The index for finished goods other than foods and energy declined 0.1 percent in December, following a 0.2-percent gain in November. Finished consumer foods prices decreased 0.1 percent in December, following a 0.8-percent decline a month earlier. Before seasonal adjustment, the Producer Price Index for Finished Goods decreased 0.9 percent to stand at 137.2 (1982=100). From December 2000 to December 2001, finished goods prices fell 1.8 percent -- the largest 12-month rate of decline since a 2.3-percent drop for the 12 months ended in December 1986. This index rose 3.6 percent during 2000. Prices for finished energy goods turned down 17.2 percent in 2001, following a 16.6-percent advance in the previous calendar year. For the 12 months ended in December 2001, the index for finished goods other than foods and energy rose 0.7 percent, after posting a 1.3-percent gain in 2000. Prices for finished consumer foods advanced at about the same rate in 2001 as in the prior calendar year -- 1.8 and 1.7 percent, respectively. At the earlier stages of processing, the intermediate goods index decreased 4.0 percent from December 2000 to December 2001, after registering a 4.1- percent rise during 2000. Prices received by producers of crude materials for further processing dropped 32.4 percent in 2001, following a 35.5- percent increase in the prior calendar year. (See summary below.)

This routine annual calculation may result in revisions to seasonally adjusted indexes for the previous 5 years. The following information will be available on February 13, 2002 (2 workdays prior to the release of PPI data for January 2002 on February 15): Seasonal factors for commodity indexes for the year 2002, Recalculated seasonal factors for the last 5 years (1997-2001) for the commodity indexes, Recalculated seasonal factors for the last 5 years (1997-2001) for the stage-of-processing indexes. In addition to recalculated seasonal factors, relative importances, as of December 2001, will also be available on February 13, 2002, at ftp://ftp.bls.gov which is the BLS ftp site. Choose the "pub" directory, the "special.requests" directory, and the "ppi" directory. To request any of this information, call the Division of Industrial Prices and Price Indexes, Section of Index Analysis and Public Information at (202) 691-7705. PPI Weights to be Updated The Bureau of Labor Statistics will soon update the value weights used to calculate Producer Price Indexes to more accurately reflect recent production and marketing patterns. The new weights, which will be introduced in February 2002 with the release of January 2002 index data, will be based on shipment values from the year 1997. These value weights come from the Census of Manufactures, the Census of Mining, the Census of Services, and the Census of Agriculture. PPI weights have been based upon 1992 census shipment values since January 1996. All indexes will be affected by this weight update, including all the industry net output indexes, as well as those calculated from traditional commodity groupings. In addition, weights will be updated from the 1992 to the 1997 census for all stage-of-processing indexes, net output of industry by stage of process indexes, durability of product indexes, and special commodity-grouping indexes. This weight revision will not change the arithmetic reference base, in most cases 1982=100, of the PPI index system. Also with the publication of January data on February 15, 2002, SIC- classified indexes will reflect updated input/output (I/O) ratios based on the 1992 Input-Output Account of the U.S. Department of Commerce's Bureau of Economic Analysis (BEA). These I/O ratios, which represent the proportion of each industry's output consumed outside the industry, will be updated from those reflected in BEA's 1987 Input-Output Account. The commodity grouping indexes will not be affected. It is important to note that the PPI classification system and aggregation structure will not change as a result of the weight revisions discussed above. The weight update, however, will result in significant shifts in the relative importance of various industries and products, and these shifts will impact future aggregate indexes in a manner commensurate with the relative gains and losses in value weights from 1992 to 1997. Relative importances as of December 2001 on the 1992 and 1997 weighting schemes will be available on February 13, 2002. To request this information call the Division of Industrial Prices and Price Indexes, Section of Index Analysis at (202) 691-7705. Table 1.

Technical Note Brief Explanation of Producer Price Indexes The term Producer Price Index (PPI) refers to a family of indexes that measure the average change over time in the selling prices received by domestic producers of goods and services. PPIs measure price change from the perspective of the seller. This contrasts with other measures, such as the Consumer Price Index (CPI); CPIs measure price change from the purchaser's perspective. Sellers' and purchasers' prices may differ due to government subsidies, sales and excise taxes, and distribution costs. More than 10,000 PPIs for individual products and groups of products are released each month. PPIs are available for the products of virtually every industry in the mining and manufacturing sectors of the U.S. economy. New PPIs are gradually being introduced for the products of industries in the transportation, utilities, trade, finance, and services sectors of the economy. More than 100,000 price quotations per month are organized into three sets of producer price indexes: (1) stage-of-processing indexes; (2) commodity indexes; and (3) indexes for the net output of industries and their products. The stage-of-processing structure (tables 1, 2, and 5) organizes products by class of buyer and degree of fabrication. The commodity structure (tables 2 and 3) organizes products by similarity of end-use or material composition. The entire output of various industries is sampled to derive price indexes for the net output of industries and their products (table 4). Within the stage-of-processing system, finished goods are commodities that will not undergo further processing and are ready for sale to the final demand user, either an individual consumer or business firm. Consumer foods include unprocessed foods such as eggs and fresh vegetables, as well as processed foods such as bakery products and meats. Other finished consumer goods include durable goods such as automobiles, household furniture, and appliances; and nondurable goods such as apparel and home heating oil. Capital equipment includes producer durable goods such as heavy motor trucks, tractors, and machine tools. The stage-of-processing category for intermediate materials, supplies, and components consists partly of commodities that have been processed but require further processing. Examples of such semifinished goods include flour, cotton yarn, steel mill products, and lumber. The intermediate goods category also encompasses nondurable physically complete items purchased by business firms as inputs for their operations. Examples include diesel fuel, belts and belting, paper boxes, and fertilizers. Crude materials for further processing are products entering the market for the first time that have not been manufactured or fabricated and that are not sold directly to consumers. Crude foodstuffs and feedstuffs include items such as grains and livestock. Examples of crude nonfood materials include raw cotton, crude petroleum, coal, hides and skins, and iron and steel scrap. Producer price indexes for the net output of industries and their products are grouped according to the Standard Industrial Classification (SIC). Industry price indexes are compatible with other economic time series organized by SIC codes, such as data on employment, wages, and productivity. Table 4 lists indexes for the net output of major mining and manufacturing industry groups at the 2-digit level. Producer price indexes are based on selling prices reported by establishments of all sizes selected by probability sampling, with the probability of selection proportionate to size. Individual items and transaction terms from these firms are also chosen by probability proportionate to size. BLS strongly encourages cooperating companies to supply actual transaction prices at the time of shipment to minimize the use of list prices. Prices are normally reported by mail questionnaire for the Tuesday of the week containing the 13th. Price data are provided on a voluntary and confidential basis; no one but sworn BLS employees are allowed access to individual company price reports. The Bureau publishes price indexes instead of unit dollar prices. All producer price indexes are routinely subject to revision once, 4 months after original publication, to reflect the availability of late reports and corrections by respondents. The BLS periodically updates the PPI sample of survey respondents to better reflect current conditions when the structure, membership, technology, or product mix of an industry shifts significantly and to spread reporting burden among smaller firms. Results of these resampling efforts are incorporated into the PPI every January and July. As part of an ongoing effort to expand coverage to sectors of the economy other than mining and manufacturing, an increasing number of service sector industries have been introduced into the PPI. The following list of recently introduced service industries includes the month in which an article describing the industry's content appeared in the PPI Detailed Report: PPI Detailed Industry SIC Report Issue Wireless Telecommunications 4812 July 1999 Telephone Communications, Except Radio Telephone 4813 July 1995 Grocery Stores 5411 July 2000 Meat and Fish (Seafood) Markets, 5421 July 2000 Fruit and Vegetable Markets 5431 July 2000 Candy, Nut, and Confectionery Stores 5441 July 2000 Retail Bakeries 5461 July 2000 Miscellaneous Food Stores 5499 July 2000 New Car Dealers 5511 July 2000 Miscellaneous Retail 59 January 2001 Security Brokers, Dealers, and Investment Bankers 6211 January 2001 Life Insurance Carriers 6311 January 1999 Property and Casualty Insurance 6331 July 1998 Operators and Lessors of Nonresidential Buildings 6512 January 1996 Real Estate Agents and Managers 6531 January 1996 Prepackaged Software 7372 January 1998 Home Health Care Services 8082 January 1997 Legal Services 8111 January 1997 Engineering, Design, Analysis, and Consulting Services 8711 January 1997 Architectural, Design, Analysis, and Consulting Services 8712 January 1997 Premiums for Property and Casualty Insurance 9331 July 1998 Weights for most traditional commodity groupings of the PPI, as well as all indexes (such as stage-of-processing indexes) calculated from traditional commodity groupings, currently reflect 1992 values of shipments as reported in the Census of Manufactures and other sources. From January 1992 through December 1995, PPI weights were derived from 1987 shipment values. Industry indexes shown in table 4 are also now calculated with 1992 net output weights. This periodic update of the value weights used to calculate the PPI is done to more accurately reflect changes in production and marketing patterns in the economy. Net output values of shipments are used as weights for industry indexes. Net output values refer to the value of shipments from establishments in one industry to establishments classified in another industry. However, weights for commodity price indexes are based on gross shipment values, including shipment values between establishments within the same industry. As a result, broad commodity grouping indexes such as the all commodities index are affected by the multiple counting of price change at successive stages of processing, which can lead to exaggerated or misleading signals about inflation. Stage-of-processing indexes partially correct this defect, but industry indexes consistently correct for this at all levels of aggregation. Therefore, industry and stage-of-processing indexes are more appropriate than broad commodity groupings for economic analysis of general price trends. Effective with publication of January 1988 data, many important PPI series (including stage-of-processing groupings and most commodity groups and individual items) were placed on a new reference base, 1982=100. From 1971 through 1987, the standard reference base for most PPI series was 1967=100. Except for rounding differences, the shift to the new reference base did not alter any changes to previously published percent changes for affected PPI series. (See "Calculating Index Changes," below.) The new reference base is not used for indexes with a base later than December 1981, nor for indexes for the net output of industries and their products. For further information on the underlying concepts and methodology of the Producer Price Index, see chapter 14, "Producer Prices," in BLS Handbook of Methods (April 1997), Bulletin 2490. Reprints are available from the Bureau of Labor Statistics on request. Calculating Index Changes Each index measures price changes from a reference period which equals 100.0 (1982 or some later month). An increase of 5.5 percent from the reference period in the Finished Goods Price Index, for example, is shown as 105.5. This change can also be expressed in dollars as follows: "Prices received by domestic producers of a systematic sample of finished goods have risen from $100 in 1982 to $105.50 today." Likewise, a current index of 90.0 would indicate that prices received by producers of finished goods today are 10 percent lower than they were in 1982. Movements of price indexes from one month to another are usually expressed as percent changes rather than as changes in index points because index point changes are affected by the level of the index in relation to its base period, whereas percent changes are not. The example below shows the computation of index point and percent changes. Index point change Finished Goods Price Index 107.5 Less previous index 104.0 Equals index point change 3.5 Index percent change Index point change 3.5 Divided by the previous index 104.0 Equals 0.034 Result multiplied by 100 0.034 x 100 Equals percent change 3.4 Seasonally Adjusted and Unadjusted Data Because price data are used for different purposes by different groups, the Bureau of Labor Statistics publishes seasonally adjusted and unadjusted changes each month. Seasonally adjusted data are preferred for analyzing general price trends in the economy because they eliminate the effect of changes that normally occur at about the same time and in about the same magnitude every year--such as price movements resulting from normal weather patterns, regular production and marketing cycles, model changeovers, seasonal discounts, and holidays. For these reasons, seasonally adjusted data more clearly reveal underlying cyclical trends. Unadjusted data are of primary interest to users who need information that can be related to actual dollar values of transactions. Individuals requiring this information include marketing specialists, purchasing agents, budget and cost analysts, contract specialists, and commodity traders. It is the unadjusted data that are generally cited in escalating long-term contracts such as purchasing agreements or real estate leases.
