Friedrich August von Hayek (1899-1992) was an Austrian-British economist and political philosopher, a leading figure of the Austrian School of economics and a major theorist of classical liberalism in the twentieth century. He is best known for his work on the price mechanism as a means of coordinating decentralized knowledge, his critique of central economic planning, and his arguments connecting economic freedom to political liberty. He received the Nobel Memorial Prize in Economic Sciences in 1974, shared with Gunnar Myrdal.
Hayek's work spans economics, political philosophy, psychology, and the history of ideas. His major works include *Prices and Production* (1931), *The Road to Serfdom* (1944), *The Pure Theory of Capital* (1941), *The Constitution of Liberty* (1960), and the three-volume *Law, Legislation and Liberty* (1973-1979). His ideas are widely associated with arguments for limited government and free markets, though interpretations of the scope and limits of state action he endorsed are contested; see friedrich-hayek-viewpoint-debate for more.

Hayek's reputation and the reception of his ideas differ significantly between academic economics, political philosophy, and popular political discourse.
Within economics, Hayek's specific contributions to business cycle theory and capital theory-central to his early academic reputation-are not widely used in mainstream macroeconomics today, having lost prominence to Keynesian and later monetarist and New Classical frameworks. However, his work on the role of prices in transmitting decentralized information, articulated most influentially in his 1945 article “The Use of Knowledge in Society,” is widely cited across the political spectrum, including by economists who do not share his broader political views, and is frequently taught in price theory and information economics. His critique of central planning is regularly invoked in debates over comparative economic systems, though its applicability to specific present-day policy questions-such as industrial policy, healthcare systems, or regulatory design-remains contested.
In political philosophy, Hayek is read both as a theorist of spontaneous order and the rule of law and as a transitional figure between classical liberalism and twentieth-century libertarianism. Scholars dispute how to characterize his relationship to conservatism; Hayek himself addressed this directly in his essay “Why I Am Not a Conservative” (1960), arguing that his opposition to central planning and defense of individual liberty distinguished his thought from traditionalist conservatism, though he is nonetheless frequently cited by conservative and libertarian intellectuals and political movements.
Hayek's legacy is also a subject of recurring popular and political debate, particularly regarding his views on social insurance, monopoly, and the proper scope of government, and regarding his influence on later political figures and movements; see friedrich-hayek-controversy-legacy-controversy.
