I worry whether the recent hearings with the CEOs of the major Wall Street banks, with their focus on blame and personality, will draw attention away from the more important issue: how we can best insure that money flows from savers to those investors who can produce the highest returns for society. Certainly bank reform is required. But we’ve got a huge problem with bad incentives, and they apply not just to banks, but to other corporations and even to households. These incentives make it possible for corporate managers to make big bucks while running losses, allow households to borrow beyond their means, and permit auto companies to pass highly leveraged auto loans to the government.
