Economic Analysis of the Car Allowance Rebate System ("Cash for Clunkers")

U.S. Council of Economic Advisors
September 10, 2009

"The analysis contained here is necessarily speculative, because little can be said with confidence about two key questions: what is the time frame over which the 'payback' effect will occur, and what would the pace of clunker-replacement-induced demand for new cars have been in the absence of the program? The pace of motor vehicle sales and production in coming months will help narrow the range of plausible interpretations of the effects of the program, as will data from the Department of Transportation on the results of a survey of CARS participants who were asked about what their car-buying plans would have been. There may also have been important but harder to measure economic benefits of the CARS program that are not captured in our analysis, for example on consumer confidence. And of course, the program’s environmental benefits are not accounted for in our analysis.

We nevertheless believe that our analysis offers a reasonable starting point for assessing the program’s economic impact. At a minimum, it shows that if the sales payback is not immediate and complete, the program can be expected to have produced a noticeable impact on GDP growth."
