What’s more bizarre? That Wall Street crashed from a very preventable problem (read Krugman today who is spot on) or that even after crashing, we’re showering them in even more money without even the slightest hitch. Are we nuts?

The costs of such a lopsided system of incentives are by now clear. Better regulation of mortgage markets would help avoid repeating current excesses. But more fundamental correctives are needed to curb financiers’ appetite for walking a tightrope. Some economists have suggested making their remuneration contingent on the performance of their investments over several years — releasing their compensation gradually.

That’s an idea worth studying. Certainly, trying to put specific limits on bankers’ salaries is a nonstarter. But until bankers face a real risk of losing their shirts, they will continue blithely ratcheting up the risks to collect the rewards while letting the rest of us carry the bag when their punts go bad.
