    PRODUCTIVITY AND COSTS
    First Quarter 2002


    The Bureau of Labor Statistics of the U.S. Department of Labor today
    reported revised productivity data--as measured by output per hour of all
    persons--for the first quarter of 2002. The revised seasonally adjusted
    annual rates of productivity change in the first quarter were:

    8.3 percent in the business sector and
    8.4 percent in the nonfarm business sector.

    In both sectors, the first-quarter productivity gains were slightly lower
    than those reported initially on May 7.

    In manufacturing, the revised productivity changes in the first quarter
    were:

    9.4 percent in manufacturing,
    13.3 percent in durable goods manufacturing, and
    4.6 percent in nondurable goods manufacturing.

    Manufacturing productivity rose as first-quarter output increased while
    hours of all persons working in the sector declined for the seventh
    consecutive quarter. Output and hours in manufacturing, which includes about
    16 percent of U.S. business-sector employment, tend to vary more from quarter
    to quarter than data for the more aggregate business and nonfarm business
    sectors. First-quarter measures are summarized in table A and appear in
    detail in tables 1 through 5.

    The data sources and methods used in the preparation of the
    manufacturing series differ from those used in preparing the business and
    nonfarm business series, and these measures are not directly comparable.
    Output measures for business and nonfarm business are based on measures of
    gross domestic product prepared by the Bureau of Economic Analysis of the
    U.S. Department of Commerce. Quarterly output measures for manufacturing
    reflect indexes of industrial production independently prepared by the Board
    of Governors of the Federal Reserve System. See Technical Notes for further
    information on data sources.

    Business

    Productivity increased 8.3 percent in the business sector (seasonally
    adjusted annual rate) from the fourth quarter of 2001 to the first quarter of
    2002, as output increased 6.2 percent and hours worked by all persons
    decreased 2.0 percent (table 1). The gain in output per hour was the largest
    since the first quarter of 1973, when growth was 8.4 percent.

    Hourly compensation increased 2.9 percent during the first quarter of
    2002. This measure of compensation includes wages and salaries, supplements,
    employer contributions to employee benefit plans, and taxes. Real hourly
    compensation, which takes into account changes in consumer prices, increased
    1.4 percent in the first quarter.

    Unit labor costs, which reflect changes in both hourly compensation and
    productivity, dropped 5.0 percent during the first quarter of 2002. The
    decline in unit labor costs was the largest since a fall of 7.5 percent in
    the first quarter of 1955. The implicit price deflator for business output,
    which reflects changes in both unit labor costs and unit nonlabor payments,
    was unchanged between the fourth quarter of 2001 and the first quarter of
    2002.

    Nonfarm business

    Productivity rose 8.4 percent in the nonfarm business sector during the
    first quarter of 2002, reflecting a 6.1-percent rise in output and a 2.1-
    percent decrease in working hours of all persons. The increase in output per
    hour was the largest since the second quarter of 1983, when growth was 9.9
    percent. Hours worked in the nonfarm business sector now have declined in
    seven of the last eight quarters (table 2).

    Hourly compensation increased 2.8 percent in the first quarter of 2002.
    When the rise in consumer prices is taken into account, real hourly
    compensation gained 1.4 percent in the first quarter.

    The 5.2-percent decrease in unit labor costs during the first quarter of
    2002 was the largest posted since the second quarter of 1983, when these
    costs fell 6.5 percent. The implicit price deflator for nonfarm business
    output declined 0.6 percent in the first quarter of 2002.
