Economics out of favour 1979–2007
Main article: Post-war displacement of Keynesianism
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. Its members included Austrian School economist Ludwig von Mises along with the then young Milton Friedman. Initially the society had little impact on the wider world – Hayek was to say it was as if Keynes had been raised to sainthood after his death and that people refused to allow his work to be questioned.[52][53] Friedman however began to emerge as a formidable critic of Keynesian economics from the mid-1950s, and especially after his 1963 publication of A Monetary History of the United States.
On the practical side of economic life, big government had appeared to be firmly entrenched in the 1950s but the balance began to shift towards private power in the 1960s. Keynes had written against the folly of allowing "decadent and selfish" speculators and financiers the kind of influence they had enjoyed after World War I. For two decades after World War II public opinion was strongly against private speculators, the disparaging label Gnomes of Zürich being typical of how they were described during this period. International speculation was severely restricted by the capital controls in place after Bretton Woods. Journalists Larry Elliott and Dan Atkinson say 1968 was a pivotal year when power shifted in the favour of private agents such as currency speculators. They pick out a key 1968 event as being when America suspended the conversion of the dollar into gold except on request of foreign governments, which they identify as when the Bretton Woods system first began to break down.

Criticisms of Keynes's ideas had begun to gain significant acceptance by the early 1970s as they were able to make a credible case that Keynesian models no longer reflected economic reality. Keynes himself had included few formulas and no explicit mathematical models in his General Theory. For commentators such as economist Hyman Minsky, Keynes's limited use of mathematics was partly the result of his scepticism about whether phenomena as inherently uncertain as economic activity could ever be adequately captured by mathematical models. Nevertheless, many models were developed by Keynesian economists, with a famous example being the Phillips curve which predicted an inverse relationship between unemployment and inflation. It implied that unemployment could be reduced by government stimulus with a calculable cost to inflation. In 1968 Milton Friedman published a paper arguing that the fixed relationship implied by the Philips curve did not exist.[55] Friedman suggested that sustained Keynesian policies could lead to both unemployment and inflation rising at once – a phenomenon that soon became known as stagflation. In the early 1970s stagflation appeared in both the US and Britain just as Friedman had predicted, with economic conditions deteriorating further after the 1973 oil crisis. Aided by the prestige gained from his successful forecast, Friedman led increasingly successful criticisms against the Keynesian consensus, convincing not only academics and politicians but also much of the general public with his radio and television broadcasts. The academic credibility of Keynesian economics was further undermined by additional criticism from other Monetarists trained in the Chicago school of economics, by the Lucas critique and by criticisms from Hayek's Austrian School.[37] So successful were these criticisms that by 1980 Robert Lucas was saying economists would often take offence if described as Keynesians.[56] Keynesian principles fared increasingly poorly on the practical side of economics – by 1979 they had been displaced by Monetarism as the primary influence on Anglo-American economic policy.[37] However many officials on both sides of the Atlantic retained a preference for Keynes, and in 1984 the Federal Reserve officially discarded monetarism, after which Keynesian principles made a partial comeback as an influence on policy making.[57] Not all academics accepted the criticism against Keynes – Minsky has argued that Keynesian economics had been debased by excessive mixing with neoclassical ideas from the 1950s, and that it was unfortunate the branch of economics had even continued to be called "Keynesian".[19]
Writing in The American Prospect Robert Kuttner argued it was not so much excessive Keynesian activism that caused the economic problems of the 1970s but the breakdown of the Bretton Woods system of capital controls, which allowed capital flight from regulated economies into unregulated economies in a fashion similar to Gresham's Law (where weak currencies undermine strong currencies).[58] Historian Peter Pugh has stated a key cause of the economic problems afflicting America in the 1970s was the refusal to raise taxes to finance the Vietnam War, which was against Keynesian advice.[59]
A more typical response was to accept some elements of the criticisms while refining Keynesian economic theories to defend them against arguments that would invalidate the whole Keynesian framework – the resulting body of work largely composing New Keynesian economics. In 1992 Alan Blinder was writing about a "Keynesian Restoration" as work based on Keynes's ideas had to some extent become fashionable once again in academia, though in the mainstream it was highly synthesised with Monetarism and other neoclassical thinking. In the world of policy making, free-market influences broadly sympathetic to Monetarism remained very strong at government level – in powerful normative institutions like the World Bank, IMF and US Treasury, and in prominent opinion-forming media such as the Financial Times and The Economist.[60]
