The havoc on Wall Street following the collapse of the subprime-mortgage market boils down to a simple truth: for years, lots of very smart people took lots of very foolish risks, betting borrowed billions on dubious mortgage derivatives, and eventually the odds caught up with them. But behind that simple truth is a more surprising one: the financial whizzes made bad decisions in part because that’s what they were paid to do.
Not literally, of course. The way that hedge-fund managers and investment-bank C.E.O.s get paid is supposed to make them perform better for the investors they serve. Hedge-fund managers, for instance, typically are paid “2 and 20”: they get two per cent of total assets as a management fee, and they keep twenty per cent of their investment gains (above some agreed-upon benchmark). Letting hedge-fund managers keep a chunk of their winnings gives them an incentive to do well for their clients: in theory, they get rich only if their clients do.
