You've got to be kidding. Please explain how these "models" informed the ethics of what remains basically a shell game. What you mean to say is the "models" provided cover...rationalization for wild speculation and accounting tricks with other people's money, sans almost any equity.

"Models" have nothing to do with regulation, or with the lack of ethics that has brought us to this point, other than the curious coincidence that these "models" supported and aligned so well with unbridled greed.
