In the nonfarm sector, unit labor costs fell at a seasonally adjusted annual rate of 2.5 percent in the fourth quarter. In manufacturing, unit labor costs dropped more rapidly, at a rate of 5.5 percent.
For the year, unit labor costs in the business nonfarm sector grew 1.7 percent in 1999, compared with 2.4 percent in 1998. In contrast, unit labor costs in the manufacturing sector fell 1.4 percent in 1999. Unit labor costs have declined in six of the last eight years in the manufacturing sector.
Unit labor costs—the cost of the labor input required to produce one unit of output—are computed by dividing labor costs in nominal terms by real output.
