                         MULTIFACTOR PRODUCTIVITY TRENDS 
                    FOR DETAILED MANUFACTURING INDUSTRIES, 2005

        The Bureau of Labor Statistics of the U.S. Department of Labor reported today on 
multifactor productivity � output per unit of combined inputs � for four-digit NAICS 
manufacturing industries through the year 2005.  Multifactor productivity rose in roughly 
two-thirds of the 86 detailed manufacturing industries in 2005, slightly fewer than in 
2004.  More industries experienced an increase in multifactor productivity over a longer 
period.  From 1987 to 2005, multifactor productivity increased in three-quarters of the 
manufacturing industries.  
        
	Multifactor productivity indexes relate the change in output to the change in the 
combination of labor, capital, and intermediate purchases consumed in producing that out-
put. Because industry multifactor productivity indexes explicitly account for inputs of 
capital and intermediates as well as labor, they are not influenced by the substitution of 
capital and intermediate inputs for labor, as are measures of labor productivity. Industry 
multifactor productivity indexes measure the joint influences on economic growth of a 
variety of factors, including technological change, returns to scale, enhancements in 
managerial and staff skills, changes in the organization of production, and other 
efficiency improvements.

        The attached tables present multifactor productivity and related series for all four-
digit manufacturing industries that are based, for the first time, on the North American 
Industry Classification System, or NAICS.  Historical data were reconstructed to reflect 
the switch to NAICS, and therefore these measures are not comparable with the detailed 
industry measures previously reported on a 1987 Standard Industrial Classification (SIC) 
basis. 
	 
2004-05 change

        Multifactor productivity rose in 58 industries in 2005, as output rose in 71 
industries and combined inputs rose in 55 industries.  Changes in multifactor productivity 
were broadly distributed and varied greatly across industries, even within 3-digit industry 
groups. (See Table 1 and Chart 1.)  Multifactor productivity rose by 3 percent or more in 
29 industries, but declined in 28 industries in 2005.
        
*Chart 1. Distribution of annual rates of change for multifactor productivity, 2004-2005 

        Five industries registered double-digit growth in multifactor productivity.  The 
largest increase in multifactor productivity, 27.6 percent, occurred in computer and 
peripheral equipment (NAICS 3341), followed by an increase of 18.9 percent in apparel 
knitting mills (NAICS 3151).  Output rose rapidly in the five industries with the largest 
productivity increases, while combined inputs declined in all five except computer and 
peripheral equipment.  The largest multifactor productivity decline was 10.9 percent in 
railroad rolling stock (NAICS 3365), where output increased but combined inputs rose 
much more rapidly.
        
*Chart 2. Number of industries with multifactor productivity growth, Annually, 2001-2005 
        
        The number of industries with multifactor productivity growth each year 
increased greatly after 2001. (See Chart 2.) While still high compared to 2001, the 58 
industries with multifactor productivity growth in 2005 represent a slight decline from the 
numbers that recorded growth in 2002, 2003, and 2004. Although output rose in 16 more 
industries in 2005 than in 2004, combined inputs increased in 19 more industries than in 
2004.  For most industries, input growth in 2005 was led by increases in intermediate 
purchases.  While capital services increased in 31 industries and labor hours rose in 30 
industries, intermediate purchases increased in 60 industries.

Long-term trends

        From 1987 to 2005, multifactor productivity rose in 65 industries. (See Table 2.)   
Output rose in 69 industries while combined inputs rose in 60 industries. Although more 
industries registered multifactor productivity growth from 1987 to 2005 than did so in 
2005, the average annual change in multifactor productivity was more modest for most 
industries over the long term.   Multifactor productivity grew between 0 percent and 3 
percent per year, on average, in 63 industries, and exceeded 3 percent per year in only 
four industries. (See Chart 3.)

*Chart 3. Distribution of annual rates of change for multifactor productivity, 1987-2005 

        The five manufacturing industries with the fastest growth in multifactor 
productivity over the period were all in the computer and electronic products subsector 
(NAICS 334).  The multifactor productivity growth of 17.5 percent per year in computer 
and peripheral equipment (NAICS 3341) and 14.9 percent in semiconductors and 
electronic components (NAICS 3344) were much faster than for any other manufacturing 
industry.

        Multifactor productivity declined in nineteen industries from 1987 to 2005.  
However, the average decline over the period was less than 1 percent per year for all but 
three industries. The largest decline in multifactor productivity was 1.8 percent per year 
in tobacco and tobacco products (NAICS 3122).

        Table 3 shows average annual multifactor productivity growth by industry 
between 1987 and 2005 and for various subperiods.  Multifactor productivity grew in 
more industries from 2000 to 2005 than in any of the other periods shown. (See Chart 4.)  
From 2000 to 2005, 68 industries recorded positive multifactor productivity growth, and 
12 industries recorded average annual growth in excess of three percent.  By comparison, 
from 1995 to 2000, 51 industries had positive multifactor productivity growth, with six 
industries growing at an average annual rate greater than three percent.  Average annual 
multifactor productivity growth accelerated in 55 industries in 2000 to 2005 compared to 
1995 to 2000.

Technical Note

Output

        Industry output is measured as sectoral output, the total value, in real terms, of 
goods and services produced for sale outside the industry. For most manufacturing 
industries, real output is measured by deflating nominal value of production, but for a few 
detailed industries within the petroleum refining, cement, iron and steel, and aluminum 
industries it is measured by physical quantities of output.  Industry value of production is 
derived by adjusting industry shipments for changes in inventories and subtracting intra-
industry transfers and resales.  Wherever possible, the indexes of industry output are 
calculated with a T�rnqvist 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 are constructed primarily 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. 

Combined Inputs 

	The index of combined inputs is a T�rnqvist index of separate quantity measures 
of labor, capital, and intermediate purchases inputs.  The growth rates of the various 
inputs are aggregated using their average relative cost shares in industry value of 
production as weights.  The labor weight is based on the total value of labor 
compensation, including fringe benefits.  The intermediate purchases weight is based on 
the total value of materials (adjusted to remove intra-industry transactions), fuels, 
electricity, and purchased services.  The capital weight is a residual calculated as the 
value of net production minus the value of labor compensation minus the value of 
intermediate purchases.

Capital Input

	The measure of capital input is based on the flow of services derived from the 
stock of physical assets. Physical capital is composed of 26 categories of equipment, 2 
categories of structures, 3 categories of inventories, and land. Capital services are 
estimated by calculating capital stocks; changes in the stocks are assumed to be 
proportional to changes in capital services for each asset.  

	Capital stocks are calculated using the perpetual inventory method, which takes 
into account the continual additions to and subtractions from the stock of capital as new 
investment and retirement of old capital occur.  The perpetual inventory method 
measures stocks at the end of a year equal to a weighted sum of all past investments, 
where the weights are the asset�s efficiency relative to a new asset. A hyperbolic age-
efficiency function is assumed to calculate the relative efficiency of an asset at different 
ages. 
        Estimates of investment by asset type are derived from annual capital 
expenditures by industry from the economic censuses and annual surveys of the Bureau 
of the Census, U.S. Department of Commerce, along with estimates of asset detail by 
industry from the capital flow tables of the Bureau of Economic Analysis.  

        Price changes are removed from the annual investment data before calculating 
stocks. Price deflators for each asset category are constructed by combining detailed price 
indexes (mostly PPIs) with weights from the BEA capital flow tables that reflect the 
industry�s use of individual asset commodities. 

        The index of aggregate capital input for each industry is an annually chained 
T�rnqvist quantity index.  To construct the index, the growth rates of the stocks of each 
type of asset are aggregated using weights that are the average of each asset type�s cost 
share in successive years.  The asset costs are estimated by multiplying the asset stocks 
by implicit rental prices.

Labor Input

        The industry labor input measures represent the hours of all workers in the 
industry. The primary source of data on employment and hours is the BLS Current 
Employment Statistics (CES) survey, which provides monthly data on the number of jobs 
held by wage and salary workers employed directly in nonfarm establishments. The CES 
survey also provides data on the average weekly hours of production and nonsupervisory 
workers in these establishments. 
        
        Data from the BLS Current Population Survey (CPS) are used to supplement the 
CES data. The Division of Industry Productivity Studies (DIPS) estimates the average 
weekly hours of nonproduction workers for each industry using data from the CPS 
together with the CES data. The hours of all workers are treated as homogeneous and are 
directly aggregated. 
        
Intermediate Purchases Input
        
        The measures of intermediate purchases input is constructed as a T�rnqvist aggregate 
of separate quantities of materials, services, fuels, and electricity consumed by each 
industry. Except for electricity, for which direct quantity data are available, quantities are 
derived by deflating current-dollar values with appropriate price deflators. 

        Nominal values of materials, fuels and electricity and quantities of electricity 
consumed by each industry are obtained from economic censuses and annual surveys of 
the Bureau of the Census, U.S. Department of Commerce.  Purchased business services 
are estimated using benchmark input-output tables and other annual industry data from 
the Bureau of Economic Analysis, U.S, Department of Commerce.  

        To avoid double counting, the materials estimates exclude the value of intra-industry 
purchases. Estimates of materials purchased from other establishments within the industry 
are subtracted from the gross measure of materials costs.

        Constant-dollar materials consumed are derived by dividing annual current-dollar 
industry purchases by a weighted price deflator for each industry. Materials deflators are 
constructed for each industry by combining detailed producer price indexes and import price 
indexes from BLS using weights based on detailed commodity data from the BEA 
benchmark input-output tables. Aggregate price indexes to deflate purchased business 
services are constructed in a similar manner.

        Annual total fuels consumed by each industry are also deflated with weighted 
price deflators.  Producer price indexes for individual fuel categories are weighted 
together with weights reflecting detailed fuels expenditures by industry from the Energy 
Information Administration, U.S. Department of Energy.
