New Keynesian Economics has been the most significant development in economics in recent years. However, many modern thinkers have asked whether it actually builds upon or merely distorts Keynes' work. This unique volume provides the first full-scale critique of the New Keynesian school of thought. Within its pages, Post-Keynesian economists, including many from the United States, challenge New Keynesianism both on the grounds that it is not Keynesian, and does not provide an adequate account of our current economic problems. Sure to provoke much new debate and even controversy, New Keynesian Economicsseeks to reconcile these two seemingly intractable systems.
