Specifically, Simon Johnson, former IMF chief economist, who notes that with Peter Orszag resigning as as director of the Office of Management and Budget (OMB), Paul Krugman would be the best replacement:

The president should nominate Paul Krugman to replace Peter Orszag as director of the Office of Management and Budget (OMB). (Orszag resignation details are here.)

………

But for the OMB position, the dynamic of a hearing would be terrific for the president’s specific agenda and broader messages. Krugman, of course, is the leading advocate for continued (or increased) fiscal stimulus. This is exactly President Obama’s message to the G20 this weekend.

Plus, when Republicans push back against Krugman on this issue, he will let them have it full blast on fiscal policy during the Bush administration. Krugman has, again and again, been an outspoken critic of the Bush era fiscal policy. He has precise chapter and verse on where the Bush team went off the deep fiscal edge.

………

It will not happen, of course, because Obama only tries to do the right thing when he has no other alternative, and there is simply not the pressure to have Krugman take the post.
