Between 1990 and 1999, unit labor costs declined at an average annual rate of 2.0 percent or more in 8 of the service-producing industries measured by the Bureau of Labor Statistics.
The largest decreases in unit labor costs in the 1990-99 period were in variety stores (-5.7 percent per year), and radio, television, computer, and music stores (-5.6 percent). In an interesting contrast, the cost decline in variety stores was the result of a small decline in total compensation combined with an increase in output, while the cost decline in radio, television, computer, and music stores was the result of a significant rise in compensation being more than offset by increased output.
Other service-producing industries with substantial drops in labor costs were miscellaneous general merchandise stores (-3.5 percent per year), household appliance stores (-3.4 percent), used merchandise stores (-3.1 percent), retail nursery, lawn and garden supply stores (-2.8 percent), women’s clothing stores (-2.3 percent), and nonstore retailers (-2.0 percent).
Unit labor costs—the cost of the labor input required to produce one unit of output—are computed by dividing total compensation by real output.
