Bill Black: Arnold Kling’s Cunning Hairdresser Theory of the Financial Crisis
Yves here. I have to confess that I love this title. It serves as a reminder that the meme that lenders in the crisis were somehow victimized by borrowers is a lame defense of rank incompetence or worse. The basic rule of lending is that all you have is downside from a credit perspective. The borrower is never going to perform better than the terms of the agreement, and he may well do worse. Any competent lender knows that borrowers can be overly optimistic, naive, unlucky, or downright crooked. Lenders therefore need to take prudent measures to protect themselves from these well-known borrower foibles, the most important being not lending to obvious bad risks, and adding enough margin to your cost of borrowing to cover debtor bad luck and your own miscalculation. So to have a huge explosion of borrower defaults, including a meaningful swathe of subprime borrowers defaulting in the first 90 days, is proof not of massive borrower chicanery, but massive lender incompetence or corruption (as in presuming they could dump the dodgy loan on the next fool in the securitization pipeline).
