Abstract
An Analysis of the Composition of Intermediate Inputs by Industry
by Erich H. Strassner and Brian C. Moyer
Presented at the 14th International Conference on Input-Output Techniques,
October 10-15, 2002, Montreal, Canada
The Gross Domestic Product (GDP) by industry accounts for the United
States provide industry estimates of value added, gross output, and intermediate
inputs based, in part, on data from the benchmark and annual input-output
(I-O) accounts for the United States. The GDP by industry data provide
a decomposition of an industry’s gross output into expenditures
on primary inputs--that is, value-added inputs--and expenditures on total
intermediate inputs. Recently, these data have been widely used in studies
of structural change and economic growth in the U.S. economy. This paper
extends the information available for such studies by introducing intermediate
inputs decomposed into the cost categories of energy, materials, and purchased
services using a time-series of I-O “use” tables. It develops
a conceptual framework for measuring intermediate-inputs price and quantity
growth and then uses this framework to prepare nominal estimates, chain-type
price indexes, and chain-type quantity indexes for intermediate inputs
by industry and by cost category. It also presents contributions by each
cost category to growth in the chain-type price and quantity indexes of
gross output. Data are consistent with the published GDP by industry accounts
and are presented for the years 1992- 2000.
