Andrew Lo’s review of twenty-one financial crisis books has been getting a fair amount of attention, including a recent mention in The Economist. Simply reading twenty-one books about the financial crisis is a demonstration of stamina that exceeds mine. I should also say at this point that I have no arguments with Lo’s description of 13 Bankers.
Lo’s main point, which he makes near the end of his article, is that it is important to get the facts straight. Too often people accept and repeat other people’s assertions—especially when they are published in reputable sources, and especially especially when those assertions back up their preexisting beliefs. This is a sentiment with which I could not agree more. One of the things I was struck by when writing 13 Bankers was learning that nonfiction books are not routinely fact-checked (Simon and I hire and pay for fact-checkers ourselves). As technology and the Internet produce a vast increase in the amount of writing on any particular subject, the base of actual facts on which all that writing rests remains the same (or even diminishes, as newspapers cut back on their staffs of journalists).
I’m not entirely convinced by Lo’s example, however. He focuses on a 2004 rule change by the SEC. According to Lo, in 2008, Lee Pickard claimed that “a rule change by the SEC in 2004 allowed broker-dealers to greatly increase their leverage, contributing to the ﬁnancial crisis” (p. 33). That is Lo’s summary, not Pickard’s original. This claim was picked up by other outlets, notably The New York Times, and combined with the observation that investment bank leverage ratios increased from 2004 to 2007, leading to the belief that the SEC’s rule change was a crucial factor behind the fragility of the financial system and hence the crisis.
