MULTIFACTOR PRODUCTIVITY TRENDS, 1999

Private Business, Private Nonfarm Business, and Manufacturing
(Incorporating Corrected Estimates for Manufacturing)

From 1998 to 1999, multifactor productivity rose 0.8 percent in the private 
business sector and 0.6 percent in the private nonfarm business sector, the 
Bureau of Labor Statistics of the U.S. Department of Labor reported. 

Multifactor productivity is designed to measure the joint influences on 
economic growth of technological change, efficiency improvements, returns to
scale, reallocation of resources, and other factors.  Multifactor productivity,
therefore, differs from the labor productivity (output per hour) measures that
are published quarterly by BLS since it requires information on capital 
services and other data that are not available on a quarterly basis.  

Multifactor productivity increased for the eighth consecutive year in both the 
private business and private nonfarm business sectors, but at the lowest rates
since 1995.  The 1999 annual changes are summarized in tables A and C; further
detail and historical measures are shown in tables 1 through 9.

-------------------------------------------------------------------------------
This news release corrects errors in multifactor productivity published in 
USDL 01-82 on April 10, 2001.  The errors were confined to measures for the 
manufacturing sector and manufacturing industries.  The 1999 data for 
manufacturing output and materials were incorrect because of a programming 
error.  There were also errors in the 1990-1995 trends in manufacturing for
all variables in table C due to a posting error.  The errors did not affect
any data for private business or private nonfarm business, nor did they 
affect any data in the Productivity and Cost news releases.
-------------------------------------------------------------------------------

In manufacturing, the increase in multifactor productivity for 1998-1999 was
2.9 percent.  Multifactor productivity increased for the eighth consecutive
year in manufacturing.  In five of the last six years, productivity has
advanced at the relatively rapid rate of at least 2 percent per year, a faster
rate than in earlier periods (see table C). 


The data sources and methods used in the preparation of the manufacturing 
series differ from those used in preparing the private business and private 
nonfarm business series, and these measures are not directly comparable.  See
page 8 and the Summary of Methods for further information on data sources and
methods.

Chart 1 shows the annual indexes of multifactor productivity, output per hour
worked, and output per unit of capital services for 1948-1999 for the private 
business sector.  Over the last 50 years, capital services have grown more 
rapidly than hours in the private business sector.  The skills of workers as
measured by their education and worker experience have also risen over this 
period.  These shifts toward more capital intensive production and to workers
with more human capital have supplemented multifactor productivity growth.  As 
a result, output per hour has usually grown at a faster rate than multifactor 
productivity.  However, short-term fluctuations of multifactor productivity and
output per hour generally move in the same direction. 


Private business and private nonfarm business

In private business and private nonfarm business, the change in multifactor
productivity reflects the difference between the change in real gross domestic 
product for the sector and the change in labor and capital inputs engaged in 
the production of this output.  The output measures for private business and 
private nonfarm business are similar to the indexes of output for business and
nonfarm business used in the quarterly labor productivity measures, but omit
the output of government enterprises.  

A change in multifactor productivity reflects the change in output that cannot
be accounted for by the change in combined inputs of labor and capital.  In 
contrast, a change in labor productivity reflects the change in output that 
cannot be accounted for by the change in hours of all persons engaged in
production.

Changes in 1998-99

Private business sector

Multifactor productivity rose 0.8 percent in 1999, the lowest rate of increase
since 1995.  Multifactor productivity has not declined since the recession year
of 1991.  The multifactor productivity gain in 1999 reflected a 4.8 percent 
increase in output and a 3.9 percent increase in the combined inputs of capital
and labor.  By comparison, in 1998, the rate of increase was 5.1 percent in 
output and 3.6 percent in combined inputs. 

In 1999, capital services grew by 6.4 percent, while labor input grew by 2.7
percent.  The disparity between capital services growth and labor input growth
was the largest since 1982 (table 4).  In fact, capital services showed the
steepest gain since the time series started in 1948-49.  Equipment and 
inventories grew more rapidly than the other asset categories (table 7).  
Equipment posted its largest growth rate ever, 11.6 percent, since 1949.  
The growth in equipment has accelerated during the entire 1992-99 period.  

Labor input in 1999 continued to grow faster than the average for the 1990s. 
The growth rate of labor input reflects the growth rate of hours at work, 
adjusted for the effects of changing labor composition.  Changes in hours at
work reflect the combined effects of changes in the average work week and 
employment.  In previous years, labor input followed a pattern of small 
declines in the work week and modest increases in labor composition.  Labor 
input in 1999, however, reflected small increases in the work week as well as 
relatively large increases in labor composition.  Employment continues to be 
the principal source of labor input growth.  Employment rose 1.8 percent in
1999, accounting for two-thirds of the increase in labor input.  

Unlike multifactor productivity, labor productivity continued to grow at almost
the same rate in 1999 as in 1998.  Labor productivity (output per hour worked)
increased 2.7 percent in 1999.  Capital productivity (output per unit of 
capital services) fell 1.6 percent, the lowest rate since 1991.  Capital
services per hour jumped 4.3 percent, the largest gain since 1991.

	Private nonfarm business

Multifactor productivity in the private nonfarm business sector increased by
0.6 percent in 1999.  This was the eighth consecutive year of growth, but the 
lowest rate since 1995.  Output showed a 4.7 percent rate of growth.  The 
growth of combined units of capital and labor inputs was 4.1 percent.  By
comparison, in 1998, the rate of increase was 5.2 percent in output and 3.7 
percent in combined inputs. Labor input grew 2.9 percent in 1999; a little
more than two-thirds of this growth was due to increased employment.  Capital 
services growth continued to accelerate, increasing 6.6 percent in 1999, the
largest gain since the series began in 1948. The fastest growing component of
capital services was equipment, which posted its steepest gain ever (table 8).

Labor productivity grew 2.5 percent in 1999.  Capital productivity dipped 1.8 
percent.  In 1999, capital services per hour increased at its highest rate
since 1991, posting a 4.3 percent gain.


Long-term trends in private business and private nonfarm business

Labor productivity (output per hour) differs from multifactor productivity 
(output per unit of combined capital and labor inputs) in the treatment of 
both capital and hours.  Labor productivity measures do not explicitly account
for the effects of capital or of changes in the composition of labor on output 
growth.  As a result, changes in capital intensity (the capital-hours ratio) 
and labor composition can influence labor productivity growth.  In contrast, 
multifactor productivity treats capital as an explicit factor of production,
and, therefore, is net of changes in capital intensity.  In addition, the labor
input measure used to calculate multifactor productivity reflects the combined
effects of changes in hours at work and of shifts in the educational attainment
and in the experience of the work force.  Therefore, multifactor productivity 
accounts for changes in labor composition as well.  Long-term labor 
productivity growth can be viewed as the sum of three components: multifactor
productivity growth, the contribution of increased capital intensity, and the
contribution of shifts in labor composition (table B and chart 2).

The contribution of capital intensity equals the change in the capital-hours
ratio multiplied by capital's share of total payments to inputs.  The 
contribution of labor composition equals the difference between the growth 
rate of labor input and the growth rate of hours multiplied by labor's share
of total payments.  Historically, capital's share has been slightly less than
one-third of the total payments.

From 1948 to 1999, output per hour grew at an annual rate of 2.5 percent in
private business (table B).  Of the 2.5 percent growth rate in labor
productivity, 1.4 percent can be attributed to increases in multifactor
productivity, 0.8 percent to the contribution of capital intensity, and 0.2
percent to changes in labor composition.  The contribution of capital intensity 
is composed of the contribution of information processing equipment and
software and of the contribution of other types of capital.  Information
processing equipment and software is composed of computers and related 
equipment, communications equipment, instruments and photocopying equipment,
and software.  Investment in these forms of capital were small prior to 
1979 but has grown to nearly half of all investment in recent years. 

From 1948 to 1973, multifactor productivity grew at an average annual rate of
2.1 percent in private business.  This rate, combined with the 1.0 percent 
contribution of capital intensity and the 0.2 percent contribution of labor 
composition, resulted in a labor productivity growth rate of 3.3 percent in 
private business.

Table B and chart 2 show the post-1973 slowdown.  During 1973 to 1979, gains in 
multifactor productivity slowed to 0.6 percent per year in private business.
At the same time, the average annual contribution of capital intensity to 
labor productivity growth decreased to 0.7 percent, and labor composition made
no contribution.  Labor productivity, therefore, increased 1.3 percent per year 
from 1973 to 1979.

Between 1979 and 1990, labor productivity increased 1.6 percent, slightly
faster than the 1.3 percent growth in the 1973-79 period, but still a 
relatively slow rate of growth.  All of the faster labor productivity growth 
was the result of changes in the composition of the work force, which went from
a 0.0 percent rate in 1973-79 to a 0.3 percent rate of growth for 1979-90.  
Information processing capital began to play an increasingly important role 
during this period.  These forms of capital contributed 0.5 percent per year to
labor productivity growth, or nearly three-quarters of the 0.8 percent growth
in the contribution of all capital services. 

From 1990 to 1995, labor productivity advanced at an annual rate of 1.5 percent 
in the private business sector.   This was 0.1 percentage point less than in 
the 1979-90 period.   The slower rate of growth was due to the decline in the
rate of growth of the contribution of capital services, from 0.8 percent in 
1979-90 to 0.5 percent in 1990-95.  This lower rate of growth offset small 
increases in the rate of growth in multifactor productivity and in the 
contribution of labor composition for this period.  Information processing
capital became increasingly important during the 1990-95 period.  During this 
period, information processing equipment contributed 0.4 percent per year to
labor productivity growth, or 80 percent of the contribution of all capital.

5. Output per unit of combined labor and capital inputs.

Note: The sum of multifactor productivity and the contributions 
may not equal labor productivity due to independent rounding.


During 1995-99, output per hour grew 2.6 percent per year in private business,
1.1 percentage points faster than during the 1990-95 period.  Most of the 
larger growth can be attributed to faster multifactor productivity growth, 
which more than doubled from 0.6 percent to 1.3 percent per year.  Larger
contributions from information processing capital account for the remainder of
the increase.  Continuing the trend in substitution of information processing 
equipment for other forms of capital, information capital accounted for 90 
percent of the contribution of all capital.   

The trends of the various measures in the private nonfarm business sector were
similar to those in the private business sector in each period.  So, the
pattern of productivity slowdowns after 1973 and recoveries after 1979 seen in
private business can also be seen in the private nonfarm business sector.


Contribution of research and development to multifactor productivity in private 
nonfarm business

While multifactor productivity reflects many influences, technological change
is one of the primary contributors.  For private nonfarm business, BLS also
reports estimates of the impact on multifactor productivity growth from the 
effects of firms' spending for research and development (R&D) on all firms 
within the same industries.  Because many people associate research and 
development spending and the resulting technological improvements with 
productivity, multifactor productivity has not been adjusted to exclude the 
effects of research and development.  The contribution of research and 
development averaged 0.2 percent per year for the entire 1948-99 period, or 
nearly 15 percent of total multifactor productivity growth (table B).  
The contribution of research and development was 0.2 percent per year during
the 1948-73 period, slowing to 0.1 percent during the 1973-79 period and
returning to 0.2 percent for the periods 1979-90, 1990-95, and 1995-99. 

Manufacturing 

The multifactor productivity measures for manufacturing differ in several ways
from those for private business and private nonfarm business in their treatment
of labor input, output, and classes of factor inputs.  First, the manufacturing
measure of labor input is a direct aggregate of hours.  This is in contrast to
the major sector measures for which estimates of the effects of changing labor 
composition have been developed. 

Additionally, the output concept used for multifactor productivity in
manufacturing is "sectoral output."  Sectoral output is similar to gross 
output, but excludes shipments from one manufacturing establishment to another.
The resulting multifactor productivity measure compares production in the
manufacturing sector for use outside of manufacturing with the inputs used in
the manufacturing process obtained from outside of manufacturing.  The
comparison excludes flows between manufacturing establishments from measures of
both output and inputs.  

Finally, multifactor productivity in manufacturing compares "sectoral output" 
to three classes of inputs: 1) hours at work of labor employed within
manufacturing; 2) capital services employed by manufacturing establishments;
and 3) purchases of energy, materials, and business services from outside of 
manufacturing (intermediates). 

In manufacturing, intermediates are the largest input in terms of costs.
Furthermore, research has shown that substitution among inputs, including 
intermediates, affects productivity change.  It is therefore important to 
include intermediates in productivity measures at the level of manufacturing.
In contrast, the more aggregate productivity measures compare "value-added" 
output with two classes of inputs, capital and labor.  Because of these 
differences in methods, productivity change in manufacturing cannot be directly
compared with changes in private business or private nonfarm business.  


Manufacturing productivity in 1999 and historical trends

Multifactor productivity in manufacturing rose 2.9 percent in 1999 (table C).
This was about the same rate as the 2.6 percent gain in 1998.  Multifactor
productivity grew 2 per cent or more in five of the last six years.  These 
rates are much faster than the 1.2 percent per year rate averaged over the 
1949-99 period. 

In 1999, the 2.9 percent gain in multifactor productivity was the result of a 
3.7 percent advance in sector output less a 0.7 percent increase in combined
inputs.  Growth in output and combined inputs slowed markedly in 1999. 
Combined inputs growth was the slowest since a decline in 1991.  Energy input 
grew for a second year in a row, rising 2.8 percent in 1999.  Inputs 
of materials rose 0.3 percent in 1999, the smallest increase since a decline
in 1987.  Capital services continued to accelerate, posting a 5.2 percent 
advance, the largest increase since 1974.  Hours fell for the second year in a
row, declining 0.8 percent, the largest decline in hours since 1991. 

Multifactor productivity grew 1.2 percent annually from 1949 to 1999 (when the 
manufacturing series started).  Sectoral output increased at a 3.3 percent 
annual rate, and combined inputs rose 2.1 percent per year (table C).  Unlike
the private business and private nonfarm business sectors, the productivity
slowdown in manufacturing was confined to the 1973-79 period.  Multifactor
productivity, which had been growing 1.5 percent annually prior to 
1973, fell 0.6 percent per year between 1973 and 1979.   Output growth slowed
to 2.5 percent, while combined inputs grew 3.1 percent over the 1973-79 time 
period.

From 1979 to 1990, multifactor productivity growth in manufacturing rebounded
sharply to 1.1 percent per year.  Sectoral output growth continued to slow,
and, in this period, all input growth rates also fell.  Hours declined, and 
the growth rates for both capital services and materials fell sharply.  As a 
result, combined inputs grew less than 1 percent annually.  The rebound in 
productivity was associated mainly with slower growth in combined inputs.

From 1990 to 1995, multifactor productivity growth advanced at about the same
rate as in the previous decade.  Multifactor productivity increased 1.2 percent 
per year during this period.  Output growth increased to 3.1 percent per year,
while combined inputs rose 1.8 percent annually.  Hours declined 0.1 percent, 
less than in the previous period, and energy, materials, and purchased business
services all grew much more rapidly than in the 1979-90 period.

From 1995 to 1999, the multifactor productivity growth rate doubled to 2.5
percent per year.  Sectoral output growth increased to 4.5 percent per year, 
while combined inputs continued to advance at about the same rate as in the 
early 1990s.  Hours increased slightly during the 1995-99 period, but the 
increase in the growth rate of capital services, to 4.4 percent, was most 
notable.  


Among detailed manufacturing industries, durable goods manufacturers 
experienced considerably faster multifactor productivity gains than nondurable 
goods manufacturers (table 9).  While little difference existed prior to 1979, 
the productivity gap widened thereafter, primarily due to the rapid 
productivity growth in the two machinery industries: industrial and commercial 
machinery and electronic and other electrical equipment.

Over the 1949-99 period, multifactor productivity advanced most rapidly in 
electronic and other electrical equipment, textile mill products, and
industrial machinery.  The printing and publishing industry was the only 
industry to experience a decline in multifactor productivity over the entire 
period.  In the more recent period of 1995-99, multifactor productivity in
electronic and other electrical equipment advanced 8.1 percent per year and it
rose 6.9 percent per year in industrial machinery.  Most information processing
equipment is made within these two industries. 


Revisions

The multifactor productivity data for 1998 and earlier years issued on Sept. 21,
2000, incorporated definition and classification changes in the National Income
and Product Accounts (NIPAs).  The data issued today reflect a number of 
revisions to source data. 

Private business and private nonfarm business output series reflect the
annual revisions to the NIPAs, announced by the Bureau of Economic Analysis in 
August 2000.

The hours data in this release incorporate the results of the 1999 Hours at
Work survey.  This survey is designed to measure the ratio of hours at work to
hours paid for production and nonsupervisory employees in nonagricultural
establishments.  BLS converts hours paid from the Current Employment Statistics
program to hours at work using data from this survey.  The results from the

Summary of Methods

    The following note describes the major data sources and the procedures 
used in deriving BLS multifactor productivity indexes.  More detailed 
information on methods, limitations, and data sources is provided in BLS 
Bulletin 2178 (September 1983), "Trends in Multifactor Productivity, 
1948-81."  Methods for measuring manufacturing multifactor productivity 
are discussed in William Gullickson, "Measurement of productivity growth in 
U.S. manufacturing," in the July 1995 issue of the Monthly Labor Review.  
Additional data not contained in the release can be obtained in print or 
at http://stats.bls.gov/mprhome.htm.

    This release presents data for the private business, private nonfarm 
business, and manufacturing sectors.  The private business sector, which 
accounts for about 76 percent of gross domestic product, includes all of 
gross domestic product except the output of general government, government 
enterprises, non-profit institutions, the rental value of owner-occupied 
real estate, and the output of paid employees of private households.  
Additionally, the private nonfarm business sector excludes farms, but 
includes agricultural services.  Manufacturing sector output is measured as 
the value of all production delivered to non-manufacturing industries plus 
deliveries to final demand.  

    The private business, private nonfarm business, and manufacturing 
multifactor productivity measures describe the relationship between output in 
real terms and the inputs involved in its production.  They do not measure 
the specific contributions of labor, capital, or any other factor of 
production.  Rather, multifactor productivity is designed to measure the 
joint influences on economic growth of technological change, efficiency 
improvements, returns to scale, reallocation of resources due to shifts in 
factor inputs across industries, and other factors.

Private business and private nonfarm business 

    The multifactor productivity indexes for private business and private 
nonfarm business are derived by dividing an output index by an index of 
labor input and capital services.  The output indexes are computed as chained 
superlative indexes (Fisher Ideal indexes) of components of real output.  
For the years 1948 to 1999, the Bureau of Economic Analysis (BEA) supplies 
the output indexes.  BLS adjusts these to eliminate the output of government 
enterprises.

    Capital input measures the services derived from the stock of physical 
assets and software.  The assets included are fixed business equipment, 
structures, inventories, and land.  Among equipment, BLS provides additional 
detail for information processing equipment and software (IPES).  IPES is 
composed of four broad classes of assets: computers and related equipment, 
software, communications equipment, and other IPES equipment.  Computers and 
related equipment includes mainframe computers, personal computers, printers, 
video displays, and other related equipment.  Software is comprised of 
pre-packaged, custom, and own-account software.  Communications equipment is 
not further differentiated.  Other IPES includes scientific and related 
equipment, photocopying and related equipment, and office and accounting 
equipment.  Structures include nonresidential structures and residential 
capital that is rented out by profit-making firms or persons.  Financial 
assets are excluded, as are owner-occupied residential structures.  The 
aggregate capital measures are obtained by Tornqvist aggregation of the 
capital stocks for each asset type within each of 53 industries using 
estimated rental prices for each asset type.  Each rental price reflects the 
nominal rate of return to all assets within the industry and rates of 
economic depreciation and revaluation for the specific asset; rental prices 
are adjusted for the effects of taxes.  Data on investments in physical 
assets are obtained from BEA.  Current-dollar gross product originating (GPO) 
data, obtained from BEA, are used in estimating capital rental prices.  
This news release makes use of revised GPO data, released by BEA in 
December 2000.

    Labor input in private business and private nonfarm business is obtained 
by Tornqvist-aggregation of the hours worked by all persons, classified by 
education, work experience, and gender with weights determined by their 
shares of labor compensation.  Hours paid of employees are obtained from the 
Current Employment Statistics program.  The hours at work of proprietors, 
unpaid family workers, and farm employees are derived from the Current 
Population Survey.  The hours of employees are converted to an at-work basis 
by using the Hours at Work survey.  The growth rate of labor composition is 
defined as the difference between the growth rate of weighted labor input and 
the growth rate of the hours of all persons. Additional information 
concerning data sources and methods of measuring labor composition can be 
found in BLS Bulletin 2426 (December 1993), "Labor Composition and U.S. 
Productivity Growth, 1948-90."

    The labor and capital components of the input indexes are combined with 
(Tornqvist) weights that represent each component's share of total costs.  
Total costs are defined as the value of output (gross product originating) 
less a portion of indirect business taxes.  Most indirect taxes, such as 
excise taxes, are excluded from costs; however, property and motor vehicle 
taxes remain in total costs.  The index uses changing weights: The share in 
each year is averaged with the preceding year's share.

Manufacturing sector and manufacturing industries

    The manufacturing multifactor productivity index is derived by dividing an 
output index by an index of combined hours, capital services, energy, 
materials, and purchased business services.  The output index for total 
manufacturing is computed using a chained superlative index (Tornqvist) of 
4-digit SIC industry outputs.  Industry outputs are developed by BLS from 
data obtained from the Annual Survey of Manufactures (ASM) and the Census of 
Manufactures (CM) from the Bureau of the Census, U.S. Department of Commerce, 
together with Producer Price Indexes from BLS and price data from BEA.  

    Labor input in manufacturing is measured as the sum of hours at work of 
all persons.  The construction of hours at work follows the methods used in 
the private business sector described above, except that hours in 
manufacturing are directly aggregated and do not include the effects of 
changing labor composition. Capital inputs in manufacturing are measured 
using the same methods and data sources as capital services in private 
business. 

    Energy input is constructed using costs and quantity data from the ASM, 
the CM, and the Manufacturing Energy Consumption Survey of the Energy 
Information Administration, U.S. Department of Energy, together with BLS 
Producer Price Indexes.  The series on non-energy materials input also relies 
on ASM and CM data.  Indexes of purchased business services are developed by 
BLS using input-output tables to estimate the proportion of costs attributed 
to nine types of services.  Tornqvist indexes of each of these three input 
classes are developed at the 2-digit SIC level and then aggregated to total 
manufacturing.  As with the sectoral output measures, materials and energy 
inputs are adjusted to exclude transactions between establishments within 
the same sector.

     The five input indexes (capital services, hours, energy, materials, and 
purchased business services) are combined using Tornqvist aggregation, 
employing weights that represent each component's share of total costs.  
Total costs are defined as the value of manufacturing sectoral output.  
The index uses changing weights: The share in each year is averaged with 
the preceding year's share.

Research and development

     The stock of research and development in private nonfarm business is 
derived by cumulating constant dollar measures of research and development 
expenditures and allowing for depreciation.  Current dollar expenditures for 
privately-financed research and development for the years 1953-99 are 
obtained from annual issues of Research and Development in Industry published 
by the National Science Foundation.  BLS develops price deflators and 
estimates of the rate of depreciation.  Further description of these data and 
methods can be found in BLS Bulletin 2331 (September 1989), "The Impact of 
Research and Development on Productivity Growth."

(1) The private business sector includes all of gross domestic product except 
    the output of general government, government enterprises, non-profit 
    institutions, the rental value of owner-occupied real estate, and the 
    output of paid employees of private households. The private nonfarm 
    business sector also excludes farms but includes agricultural services.

(2) Output per unit of combined labor and capital inputs.

(3) Gross domestic product originating in the sector, 
    superlative chained index.

(4) Index of the hours at work of all persons including employees, 
    proprietors, and unpaid family workers classified by education, work 
    experience, and gender.  This superlative chain index is computed by 
    combining changes in the hours of each education, experience, 
    and gender group weighted by each group's share of labor compensation. 

(5) A measure of the flow of capital services used in the sector.

(6) Labor input combined with capital input, using labor's and capital's 
    shares of costs as weights to form a superlative chained index. 

(7) Sectoral output per combined units of capital, hours, energy, 
    non-energy materials, and purchased business services.

(8) Manufacturing gross output excluding transactions between manufacturing
    establishments, superlative chained index.

(9) Hours at work of all persons.

(10) Combined units of capital services, hours, energy, non-energy materials, and 
     purchased business services, superlative chained index.

N.A. - Multifactor productivity measures are not published because of the 
       small size of the industry and data limitations.  This industry is 
       included in the aggregate for total manufacturing.

Note:  Multifactor productivity measures by industry are not directly 
       comparable to measures for aggregate manufacturing because industry 
       measures exclude transactions only within the specific industry while 
       the aggregate manufacturing measures also exclude transactions 
       between all manufacturing industries.
