MULTIFACTOR PRODUCTIVITY TRENDS, 2003 AND 2004

Private Business and Private Nonfarm Business

The Bureau of Labor Statistics of the U.S. Department of Labor reported
today multifactor productivity data � output per combined units of labor 
and capital inputs � for 2003 and 2004.  The annual rates of multifactor 
productivity change from 2002 to 2003 and from 2003 to 2004 were:

					2002-03	2003-04
Private business sector	                  2.8	  2.9
Private nonfarm business sector	          2.7	  2.9


Multifactor productivity in the private business and private nonfarm
business sectors in 2003 and 2004 show the fastest rates of growth in 
the current time series, which go back to 1987.  In both sectors, 
multifactor productivity grew at a slightly faster pace in 2004 than in
2003.    The 2002-3 and 2003-4 annual changes are summarized in table A, 
and further detail and historical measures are shown in tables 1 through 6.
     
Multifactor productivity is designed to measure the joint influences of 
economic growth on technological change, efficiency improvements, returns
to scale, reallocation of resources, and other factors, allowing for the 
effects of capital and labor.  Multifactor productivity, therefore, 
differs from labor productivity (output per hour worked) measures that are
published quarterly by BLS since it includes information on capital 
services and other data that are not available on a quarterly basis.  
      
     
     
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 the output of government 
enterprises is omitted.
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.

     
 Chart 1 shows the annual indexes of multifactor productivity, output per
 hour worked, and output per unit of capital services for the 1987-2004 
 period for private business.  Over the last 17 years, capital services 
 have grown more rapidly than hours in the private business sector, and 
 the skills of workers -- as measured by their education and work 
 experience -- also have risen over this period.  These shifts toward more
 capital intensive production and toward workers with more human capital 
 have supplemented multifactor productivity growth, usually allowing output
 per hour to grow at a faster rate than multifactor productivity.


Private business sector

Changes in 2003.  Multifactor productivity rose 2.8 percent in 2003.  
Along with an almost similar increase in 2004, it was the largest rate of
increase in the current time series.  The multifactor productivity gain 
in 2003 reflected a 3.4 percent increase in output and a more modest 0.6 
percent increase in the combined inputs of capital and labor.
     
Growth in capital services slowed to 2.1 percent, the slowest growth since 
the current series began in 1987.  Labor input posted a slight drop of 0.1 
percent, marking the third consecutive year that labor input declined.  It 
had fallen 1.4 percent in 2001 and 1.3 percent in 2002.  Hours fell 0.5 
percent in 2003.  The capital-labor ratio (capital services per hour of 
all persons) increased by 2.7 percent.
    
Equipment capital services grew 3.5 percent in 2003, much more rapidly 
than other broad categories of capital assets (see table 5).  Within 
equipment, services of computers and related equipment grew 14.1 percent,
software 5.2 percent, communication equipment 4.9 percent, other 
information processing equipment 3.0 percent, and all other equipment 1.1 
percent.  However, these rates are markedly lower than in the 1995-2000 
period.  Services of structures and land continued to grow at rates 
similar to recent years, about one percent.  In the 1995-2000 period, 
services of structures were growing at a compound average annual rate of 
2.0 percent and services of land 0.7 percent.  Inventories grew at an 
annual rate of 0.8 percent in 2003, down from the 3.9 percent compound 
average annual rate of growth in the 1995-2000 period.

Labor input reflects the change in hours at work adjusted for the effects 
of changing labor composition.  As mentioned previously, labor input fell 
0.1 percent.  The modest decline of labor input was due to a decline in 
hours at work that was almost offset by a strong positive contribution 
from labor composition (see table A).  Hours fell 0.5 percent in 2003, 
the third consecutive year of decline.  Changes in labor composition, as
measured by shifts in the educational attainment and work experience of 
the work force, rose 0.4 percent  (see �Changes in the Composition of 
Labor for the BLS Multifactor Productivity Measures, 2004�, available at
http://www.bls.gov/web/mprlabor.pdf).  Employment declined 0.1 percent in 
2003.
     
Labor productivity (output per hour worked) increased 4.0 percent, nearly
the same as the growth rate of 4.1 percent in 2002.  Capital productivity
(output per unit of capital services) grew 1.3 percent, the first increase
since 1997.
     
Changes in 2004.  Multifactor productivity grew at an annual rate of 2.9 
percent, 0.1 percent more than in 2003.  The combined inputs of labor and
capital grew 1.8 percent, the fastest rise since the 2.6 percent increase
in 2000, and output rose at even a faster pace, 4.8 percent.

Capital services increased 2.5 percent in 2004.  Hours rose 1.3 
percent, ending three consecutive years of declines.  As a result, the
change in the capital-labor ratio, which is roughly equivalent to the 
growth in capital services less the increase in labor hours, grew 1.2 
percent.

Equipment continued to account for most of the growth in capital 
services, rising 4.0 percent, with information processing equipment and
software exhibiting the fastest growth rate among all equipment types, 
7.0 percent.  Services of structures grew at the same 0.9 percent rate 
as in 2003.  Growth rates for inventories and land almost doubled from 
the previous year.  Inventories grew 1.5 percent, higher than the 0.8 
percent increase in 2003.  Land rose 1.7 percent, up from 1.0 percent 
in 2003.

Labor productivity grew more slowly, 3.4 percent, than the 4.1 and 4.0 
percent increases in 2002 and 2003, respectively.  Labor input rose by 
1.5 percent after falling in the three previous years.  Most of the 
increase in labor input came from the 1.3 percent increase in hours; 
labor composition added an additional 0.2 percent.  Capital 
productivity grew 2.3 percent, the highest rate of growth in the 
current time series.
	 

Private nonfarm business

Changes in 2003.  Multifactor productivity in the private nonfarm business
sector rose 2.7 percent in 2003.  It was the largest rate of increase in 
the current time series.  Output increased 3.4 percent, and the combined 
inputs of capital and labor increased 0.7 percent.  
     
Labor input was unchanged.  Capital services grew 2.2 percent, the fourth 
consecutive year in which growth in capital services decelerated.  The 
fastest growing component of capital services was equipment (see table 6).
However, growth in equipment, 3.5 percent, was relatively slow compared to
the extremely high compound annual average rate of growth in 1995-2000 of
9.5 percent.  The increase in equipment in 2003 was largely due to capital
services of information processing equipment and software rising by 6.4 
percent.  As in previous years, the fastest growth in equipment was in 
computers and related equipment, which grew 14.1 percent.
     
Labor productivity grew 3.9 percent and capital productivity rose 1.2 
percent.  Capital services per hour increased at the rate of 2.6 percent.

Changes in 2004.	Multifactor productivity in the private nonfarm
business sector increased 2.9 percent, a 0.2 percentage point increase 
from the previous year.  Output grew 4.9 percent, an increase of 1.5 
percentage points from 2003, and the growth of combined capital and 
labor inputs rose 1.9 percent, an increase from 0.7 percent in 2003.

Labor input rose 1.6 percent in 2004, up from no growth in 2003.  Hours
at work contributed 1.4 of the 1.6 percent increase in labor input with
labor composition providing the additional 0.2 percentage point.  
Capital services grew 2.4 percent and, as a result, the capital-labor 
ratio rose only 1.0 percent, compared to 2.6 percent in 2003.

Labor productivity grew 3.4 percent, a drop from the 3.9 percent 
increase in 2003.  Capital productivity grew 2.4 percent, the second
consecutive annual increase.


Historical trends in private business and private nonfarm business

Labor productivity (output per hour worked) 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 nor do they account
for 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 experience of the work
force.  Therefore, multifactor productivity accounts for changes in labor
composition as well.  Historical trends in 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 (see table B).
     
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 a third of total payments.
Because trends in the private nonfarm business sector were similar to 
those in the private business sector in each period, the description that
follows focuses exclusively on the private business sector.
     
Over the 1987-2004 period, output per hour worked grew at an annual rate 
of 2.4 percent in private business (see table B).  Of the 2.4 percent 
growth rate in labor productivity, 1.1 percent can be attributed to 
increases in multifactor productivity, 0.9 percent to the contribution of
capital intensity, and 0.4 percent to changes in labor composition.  Since
1987, output per hour worked has accelerated, growing 1.5 percent in the 
1990-95 period, 2.7 percent in the 1995-2000 period, and 3.6 percent in 
the 2000-2004 period.
     
 In the period 1987-1990, all of the productivity measures (see table B) 
 grew to varying degrees.  Multifactor productivity increased at annual 
 average rate of 0.6 percent.  Labor productivity grew at annual average 
 rate of 1.5 percent.  The contribution of capital intensity averaged a 
 growth rate of 0.6 percent with information processing equipment 
 exhibiting a growth rate of 0.4 percent and other capital services 
 growing 0.1 percent.  The contribution of labor composition increased 
 0.4 percent.
     
Over the 1990-1995 period, increases in the productivity measures were 
similar to those in the 1987-1990 period.  Multifactor productivity rose
0.5 percent. Labor productivity grew at 1.5 percent, the same rate as in 
1987-1990.  The contribution of capital intensity grew 0.5 percent, with
information processing equipment contributing over 80 percent of this 
growth.  The contribution of labor composition rose 0.4 percent, the same
as in the previous period.
     
In the latter half of the 1990s, growth in productivity measures 
accelerated.  Multifactor productivity growth expanded 1.4 percent and
output per hour growth nearly doubled from the previous period, to 2.7
percent.  Growth of the contribution of capital intensity doubled from 
the previous period to 1.1 percent.  The growth of the two components of
the contribution of capital intensity, information processing equipment
and other capital services, also doubled from the previous period, with 
information processing equipment commanding an even more predominant 
share of the total contribution of capital services.  The growth of 
information processing equipment rose to 0.9 percent while other capital 
services grew 0.2 percent.  The contribution of labor composition dropped
0.1 percentage point from the previous period, to 0.3 percent.
     
In the 2000-2004 period, productivity measures continued to accelerate 
but at a slower pace.  Multifactor productivity growth increased an 
additional 0.5 percentage points from the previous period to 1.9 percent.
Labor productivity continued its upward trend, rising to 3.6 percent.  
The contribution of capital intensity growth gained 0.1 percentage points
from the previous period to 1.2 percent.  Growth in the composition of 
capital intensity came in equal parts from both of the major components.  
The contribution of information processing equipment dropped to a growth 
rate of 0.6 percent from 0.9 percent in the previous period.  At the same
time, other capital services rose to 0.6 percent.  The contribution of 
labor composition growth increased to 0.5 percent.

independent rounding.


Contribution of information processing equipment and all other capital may not 
sum to the contribution of capital intensity due to independent rounding.
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 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 1987-2004
period, or about 17 percent of total multifactor productivity growth 
(see table B).  The contribution of research and development varied little 
over time, contributing 0.2 percent per year during the following periods:
1987-90, 1990-95 period, and 1995-2000.  The contribution of research and 
development to multifactor productivity increased to 0.3 percent in recent
years, the 2000-04 period.


Revisions

Private business and private nonfarm business output series to 2004 
reflect the annual revisions to the National Income and Product Accounts
(NIPA), announced by the Bureau of Economic Analysis (BEA) in July 2005.
BLS built multifactor productivity measures from three-digit NAICS detail.
Most critical data were not reported on a NAICS basis for years prior to 
1998.  Detailed GDP by industry data, are available from 1998 forward, but 
from 1987-1997, many of the income components needed to construct capital 
rental prices were obtained by applying 1997 SIC-to-NAICS conversion 
factors to SIC data and adjusting to the resulting NAICS totals.  A      
similar procedure was applied to manufacturing inventories.  Detailed      
nonmanufacturing inventories were constructed using total inventory for      
the private business sector and nonmanfacturing industry shares of total      
inventory derived from the IRS book value of inventories reported for      
NAICS industries.  Land data were only available from 1998 to 2002 on a      
NAICS basis.  As a consequence, land estimates from 1987 to 1997 were      
calculated using a combination of SIC to NAICS conversion factors and more     
detailed IRS data.  Data for 2003 and 2004 were extrapolated using      
detailed IRS data for 2002.           
     
The Bureau of Labor Statistics has used Current Population Survey (CPS)       
data to measure the hours of nonfarm proprietors and unpaid family       
workers, and all persons working in the farm sector using the hours       
worked by people whose main job falls into these categories. Since the       
Productivity and Costs release of June 2005, hours for primary and       
secondary jobs held by persons working more than one job were processed      
separately and assigned to the appropriate class of worker for each job,      
rather than assigning all hours to the primary job.  Hours worked in a       
second job as a nonfarm employee by a proprietor (or other selected       
category of worker for whom our source is the CPS) were deducted to avoid      
double-counting.  Conversely, hours worked as a proprietor in a secondary      
job by a person who is primarily an employee were included. This       
multiple-jobholder adjustment yielded an improved measure of hours at       
work by sector and industry and the employment series approximated a       
count of jobs rather than persons. This adjustment has not yet been       
implemented within the manufacturing sector, where there are very few       
proprietors.       
Labor composition measures have been updated through 2004.  A brief      
description, �Changes in the Composition of Labor for the BLS Multifactor     
Productivity Measures, 2004� is available at

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.", the BLS      
Handbook of Methods, Chapter 10 at      
http://www.bls.gov/opub/hom/pdf/homch10.pdf, and on the BLS Multifactor     
Productivity website at http://www.bls.gov/mfp/mfpover.htm.   Additional

Capital Input:   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, terminals, tape drives, storage devices, and integrated
systems.  Software is comprised of pre-packaged, custom, and own-account
software.  Communications equipment is not further differentiated.  Other 
IPES includes medical equipment and related instruments, electromedical 
instruments, nonmedical instruments, photocopying and related equipment, 
and office and accounting machinery.  Structures include nonresidential 
structures and residential capital that is rented out by profit-making firms
or persons.
     
Financial assets are excluded from capital input measures, as are      
owner-occupied residential structures.  The aggregate capital input      
measures are obtained by Tornqvist aggregation of the capital stocks      
for each asset type within each of 60 NAICS industry groupings 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.  Data on inventories are obtained     
from BEA using additional information from IRS Corporation Income Returns.     
Estimates for land in the farm sector are obtained from USDA.  Nonfarm      
industry detail is based on IRS book value data.  Current-dollar gross      
product originating (GPO) data, obtained from BEA, are used in estimating     
capital rental prices.     
     
Labor Input:    Labor input in private business and private nonfarm      
business is obtained by Tornqvist aggregation of the hours at work by      
all persons, classified by education, work experience, and gender with      
weights determined by their shares of labor compensation.  Hours paid of     
employees are largely obtained from CES.  These hours of employees are      
then converted to an at-work basis by using information from the      
Employment Cost Index (ECI) of the National Compensation Survey and the     
Hours at Work Survey.  Hours at work for nonproduction and supervisory      
workers are derived using data from the CPS, the CES, and the NCS.  The      
hours at work of proprietors, unpaid family workers, and farm employees      
are derived from the Current Population Survey.  Hours at work data      
reflect Productivity and Costs data as of the February 2, 2006 news      
release.  It does not reflect benchmark revisions to the CES survey and     
other revisions to hours released on February 3, 2006.  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."     
    
Combined Inputs:  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 taxes on production and      
imports.  Most taxes on production and imports, 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.     
     
Output:  This release presents data for the private business and private     
nonfarm business sectors.  The private business sector, which accounted      
for approximately 77 percent of gross domestic product in 2000, 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 from the private business sector, but includes agricultural      
services.  Multifactor measures exclude government enterprises, while     
the BLS quarterly Productivity and Cost series include them.     
      
Multifactor Productivity:  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 of output,      
capital, and labor 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.     
      
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 1987 to 2004, BEA supplies the output indexes.       
BLS adjusts these to eliminate the output of government enterprises.     
     
      
 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 1987-2004      
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.
