Technical Note
Personal Income and Outlays
July 2009
Released: August 28, 2009
This technical note provides background information about the source data and
estimating methods used to produce the estimates presented in the personal income
and outlays news release. The complete set of estimates for July is available on BEA's
Web site at www.bea.gov; a brief summary of "highlights" is also posted on the Web site.
Personal income and outlays
In July, personal income increased less than 0.1 percent, disposable personal income
decreased less than 0.1 percent, and personal consumption expenditures (PCE)
increased 0.2 percent. After adjusting to remove price changes, real disposable income
decreased 0.1 percent and real PCE increased 0.2 percent.
Consumer Assistance to Recycle and Save Act of 2009
The federal CARS program (popularly called “cash for clunkers”), which began in July
2009 and ended on August 24, 2009, provides a credit of $3,500 or $4,500 for
customers who purchase a qualifying new, more fuel efficient auto or light truck from a
participating dealer when they trade in a qualifying less fuel efficient auto or light truck.
The credit is applied by the dealer to the customer’s purchase, after which the dealer is
reimbursed by the federal government. The impact of this program is reflected in PCE.
For sales to households, the discounted value of the sale is reflected in current-dollar
personal consumption expenditures (PCE). The effects of the discount and other price
changes are removed in the calculation of real PCE.
The sales of new motor vehicles under the CARS program are reflected in the source
data underlying BEA’s motor vehicles estimates; specifically, calculations of unit sales of
new autos and new light trucks by model from Ward’s Automotive Reports and of the
average vehicle price (after rebates and concessions) by model for new autos and for
new light trucks from J.D. Power and Associates.
The PCE and PFI motor vehicles estimates are deflated by detailed consumer price
indexes (CPIs) for new motor vehicles from the Bureau of Labor Statistics (BLS). The
detailed CPIs for new vehicles reflect “the average rebate, concession, and/or markup
during the preceding 30 days.” (See Chapter 17 of the BLS Handbook of Methods
(http://www.bls.gov/opub/hom/pdf/homch17.pdf), page 29.) Because most of the CARS
rebates for July occurred during the last week of the month, the July rebates will be
reflected in the CPIs for July and August—that is, the information on rebates enters the
indexes with a lag. BEA has made a small adjustment to the July price indexes for new
autos and for new light trucks to better align them with the timing of the CARS program
rebates/subsidies.
The following is a simplified example of how a transaction under the CARS program will
be reflected in PCE: Suppose a household purchases a new auto under the CARS
program and pays a negotiated price of $20,000 less a rebate of $3,500, for a
transaction price of $16,500. The purchase of the new auto will be included in PCE.

The valuation for current-dollar PCE is the net price paid by the household after the
rebate—which is $16,500, the value of the transaction for current-dollar PCE. (The
$3,500 will be reflected in the GDP statistics as a subsidy, which is like a negative sales
tax.)
For the calculation of real PCE, BEA deflates the current-dollar value by the relevant
price deflator, which in principle should reflect the decrease in the transaction price.
Thus, all else equal, the effects of the CARS program are reflected in increases in
quantity and decreases in prices for the motor vehicle component of PCE.
For further information on how the CARS program will be reflected in the GDP statistics,
please see the FAQ at BEA’s Web site, www.bea.gov, “How will the federal Consumer
Assistance to Recycle and Save Act of 2009 (i.e., the CARS program) be reflected in the
National Income and Product Accounts (NIPAs)?”
