PRODUCTIVITY AND COSTS: SERVICE-PRODUCING AND MINING INDUSTRIES, 
1987-98


	The Bureau of Labor Statistics of the U.S. Department of 
Labor reported today on labor productivity and unit labor cost 
changes for selected industries in the service-producing and 
mining sectors of the U.S. economy.  This is the first industry 
productivity news release to include unit labor costs, 
introduced by BLS in 1999 for these industries.  Labor 
productivity--defined as output per hour--rose for most of these 
industries in 1998.  Nearly half of the industries registering 
productivity growth also posted declines in unit labor costs.

	In 1998, labor productivity increased in 80 percent of the 
service-producing and mining industries reported here.  Output 
growth was recorded by 82 percent of the industries, while hours 
of labor grew in 54 percent of the industries.  The proportion 
of service-producing and mining industries experiencing long-term 
productivity growth was larger than the proportion with short-
term productivity growth.  Over the 1987-98 period, output per 
hour advanced in 92 percent of the service-producing and mining 
industries.  Output rose in 88 percent of the industries, while 
hours of labor grew in 64 percent of the industries.

	The attached tables present data for service-producing and 
mining industries for which BLS publishes productivity series at 
the 3-digit level of the Standard Industrial Classification 
(SIC) Manual.  Although the analysis that follows will focus on 
industries at the 3-digit level, BLS also publishes productivity 
series at the 2- and 4-digit level for these industries as well 
as for manufacturing industries.  (See section on �Productivity 
measurement� in the technical note.)

                         Retail trade

Current trends

	Productivity rose in 1998 in 25 of the 28 published 3-digit 
industries in retail trade.  The increases ranged from 0.1 
percent in new and used car dealers to 20.4 percent in radio, 
television, computer, and music stores.  The largest industries 
in retail trade, those with more than 2,400,000 employees, are 
eating and drinking places, grocery stores, and department 
stores.  In 1998, output per hour rose 0.6 percent in eating and 
drinking places, 1.1 percent in grocery stores, and 4.8 percent 
in department stores.  Productivity declined in only three 
retail trade industries reported here.  The three industries 
registering productivity declines were fuel dealers (-1.3 
percent), shoe stores (-5.0 percent), and retail bakeries
(-13.9 percent).

	Of the 25 industries in retail trade that recorded 
productivity growth, 13 also experienced decreases in unit labor 
costs in 1998.  The decreases in unit labor costs ranged from 
0.6 percent in nonstore retailers to 8.9 percent in radio, 
television, computer, and music stores.  Despite productivity 
growth, unit labor costs rose in the largest industries in 
retail trade--4.7 percent in eating and drinking places, 2.7 
percent in grocery stores, and 0.3 percent in department stores.  
All of the industries that experienced productivity declines 
also experienced increases in unit labor costs.

Long-term trends

	Although the proportion of retail trade industries with 
long-term productivity growth from 1987-98 was the same as the 
proportion with short-term productivity growth, the long-term 
rates tended to be lower than the 1998 rates.  Output per hour 
increased in 25 of the 28 industries during the 1987-98 period.  
Among these retail industries, labor productivity advanced at 
average annual rates exceeding 5.0 percent in five industries.  
An additional 13 industries registered annual growth rates in 
output per hour in the 2.0-5.0 percent range.

	Over the 1987-98 period, unit labor costs declined in 8 of 
the 28 retail trade industries.  The largest declines were in 
variety stores (-4.7 percent per year), radio, television, 
computer, and music stores (-3.5 percent per year), and 
household appliance stores (-2.2 percent per year).


                     Finance and services

Short-term trends

	In 1998, gains in output per hour were posted in eight of 
the nine industries in finance and services for which BLS 
published data at the 3-digit level.  The largest industry in 
terms of employment was hotels and motels, where productivity 
climbed 0.8 percent.  In the next largest industry, commercial 
banks, output per hour was virtually unchanged.

	The only declines in unit labor costs occurred in 
automotive repair shops (-1.0 percent) and funeral services and 
crematories (-2.0 percent) in 1998.  The largest industries in 
finance and services experienced rising unit labor costs.  Unit 
labor costs advanced 4.9 percent in hotels and motels and 8.6 
percent in commercial banks.

Long-term trends

	All nine industries in the finance and services sector 
registered long-term labor productivity growth.  From 1987 to 
1998, output per hour rose at an average annual rate of 0.8 
percent in hotels and motels and 2.6 percent in commercial 
banks.

	All but one of the nine industries in finance and services 
experienced rising unit labor costs.  Only barber shops posted a 
long-term decline in unit labor costs.  Unit labor costs 
decreased 0.9 percent per year in this industry.


        Transportation, communications, and utilities

Current trends

	Among the transportation industries with 1998 data included 
in this release, output per hour advanced 1.1 percent in the U.S. 
postal service, but fell in trucking (-1.8 percent) and in 
air transportation (-2.8 percent).  (See table 1.)  Productivity 
gains were recorded in two of the three communications 
industries, rising 6.4 percent in telephone communications and 
0.4 percent in cable and other pay TV services.  In contrast, 
productivity fell 0.3 percent in radio and television 
broadcasting.  In the utilities sector, output per hour climbed 
4.5 percent in electric utilities, but declined 3.3 percent in 
gas utilities.

	In 1998, unit labor costs fell 2.1 percent in telephone 
communications.  All other industries in the transportation, 
communications, and utilities sectors with 1998 data recorded 
rising unit labor costs.

	NOTE:  The most recent productivity and costs figures 
available for railroad transportation are for 1997.

Long-term trends

	Over the 1987-98 period, all of the industries in the 
transportation, communications, and utilities sectors posted 
gains in labor productivity with the exception of cable and 
other pay TV services.  (See table 2.)  The largest gains were 
in telephone communications (5.0 percent per year); electric 
utilities (4.2 percent per year); and gas utilities (4.0 percent 
per year).  The 1987-97 productivity gain in railroad 
transportation was 5.5 percent per year.

	Unit labor costs rose over the long term in all of the 
industries in the transportation, communications, and utilities 
sectors, except railroad transportation and telephone 
communications.


                       Mining

Current trends

	Productivity increased in 1998 in three of the five 3-digit 
mining industries reported here.  Declines in output per hour 
were recorded in copper ores (-1.1 percent) and in crushed and 
broken stone (-1.9 percent).

	Unit labor costs fell 0.4 percent in bituminous coal and 
lignite mining and 2.4 percent in copper ores in 1998.  
Increases in unit labor costs occurred in crude petroleum and 
natural gas (3.2 percent) and crushed and broken stone (9.1 
percent).

Long-term trends

	Over the 1987-98 period, all of the mining industries 
posted productivity gains.  The largest increase was in 
bituminous coal and lignite mining, 5.9 percent per year.
	The two mining industries with the fastest growth in 
productivity were the only ones to reduce unit labor costs.  
From 1987 to 1998, bituminous coal and lignite mining registered 
the largest reduction in unit labor costs, 2.9 percent per year.


Technical Note

Coverage

	In the service-producing sector, the BLS industry 
productivity series cover 100 percent of employment in 
retail trade, 90 percent in communications and utilities, 
57 percent in transportation, 17 percent in finance and 
services, and 2 percent in wholesale trade.  In the goods-
producing sector, the BLS industry productivity series 
cover 100 percent of employment in manufacturing and 96 
percent in mining; the construction sector is not covered.  
In the sectors with low coverage, a lack of adequate basic 
data and, in some cases, serious conceptual issues have 
prevented development of productivity measures.  (The 
coverage percentages noted here relate to unpublished as 
well as published series.  For information on series that 
do not meet BLS publication standards, see discussion
below.)

Revisions

	The data in this news release reflect revisions to 
series as published in table 42 of the Monthly Labor 
Review; in Unit Labor Costs for Selected Industries, 1987-
97, BLS Report 939, November 1999; and in Productivity by 
Industry: Service Sector and Mining, 1997, annual BLS news 
release.  The productivity series for the gas utilities 
industry (SIC 492,3PT) has been revised for the years 1967 
to 1997.  The revision is due to a change in the underlying 
data source.  Indexes of productivity by industry have been 
revised for the years 1993 to 1997 for most industries in 
the retail trade sector.  These revisions are due to the 
incorporation of annual sales data from the Census Bureau 
which were benchmarked to preliminary Census of Retail 
Trade data.  The revised series can be obtained in several 
ways: by visiting the Industry Productivity web site 
(http://stats.bls.gov/iprhome.htm); by calling the Division 
of Industry Productivity Studies (202-691-5618); or by 
sending a request by e-mail (dipsweb@bls.gov).

	Industry output indexes are prepared from basic data 
published by various public and private agencies, using the 
greatest level of detail available.  Data from the Bureau 
of the Census, U.S. Department of Commerce, are used 
extensively in developing output statistics for 
manufacturing, trade, and service-producing industries.  
All of the measures for 1998 in this news release are 
preliminary and subject to revision.

Productivity measurement

	The productivity measures in this release describe the 
relationship between output and the labor time involved in 
its production.  They show the changes from period to 
period in the amount of goods and services produced per 
hour.  Although these measures relate output to hours of 
employees or all persons engaged in an industry, they do 
not measure the specific contribution of labor, capital, or 
any other factor of production.  Rather, they reflect the 
joint effects of many influences, including changes in 
technology; capital investment; level of output; 
utilization of capacity, energy, and materials; the 
organization of production; managerial skill; and the 
characteristics and effort of the workforce.

	The reader should note that, occasionally, the year-
to-year movements in productivity measures might be 
somewhat erratic, particularly in the smaller industries.  
The annual changes in an industry's productivity are based 
on sample data, which are likely to differ from data 
generated by a census of establishments in the industry.  
As a result, long-term trends tend to be more reliable 
indicators of the performance of an industry than are the 
year-to-year changes.

Unit labor cost measurement

	The unit labor cost series in this release describe 
the cost of labor input required to produce one unit of 
output.  Unit labor costs are calculated as the ratio of 
current dollar labor compensation to constant dollar 
output.  The indexes of unit labor costs for each industry 
are computed by dividing an index of current dollar 
compensation by an index of constant dollar output.

	Compensation is a measure of the cost to the employer 
of securing the services of labor.  It is defined as 
payroll plus supplemental payments.  Payroll includes 
salaries, wages, commissions, dismissal pay, bonuses, 
vacation and sick leave pay, and compensation in kind.  
Supplemental payments are divided into legally required 
expenditures and payments for voluntary programs.  The 
legally required expenditures include employers� 
contributions to Social Security, unemployment insurance 
taxes, and workers� compensation.  Payments for voluntary 
programs include all programs not specifically required by 
legislation, such as the employer portion of private health 
insurance and pension plans.

	The indexes of industry output used in measuring labor 
productivity and unit labor costs are, wherever possible, 
calculated with a Tornqvist formula.  This formula 
aggregates the growth rates of the various industry 
products between two periods using the products� shares in 
industry value of production, averaged over the two 
periods, as weights.

	Published productivity and unit labor cost data for 
452 industries in the goods-producing and service-producing 
sectors are available on the Internet at 
http://stats.bls.gov/iprhome.htm.  Productivity series for 
an additional 222 industries have been withheld from 
publication because they do not meet BLS publication 
standards.  Among the unpublished industries are 32 
previously published industries.  An additional nine 
industries that were previously unpublished are now 
published, including computer and office equipment (SIC 
357) and electronic components and accessories (SIC 367).  
Unpublished data can be requested by phoning 202-691-5618 
or by sending e-mail to dipsweb@bls.gov.

Survey (CPS).  Other sources are:  the Association of American Railroads, the Department of Transportation, and the U.S. Postal Service.

budget.  FTE employee years are computed by dividing total hours of full-time, part-time, and intermittent workers by the number                                               
of hours in a standard work year.  The output and hours for SIC 431 reflect the Federal fiscal year.
