A Defense of the Paulson Plan
Academic economists don't like the Treasury plan, but nearly all of the Wall Street economists are for it. You don't have to be all that cynical to say that the Wall Street economists are talking their book. But I'd like to think that there is at least in part a sense in which they are more attuned to the reality of the situation in credit markets -- that last week we were a day or two away from a breakdown of the financial system.
Here are three common critiques from the academics and journalists and what they are missing:
1. "Treasury must overpay for this to work because otherwise you are not injecting new capital, only adding liquidity."
Treasury is talking with the experts you would expect -- prominent academics who have designed auctions. It's complex because there are so many different MBS, but Treasury is committed to get the market price as best as it can. It will not intentionally overpay. But the assertion that the plan will not boost capital is wrong. If Treasury gets the asset prices exactly right next week when the reverse auction starts, those prices will be higher than the prices that would have obtained before the program was announced. That difference means that by paying the correct price next week we will be injecting capital relative to the situation ex-ante. Treasury does not need to overpay. And the taxpayer can still see gains -- say if the announcement and enactment removes some uncertainty about the economy and asset performance, but not all. Then prices could rise further over time. But the main point is that it is not necessary to overpay to add capital. I think Krugman is a leading purveyor of the "they must be intending to overpay" assertion.
2. "Taxpayers will be better off if Treasury gets warrants."
This is essentially the assertion made in David Leonhart's column in the NY Times on Wednesday. And it again illustrates that we would all be better off if high schools taught the Modigliani-Miller theorem. MM implies that the price of the asset (again,assuming the auction gets it right) will adjust to offset the value of any warrants Treasury receives. In this case of a reverse auction, imagine that the price is set at $10. If Treasury instead demands a warrant for future gains of some sort, then the price will rise in the expected amount of the warrant -- say that's $2. Then the price Treasury pays for the asset will be $12. Some people might prefer to get $12 in cash and give up a warrant worth $2 in expected value. Fine, that's a choice to be made. But the assertion that somehow warrants are needed is simply wrong.
3."The plan should be to inject capital instead."
This is the Luigi Zingales criticism. Again, that's a fine plan and might be a good idea. But that's a complement to an asset purchase plan, not a substitute -- and it's one allowed by the Treasury proposal and indeed envisaged in some cases. But that will take much longer to implement than an asset purchase. That's why it's a complement not a substitute -- Treasury needs to act now. The particular ideas from Zingales et al that there should be a forcible capital injection are pure ivory tower, unfettered by the practicalities of legality, enactment, or implementation.
