John Maynard Keynes offers a timely reconsideration of the work of the revered economics icon. Hyman Minsky argues that what most economists consider Keynesian economics is at odds with the major points of Keynes's The General Theory of Employment, Interest, and Money. Keynes and Minsky refuse to ignore pervasive uncertainty. Once uncertainty is given center stage, recurring episodes of financial system crises are all but inescapable. As Robert Barbera notes in a new preface, ?Benign economic circumstances?invite increasingly aggressive financial market wagers. Innovation in finance is a signature development in a capitalist economy. Once leveraged wagers are in place, small disappointments can have exaggerated consequences.? Thus for Minsky economic calm on Main Street engenders financial system fragility which, in turn, ensures a perpetuation of boom and bust cycles.
