Keynes's simplified starting point is this: assuming that an increase in the money supply leads to a proportional increase in income in money terms (which is the quantity theory of money), it follows that for as long as there is unemployment wages will remain constant, the economy will move to the right along the marginal cost curve (which is ...
Post-Keynesian economists, on the other hand, reject the neoclassical synthesis and, in general, neoclassical economics applied to the macroeconomy. Post-Keynesian economics is a heterodox school that holds that both neo-Keynesian economics and New Keynesian economics are incorrect, and a misinterpretation of Keynes's ideas. The post-Keynesian ...
Keynesian economics were officially discarded by the British Government in 1979, but forces had begun to gather against Keynes's ideas over 30 years earlier. Friedrich Hayek had formed the Mont Pelerin Society in 1947, with the explicit intention of nurturing intellectual currents to one day displace Keynesianism and other similar influences.
Prior to the financial crises of 2007-9, the majority new consensus view, still found in most current text-books and taught in all universities, was New Keynesian economics, which (in contrast to Keynes) accepts the neoclassical concept of long-run equilibrium but allows a role for aggregate demand in the short run. New Keynesian economists ...
Despite discarding Keynesian theory, new classical economists did share the Keynesian focus on explaining short-run fluctuations. New classicals replaced monetarists as the primary opponents to Keynesianism and changed the primary debate in macroeconomics from whether to look at short-run fluctuations to whether macroeconomic models should be ...
New Keynesian economists agree with New Classical economists that in the long run, the classical dichotomy holds: changes in the money supply are neutral. However, because prices are sticky in the New Keynesian model, an increase in the money supply (or equivalently, a decrease in the interest rate) does increase output and lower unemployment ...
Short run increases in demand can cause output to increase, putting upward pressure on prices. In the long run, this can cause demand to decrease; [14] or, if demand remains at a higher quantity of output, then the aggregate supply curve will also shift to a higher level of output and reach equilibrium at a higher quantity. Growth in long-run ...
