"The Austrian School of Economics traditionally underestimates, if not neglects macroeconomics (or at least its importance), and Hayek understood that he was not going to win the debate accepting the Keynesian macro economic playground. He decided to attack the interventionist doctrine of Keynes by moving to microeconomics, to the defence of the irreplaceable role of markets and prices in the economy, and to demonstrating that interventionism makes the efficient functioning of markets impossible. His seminal articles “Economics and Knowledge,” and especially “The Use of Knowledge in Society,” are among the most important contributions to the field of economic science in the whole of the twentieth century. Hayek devoted his analysis to explaining the coordination of human action in a world in which knowledge is inevitably dispersed and he was able to prove that the solution is in the price system, not in central planning."
