1. Michael Shermer, The Moral Arc. I am only a few pages in, and he already has cited Bill Dickens and Bryan Caplan, among others.
2. Jeffrey Friedman and Wladimir Kraus, Engineering the Financial Crisis. This is a re-read for me. They share with me the view that risk-based capital rules contributed heavily to the crisis. They make a very subtle point, though. They do not believe that bankers went all-out to maximize the effective leverage of their banks. Thus, the authors reject the moral hazard arguments of deposit insurance and too-big-to-fail.
The way I would put their argument is this. Suppose that bank managers were, for whatever reason, actually quite concerned about risk exposure. They thought, even if incorrectly, that the value of keeping their franchises intact and avoiding trouble was very important. Even so, with the risk weights that regulators placed on different assets, the effective rate of return on mortgage securities was much higher than that on other asset classes, including low-risk mortgage loans. Thus, the risk-based capital rules, along with the lenient ratings by rating agencies of mortgage securities, served to steer capital into high-risk mortgage loans and thereby into feeding the housing bubble.
In making their argument that the crisis was in my terminology a cognitive failure rather than a moral failure, the authors point out that if bankers had merely wanted to maximize their exploitation of implicit and explicit guarantees, they could have acted differently. They could have held higher-risk, higher-return tranches of mortgage securities. They could have held less capital (before the crisis, major banks tended to have leverage ratios well below regulatory limits).
