Larry Summers on "House of Debt"

An interesting piece from Larry Summers in the Financial Times: Lawrence Summers on ‘House of Debt’ A short excerpt:

Atif Mian and Amir Sufi’s House of Debt, despite some tough competition, looks likely to be the most important economics book of 2014; it could be the most important book to come out of the 2008 financial crisis and subsequent Great Recession. Its arguments deserve careful attention, and its publication provides an opportunity to reconsider policy choices made in 2009 and 2010 regarding mortgage debt.
...
Mian and Sufi ... argue that, rather than failing banks, the key culprits in the financial crisis were overly indebted households. ... Mian and Sufi highlight how harsh leverage and debt can be – for example, when the price of a house purchased with a 10 per cent downpayment goes down by 10 per cent, all of the owner’s equity is lost. They demonstrate powerfully that spending fell much more in parts of the country where house prices fell fastest and where the most mortgage debt was attached to homes. So their story of the crisis blames excessive mortgage lending, which first inflated bubbles in the housing market and then left households with unmanageable debt burdens. These burdens in turn led to spending reductions and created an adverse economic and financial spiral that ultimately led financial institutions to the brink.
emphasis added

I have my copy of the book and will probably post a few comments soon too (thanks for nice mention of Calculated Risk on page 147).
