The second big event in Washington this week is the jostling over a financial reform bill. One might have thought that one of the lessons of this episode was that establishments are prone to groupthink, and that it would be smart to decentralize authority in order to head off future bubbles.

Both N. Gregory Mankiw of Harvard and Sebastian Mallaby of the Council on Foreign Relations have been promoting a way to do this: Force the big financial institutions to issue bonds that would be converted into equity when a regulator deems them to have insufficient capital. Thousands of traders would buy and sell these bonds as a way to measure and reinforce the stability of the firms.

But, alas, we are living in the great age of centralization. Some Democrats regard federal commissions with the same sort of awe and wonder that I feel while watching LeBron James and Alex Ovechkin.

The premise of the current financial regulatory reform is that the establishment missed the last bubble and, therefore, more power should be vested in the establishment to foresee and prevent the next one.

If you take this as your premise, the Democratic bill is fine and reasonable. It would force derivative trading out into the open. It would create a structure so the government could break down failing firms in an orderly manner. But the bill doesn’t solve the basic epistemic problem, which is that members of the establishment herd are always the last to know when something unexpected happens.

If this were a movie, everybody would learn the obvious lessons. The folks in the big investment banks would learn that it’s valuable to have an ethical culture, in which traders’ behavior is restricted by something other than the desire to find the next sucker. The folks in Washington would learn that centralized decision-making is often unimaginative decision-making, and that decentralized markets are often better at anticipating the future.

But, again, this is not a Hollywood movie. Those lessons are not being learned. I can’t wait for the sequel.
