Date: Monday, January 1 2001

IN DECEMBER 18, 2000, the Bureau of Economic Analysis (BEA) released the 1997 annual input-output (I-O) accounts for the U.S. economy. These accounts, which present estimates for 94 industries, are based on the 1992 benchmark I-O accounts and are prepared using 1997 estimates of industry and commodity

output and the 1997 estimates of gross domestic product (GDP) from last summer's annual revision of the national income and product accounts.1 The 1997 I-O accounts are the second annual update of the 1992 benchmark I-Oaccounts.2

Highlights from the release of these accounts include the following:

In terms of use, the fastest growing commodities in 1992-97 were among those that are frequently associated with high technology-- computers, electronics, and data-processing services.

The use of commodities that are often associated with outsourcing-data-processing services and other business and professional services-also grew rapidly in 1992-97.

The I-O accounts now include a new table that provides total requirements multipliers on an industry-by-industry basis; this information is useful for analyzing industry-to-- industry linkages.

The I-O accounts provide estimates of domestic production by commodity and industry, the export and import of commodities (goods and services), the use of commodities by each industry, the commodity composition of GDP (final demand), and the industry distribution of value added. The annual I-O accounts are used in a variety of analytical and statistical contexts, including studies of interindustry relationships within the economy and as the basis for developing satellite accounts on particular aspects of economic activity.

The 1997 annual I-O tables

The full 1997 annual I-O accounts are presented in eight tables.3 Two make tables, one that is based on I-O definitions of industry inputs (table 1) and an alternative that is based on the Standard Industrial Classification (SIC), show the commodities produced by each industry; two use tables, one on the I-O basis (table 2) and one on the SIC basis, show the commodities that are consumed by each industry.4 (Table A provides a summary version of the use table.)

Four requirements tables are derived from the make and use tables. The direct requirements table shows the amount of a commodity that is required by an industry to produce a dollar of that industry's output. The three total requirements tables show the production that is required, directly and indirectly, to meet purchases from final demand. The new table "Industry-by-Industry Total Requirements" (table 8) presents these total requirements with final-demand purchases classified by industry. This presentation is frequently used in I-O analysis when data on purchases are available only as purchases from industries rather than as purchases of commodities; it is also used to analyze industry-to-industry interdependencies or "linkages"-for example, the purchases of one industry's output by all other industries or the purchases of all other industries' output by one industry.

The presentation of the annual I-O tables is generally the same as that of the benchmark I-O tables, but the information is less detailed. The annual I-O tables present summary estimates for 94 industries, while the benchmark I-O tables present more detailed estimates for 498 industries.5 The annual use table presents 11 categories of final uses, while the benchmark use table presents 203 categories.6 The annual use and total direct requirements tables present estimates of total value added by industry, while the corresponding benchmark tables also decompose the total value into detailed estimates of value added for compensation of employees, indirect business tax and other nontax liability, and other value added.

Table C.-Commodity Consumption by Major Sector 1992, 1996, and 1997--Continued [Millions of dollars]

The estimates of commodity output and industry output in the make and use tables and the estimates of final uses in the use table are based on annual source data. Most of the other estimates are based on updated relationships from the 1992 benchmark I-O accounts.7

Uses of the I-O accounts

The I-O accounts are an important tool for economic analysis because they show the interdependence among producers and consumers in the U.S. economy. The accounts show the commodity composition of GDP (final demand), and the commodities used by the business sector to produce GDP (intermediate demand). Changes in the use of commodities provide information about changes in the structure of the economy and about the effect of these changes on production and economic growth. For example, a recent study of the contribution of computer and data-processing services to economic growth used I-O tables for 1972-96.8 Another study used the same set of tables to evaluate changes in the level of interindustry linkages and the effect of international trade on those linkages; the study shows that U.S. domestic industry interdependencies decreased over the period, partly as the result of declining manufacturing production and increased import penetration.9

Changes in the composition of total consumption, 1992-97

The series of I-O accounts can be used for comparisons of the structure of the U.S. economy over time. Changes in the use of commodities by the economy, both domestically and for export, are measured by changes in the composition of total consumption (table B).10 Comparisons over time of the consumption of commodities by sector provide indications of where structural changes are occurring (table C).

Over 1992-97, total commodity consumption grew at an average annual rate of 6.4 percent (table D). The consumption of services commodities (6.6 percent) grew faster than that of goods commodities (6.1 percent). Among the major commodity groups, the fastest rates of change were in "services" (7.3 percent) and finance, insurance and real estate (7.1 percent). Over the last year of the period, 1996-97, the fastest growth was in finance, insurance, and real estate (9.3 percent), transportation, communication, and utilities (8.8 percent), construction (8.8 percent), and "services" (8.2 percent).

The 15 commodities that accounted for at least 1 percent of total supply in 1997 and that grew faster than the overall commodity average in 1992-97 are shown in table E. These commodities included the following "high technology" commodities-computer and office equipment, electronic components and accessories, "communications, except radio and TV," and "computer and data-processing services, including own-account software" Consumption of these four commodities grew 12.0 percent, almost twice the rate of growth of all commodities, and the group's share of total consumption grew from 5 percent in 1992 to 6 percent, or $969.3 billion, in 1997.11

Among these commodities were at least two services that are often associated with "outsourcing"-other business and professional services and, again, "computer and data-processing services including own-account software." Consumption of these two commodities grew at an average annual rate of 11.6 percent in 1992-97 and 14.4 percent in 1996-97. These commodities accounted for 5 percent, or $841.2 billion, of total consumption in 1997, up from 4 percent in 1992.

These commodities also include finance, which grew at an average annual rate of growth of 10.4 percent over 1992-97 and accounted for 4.1 percent of total consumption in 1997. This commodity includes banking, credit agencies other than banking, and security and commodity brokers. Most of the above-average growth in finance was accounted for by rapid growth in the use of security and commodity brokers services-particularly securities commissions, underwriting fees, and other services.

IMAGE TABLE 40

Table E.-Commodities with Fastest Growing Consumption, 1992-97

For the six aforementioned commodities, the rapid growth in consumption can be traced to growth in demand by both intermediate and final users (table F). The growth in the consumption of electronic components and accessories and "other business and professional services, except medical" was due to growth in intermediate demand. Final users were primarily responsible for the increased consumption of computer and office equipment. Growth in the consumption of the other three commodities was the result of growth in demand from both sources.

Computer and office equipment.-Nearly 90 percent of computer and office equipment was consumed by the intermediate, gross private fixed investment (GPFI), and export sectors, and both the GPFI and export sectors grew at rates of at least 12 percent. In addition, personal consumption expenditures (PCE), which accounted for only 6.9 percent of total consumption, grew 16.2 percent.

Electronic components and accessories.-Nearly four-fifths of all electronic components and accessories flowed to intermediate uses, and virtually all of the remainder was exported. Intermediate use grew 13.9 percent, and exports grew 19.3 percent.

Communications, except radio and TV-Ninety percent of "communications, except radio and TV" was consumed by the intermediate and PCE sectors, and another 5.7 percent was consumed by the government sector. Consumption by all three sectors grew between 8 and 10 percent.

Computer and data-processing services, including own-account software.-Nearly 95 percent of "computer and data-processing services, including own-account software" was used by the intermediate, GPFI, and government sectors; the intermediate and GPFI sectors had a combined growth rate of more than 16 percent. In addition, PCE (primarily for prepackaged software), which accounted for only 2.8 percent of total consumption, grew 28.2 percent.

Other business and professional services, except.medicaL-Over four-fifths of "other business and professional services, except medical" was consumed in intermediate uses, and consumption by this sector grew 10.8 percent.

Finance.-The intermediate and PCE sectors accounted for more than 90 percent of total consumption, and these two sectors averaged over 10percent growth.

Methodology for the 1997 annual I-O accounts

The methodology used to prepare the 1997 annual I-O accounts is similar to that used for the 1996 annual I-O accounts. These accounts are based on the 1992 benchmark I-O accounts and on the most recently revised and updated estimates from the NIPA's. The annual estimates are based on less comprehensive and less detailed source data; for the annual estimates for which data were unavailable, the relationships from the 1992 benchmark accounts were extrapolated to 1997.

The annual I-O estimates are prepared in five steps: (1) The output total for each industry and commodity is calculated; (2) the commodity composition of intermediate inputs for each industry is estimated; (3) the domestic supply of each commodity is estimated; (4) the commodity compositions of the GDP expenditure components for PCE, gross private fixed investment, and government consumption and investment expenditures are derived; and (5) the table is balanced.12

An Ownership-Based Framework of the U.S. Current Account, 1982-98

IN THIS REPORT, the Bureau of Economic Analysis (BEA) updates its supplemental, ownership-based framework of the current-account portion of the U.S. international transactions (balance of payments) accounts.1 This presentation was developed in the first half of the 1990's in response to interest in a supplement to the existing international transactions presentation that would provide additional information about ownership.2 This interest arose from the increased interdependence of world economies that occurred as multinational companies (MNC's) have assumed a more prominent role in international markets by integrating production processes on a global scale and as commercial agreements have increasingly covered not only cross-border sales but also sales through locally established affiliates.

The globalization of economic activity can be viewed in a number of ways. From the perspective of MNC's, worldwide sales are aggregated irrespective of the location of the point of sale-for example, irrespective of whether the sale originated from the plant of a company in California or from a plant of that company in Ireland. In terms of the impact on the U.S. economy-- that is, from the traditional balance-of-payments perspective-the location of the seller is significant; moreover, for sales by affiliates, factor costs-such as labor and capital-and other costs must be subtracted from sales. Like the traditional international transactions accounts, the ownership-based framework presented in this report is organized by residency, but it broadens the definition of the balance on trade in goods and services to include net receipts of income by MNC's from the sales and purchases by their affiliates. The ownership-- based account is fully consistent conceptually with the current account of the traditional international transactions accounts and can be viewed as a "satellite" of those accounts.3

Highlights of this presentation for 1998 follow:

Worldwide sales by U.S. companies to foreign persons exceeded sales by foreign companies to U.S. residents by $363 billion. Sales by the U.S. companies to foreign persons were $3,173 billion; $933 billion were from cross-border sales (exports of goods and services), and $2,240 billion were sales by foreign affiliates. Sales by the foreign companies to U.S. residents were $2,810 billion; $1,100 billion were from cross-border sales (imports of goods and services), and $1,710 billion were sales by U.S. affiliates.

After deducting costs, such as those for labor, capital, and purchased goods and services, the income to U.S. companies from the sales by their foreign affiliates was $106 billion; this income combined with the value of U.S. goods and services exports yields a total value of trade accruing to the U.S. economy of $1,039 billion. After deducting costs, the income to foreign companies from the sales by their U.S. affiliates was $39 billion; this income combined with the value of US. goods and services imports yields a total value of U.S. trade accruing to foreign economies of $1,139 billion. The resulting balance of this ownership-based measure is -$99 billion, compared with the -$167 billion balance on trade of goods and services using the traditional balance-of-payments framework based on location of production.

The ownership-based estimates for 1982-97 have been revised to incorporate the results of last summer's annual revision of the U.S. international transactions accounts, and the estimates for 1997 have been revised to incorporate the latest financial and operating data of foreign-owned affiliates in the United States and of U.S.-owned affiliates abroad; new estimates are presented for 1998. Among the improvements that were incorporated last summer into the annual revision of the U.S. international transactions accounts were the following: Revised estimates of direct investment income receipts and payments for 1982 forward that reflect revised estimates of the current-cost adjustment, which incorporated revised estimates of prices for equipment and structures; revised estimates of "other private services" receipts for 1986 forward that reflect the use of improved estimates of international expenditures of international organizations in the United States and newly developed estimates of expenditures of temporary nonagricultural workers in the United States; and revised estimates of "other private services" receipts and payments for 1997 forward that reflect revisions to financial services receipts and payments.4

In the standard presentation of the current-account estimates, U.S. sales (exports) to foreigners (line 3 of table 1) consist only of the sales of goods and services that are delivered to foreign markets directly from the United States. In the ownership-based presentation, U.S. international "sales" (line 2) also includes the income that is received by U.S. companies from their affiliates abroad (line 8). Similarly, in the ownershipbased presentation, U.S. international "purchases" (line 22) includes the income that is paid by foreign-owned firms in the United States to their foreign owners as well as the payments for the goods and services that are directly delivered to the U.S. market from abroad. These additions, which raise the value of total U.S. "sales" and "purchases," provide a more comprehensive basis for assessing the effect of net "cross-border" sales on the U.S. economy.

In the table, the balance on goods, services, and net

SIDEBAR

receipts from sales by affiliates (line 43) shows the net result of the active participation of U.S. companies, including U.S. affiliates of foreign owners, in international markets. Each year, this balance has been in smaller deficit (or in surplus) than either the balance on goods and services or the balance on current account; in 1998, this balance was -$99.2 billion, compared with the balance on goods and services of -$166.9 billion. The balance was smaller because U.S. parents' receipts of income from their foreign affiliates has been greater than U.S. affiliates' payments of income to their foreign parents.

Additional information on ownership relationships is provided by the disaggregation of trade in goods and in services into trade between affiliated parties (that is, trade within MNC's) and trade between unaffiliated parties. Trade within MNC's is disaggregated into trade between U.S. parent companies and their foreign affiliates and trade between U.S. affiliates of foreign companies and their foreign parent groups. For receipts and payments of direct investment income, the table shows how the income is derived from the production and sales by affiliates.5 To highlight the links between the income and the activities that produce it, the income is designated "net receipts" or "net payments" of direct investment income resulting from sales by affiliates.

The addenda to table 1 provide supplemental information on the U.S. content and the foreign content of affiliates' output; this information can be used to describe affiliate operations and analyze the role of direct investment in supplying international markets. For both foreign and U.S. affiliates, output sold (or added to inventory) is broken down between U.S. content and foreign content; the source of the content is then broken down between the affiliates' own value added and other content.
