MULTIFACTOR PRODUCTIVITY TRENDS IN MANUFACTURING — 2007


Manufacturing sector multifactor productivity increased at a 4.7 percent
annual rate in 2007, the U.S. Bureau of Labor Statistics reported today 
(chart 1).  This was the largest gain in multifactor productivity in the
series which began in 1987 (table 1).  Multifactor productivity measures
the change in output per unit of combined inputs.  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, allowing for the effects of
capital, labor and, in the case of the manufacturing sector, intermediate 
inputs (energy, materials, purchased business services).  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.

Durable goods manufacturing sector multifactor productivity grew 6.0 percent
in 2007, accelerating from its 4.2 percent growth rate in 2006.  Nondurable
goods manufacturing sector multifactor productivity grew 3.0 percent in 2007, 
after a 0.6 percent increase in 2006.

Historical trends in manufacturing

Multifactor productivity in manufacturing grew 1.6 percent annually between
1987 (the starting point of the series) and 2007 (table A).  Sectoral output
increased at a 2.4 percent annual rate over the period and combined inputs 
rose an average of 0.8 percent per year.  Output per hour (labor productivity)
grew 3.6 percent.  For the 2000-2007 period, multifactor productivity in
manufacturing rose more rapidly than in previous periods, averaging 2.1 
percent per year, slightly outpacing the 2.0 percent growth rate in the 
1995-2000 period.  

Historical trends in growth in output per hour can be attributed to 
multifactor productivity growth and the contributions of the intensities 
of capital and of intermediate inputs.  The relationship between labor 
productivity growth and its components can be seen in table B and chart 2.  
Chart 2 shows how, relative to output per hour, contributions of multifactor 
productivity, capital intensity, and intermediate input intensity shifted 
upward in the latter half of the 1990’s.  These contributions have slowed 
somewhat during the 2000-2007 period.

Of the 3.6 percent growth rate in labor productivity in the 1987-2007 
period, 1.6 percent can be attributed to increases in multifactor 
productivity, 0.5 percent to the contribution of capital intensity, 0.7
percent to changes in materials intensity, and 0.7 percent to changes in
business services intensity (table B).  

The contribution of intermediate inputs includes energy, materials, and
purchased business services.  Multifactor productivity, the contribution 
of intermediate inputs, and the contribution of capital intensity may not
sum to output per hour due to independent rounding (chart 2). 

Revised Measures

Previous and revised productivity and related data for 2005 and 2006 for the 
manufacturing, durable goods manufacturing, and nondurable goods manufacturing
sectors are displayed in Table C.  In 2006, productivity growth was revised
upwards to 2.5 percent from 1.6 percent in the manufacturing sector, to 4.2 
percent from 3.2 percent in the durable manufacturing sector, and to 0.6 
percent from -0.2 percent in the nondurable manufacturing sector.  
Productivity growth was also revised downward for all three major sectors in 
2005.  The revisions in both years were due to large revisions in source data 
for energy, materials, and purchased services.

TECHNICAL NOTES

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.  									
The aggregate capital input measures are obtained by Tornqvist aggregation of 
the capital stocks for each asset type within each of the eighteen 
manufacturing 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 and software are
obtained from Bureau of Economic Analysis (BEA).  Nonfarm industry detail 
for land 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 Hours: Hours paid of production workers are obtained primarily from 
the Current Employment Statistics (CES) survey.  The hours of these employees
are then converted to an at-work basis by using information from the 
Employment Cost Index (ECI) of the National Compensation Survey (NCS) and the 
Hours at Work Survey.  Hours at work for nonproduction workers are derived 
using data from the Current Population Survey (CPS), the CES, and the NCS.  
The hours at work of proprietors are derived from the CPS.  The construction
of hours at work follows the methods used in the private business sector 
described in USDL 09-0480, Multifactor Productivity Trends, 2008, 
http://www.bls.gov/news.release/pdf/prod3.pdf , except that hours in 
manufacturing are directly aggregated and do not include the effects of 
changing labor composition.					
Hours at work data reflect Productivity and Costs data as of the 
March 5, 2009, news release.  Therefore it reflects the benchmark revisions
to the CES and other revisions to hours released on February 6, 2009.  
Data in this release do not reflect the comprehensive revision to the 
National Income and Product Accounts (NIPA) released by the Bureau of 
Economic Analysis of the U.S. Department of Commerce on July 31, 2009.  

Intermediate Inputs: In manufacturing, intermediate inputs are the largest 
input in terms of costs.  Furthermore, research has shown that substitution
among inputs, including intermediate inputs, affects productivity change. 
Therefore, it is important to include intermediate inputs 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 concepts and methodology,
productivity change in manufacturing cannot be directly compared with changes
in private business or private nonfarm business.  			
Intermediate inputs (energy, materials, and purchased business services) are 
obtained from BEA based on BEA annual input-output tables.  Tornqvist indexes
of each of these three input classes are derived at the 3-digit NAICS level
and then aggregated to total manufacturing.  Materials inputs are adjusted to
exclude transactions between establishments within the same sector.

Combined Inputs: 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.

Sectoral Output: The output concept used for multifactor productivity in 
manufacturing is “sectoral output.”  Sectoral output equals gross output 
(sales, receipts, and other operating income, plus commodity taxes plus 
changes in inventories), but excludes transactions between establishments
within the same sector. In contrast, the output concept used for private 
business and nonfarm business is “gross product originating” and is similar 
to “real value added”.  Gross product originating in private business equals
gross domestic product in the economy less general government, government 
enterprises, private households (including the rental value of owner-occupied
real estate), and non-profit institutions.  Gross product originating excludes
intermediate transactions between businesses.				

The output index for manufacturing is computed using a chained superlative 
index (Tornqvist) of three-digit NAICS industry outputs.   Industry output 
is measured as sectoral output, the total value of goods and services leaving
the industry. Wherever possible, the indexes of industry output are calculated
with a Tornqvist formula. This formula aggregates the growth rates of the
various industry outputs between two periods, using their relative shares in
industry value of production averaged over the two periods as weights.  
Industry output measures for manufacturing industries are constructed using
data from the economic censuses and annual surveys of the Bureau of the Census,
U.S. Department of Commerce, together with information on price changes, 
primarily from BLS. 

Productivity: The manufacturing multifactor productivity measures describe the 
relationship between output in real terms and the inputs involved in its 
production.  Manufacturing multifactor productivity measures exclude 
intermediate inputs between manufacturing establishments from both output
and inputs.  Multifactor productivity does 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.  The multifactor productivity indexes are 
derived by dividing an output index by an index of the combined inputs of 
labor, capital services, energy, non-energy materials, and business service
inputs.

Note: Multifactor productivity measures by industry do not sum up to aggregate 
      manufacturing measures because industry measures exclude transactions 
      only within the specific industry while the aggregate manufacturing 
      measures also exclude transactions between all manufacturing industries.
