Very good Larry Summers FT review of Mian and Sufi

It is here, he mostly really likes the book but thinks they are not sophisticated enough in their policy prescriptions.  Here is one good excerpt on whether the federal government should have worked harder to institute mortgage cramdowns:

First, there was the risk of bringing down the system in an effort to save it. Banks had substantial mortgage holdings and especially large quantities of subordinated second mortgages and home equity lines of credit, which would have been wiped out if mortgage principal had been reduced in a way that respected the seniority of first mortgages. We recognised that large-scale principal reduction would draw in a large number of mortgages that were not delinquent and would otherwise be paid in full. As a consequence, there was the risk of sucking hundreds of billions of dollars out of the banking system. Given that government funds for capital infusions were scarce and that each dollar of bank capital supports $12 of lending, we worried that the spending gains from reducing mortgage debt might well be exceeded by the spending losses from reducing the flow of capital. This fear may have been exaggerated. If they think so, Mian and Sufi owe an explanation as to why.

Second, there was the issue of chilling future lending… This was not a small concern, as the automobile industry was in freefall and consumer confidence was deteriorating very rapidly.

Third, there was the danger of prolonging the housing market’s problems. Even the relatively limited programmes in place have spent as much as a third of their money delaying, rather than avoiding, foreclosures. All that we heard at the time suggested that a significant part of the reason why the housing market was dead was that no one wanted to buy because of a fear that it had further to fall. Delaying inevitable foreclosures with relief risked exacerbating this problem and risked larger foreclosure discounts when houses were ultimately sold.
