Goolsbee has been one of Obama's longest serving advisers. His ideas have been more or less progressive and even though he teaches at University of Chicago, he seems to come very much from a post Keynesian perspective.
It is rumored that he left out of frustration with the White House's stubborn resistance to move aggressively with policies to stimulate jobs and the economy.
|So runs the narrative among those inclined to accuse the administration of failing to marshal an adequate response to the strains of the Great Recession, setting aside plans to put Americans back to work via government-financed projects in favor of scrimping to shrink budget deficits.|
Goolsbee may not be the ideal guy from an MMT point of view to make policy, however, he was close enough than many of the others who currently advise Obama, so I consider it a terrible loss that he's now going.
