Quite a few excellent economists are worried about moral hazard in financial markets. Vince Reinhart wrote a Wall Street Journal column rebuking his former bosses after the Bear Stearns intervention: “…the Federal Reserve’s action can only be viewed as rewarding bad behavior.” Ken Rogoff recently wrote in a Financial Times column, “it is important to be tougher in busts, so that investors and company executives have cause to pay serious attention to risks. If poorly run financial institutions are not allowed to close their doors during recessions, when exactly are they going to be allowed to fail?”
