Private nonfarm business sector: Real capital input by asset type, 1948-93 Historical, technical information: Media contact: USDL 95-48 (202) 606-5606 For Release: 10:00 AM EST (202) 606-5902 Tuesday, February 14, 1995 MULTIFACTOR PRODUCTIVITY TRENDS, 1993 Private Business and Private Nonfarm Business The Bureau of Labor Statistics (BLS) of the U.S. Department of Labor today reported multifactor productivity data--output per unit of combined labor and capital inputs--for 1993. BLS multifactor productivity uses chain-weighted output measures in place of constant 1987 dollar output used in the BLS labor productivity (output per hour) measures, which are published quarterly on a more current basis. (See summary of methods beginning on page 8.) Multifactor productivity changed at the following percentage rates in the most recent year available: 1992-93 Private business 0.6 Private nonfarm business 0.7 Multifactor productivity increased for the second consecutive year in 1993, but growth slowed to about half the rate of 1992. The 1993 annual changes are summarized in table A; further detail and historical measures are shown in tables 1 through 7. A change in multifactor productivity reflects the difference between the change in output (production of goods and services) and the change in labor and capital inputs engaged in the production of the output. Multifactor productivity does not measure the specific contributions of labor, capital, or any other factor of production. Instead, it reflects the joint effects of many factors, including new technology, economies of scale, managerial skill, and change in the organization of production. 2 Table A.

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. Changes in 1993 Private business sector Multifactor productivity in private business rose 0.6 percent in 1993. The 1993 gain was less than half the size of the 1992 gain (tables 1 and 3). While the 2.9 percent increase in output for 1993 was similar to the 1992 increase, combined units of capital and labor advanced at a 2.3 percent rate, more than twice the 1992 growth rate. Output in 1993 grew faster than in any year since 1988, but the gain was less than the average gain of the previous economic expansion (3.9 percent per year for the period 1982-90). Output is measured as a chained superlative index (Fisher Ideal). This output index is conceptually consistent with the alternative output indexes produced by the Bureau of Economic Analysis, U.S. Department of Commerce, rather than more traditional constant dollar output measures. 3 Capital services and especially labor input grew more rapidly in 1993 than in 1992. Labor input posted a 2.4 percent gain, more than twice the 1992 increase. Unlike 1992, an increase in employment (1.9 percent) accounted for most of the gain in labor input in 1993, while a slightly longer work week (0.3 percent) and an increase in the composition of labor (0.2 percent) accounted for the remainder. Capital services advanced 2.0 percent in 1993. Although capital services increased more rapidly than in 1992, the rate was slow viewed in historical terms. Among the types of capital investment (equipment, structures, inventories, residential rental housing, and land), the capital services of equipment posted the largest gain (tables 5 and 6). Labor productivity or output per hour worked advanced 0.7 percent in 1993, its slowest rate since 1989. Capital productivity (the ratio of output to capital services) increased 0.9 percent. Capital services per hour dropped 0.2 percent in 1993 after 4 years of increases. Private nonfarm business Multifactor productivity in private nonfarm business grew 0.7 percent in 1993 (tables 2 and 4). Output increased 3.3 percent, and combined units of capital and labor inputs rose 2.6 percent. The growth rate of labor input more than doubled to 2.7 percent. As with the private business sector, the increase in employment (2.1 percent) largely accounted for the growth in labor input. The remainder of the increase stemmed from a 0.4 percent rise in the work week and a 0.2 percent gain in labor composition. Capital services increased 2.1 percent in 1993. Capital services continued to grow slowly by historical standards. Most components of capital services also posted small gains (tables 5 and 7). The services of equipment accounted for most of the faster growth in capital services. In 1993, the 0.7 percent gain in labor productivity was the smallest since 1990. Capital productivity grew slightly faster than in 1992. Capital services per hour declined 0.4 percent, matching the previous drop in 1988. Long-term trends Labor productivity growth (output per hour) differs from multifactor productivity (output per unit of combined capital and labor inputs) in the treatment of capital and hours. Labor productivity measures do not explicitly account for the effects of capital or of shifts 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. However, multifactor productivity (MFP) treats capital as an explicit factor of production, and shifts in the composition of labor are included in the measures of labor input. Therefore, changes in capital intensity and labor composition do not affect measures of MFP. 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 the composition of the work force. 4 From 1948 to 1993, output per hour grew at an annual rate of 2.4 percent in private business and 2.1 percent in private nonfarm business (table B). Of the 2.4 percent growth rate in labor productivity in private business, 1.3 percent can be attributed to increases in multifactor productivity, 0.9 percent to the contribution of capital intensity, and 0.2 percent to changes in labor composition. The contribution of capital intensity equals the change in the capital-hours ratio multiplied by capital's share of total costs. 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 costs. Historically, capital's share has been less than one-third of total costs. The widely discussed post-1973 productivity slowdown is apparent from the data in table B. From 1948 to 1973, multifactor productivity grew at an annual rate of 2.2 percent in private business and 1.9 percent in private nonfarm business. These rates, combined with the growth rates in the contributions of capital intensity and labor composition, resulted in labor productivity growth rates of 3.4 percent and 2.9 percent, respectively, in private business and private nonfarm business. During the period 1973 to 1979, gains in multifactor productivity slowed to only 0.5 percent per year in private business. At the same time, the average annual contribution of capital intensity decreased to 0.7 percent, and the contribution of labor composition change was zero. Labor productivity, therefore, increased only 1.2 percent per year from 1973 to 1979. A similar slowdown occurred in private nonfarm business during the 1973-79 period. Between 1979 and 1990, multifactor productivity was almost unchanged in private business and private nonfarm business. Output per hour nevertheless continued to advance at the same rates as in the 1973-79 period. The contribution of labor composition increased to 0.3 percent per year in both sectors, essentially offsetting further declines in multifactor productivity growth. By post-1973 standards, labor productivity had relatively rapid gains of 1.5 percent per year during 1990-93 in both sectors. The increase in labor productivity in private business was the result of a 0.4 percent per year growth rate in multifactor productivity, a 0.6 percent contribution of capital intensity, and an unusually large 0.6 percent contribution of labor composition. Trends in private nonfarm business were virtually identical. However, productivity measures are strongly cyclical, and the 1990-93 period was dominated by the recovery from the 1990-91 recession. As a result, the data for this short period may not be indicative of new underlying trends and are not strictly comparable to trends in earlier periods. 5 Table B.

Source: Tables 1-2. 6 While MFP reflects many influences, it is generally believed that technological change is one of the primary contributors. For private nonfarm business, BLS has now estimated the direct effects of firms' spending on research and development (R&D) on MFP growth within their own industries. Because many people associate R&D spending and the resulting technology improvements with productivity, BLS has not adjusted MFP to exclude the effects of R&D. Instead, the estimated effects are shown separately (table B). The contribution of R&D averaged 0.2 percent per year for the entire 1948-93 period. Its contribution slowed to 0.1 percent per year during the 1973-79 period, but it has since returned to the 0.2 annual growth rate of the pre-1973 period. Summary of Methods This section 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, "Trends in Multifactor Productivity, 1948-81." The multifactor productivity indexes 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 1959-93, the output indexes are supplied by the Bureau of Economic Analysis (BEA) of the U.S. Department of Commerce. BLS adjusts these to eliminate the output of government enterprises. For the years 1948-58, BLS calculated output indexes by applying the Fisher index formula to data on categories of final expenditures in published tables from the National Income and Product Accounts (NIPA) produced by BEA. BLS linked these two indexes at 1959. Since 1983, BLS has used chained superlative indexes (Tornqvist indexes) to aggregate inputs. BLS has used several data sets to verify that Tornqvist and Fisher indexes yield results that are empirically quite similar. Capital input measures the services derived from the stock of physical assets. The assets included are fixed business equipment, structures, inventories, and land. Structures include nonresidential structures and residential capital which 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) weighting 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 and gross product originating by industry, used in measuring the rental prices, are obtained from BEA. 7 Labor input is obtained by (Tornqvist) weighting the hours worked by all persons, classified by education, work experience, and gender, 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, "Labor Composition and U.S. Productivity Growth, 1948-90." The labor and capital components of the input indexes are combined with (Tornqvist) weights which 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. The stock of Research and Development (R&D) in private nonfarm business is derived by cumulating constant dollar measures of R&D expenditures and allowing for depreciation. Current dollar expenditures for privately financed R&D for the years 1953-93 are obtained from annual issues of Research and Development in Industry published by the National Science Foundation. Price deflators and estimates of the rate of depreciation are developed by BLS. Further description of these data and methods can be found in BLS Bulletin 2331, "The Impact of Research and Development on Productivity Growth." Data are presented for the private business and private nonfarm business sectors. The private business sector, which accounts for about 80 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. The private nonfarm business sector also excludes farms, but includes agricultural services. These multifactor productivity measures describe the relationship between output in real terms and the labor time and capital services involved in its production. They do not measure the specific contributions of labor, capital, or any other factor of production. Rather, they reflect the joint effects of many factors, including new technology, economies of scale, managerial skill, and change in the organization of production. 8 Notes: BLS uses current dollar Gross Product Originating (GPO) data to estimate capital rental prices. Revised current dollar GPO data by industry, and its components by industry, are now available from BEA for the period 1959-92. For years prior to 1959, unrevised current dollar GPO data were used. GPO data for 1993 are not yet available. In the absence of 1993 GPO data, the BLS extrapolated capital asset cost shares so that relative rental prices were unchanged between 1992 and 1993. Value added measures of output for manufacturing are not available prior to 1977. Consequently, multifactor productivity measures for manufacturing using this output concept are unavailable. Measures of capital and labor inputs in manufacturing for the years 1948-93 are available upon request. In addition, manufacturing multifactor productivity, measured as gross output per combined units of capital, labor, energy, materials, and purchased business services, is available on request for the years 1948-91. Information in this release will be made available to sensory-impaired individuals upon request. Voice phone: 202-606-STAT; TDD phone: 202-606-5897; TDD message referral phone number: 1-800-326-2577.
