More from Megan on the financial crisis:

Hindsight regulation:

"I hope that this will result in deep changes to our regulatory system, starting with unifying the diverse bank regulatory body, and giving them a stronger mandate to watch systemic risk like a hawk. I hope the GSEs will be broken up, stripped of their government guarantee, and regulated like other companies that do the same thing. I hope the central bank will pay more attention to inflation, and less to unemployment."
