DeLong and Summers, the debate over potential output, and whether Bernanke has the courage, foresight, and persuasiveness to follow Greenspan's lead:
I wrote this before Bernanke's speech on the labor market on Monday. He says, echoing the topic of the column:
Is the current high level of long-term unemployment primarily the result of cyclical factors, such as insufficient aggregate demand, or of structural changes, such as a worsening mismatch between workers' skills and employers' requirements? ... I will argue today that ... the continued weakness in aggregate demand is likely the predominant factor.
So maybe the structural impediment, inflation hawk types at the Fed will be vanquished after all. We shall see. [See Tim Duy's comments on as well.]
