Stiglitz on the PPIP

Obviously, he doesn't like it, and nicely explains why:

Consider an asset that has a 50-50 chance of being worth either zero or $200 in a year’s time. The average “value” of the asset is $100. Ignoring interest, this is what the asset would sell for in a competitive market. It is what the asset is “worth.” Under the plan by Treasury Secretary Timothy Geithner, the government would provide about 92 percent of the money to buy the asset but would stand to receive only 50 percent of any gains, and would absorb almost all of the losses. Some partnership!

Assume that one of the public-private partnerships the Treasury has promised to create is willing to pay $150 for the asset. That’s 50 percent more than its true value, and the bank is more than happy to sell. So the private partner puts up $12, and the government supplies the rest — $12 in “equity” plus $126 in the form of a guaranteed loan.

If, in a year’s time, it turns out that the true value of the asset is zero, the private partner loses the $12, and the government loses $138. If the true value is $200, the government and the private partner split the $74 that’s left over after paying back the $126 loan. In that rosy scenario, the private partner more than triples his $12 investment. But the taxpayer, having risked $138, gains a mere $37.

Even in an imperfect market, one shouldn’t confuse the value of an asset with the value of the upside option on that asset.

But Americans are likely to lose even more than these calculations suggest, because of an effect called adverse selection. The banks get to choose the loans and securities that they want to sell. They will want to sell the worst assets, and especially the assets that they think the market overestimates (and thus is willing to pay too much for).

But the market is likely to recognize this, which will drive down the price that it is willing to pay. Only the government’s picking up enough of the losses overcomes this “adverse selection” effect. With the government absorbing the losses, the market doesn’t care if the banks are “cheating” them by selling their lousiest assets, because the government bears the cost.

The main problem is not a lack of liquidity. If it were, then a far simpler program would work: just provide the funds without loan guarantees. The real issue is that the banks made bad loans in a bubble and were highly leveraged. They have lost their capital, and this capital has to be replaced.

Paying fair market values for the assets will not work. Only by overpaying for the assets will the banks be adequately recapitalized. But overpaying for the assets simply shifts the losses to the government. In other words, the Geithner plan works only if and when the taxpayer loses big time.
