During the current period when dealers have closed their showrooms, consumers are staying at home, and many have lost jobs and income, thoughts drift to how car sales can be encouraged again when it is once again safe to produce and sell new vehicles. A Cash for Clunkers repeat has come up as a natural option, although this time to drag the auto industry out of a crisis of a very different making.

So, What Was Cash for Clunkers?

For those who don't remember, it allowed consumers to trade in old vehicles for newer ones, promising a baseline incentive for nearly any worthless old car that could make it to a dealer lot and met certain fuel-economy criteria relative to then-new vehicles. One goal of the program was to spur trade-ins for new cars by giving buyers a voucher for a few thousand bucks (up to $4,500) no matter what pile they traded in; another was to get primarily older, less fuel-efficient vehicles off the road by tying the trade-in incentive to those aforementioned efficiency parameters. Adam Jonas, the outspoken auto analyst from Morgan Stanley, tellsBarron'sin an interview he does not think carmakers will fail or go bankrupt as a result of the current situation, but the industry will need support to get going again, restart factories, and jolt buyers back to showrooms—and the solution could once again be great deals supported by the government.

"We expect a Cash for Clunkers program to be much larger in scope and longer in duration than what we saw. In 2008 and 2009, we saw a $3 billion package that stimulated about $14 billion of purchases. This time around we're expecting about $10 billion of stimulus that drives $50 billion of purchases and adds about four million of SAAR [seasonally adjusted annualized rate, a measure of car purchases] over a six-month period beginning in the fall and then into early 2021," Jonas said.

There are some key differences in today's landscape. Jonas says politics plays a role: The original clunkers stimulus program in 2009 happened after the 2008 election, while this crisis occurs in the months leading up to one. And many of the key swing states in the 2020 presidential election are also key automaking states such as Michigan, Ohio, Indiana, Illinois, Texas, Kentucky, Mississippi, and Alabama.

Ramping up a new clunkers program this time has the advantage of using the 2008-2009 financial crisis as a precedent. We saw that it worked. We also have the logistics largely laid out.

The other big difference is that plants were still building cars and dealers were still selling them in 2008 and 2009, just in substantially fewer numbers. Conversely, the current pandemic forced plants and retail outlets to shut down temporarily so companies have no production to offset fixed costs, while stocks are slowly dwindling at dealers.
