Government Intervention in the Market for Toxic Cars:So how could the government fix the problem?
1. Government purchases of toxic cars
<...>
One danger in this plan is that if you overpay for the cars, e.g. give $7,500 when the breakeven price was, say, actually $5,000, then you have given the owner of the car lot $250,000 more than the cars were actually worth (this will be the loss to taxpayers). The dealer may need this money to stay solvent and stay in business, but, nevertheless, it is a windfall.
There are a lot of uncertainties here, and lots of ways to lose money. But it's possible to make money too.
2. Subsidies and Public-Private partnerships
<...>
And I should note that it doesn't have to be a subsidy. That's one way to do this - as a giveaway - but another way is through a no recourse loan (what is being called a partnership). Suppose that the government gives (up to) a $3,500 loan to a private sector buyer to purchase the car for $7,500. If it's a good car and the value rises above $7,500, say to $15,000, then government will get paid back (with interest) since the asset can be sold profitably (another option is for the government to demand a share of this profit through warrants or other means). But if it's a bad car, the price falls to zero and the loan is forgiven - it does not need to be repaid. So the private sector agents only have to put up a fraction of the price to control the asset, and their losses are limited to the amount they put up while the gains are potentially large.
This is, in essence, the Geithner Plan. If many of the loans are not repaid, or if the subsidy is too large, it could lose a lot of money, but it could also make money too.
3. Nationalization
Now for the Saab story. Another option is for the government to simply take over the car dealership. The dealership is essential to the economy of the town, without it people will struggle, and the government - for that reason - might consider temporarily taking over the dealership to prevent failure. In doing so, it would make an evaluation of the company's assets, pay off the people who loaned the business money up to this amount, which may require having them take a haircut, i.e. accept some percentage of what they are owed on the bad loans they made, and the owner would simply be wiped out (which is a benefit since the business is insolvent and this allows the owner to escape the loans that cannot be paid through liquidation).
After taking over, the government would stress test the cars it now owns, put the bad ones in the junk pile, and sell the rest back to the public. So long as it didn't pay the creditors too much when it took over, i.e. the haircut is sufficiently large, it ought to make money on the deal. But it could lose money here too.
The Point
But, and I want to stress this, the point of these plans is not to make money, the point is to keep the economy of the town going, to keep people employed. If people place a large value on security, then even if the government takes a loss on paper, it may not be an economic loss. That is, we must put a value on the jobs that are saved and the security it brings (simply imagine that the utility function has risk as one of its arguments - by lowering the risk of job loss and the associated household disruption, you have made the agent better off, and this must be counted against any loss from any of the programs above). There is value in economic stability and security over and above whatever the government makes (or loses) on the actual financial transactions, and this must be factored into the evaluation of the policy.
