The "Cash for Clunkers" program was one of the most talked about sales promotions of recent memory. As part of the government's $3 billion effort to jumpstart sales at slumping auto dealerships, owners of old gas-guzzling vehicles received a $4,500 rebate if they traded in their "clunkers" for new fuel-efficient vehicles. Research the Cash for Clunkers sales promotion and have an in-class debate on what impact, if any, the stimulus program had on short- and long-term auto sales. The class should also debate the environmental benefits of the program.
