Three economists (from MIT and Tex A&M) have crunched the numbers and discovered that Obama’s Cash-for-Clunkers scheme back in 2009 was a failure even by Keynesian standards.

The 2009 Cash for Clunkers program aimed to stimulate consumer spending in the new automobile industry, which was experiencing disproportionate reductions in demand and employment during the Great Recession. Exploiting program eligibility criteria in a regression discontinuity design, we show nearly 60 percent of the subsidies went to households who would have purchased during the two-month program anyway; the rest accelerated sales by no more than eight months. Moreover, the program’s fuel efficiency restrictions shifted purchases toward vehicles that cost on average $5,000 less.
