So Many Narratives
Eric Falkenstein summarizes many books on the financial crisis, concluding
For me, the best explanation comes from two parts. Stan Liebowitz’s account on how we slowly eroded mortgage standards with the best intentions, led by academia, regulators, legislators, and investment banks. And then the accelerator mechanism outlined by Gary Gorton. Neither are books.
I agree that it is useful to think of what happened in the housing market and what happened among financial institutions. However, I think that Gorton’s “modern bank run” theory makes it seem as though the banks were fundamentally sound–just caught short of liquidity. I suspect that view is a bit self-serving on Gorton’s part (he helped get AIG into credit default swaps).
In the housing market, the positive feedback loop between increasing house prices and lower lending standards seems pretty important. It would be interesting to know whether other countries with housing bubbles also saw lower lending standards.
With financial institutions, I stress the use of regulatory capital arbitrage that allowed financial institutions to load up on risk. I think that their losses genuinely exceeded their capital. It was not just a liquidity panic.
Of course, the popular narrative is that it was greed coupled with the ideology of deregulation. My view is that regulators aided and abetted the crisis. They winked at lower lending standards because of the political popularity of broadening home ownership. They winked at regulatory capital arbitrage because they could not envision anything going terribly wrong.
