To produce prolonged recessions while assuming that companies are always forward looking and profit maximizing, the profession had turned to the so-called (New) Keynesian school, with its heavy reliance on various sorts of price “stickiness.” … But although price rigidities or stickiness can be used to explain short-term unemployment and recessions, they cannot explain longer-term downturns …

  1. Good points, but as a book it is repetitive.

    • I absolutely agree, Koo’s main argumentation could have been presented in 50-60 pages.

  2. Great Book, a must about the japan crisis and the 2008 crisis too !

    • Yes it’s great (actually the only thing I miss in it is an effort to relate to Minsky’s theory).
