Tyler Cowen notes Marcia Stigum's authoritative (aka 1000 pages) Money Market as a great source for understanding this crisis. I agree. It highlights that no one prior to this crisis, especially academics, had any clue it was coming, no theory that would have alerted them to coming problems.
In my 1983 edition of Money Markets there is nothing in the index under 'risk', let alone 'credit risk'. Updated versions have perfunctory mention, hardly enough to give one a clue about underwriting critera, loss curves, default rate transitions, recovery rates, the key criteria for consumer vs. commercial loans. Not relevant. Mainly a litany of definitions of various instruments, data on amounts outstanding, the minutia of daycount methodology for various securities. Its collection of facts is no more an insight into finance than a pile of bricks is a house.
My old KeyCorp boss, Kevin Blakely, told me a funny story about how he was asked, as a 45-year old banking executive with a history of risk management, to guest lecture in a Money & Banking class. He read up on the guy's notes, trying to see how he could work his insights into the class. It was all on fractional reserve banking and the money multiplier, the structure of the Federal Reserve, the Great Depression, inflation, etc., etc. In his words, nothing on actual banking, such as the many practicalities of credit risk.
Maybe soon.

In 2000, I took a graduate level class in Real Estate Finance at a top 25 business school, taught by one of the gurus in the field, who worked extensively with Deutsche Bank on MBS's. Default risk was only mentioned once in the class, in an annoyed response to a question - the answer was along the lines that default risk is both negligibly small and lies safely with Fannie, Freddie, and the mortgage insurers. The sole focus of the class was building structures that would load as much of the risk (mostly prepayment) in the H tranche, which was assumed to be held by the issuer. Bottomline: even then DEFAULT risk on a DEBT instrument was totally ignored, and at the graduate level too. I would ask for a refund, if I had not gotten a free ride for tuition.
