What the World Needs Now —More Hayek, Less Keynes. Quotable:
According to Nobel economist Fredrick Hayek, a contemporary of Keynes and perhaps his greatest critic, Keynes “was guided by one central idea . . . that general employment was always positively correlated with the aggregate demand for consumer goods.” Keynes argued that government should intervene in the economy to maintain aggregate demand and full employment, with the goal of smoothing out business cycles. During recessions, he asserted, government should borrow money and spend it.
Keynes’s thinking was a decisive departure from classical economics, because arbitrary “macro” constructs like aggregate demand had no basis in the microeconomic science of human action. As Hayek observed, “some of the most orthodox disciples of Keynes appear consistently to have thrown overboard all the traditional theory of price determination and of distribution, all that used to be the backbone of economic theory, and in consequence, in my opinion, to have ceased to understand any economics.”
