Paul Krugman on Joseph Stieglitz:

But the larger story is the absence of a progressive-economist wing. A lot of people supported Obama over Clinton in the primaries because they thought Clinton would bring back the Rubin team; and what Obama has done is ... bring back the Rubin team.

Joe Stiglitz stands out because in addition to being on the progressive wing, he's also, as I said, a giant among academic economists. But I think the real story is more about excluded points of view than excluded people.
