According to Calvin Trillin (or, more accurately, the probably-at-least-semi-fictional interlocutor he meets at a bar in Midtown), the financial crisis was caused by smart people going to work on Wall Street. In the old days, the story goes, it was the lower third of the class that went to Wall Street, and “by the standards that came later, they weren’t really greedy. They just wanted a nice house in Greenwich and maybe a sailboat. A lot of them were from families that had always been on Wall Street, so they were accustomed to nice houses in Greenwich. They didn’t feel the need to leverage the entire business so they could make the sort of money that easily supports the second oceangoing yacht.”
Then, however, as college debts and Wall Street pay grew in tandem, the smart kids started going to Wall Street to make the money, leading to derivatives and securitization, until finally: “When the smart guys started this business of securitizing things that didn’t even exist in the first place, who was running the firms they worked for? Our guys! The lower third of the class! Guys who didn’t have the foggiest notion of what a credit default swap was.”
Finance and the Housing Bubble
By James Kwak
Adam Levitin and Susan Wachter have written an excellent paper on the housing bubble with the somewhat immodest title, “Explaining the Housing Bubble” (which has been sitting in my inbox for a month). My main complaint with it is that it’s eighty-one pages long (single-spaced), which is most likely a function of law review traditions; had it been written for economics journals, it could have been one-third the length. I also have some quibbles with the seemingly obligatory paean to the importance of homeownership, which I think is an assumption that deserves to be contested. But overall it presents both a readable overview of the history and the issues, and a core argument I have a lot of sympathy for.
The argument is that the motive force behind the credit bubble was an oversupply of housing finance—in other words, the big, bad, banking industry. Levitin and Wachter’s key evidence is that the price of residential mortgage debt was falling in 2004-06 even as the volume of such debt was rising. As Brad DeLong’s parrot would say, that can only happen if the supply curve is shifting outward, not if the demand curve is shifting outward (which is what would happen if it were all the fault of greedy borrowers who wanted to flip houses).
