted annual rates.) This was the first quarterly increase in hours worked since the second quarter of 2007 (0.9 percent). Productivity increased 5.1 percent over the last four quarters—more than during any similar period since output per hour rose 6.1 percent from the first quarter of 2001 to the first quarter of 2002 (chart 1, table A).
Labor productivity is calculated by dividing an index of real output by an index of the combined hours worked of all persons, including employees, proprietors, and unpaid family workers.
Unit labor costs in nonfarm businesses fell 4.4 percent in the fourth quarter of 2009, a result of the increase in productivity (6.2 percent) outpacing the increase in hourly compensation (1.5 percent). BLS defines unit labor costs as the ratio of hourly compensation to labor productivity; increases in hourly compensation tend to increase unit labor costs and increases in output per hour tend to reduce them. Over the last four quarters, unit labor costs declined 2.8 percent, as hourly compensation and productivity increased 2.2 percent and 5.1 percent, respectively (chart 2, table A). This decline in unit labor costs was the largest since unit labor costs fell 3.2 percent over the four quarters ending with the first quarter of 2002.
