| News Story
|| The Bureau of Labor Statistics reported that its key
measure of inflation, the Consumer Price Index (CPI), has undergone
a major renovation for the first time in more than a decade. Major
changes to the CPI include:
- The addition of a major category, education and communication,
to the seven current categories. Communication, for example, will
cover consumer expenditures on cell phones.
- An improved statistical correction for quality changes, especially
in the area of personal computers.
- A revision in the relative importance of expenditure categories.
Changes include a relative decrease in consumer spending on food,
beverages, and transportation and an increase in housing and medical
These changes will be reflected first in the January 1998, CPI
The overhaul is part of a series of planned revisions that has
taken place over the past three years. The Council of Economic Advisers
estimates that these changes will trim the CPI by 0.7 percentage
points. Since the CPI is used to adjust Social Security and federal
pensions, as well as other federal programs including food stamps,
WIC, and the federal income tax system, a change of even 0.7 percent
can mean significantly lower federal government outlays. (Updated
