Friedrich Hayek's economics .

Herbert Simon* (Economics & Psychology, Stanford)

"No one has characterized market mechanisms better than Friedrich von Hayek". (Herbert Simon, The Sciences of the Artificial, 2nd Edition, Cambridge: The MIT Press, 1981, p. 41)

*Nobel Prize winner in Economics.

Lawrence Summers* (U.S. Treasury)

"What's the single most important thing to learn from an economics course today? What I tried to leave my students with is the view that the invisible hand is more powerful than the [un]hidden hand. Things will happen in well-organized efforts without direction, controls, plans. That's the consensus among economists. That's the Hayek legacy." (Lawrence Summers, quoted in The Commanding Heights: The Battle Between Government and the Marketplace that Is Remaking the Modern World, by Daniel Yergin and Joseph Stanislaw. New York: Simon & Schuster. 1998, pp. 150-151.)

*Lawrence Summers is President of Harvard U. & former Sec. of the U. S. Treasury & former Chief Economist of the World Bank.

Vernon Smith* (Economics, U. of Arizona)

"Hayek, in my view, is the leading economic thinker of the 20th century." (Vernon Smith, "Reflections on Human Action after 50 years", Cato Journal. Vol. 9, No. 2. Fall, 1999).

*Vernon Smith is the winner of the Nobel Prize in economics and the leading experimental economist in the U.S.

Fritz Machlup* (Economics, Princeton)

"One of the most original and most important ideas advanced by Hayek is the role of the 'division of knowledge' in economic society . . [But if] I had to single out the area in which Hayek's contributions were the most fundamental and pathbreaking, I would cast my vote for the theory of capital. As I said before, when I reviewed Hayek's book on The Pure Theory of Capital, it is 'my sincere conviction that this work contains some of the most penetrating thoughts on the subject that have ever been published.' If two achievements may be named, I would add Hayek's contributions to the the theory of economic planning. Most of what has been written on systems analysis, computerized data processing, simulation of market processes, and other techniques of decision-making without the aid of competitive markets, appears shallow and superficial in the light of Hayek's analysis of the 'division of knowledge', its dispersion among masses of people. Information in the minds of millions of people is not available to any central body or any group of decision-makers who have to determine prices, employment, production, and investment but do not have the signals provided by a competitive market mechanism. Most plans for economic reform in the socialist countries seem to be coming closer to the realization that increasing decentralization of decision-making is needed to solve the problems of rational economic planning." (Fritz Machlup, "Hayek's Contribution to Economics", Swedish Journal of Economics, Vol. 76, Dec. 1974.)

*Past President, American Economics Association.

Tom Peters*

"F. A. Hayek [is] arguably the most influential economist of this century."

*Leading American consultant and author on business management and strategy.

Friedrich Hayek's The Sensory Order.

Gerald Edelman* (Neurobiology, Scripps)

"I must say that I have been deeply gratified by reading a book [Hayek's The Sensory Order] of which I had not been aware when I wrote my little essay on group selection theory . . I was deeply impressed . . I recommend this book to your attention [i.e. The American Academy of Arts and Sciences], as an exercise in profound thinking by a man who simply considers knowledge for its own sake. What impressed me most is his understanding that the key to the problem of perception is to comprehend the nature of classification. Taxonomists have struggled with this problem many times, but I think von Hayek considered this problem in a broader sense." (Gerald Edelman, "Through a Computer Darkly: Group Selection and Higher Brain Function", Bulletin -- The American Academy of Arts and Sciences, Vol. XXXVI, No. 1, Oct. 1982, p. 24)

"[Hayek] made a quite fruitful suggestion, made contemporaneously by the psychologist Donald Hebb, that whatever kind of encounter the sensory system has with the world, a corresponding event between a particular cell in the brain and some other cell carrying the information from the outside word must result in reinforcement of the connection between those cells. These day, this is known as a Hebbian synapse, but von Hayek quite independently came upon the idea. I think the essence of his analysis still remains with us . . ". (Gerald Edelman, "Through a Computer Darkly: Group Selection and Higher Brain Function", Bulletin -- The American Academy of Arts and Sciences, Vol. XXXVI, No. 1, Oct. 1982, p. 25)

"My eventual aim [in Neural Darwinism] is to show the bearing of this [structural] diversity [of individual nervous systems] upon the problem of generalization and upon phenomena that point up the difference between the sensory and the physical orders (Hayek 1952)." (Gerald Edelman, Neural Darwinism, 1987, p. 33).

". . consider the two lines in the Wudt-Hering illusion . . This rather banal exercise serves to demonstrate that there is only a rough correspondence between what has been called the sensory order (Hayek 1952) and the physical order. Furthermore it bears upon point . . that the perceptual world is a world of adaptation rather than a world of complete veridicality." (Gerald Edelman, Neural Darwinism, 1987, p. 28).

*Nobel Prize winner in Physiology or Medicine, and Chairman of the Dept. of Neurobiology at the Scripps Research Institute.

Edwin Boring* (Psychology, Harvard)

"Half the time I read [Hayek's The Sensory Order] with amazement at the extent of his reading and comprehension . . he is right . . most of the time." (Edwin Boring, "Elementist Going Up", The Scientific Monthly, March, 1953, p. 183)

" . . I feel sure that no one has done this particular kind of job [i.e. a physicalistic system of psychology, mind, and consciousness] nearly so well." (Edwin Boring, "Elementist Going Up", The Scientific Monthly, March, 1953, p. 183)

"I do not for a moment believe it is the last word on this matter [i.e. a physicalistic system of psychology, mind and consciousness], but it is . the best word I have ever heard spoken from this platform." (Edwin Boring, "Elementist Going Up", The Scientific Monthly, March, 1953, p. 183)

*Boring is internationally known for his famous survey of psychology.

Joaquin Fuster* (UCLA School of Medicine)

"The first proponent of cortical memory networks on a major scale was neither a neuroscientist nor a computer scientist but .. a Viennes economist: Friedrich von Hayek (1899-1992). A man of exceptionally broad knowledge and profound insight into the operation of complex systems, Hayek applied such insight with remarkable success to economics (Nobel Prize, 1974), sociology, political science, jurisprudence, evolutionary theory, psychology, and brain science (Hayek, 1952)." (Joaquin Fuster, Memory in the Cerebral Cortex: An Empirical Approach to Neural Networks in the Human and Nonhuman Primate. Cambridge: MIT Press, 1995, p. 87)

*Fuster is a leading authority on the prefrontal cortext and the neuronal basis of memory.

The Hayek/Hebb Synaptic Model & Global Brain Theory.

Gerald Edelman* (Neuroscience, Scripps)

"[Hayek] made a quite fruitful suggestion, made contemporaneously by the psychologist Donald Hebb, that whatever kind of encounter the sensory system has with the world, a corresponding event between a particular cell in the brain and some other cell carrying the information from the outside word must result in reinforcement of the connection between those cells. These day, this is known as a Hebbian synapse, but von Hayek quite independently came upon the idea. I think the essence of his analysis still remains with us . . ". (Gerald Edelman, Neural Darwinism, 1987, p. 25).

"Most theoretical work since the proposals of Hebb (1949) and Hayek (1952) has relied upon particular forms of dependent synaptic rules in which either pre- or postsynaptic change is contingent upon closely occurring events in both neurons taking part in the synapse." (Gerald Edelman, Neural Darwinism, 1987, p. 181).

"Since [the idea that modification of synaptic function can provide a basis for memory arose shortly after the first anatomical description of the synapse] a number of models (Hebb 1949 . . Hayek 1952 . . Kendel 1981) have been proposed in which various cognitive activities are represented by combinations of the firing patterns of individual neurons." (Gerald Edelman, Neural Darwinism, 1987, p. 179).

"[Hebb] place the Law of Effect at the synaptic level by proposing a correlation model of synaptic modification similar to that of Hayek (1952). This work was seminal in providing a basis for many subsequent theoretical studies . . " (Gerald Edelman, Neural Darwinism, 1987, p. 12).

*Nobel Prize winner in Physiology or Medicine, and Chairman of the Dept. of Neurobiology at the Scripps Research Institute.

Joaquin Fuster* (UCLA School of Medicine)

"The main reasons for dwelling .. on Hayek's model is simply that it has certain properties, absent from most others, that conform exceptionally well to recent neurobiological evidence on memory and that make it particularly suited to the current discourse." (Joaquin Fuster, Memory in the Cerebral Cortex: An Empirical Approach to Neural Networks in the Human and Nonhuman Primate. Cambridge: MIT Press, 1995, p. 89)

"The first proponent of cortical memory networks on a major scale was neither a neuroscientist nor a computer scientist but .. a Viennes economist: Friedrich von Hayek (1899-1992). A man of exceptionally broad knowledge and profound insight into the operation of complex systems, Hayek applied such insight with remarkable success to economics (Nobel Prize, 1974), sociology, political science, jurisprudence, evolutionary theory, psychology, and brain science (Hayek, 1952)." (Joaquin Fuster, Memory in the Cerebral Cortex: An Empirical Approach to Neural Networks in the Human and Nonhuman Primate. Cambridge: MIT Press, 1995, p. 87)

"It is truly amazing that, with much less neuroscientific knowledge available, Hayek's model comes closer, in some respects, to being neurophysiologically verifiable than those models developed 50 to 60 years after his." (Joaquin Fuster, Memory in the Cerebral Cortex: An Empirical Approach to Neural Networks in the Human and Nonhuman Primate. Cambridge: MIT Press, 1995, p. 89)

"How is that apparatus formed? Here Hayek invokes a principle very similar to that of Hebb. In essence, it coincides with what we have called Hebb's second principle (sensorisensory association) transposed to the level of cell groups." (Joaquin Fuster, Memory in the Cerebral Cortex: An Empirical Approach to Neural Networks in the Human and Nonhuman Primate. Cambridge: MIT Press, 1995, p. 88)

"Friedrich Hayek .. seems to have been the first to postulate what is the core of this paper, namely, the idea of memory and perception represented in widely distributed networks of interconnected cortical cells. Subsequently this idea has received theoretical support, however tangential, from the fields of cognitive psychology, connectionism and artificial intelligence. Empirically, it is well supported by the physiological study and neuroimaging of working memory." (Joauin Fuster, "Network Memory", _Trends in Neuroscience_, 1997. Vol. 20, No. 10. (Oct .): 451-459.)

*Fuster is a leading authority on the prefrontal cortext and the neuronal basis of memory.

Hayek's work in philosophy.

Karl Popper* (Philosophy, L.S.E.)

"I think that I have learned more from you than from any other living thinker, except perhaps Alfred Tarski .. but not even excepting Russell." (letter from Karl Popper to Friedrich Hayek, 1944).

*Popper is regarded as among the most influential philosophers of science this century.

The character of Hayek's contribution to economics.

Jon Elster* (Columbia)

"The investigation of this problem -- How is spontaneous order possible? -- is sometimes referred to as the 'Hayek programme'. (Footnote 7 -- See notably Hayek (1978), vol. 1-3. For comments, see Gray (1986) and Vanberg (1986).) The present analysis differs in two ways from most other attempts to implement the programme. (Footnote 8 -- Attempt to implement the Hayek programme include those of Nozick (1974), Ullman-Margalit (1977), Schotter (1981), Hardin (1982), Axelrod (1984), Sugden (1986) and M. Taylor (1987).)" (John Elster, The Cement of Society: A Study of Social Order, 1989, p. 250)

*Elster is a recognized authority on the conceptual limitations of 'rational choice' theorizing.

Bruna Ingrao* (Economics, U. of Sassari) & Giorgio Israel* (Mathematics, U. of Rome)

"[Hayek's] equilibrium theory offered a wealth of suggestions that were to be taken up in the literature of the 1940s and 1950s. The ideas of intertemporal equilibrium, which was to be precisely defined in axiomatic terms by Arrow and Debreu, took shape in his writings of the 1920s and 1930s." (B. Ingrao & G. Israel, 1990, p. 233)

*Leading authorities on the history and limitatations of general equilibrium constructions.

Douglass North* (Economics, Washington U.)

"Information costs are reduced by the existence of large numbers of buyers and sellers. Under these conditions, prices embody the same information that would require large search costs by individual buyers and sellers in the absence of an organized market. (footnote 4: The original contributions were those of Hayek (1937 and 1945))." (Douglass North, Structure and Change in Economic History, New York: Norton, 1981, p. 36)

*Nobel Prize winner in Economics.

Brian Loasby* (Economics, Sterling)

"Many economists have professed to analyse information; relatively few have considered carefully the problems of knowledge. Among those who have, Hayek is pre-eminent." (Brian Loasby, The Mind and Method of the Economist, London: Edward Elgar, p. 38).

*Loasby is a respected authority on real-world business organization and decision making.

Fritz Machlup* (Economics, Princeton)

"One of the most original and most important ideas advanced by Hayek is the role of the 'division of knowledge' in economic society . . [But if] I had to single out the area in which Hayek's contributions were the most fundamental and pathbreaking, I would cast my vote for the theory of capital.

Friedrich Hayek & the Twentieth Century

Robert Skidelsky*

"[Hayek] became [in his later years] the dominant intellectual influence of the last quarter of the twentieth century".

*Skidelsky is the highly regarded biographer of John Maynard Keynes.

Peter Drucker*

"[Hayek's The Fatal Conceit] fully supports the recent characterization of Hayek by the Economist that he is our time's preeminent social philosopher."

*World-recognized analyst of business management practices and socio-economic institutions.

Julian Simon* (Economics, U. of Maryland)

"Friedrich Hayek, who died on March 23, 1992 at age 92, was arguably the greatest social scientist of the twentieth century. By the time of his death, his fundamental way of thought had supplanted the system of John Maynard Keynes -- his chief intellectual rival of the century -- in the battle since the 1930s for the minds of economists and the policies of governments." (Julian Simon, Hayek's Road Comes to an End, April 3, 1992)

*Well known authority on resource & population economics.

Douglass North* (Washington U., Economics)

"Regarding social order, [Francis] Fukuyama writes, "The systematic study of how order, and thus social capital, can emerge in spontaneous and decentralized fashion is one of the most important intellectual developments of the late twentieth century." He correctly attributes the modern origins of this argument to F. A. Hayek, whose pioneering contributions to cognitive science, the study of cultural evolution, and the dynamics of social change put him in the forefront of the most creative scholars of the 20th century."

*Nobel Prize Winner in Economics

Michael Lessnoff* (U. of Glasgow, Politics)

"Friedrich Hayek is the twentieth-century social theorist who, probably more than any other, found himself vindicated by events -- if not wholly, then at least in his central contention. He is also the one who, more than any other, himself exercised a significant political influence." (Michael Lessnoff, Political Philosophers of the Twentieth Century. New York: Blackwell. 1999. p. 146)

*Lessnoff is a specialist in the philosophy of social science & the political philosophy of the 20th century.

Kenneth Minogue* (U of London, Political Science)

"If the central contest of the twentieth century has pitted capitalism against socialism, then F. A. Hayek has been its central figure. He helped us to understand why capitalism won by a knockout. It was Hayek who elaborated the basic argument demonstrating that central planning was nothing else but an impoverishing fantasy." (Kenneth Minogue, "Giants Refreshed II: The Escape from Serfdom: Friedrich von Hayek and the Restoration of Liberty". TLS: Times Literary Supplement. Jan 14, 2000, p. 11)

*Minogue is a respected British political scientist.

Hayek and the International Triumph of the Liberal Order & Idea.

Milton Friedman* (Economics, U. of Chicago)

" . . I think the Adam Smith role was played in this cycle [i.e. the late twentieth century collapse of socialism in which the idea of free-markets succeeded first, and then special events catalyzed a complete change of socio-political policy in countries around the world] by Friedrich Hayek's The Road to Serfdom."

"Over the years, I have again and again asked fellow believers in a free society how they managed to escape the contagion of their collectivist intellectual environment. No name has been mentioned more often as the source of enlightenment and understanding than Friedrich Hayek's . . I, like the others, owe him a great debt . . his powerful mind . . his lucid and always principled exposition have helped to broaden and deepen my understanding of the meaning and the requisites of a free society."

*Nobel Prize winner in Economics.

Daniel Yergin* & Joseph Stanislaw*

".. Underlying all this has been a fundamental shift in ideas .. The dramatic redefinition of state and marketplace over the last two decades demonstrates anew the truth of Keynes' axiom about the overwhelming power of ideas. For concepts and notions that were decidedly outside the mainstream have now moved, with some rapidity, to center stage and are reshaping economies in every corner of the world. Even Keynes himself has been done in by his own dictum. During the bombing of London in World War II, he arranged for a transplanted Austrian economist, Friedrich von Hayek, to be temporarily housed in a college at Cambridge University. It was a generous gesture; after all, Keynes was the leading economist of his time, and Hayek, his rather obscure critic. In the postwar years, Keynes' theories of government management of the economy appeared unassailable. But a half century later, it is Keynes who has been toppled and Hayek, the fierce advocate of free markets, who is preeminent ..". (Daniel Yergin & Joseph Stanislaw, The Commanding Heights: The Battle Between Government and the Marketplace that Is Remaking the Modern World. New York: Simon & Schuster. 1998. pp. 14-15)

* President & Managing Director of Cambridge Energy Research Associates.

Irving Kristol* (editor, The Public Interest)

".. the most intelligent defender of capitalism [in the modern period has been Friedrich Hayek] .. Hayek .. has as fine and as powerful a mind as is to be found anywhere."

"It is in good part because of Professor Hayek's work [on 'social engineering' and 'scientism'], and also because of his profound insights -- most notably in The Constitution of Liberty -- into the connection between a free market, the rule of law, and individual liberty, that you don't hear professors saying today, as they used so glibly to say, that 'we are all socialists now'."

"As a result of the efforts of Hayek .. and the many others who share [his] general outlook, the idea of a centrally planned and centrally administered economy, so popular in the 1930s and early 1940s, has been discredited."

*Kristol is well-known as the intellectual leader of the 'neo-conservatives' in America.

Thomas Sowell* (Hoover Institute)

"The 20th Century looked for many decades as if it were going to be the century of collectivism .. Anyone who would have predicted the reversal of this trend .. would have been considered mad just a dozen years ago. Innumerable factors led to [the reversal of the rise of collectivism], not the least of which was the bitter experience of seeing 'rational planning' degenerate into economic chaos and Utopian dreams turn into police-state nightmares. Still, it takes a vision to beat a vision .. An alternative vision had to become viable before the reversal of the collectivist tide could begin with Margaret Thatcher in Britain and Ronald Reagan in the United States. That vision came from many sources, but if one point in time could mark the beginning of the intellectual turning of the tide which made later political changes possible, it was the publication of The Road to Serfdom by Friedrich A. Hayek ..".

*Sowell is a leading historian of economic thought, and an internationally recognized authority on the problems of race, politics, and culture.

Margaret Thatcher (British Prime Minister, 1979-1990)

".. the most powerful critique of socialist planning and the socialist state which I read at this time [the late 1940's], and to which I have returned so often since [is] F. A. Hayek's The Road to Serfdom." (Margaret Thatcher, The Path to Power, New York: Harper Collins, 1995, p. 50).

"Our inspiration was less Rab Butler's Industrial Charter than books like Colm Brogan's anti-socialist satire, Our New Masters . . and Hayek's powerful Road to Serfdom, dedicated to 'the socialists of all parties'. Such books not only provided crisp, clear analytical arguments against socialism, demonstrating how its economic theories were connected to the then depressing shortages of our daily lives; but by their wonderful mockery of socialist follies, they also gave us the feeling that the other side simply could not win in the end. That is a vital feeling in politics; it eradicates past defeats and builds future victories. It left a permanent mark on my own political character, making me a long-term optimist for free enterprise and liberty ..". (Margaret Thatcher, The Downing Street Years, New York: Harper Collins, 1993, pp. 12-13.)

John Ranelagh writes of Margaret Thatcher's remark at a key Conservative Party meeting in the late 1970's, "Another colleague had also prepared a paper arguing that the middle way was the pragmatic path for the Conservative party to take .. Before he had finished speaking to his paper, the new Party Leader [Margaret Thatcher] reached into her briefcase and took out a book. It was Friedrich von Hayek's The Constitution of Liberty. Interrupting [the speaker], she held the book up for all of us to see. 'This', she said sternly, 'is what we believe', and banged Hayek down on the table." (John Ranelagh, Thatcher's People: An Insider's Account of the Politics, the Power, and the Personalities. London: HarperCollins, 1991.)

"For Dicey, writing in 1885, and for me reading him some seventy years later, the rule of law still had a very English, or at least Anglo-Saxon, feel to it. It was later, through Hayek's masterpieces The Constitution of Liberty and Law, Legislation and Liberty that I really came to think this principle as having wider application." (Margaret Thatcher, The Path to Power, New York: Harper Collins, 1995, pp. 84-85.)

".. all the general propositions favouring freedom I had .. imbibed at my father's knee or acquired by candle-end reading of Burke and Hayek ..". (Margaret Thatcher, The Path to Power, New York: Harper Collins, 1995, p. 604).

".. Adam Smith, the greatest exponent of free enterprise economics till Hayek and Friedman." (Margaret Thatcher, The Downing Street Years, New York: Harper Collins, 1993, p. 618)

Ronald Reagan (U.S President, 1981-1989)

"Rowland Evans: "What philosophical thinkers or writers most influenced your conduct as a leader, as a person?" Ronald Reagan: "Well .. I've always been a voracious reader -- I have read the economic views of von Mises and Hayek, and .. Bastiat .. I know about Cobden and Bright in England -- and the elimination of the corn laws and so forth, the great burst of economy or prosperity for England that followed." (Rowland Evans & Robert Novak, The Reagan Revolution, New York: E. P. Dutton, 1981, p. 229).

"The most important player on Ronald Reagan's economic team is Ronald Reagan. The person most responsible for creating the economic program that came to be known as Reaganomics is Reagan himself. For over twenty years he observed the American economy, read and studied the writings of some of the best economists in the world, including the giants of the free market economy -- Ludwig von Mises, Friedrich Hayek and Milton Friedman -- and he spoke and wrote on the economy, going through the rigorous mental discipline of explaining his thoughts to others. Over the years he made all the key decisions on the economic strategies he finally embraced. He always felt comfortable with his knowledge of the field and he was in command all the way." (Martin Anderson, Revolution, New York: Harcourt Brace Jovanovich, 1988, p. 164.)

George Bush (U.S. President, 1989-1993)

"[Hayek is] one of the great thinkers of our age .. [he] revolutionized the world's intellectual and political life." (Presidential statement, 1991).

Milton Friedman* (Economics, U. of Chicago)

" .. My interest in public policy and political philosophy was rather casual before I joined the faculty of the University of Chicago. Informal discussions with colleagues and friends stimulated a greater interest, which was reinforced by Friedrich Hayek's powerful book The Road to Serfdom, by my attendance at the first meeting of the Mont Pelerin Society in 1947, and by discussions with Hayek after he joined the university faculty in 1950. In addition, Hayek attracted an exceptionally able group of students who were dedicated to a libertarian ideology. They started a student publication, The New Individualist Review, which was the outstanding libertarian journal of opinion for some years. I served as an adviser to the journal and published a number of articles in it .. ". (Milton & Rose Friedman, Two Lucky People: Memoirs, Chicago: U. of Chicago Press, 1998. p. 333).

*Nobel Prize winner in economics.

Hayek and the Revolution in Europe.

Andrzej Walicki* (History, Notre Dame)

"The most interesting among the courageous dissenters of the 1980s were the classical liberals, disciples of F. A. Hayek, from whom they had learned about the crucial importance of economic freedom and about the often-ignored conceptual difference between liberalism and democracy." (Andrzy Walicki, "Liberalism in Poland", Critical Review, Winter, 1988, p. 9.)

*Walicki is formerly of the Institute of Philosophy and Sociology at the Polish Academy of Sciences.

Mart Laar (Prime Minister -- Estonia)

U.S. Representative Dick Armey, "[Estonian Prime Minister] Mart Laar came to my office the other day to recount his country's remarkable transformation. He described a nation of people wh are harder-working, more virtuous -- yes, more virtuous, because the market punishes immorality -- and more hopeful about the future than they've ever been in their history. I asked Mr. Laar where his government got the idea for these reforms. Do you know what he replied? He said, 'We read Milton Friedman and F. A. Hayek'." (Dick Armey, "Address at the Dedication of the Hayek Auditorium", Cato Institution, Washington, D.C., May, 9, 1995.)

Vaclav Klaus (Prime Minister - Czech Republic)

"I was 25 years old and pursuing my doctorate in economics when I was allowed to spend six months of post-graduate studies in Naples, Italy. I read the Western economic textbooks and also the more general work of people like Hayek. By the time I returned to Czechoslovakia, I had an understanding of the principles of the market. In 1968, I was glad at the political liberalism of the Dubcek Prague Spring, but was very critical of the Third Way they pursued in economics." (Vaclav Klaus, "No Third Way Out: Creating a Capitalist Czechoslovakia", Reason, 1990, (June): 28-31).

Milton Friedman* (Hoover Institution)

"There is no figure who had more of an influence, no person had more of an influence on the intellectuals behind the Iron Curtain than Friedrich Hayek. His books were translated and published by the underground and black market editions, read widely, and undoubtedly influenced the climate of opinion that ultimately brought about the collapse of the Soviet Union."

*Nobel Prize Winner in Economics.

Hayek's Influence on 20th Century Political Economy .

Armen Alchian* (Economics, UCLA)

"ALCHIAN: Two things you [Hayek] wrote that had a personal influence on me, after your Prices and Production, were 'Individualism and Economic Order' [sic -- Alchian certainly has in mind Hayek's 'Economics and Knowledge'] and 'The Use of Knowledge in Society.' These I would regard as your two best articles, best in terms of their influence on me. HAYEK: 'Economics and Knowledge' -- the '37 one -- which is reprinted in the volume, is the one which marks the new look at things in my way. ALCHIAN: It was new to you, too, then? Was it a change in your own thinking? HAYEK: Yes, it was really the beginning of my looking at things in a new light . .. I was aware that I was putting down things which were fairly well known in a new form, and perhaps it was the most exciting moment in my career when I saw it [i.e. 'Economics and Knowledge'] in print. ALCHIAN: Well, I'm delighted to hear you say that, because I had that copy typed up to mimeograph for my students in the first course I gave here [i.e. UCLA]. And Allan Wallace . . came through town one day, and I said, 'Allan, I've got a great article!" He looked at it, started to laugh, and said, "I've seen it too; it's just phenomenal!' I'm just delighted to hear you say that it was exciting, because it was to me, too . . that was a very influential article, I must say .. ".

*Alchian is the author of the influential article "Uncertainty, Evolution and Economic Theory", and co-author of the bestselling textbook University Economics.

Ronald Coase* (Economics, U. of Chicago)

"In fact, a large part of what we think of as economic activity is designed to accomplish what high transaction costs would otherwise prevent or to reduce transaction costs so that individuals can negotiate freely and we can take advantage of that diffused knowledge of which Friedrich Hayek has told us." (Ronald Coase, Nobel Memorial Prize Lecture, "The Institutional Structure of Production", Essays on Economics and Economists, Chicago: U. of Chicago Press, 1994, p. 9)

*Nobel Prize Winner in Economics.

Roy Harrod* (Economic, Cambridge)

John Hicks, "It is not so well known that it [Keynes's and my own move from thinking in terms of price-levels and the rate of interest to thinking in terms of inputs and outputs] is matched by a movement from Hayek to Harrod. I once asked Harrod what had put him on to the construction of his so-call 'dynamic' theory; he said, to my surprise, that it was thinking about Hayek." (J. Hicks, 1982, pp. 340-341)

*Leading figure in the development of 'Keynesian Economics' and 'Dynamic Theory'.

John Hicks* (Economics, Oxford)

"I can date my own personal 'revolution' rather exactly to May or June 1933. It was like this. It began . . with Hayek. His Prices and Production is one of the influences that can be detected in The Theory of Wages; it could not have been otherwise, for 1931 was a Prices and Production year at the London School of Economics . . I did not in fact find it all easy to fit in with my own ideas. What started me off in 1933 was an earlier work of Hayek's, his paper on 'Intertemporal Equilibrium', an idea which I found easier to reduce to my preferred (Paretian or Wicksellian) pattern." (John Hicks, The Theory of Wages, 2nd Edition,1963, p. 307)

".. it was from Hayek that I began [the breakthrough essay "Equilibrium and the Cycle" (1933), the original beginnings of Hick's influential work on the topics of intertemporal equilibrium, monetary theory, and trade cycle phenomena] ". (John Hicks, Money, Interest and Wages, Cambridge: Harvard U. Press, 1982, p. 28).

"There were four years, 1931-1935, when I was myself a member of [Hayek's] seminar in London; it has left a deep mark on my thinking." (John Hicks, Classics and Moderns, New York: Basil Blackwell, 1983, p. 97).

B. Ingrao & G. Israel, "Hicks elaborated the concept of temporary equilibrium, perhaps the most original contribution of Value and Capital, following the path laid down by Hayek and the Swedish school." (B. Ingrao & G. Israel, 1990, p. 239)

"Hayek was making us think of the productive process as a process in time, inputs coming before outputs ..". (John Hicks, Classics and Moderns, New York: Basil Blackwell, 1983, p. 359).

Leonid Hurwicz* (Economics, U. of Minnesota)

"I am in complete sympathy with [Kirzner's] point of departure, namely, the emphasis on the dispersion of information among economic decision-making units (called by him, 'Hayek's knowledge problem') and the consequent problem of transmission of information among those units. Much of my own research work since the 1950s has been focused on issued in welfare economics viewed from an informational perspective. The ideas of Hayek (whose classes at the London School of Economics I attended during the academic year 1938-39) have played a major role in influencing my thinking and have been so acknowledged." (L. Hurwicz, 1984, p. 419)

*Leading developer of the economics of information and incentive compatibility.

John Maynard Keynes* (Economics, Cambridge)

"Keynes was shortly to develop his own approach to the general task identified by Hayek [.e.g the task of monetary theory], under the rubric of 'A Monetary Theory of Production' (Keynes, 1973, pp. 381, et seq.)." (A. Cottrell, 1994, p. 199)

"I am in full agreement, also, with Dr. Hayek's rebuttal of John Stuart Mill's well-known dictum that 'there cannot, in short, be intrinsically a more insignificant thing, in the economy of society, than money,' [when Hayek writes]: "it means also that the task of monetary theory is a much wider one than is commonly assumed; that its task is nothing less than to cover a second time the whole field which is treated by pure theory under the assumption of barter, and to investigate what changes in the conclusions of pure theory are made necessary by the introduction of indirect exchange. The first step towards a solution of this problem is to release monetary theory from the bonds which a too narrow conception of its task has created.'" (John Maynard Keynes, "The Pure Theory of Money: A Reply to Dr. Hayek", Economica, Nov. 1931, pp. 395-396.)

*Leading 20th Century Economist in the English tradition of Marshall, Marx, Malthus, and Mill.

Theodore Lowi* (Political Science, Cornell)

".. although he is very probably unaware of this book and of my work in general, I want to express a very belated thanks to Friedrich A. Hayek. His work had much more of an influence on me than I realized during the writing of the First Edition [of The End of Liberalism] I neither began nor ended as a Hayekist but instead found myself confirming, by process of elimination and discovery, many of his fears about the modern liberal state." (Theodore Lowi, 'Preface to the Second Edition', in The End of Liberalism, 2nd Edition, New York: W. W. Norton, 1979, p. xiv).

*According to a survey of the Am. Pol Sci. Assoc. Lowi is regarded as the political scientist who made the most significance contribution to political science during the 1970s.

Robert Nozick* (Harvard University)

"While in graduate school I encountered the writings of Friedrich Hayek and Ludwig von Mises, which shook me out of my then socialist beliefs. There was Hayek's book of essays, Individualism and Economic Order, and Mises's wide-ranging and unsettling Socialism, which showed me I had not thought through any details -- economic, social or cultural -- of how socialism would work. One of their arguments in particular, about the impossibility of rational economic calculation under socialism, dumbfounded me. Whether or not the argument was ultimately judged to be correct, it was amazing, something I never would have thought of in a million years." (Robert Nozick, "Robert Nozick", The Harvard Guide to Influential Books: 113 Distinguished Harvard Professors Discuss the Books That Have Helped to Shape Their Thinking, New York: Harper & Row, 1986, p. 187).

*Nozick is a leading writer on the problems of social justice and moral philosophy.

Thomas Sowell* (Hoover Institution)

"If one writing contributed more than any other to the framework in which this work [Sowell's Knowledge and Decisions] developed, it would be an essay entitled 'The Use of Knowledge in Society,' published in the American Economic Review of September 1945, and written by F. A. Hayek . . In this plain and apparently simple essay was a deeply penetrating insight into the way societies function and malfunction, and clues as to why they are so often and so profoundly misunderstood." (Thomas Sowell, Knowledge and Decisions, New York: Basic Books, 1980, p. ix)

*Sowell is a leading historian of economic thought, and an internationally recognized authority on the problems of race, politics, and culture.

Miles Taylor

"During the following decade [of the 1950's] modern economic history took a dramatic swing away from the liberal-left consensus established by the Hammonds, Tawney and the Webbs. The seminal text for this change of direction was the 1954 collection of essays compiled by F. A. Hayek, Capitalism and the Historians . . . ".

Hayek and the Law.

Richard Epstein * (U. of Chicago School of Law)

"[I] think that permanence and stability are the cardinal virtues of the legal rules that make private innovation and public progress possible. To my mind there is no doubt that a legal regime that embraced private property and freedom of contract is the only one that in practice can offer that permanence and stability .. In reaching this conclusion, I have been heavily influenced by the work of Friedrich Hayek." (Richard Epstein, Simple Rules for a Complex World, Cambridge: Harvard U. Press.)

*Epstein is one of the leading legal theorists in America.

Hayek and the London School of Economics.

Arnold Plant* (Economics, L.S.E.)

"I can testify from personal experience to the immense stimulus and direction which Hayek's migration to this country [Great Britain] gave to economic research in the 1930s, not only in London and economics faculties throughout the United Kingdom, but also in the international world of scholarship." (Arnold Plant, "A Tribute to Hayek -- the Rational Persuader", Economic Age, Jan.-Feb., 1970)

*Influential teacher of Nobel Prize winner Ronald Coase, among others.

Ronald Coase* (Law & Economics, U. of Chicago)

"I will be discussing what happened in economics in England, but these were times when, to a very considerable extent, this was what happened in economics. The first episode I will discuss is local, but the economists involved were among the best in the world. In February 1931, Friedrich Hayek gave a series of public lectures entitled 'Prices and Production' at the London School of Economics . . They were undoubtably the most successful set of public lectures given at LSE during my time there, even surpassing the brilliant lectures Jacob Viner gave on international trade theory. The audience, notwithstanding the difficulties of understanding Hayek, was enthralled. What was said seemed to us of great importance and made us see things of which we had previously been unaware. After hearing these lectures, we knew why there was a depression. Most students of economics at LSE and many members of the staff became Hayekians or, at any rate, incorporated elements of Hayek's approach in their own thinking. With the arrogance of youth, I myself expounded the Hayekian analysis to the faculty and students at Columbia University in the fall of 1931."

"The [seminar in economic theory conducted by Hayek at the L.S.E. in the 1930s] was attended, it came to seem, by all of the economists of my generation -- Nicky [Kaldor], Thomas Balogh, L. K. Jah, Paul Rosenstein-Rodan, the list could be indefinitely extended. The urge to participate (and correct Hayek) was ruthlessly competitive." (J. K.

*Nobel Prize winner in Economics.

Douglass North* (Economics, Washington U.)

"Information costs are reduced by the existence of large numbers of buyers and sellers.

Richard Nelson* (Economics, Yale) & Sidney Winter* (Economics, Yale)

"The dilemma of a socialized system is that the information flow overwhelms a centralized system if it is open to new ideas and data, that closing the system and forcing the plan to work forecloses alternatives and risks unhedged mistakes, and that decentralizing without real markets poses the problems discussed by Hayek.

Hayek and the Problem of Spontaneous Order.

Jon Elster* (Columbia)

"The investigation of this problem -- How is spontaneous order possible? -- is sometimes referred to as the 'Hayek programme'. (Footnote 7 -- See notably Hayek (1978), vol. 1-3. For comments, see Gray (1986) and Vanberg (1986).) The present analysis differs in two ways from most other attempts to implement the programme. (Footnote 8 -- Attempt to implement the Hayek programme include those of Nozick (1974), Ullman-Margalit (1977), Schotter (1981), Hardin (1982), Axelrod (1984), Sugden (1986) and M. Taylor (1987).)."

Douglass North* (Washington U., Economics)

"Regarding social order, [Francis] Fukuyama writes, "The systematic study of how order, and thus social capital, can emerge in spontaneous and decentralized fashion is one of the most important intellectual developments of the late twentieth century." He correctly attributes the modern origins of this argument to F.A. Hayek, whose pioneering contributions to cognitive science, the study of cultural evolution, and the dynamics of social change put him in the forefront of the most creative scholars of the 20th century."

Hayek, Path Dependence and Complexity Theory in Economics.

Brian Arthur* (Economics, Santa Fe Institute)

"Right after we published our first findings [on the implications of path dependence and complexity theory for economics], we started getting letters from all over the country saying, 'You know, all you guys have done is rediscover Austrian economics' .. I admit I wasn't familiar with Hayek and von Mises as the time. But now that I've read them, I can see that this is essentially true."

Hayek & the Origin of the Intertemporal Equilibrium Construction.

Bruna Ingrao* (Economics, U. of Sassari) & Giorgio Israel* (Mathematics, U. of Rome)

"Hayek made a suggestion that was to be of great importance in the theory's [i.e. General Equilibrium Theory or 'GET'] subsequent history, that the same goods available at two different moments of time should be treated as distinct goods whose relations of exchange were to be examined, although they might, 'technically speaking,' be one and the same product." (Bruna Ingrao & Giorgio Israel, The Invisible Hand: Economic Equilibrium in the History of Science, 1990, p. 232)

"[Hayek] did contribute toward an important conceptual development in his reflections on the problems raised by extending the analysis of equilibrium in time. In a key article of 1928 published in the 'Weltwirtschafliches Archiv,' he observed that it was not possible to ignore the element of time in the simultaneous determination of prices if analysis was to be extended to monetary phenomena. {quotes Hayek} Hayek defined the problem concisely as one of an intertemporal system of prices. {quotes Hayek}." (Bruna Ingrao & Giorgio Israel, The Invisible Hand: Economic Equilibrium in the History of Science, 1990, p. 232)

"[Hayek's] equilibrium theory offered a wealth of suggestions that were to be taken up in the literature of the 1940s and 1950s. The idea of intertemporal equilibrium, which was to be precisely defined in axiomatic terms by Arrow and Debreu, took shape in his writings of the 1920s and 1930s."

Hayek and the Problem of Monetary Economics &The Trade Cycle.

Robert Lucas* (Economics, U. of Chicago)

" .. it is likely that many modern economists would have no difficulty accepting Hayek's statement of the problem [of macroeconomics] as roughly equivalent to their own. Whether or not this is so, I wish .. to argue that it should be so, or that the most rapid progress toward a coherent and useful aggregate economic theory will result from the acceptance of the problem statement as advanced by [Hayek] ..".

*Bergson is a recognized leader in the economics of comparative economic systems.

J. Bradford De Long* (Economics, UC-Berkeley)

"Hayek's adversaries -- Oskar Lange and company -- argued that a market system had to be inferior to a centrally-planned system: at the very least, a centrally-planned economy could set up internal decision-making procedures that would mimic the market, and the central planners could also adjust things to increase social welfare and account for external effects in a way that a market system could never do. Hayek, in response, argued that the functionaries of a central-planning board could never succeed, because they could never create both the incentives and the flexibility for the people-on-the-spot to exercise what Scott calls metis.

Today all economists -- even those who are very hostile to Hayek's other arguments .. agree that Hayek and company hit this particular nail squarely on the head. Looking back at the seventy-year trajectory of Communism, it seems very clear that Hayek .. [is] right: that its principal flaw is its attempt to concentrate knowledge, authority, and decision-making power at the center rather than pushing the power to act, the freedom to do so, and the incentive to act productively out to the periphery where the people-on-the-spot have the local knowledge to act effectively."

Armen Alchian* (Economics, UCLA)

"ALCHIAN: Two things you [Hayek] wrote that had a personal influence on me, after your Prices and Production, were 'Individualism and Economic Order' [sic -- Alchian certainly has in mind Hayek's 'Economics and Knowledge'] and 'The Use of Knowledge in Society.' These I would regard as your two best articles, best in terms of their influence on me. HAYEK: 'Economics and Knowledge' -- the '37 one -- which is reprinted in the volume, is the one which marks the new look at things in my way. ALCHIAN: It was new to you, too, then? Was it a change in your own thinking? HAYEK: Yes, it was really the beginning of my looking at things in a new light . .. I was aware that I was putting down things which were fairly well known in a new form, and perhaps it was the most exciting moment in my career when I saw it [i.e. 'Economics and Knowledge'] in print. ALCHIAN: Well, I'm delighted to hear you say that, because I had that copy typed up to mimeograph for my students in the first course I gave here [i.e. UCLA]. And Allan Wallace . . came through town one day, and I said, 'Allan, I've got a great article!" He looked at it, started to laugh, and said, "I've seen it too; it's just phenomenal!' I'm just delighted to hear you say that it was exciting, because it was to me, too . . that was a very influential article, I must say .. ".

Allan Meltzer* (Economics, Carnegie Mellon U.)

"Q. [McCallum] .. are there other economists who have had a really major influence on your thinking? A. [Melzer] Well I mentioned Hayek. There are two ways. One is because of my interest in political economy. The other way is that Hayek was a pioneer in the use of information in economics. One of the papers that Karl and I wrote together that I continue to like was a paper called "The Uses of Money". In that paper we tried to incorporate information and the cost of information to explain why people use money. One of Hayek's most basic ideas is that institutions are a way of reducing uncertainty. Man struggles to find institutional arrangements which on average make life a bit more predictable. Our "Uses of Money" is not so much about money as we conventionally think about it, it's about the idea of a medium of exchange, the function of an institution called the medium of exchange and how the medium of exchange as an institution resolves a part of peoples uncertainty about the future."

Informal discussions with colleagues and friends stimulated a greater interest, which was reinforced by Friedrich Hayek's powerful book The Road to Serfdom, by my attendance at the first meeting of the Mont Pelerin Society in 1947, and by discussions with Hayek after he joined the university faculty in 1950. In addition, Hayek attracted an exceptionally able group of students who were dedicated to a libertarian ideology. They started a student publication, The New Individualist Review, which was the outstanding libertarian journal of opinion for some years. I served as an adviser to the journal and published a number of articles in it .. ". (Milton & Rose Friedman, Two Lucky People: Memoirs, Chicago: U. of Chicago Press, 1998. p. 333).

"There were four years, 1931-1935, when I was myself a member of [Hayek's] seminar in London; it has left a deep mark on my thinking." (John Hicks, Classics and Moderns, New York: Basil Blackwell, 1983, p. 97).

"Hayek was making us think of the productive process as a process in time, inputs coming before outputs ..". (John Hicks, Classics and Moderns, New York: Basil Blackwell, 1983, p. 359).

"At the end of the discussions in that seminar [Hayek's L.S.E seminar] .. we were, I believe, on the point of taking what now seems to me to be a decisive step. I was, at least, on the point of taking it myself. There is evidence for that in my Value and Capital, much of the groundwork for which was done before I left London .." (John Hicks, Classics and Moderns, New York: Basil Blackwell, 1983, p. 97).

"I remember Robbins asking me if I could turn the Hayek model into mathematics .. it began to dawn on me that .. the model must be better specified. It was claimed that, if there were no monetary disturbance, the system would remain in 'equilibrium'. What could such an equilibrium mean? This, as it turned out, was a very deep question; I could do no more, in 1932, than make a start at answering it. I began by looking at what had been said by .. Pareto and Wicksell. Their equilibrium was a static equilibrium, in which neither prices nor outputs were changing .. That, clearly, would not do for Hayek. His 'equilibrium' must be progressive equilibrium, in which real wages, in particular, would be rising, so relative prices could not remain unchange .. The next step in my thinking, was .. equilibrium with perfect foresight. Investment of capital, to yield its fruit in the future, must be based on expectations, of opportunities in the future. When I put this to Hayek, he told me that this was indeed the direction in which he had been thinking. Hayek gave me a copy of a paper on 'intertemporal equilibrium', which he had written some years before his arrival in London; the conditions for a perfect foresight equilibrium were there set out in a very sophisticated manner." (John Hicks, Money, Interest and Wages, Cambridge: Harvard U. Press, 1982, pp. 6-7).

"I can date my own personal 'revolution' rather exactly to May or June 1933. It was like this. It began . . with Hayek. His Prices and Production is one of the influences that can be detected in The Theory of Wages; it could not have been otherwise, for 1931 was a Prices and Production year at the London School of Economics . . I did not in fact find it all easy to fit in whith my own ideas. What started me off in 1933 was an earlier work of Hayek's, his paper on 'Intertemporal Equilibrium', an idea which I found easier to reduce to my preferred (Paretian or Wicksellian) pattern." (John Hicks, The Theory of Wages, 2nd Edition,1963, p. 307)

Arnold Plant* (Economics, L.S.E.)

"I can testify from personal experience to the immense stimulus and direction which Hayek's migration to this country [Great Britain] gave to economic research in the 1930s, not only in London and economics faculties throughout the United Kingdom, but also in the international world of scholarship." (Arnold Plant, "A Tribute to Hayek -- the Rational Persuader", Economic Age, Jan.-Feb., 1970)

*Influential teacher of Nobel Prize winner Ronald Coase, among others.

Thomas Sowell* (Hoover Institution)

"If one writing contributed more than any other to the framework in which this work [Sowell's Knowledge and Decisions] developed, it would be an essay entitled 'The Use of Knowledge in Society,' published in the American Economic Review of September 1945, and written by F. A. Hayek . . In this plain and apparently simple essay was a deeply penetrating insight into the way societies function and malfunction, and clues as to why they are so often and so profoundly misunderstood." (Thomas Sowell, Knowledge and Decisions, New York: Basic Books, 1980, p. ix)

*Sowell is a leading historian of economic thought, and an internationally recognized authority on the problems of race, politics, and culture.

Irving Kristol* (editor, The Public Interest)

".. the most intelligent defender of capitalism [in the modern period is Friedrich Hayek]."

*Kristol is well-known as the intellectual leader of the 'neo-conservatives' in America.

John Gray* (European Thought, LSE)

"No-one who knows Hayek's work can doubt that his attempt to restate liberal principles in a form appropriate to the circumstances and temper of the twentieth century has yielded a body of insights wholly comparable in profundity and power with those of his forebears in the classical liberal tradition."

"Hayek's work composes a system of ideas, fully as ambitious as the systems of Mill and Marx, but far less vulnerable to criticism than theirs because it is grounded on a philosophically defensible view of the scope and limits of human reason."

*Gray is a leading specialist in political theory.

Ronald Hamowy* (Intellectual History, U. of Alberta)

"At the time of his death, F. A. Hayek was unquestionably the world's preeminent spokesman for classical liberalism and its most important thinker." (Ronald Hamowy, "F. A. Hayek, on the Occasion of the Centenary of his Birth", Cato Journal. Vol. 9, No. 2. Fall, 1999).

*Hamowy is a specialist in the history of liberal thought.

Hayek's The Road to Serfdom.

Alan Brinkley * (History, Columbia)

"The publication of two books .. helped to galvanize the concerns that were beginning to emerge among intellectuals (and many others) about the implications of totalitarianism. One was James Burnham's The Managerial Revolution .. [A second] Friedrich A. Hayek's The Road to Serfdom .. was far more controversial -- and influential. Even more than Burnham, Hayek forced into public discourse the question of the compatibility of democracy and statism .. In responding to Burnham and Hayek .. liberals [in the statist sense of this term as used by some in the United States] were in fact responding to a powerful strain of Jeffersonian anti-statism in American political culture .. The result was a subtle but important shift in liberal [i.e. American statist] thinking."

*Brinkley is a leading authority on intellectual currents in 20th century American politics.

E. J. Dionne, Jr.* (commentatory, The Washington Post)

".. the publication of Friedrich A. von Hayek's The Road to Serfdom in 1944 [is rightly seen] as the first shot in the intellectual battle that was to turn the tide in favor of conservatism [i.e. non-statist liberalism]."

*Dionne is a well-known popular writer on contemporary intellectual trends in American politics.

Hayek's The Constitution of Liberty.

Irving Kristol* (editor, The Public Interest)

".. the most intelligent defender of capitalism today [is Friedrich Hayek] ..Hayek .. has as fine and as powerful a mind as is to be found anywhere, and [his] Constitution of Liberty is one of the most thoughtful works of the last decades."

"It is in good part because of Professor Hayek's work [on the topic of social engineering], and also because of his profound insights -- most notably in The Constitution of Liberty -- into the connection between a free market, the rule of law, and individual liberty, that you don't hear professors saying today, as they used so glibly to say, that 'we are all socialists now.'

*Kristol is well-known as the intellectual leader of the 'neo-conservatives' in America.
