Economics

[Economics is] the science which studies human behavior as a relationship between scarce means which have alternative uses.

Lionel Robbins, 1932

Essay on the Nature and Significance of Economic Science

[Economics is] “…the dismal science…

Thomas Carlyle

Economics is the science of thinking in terms of models joined to the art of choosing models which are relevant to the contemporary world.

John Maynard Keynes

The theory of economics does not furnish a body of settled conclusions immediately applicable to policy. It is a method rather than a doctrine, an apparatus of the mind, a technique of thinking, which helps its possessors to draw correct conclusions.

John Maynard Keynes

Economy is the art of making the most of life.

George Bernard Shaw

Economics is a study of mankind in the ordinary business of life; it examines that part of individual and social action which is most closely connected with the attainment and with the use of the material requisites of wellbeing.

Alfred Marshall (1920)

Principles of Economics Eighth Edition

 [The study of economics is the province of] … “the overeducated in pursuit of the unknowable”.

Robert Solow

Thousands of habits of behavior and of enforced laws had to be developed over millennia to establish the nature and the minutiae of property rights before we could have buying and selling, instead of each man just taking what he wanted if only he was strong enough. ... Each set of rights begins as a conflict about what somebody is doing or wants to do which affects others... An economic transaction is a solved political problem. Economics has gained the title of queen of the social sciences by choosing solved political problems as its domain.

Abba Lerner

The Economics and Politics of Consumer Sovereignty

The social enthusiasm which revolts from the sordidness of mean streets and the joylessness of withered lives . . . is the beginning of economic science.

Arthur Cecil Pigou

The combined assumptions of maximizing behavior, market equilibrium, and stable preferences, used relentlessly and unflinchingly, form the heart of the economic approach.

Gary Becker

Price Theory p. 4 (1976)

economics itself [as a discipline] has always been partly a vehicle for the ruling ideology of each period as well as partly a method of scientific investigation.

Joan Robinson(1962

Economic Philosophy)

Economics is the study of money and why it is good.

Woody Allen

Economics is what economists do.

Jacob Viner

Too large a proportion of recent “mathematical” economics are mere concoctions, as imprecise as the initial assumptions they rest on, which allow the author to lose sight of the complexities and interdependencies of the real world in a maze of pretentious and unhelpful symbols.

John Maynard Keynes

General Theory

NY: Harcourt, Brace, 1936, p. 298.

 

Classic economic theory, based as it is on an inadequate theory of human motivation, could be revolutionized by accepting the reality of higher human needs, including the impulse to self-actualization and the love for the highest values.

Abraham Maslow

 

Economics is extremely useful as a form of employment for economists.

John Kenneth Galbraith


Economists

An economist is a man with an irrational passion for dispassionate rationality.

John Maurice Clark

[T]he age of chivalry is gone. That of sophisters, economists; and calculators has succeeded; and the glory of Europe is extinguished forever.

Edmund Burke

Reflections on the Revolution in France (1790)

To the economists--who are the trustees, not of civilization, but of the possibility of civilization.

John Maynard Keynes

The master economist must possess a rare combination of gifts. He must be a mathematician, historian, statesman, philosopher--in some degree. He must understand symbols and speak in words. He must contemplate the particular in terms of the general, and touch abstract and concrete in the same flight of thought. He must study the present in the light of the past for the purposes of the future. No part of man's nature or institutions must lie entirely outside his regard. He must be purposeful and disinterested in a simultaneous mood; as aloof and incorruptible as an artist, yet sometimes as near the earth as a politician.

John Maynard Keynes (1924)

 

It's easy to train economists. Just teach a parrot to say ‘Supply and Demand’.

Thomas Carlyle

If you laid all the economists in the country end to end, they’d never reach a conclusion.

George Bernard Shaw

An economist is a man who knows a hundred ways of making love but doesn’t know any women.

Art Buchwald

If economists could manage to get themselves thought of as humble, competent people on a level with dentists, that would be splendid.

John Maynard Keynes


Political Economy

Every recovery is hailed by an incumbent president as the result of his own wise policies, while every recession is condemned by him as the result of the mistaken policies of his predecessor.

Markets

If the market does indeed embody the sum of all human wishes, then the secret ones are just as important as the ones that are openly displayed.

Eric Schlosser

The Invisible Hand

Every individual necessarily labors to render the annual revenue of the society as great as he can. He generally indeed neither intends to promote the public interest, nor knows how much he is promoting it. He intends only his own gain, and he is in this, as in many other cases, led by an invisible hand to promote an end which was no part of his intention. By pursuing his own interest he frequently promotes that of the society more effectually than when he really intends to promote it. I have never known much good done by those who affected to trade for the public good.

Monopoly

A monopoly granted either to an individual or to a trading company has the same effect as a secret in trade or manufactures. The monopolists, by keeping the market constantly understocked, by never fully supplying the effectual demand, sell their commodities much above the natural price, and raise their emoluments, whether they consist in wages or profit, greatly above their natural rate.

Adam Smith

The Wealth of Nations, (vol. I, bk. I, ch. 7.


People of the same trade seldom meet together, even for merriment and diversion, but the conversation ends in a conspiracy against the public, or in some contrivance to raise prices. It is impossible indeed to prevent such meetings by any law which either could be executed, or would be consistent with liberty and justice.

Adam Smith

The Wealth of Nations, (vol. I, bk. I, ch. 10.)


Human Nature

Pleasure is our first and kindred good. It is the starting-point of every choice and of every aversion, and to it we come back, inasmuch as we make feeling the rule by which to judge of every good thing.

Epicurus (341–270 BC)

Greek philosopher

Letter to Menoeceus


The “greatest happiness for the greatest number”.

Helvetius


Nature has placed mankind under the governance of two sovereign masters, pain and pleasure. It is for them alone to point out what we ought to do as well as to determine what we shall do.  On the one hand, the standard of right and wrong, on the other the chain of causes and effects, are fastened to their throne.

Jeremy Bentham

An Introduction to the Principles of Morals and Legislation, x, § 4, 1780

 

The dictates of utility are neither more nor less than the dictates of the most extensive and enlightened (that is, well-advised) benevolence.

Jeremy Bentham

An Introduction to the Principles of Morals and Legislation, x, § 4, 1780


The father of English innovation, both in doctrines and in institutions, is Bentham: he is the great subversive, or, in the language of continental philosophers, the great critical, thinker of his age and country.

John Stuart Mill


Good and evil, reward and punishment, are the only motives to a rational creature: these are the spur and reins whereby all mankind are set on work, and guided.

John Locke


Avarice [is the] the spur of industry.

David Hume

Political Discourses


How selfish man may be supposed, there are evidently some principles in his nature, which interest him in fortune of others, and render their happiness necessary to him, though he derives nothing from it except the pleasure of seeing it.

Adam Smith

What so great happiness as to be beloved, and to know that we deserve to be beloved? What so great misery as to be hated, and to know that we deserve to be hated?

Adam Smith

Theory of Moral Sentiments

Chapter 1

 


. . . loss of a little finger would keep the average European from sleeping through the night, but, provided he never saw them, he would snore most profoundly over the loss of millions of his brethren, and the destruction of that immense multitude seems plainly an object less interesting to him than this paltry misfortune of his own.

Adam Smith, The Theory of Moral Sentiments, 1758

(contemplating reactions to human tragedies in faraway lands)


 

It is not from the benevolence of the butcher, the brewer, or the baker, that we expect our dinner, but from their regard to their own interest... This division of labor...is not originally the effect of any human wisdom, which foresees and intends that general opulence to which it gives occasion. It is the necessary, though very slow and gradual, consequence of a certain propensity to truck, barter, and exchange one thing for another.

Adam Smith

The Wealth of Nations


 

The propensity to truck, barter and exchange one thing for another is common to all men, and to be found in no other race of animals.

Adam Smith

The Wealth of Nations

 


Capitalism is based on the extraordinary belief that the nastiest of men for the nastiest of reasons will somehow work together for the benefit of us all.

John Maynard Keynes


The hedonistic conception of man is that of a lightning calculator of pleasures and pains, who oscillates like a homogeneous globule of desire ... under the impulse of stimuli that shift him about the area but leave him intact ... He is an isolated, definitive human datum, in stable equilibrium except for the buffets of the impinging forces that displace him in one direction or another ... When the force of the impact is spent, he comes to rest, a self-contained globule of desire as before.

Thorstein Veblen

On Writing

 

I don't really start until I get my proofs back from the printer. Then I can begin serious writing.

John Maynard Keynes

John Kenneth Galbraith

… [N]ever … assume that your first draft is right. The first draft, when you're writing, involves the terrible problem of thought combined with the terrible problem of composition. And it is only in the second and third and fourth drafts that you really escape that original pain and have the opportunity to get it right.

… (T)here are no propositions in economics that can't be stated in clear, plain language.

One extraordinary part of good writing is to avoid excess, which many writers do not understand. The next thing, which of course is obvious, is to be aware of the music, the symphony of words, and to make written expression acceptable to the ear.

 

John Kenneth Galbraith

Intellectual Journey, (speech)

John Kenneth Galbraith


The Bezzle

At any moment in time there exists an inventory of undiscovered embezzlement. … This inventory – it should perhaps be called the bezzle – amounts at any moment to millions [billions?] of dollars. … In good times people are relaxed, trusting and money is plentiful, but there are always many people who need more.

Under these circumstances [prosperity] the rate of embezzlement grows, the rate of discovery falls off, and bezzle increases rapidly. In depression all this is reversed. Money is watched with a narrow suspicious eye. The man who handles it is assumed to be dishonest until he proves himself otherwise. Audits are penetrating and meticulous. Commercial morality is greatly improved. The bezzle shrinks.

John Kenneth Galbraith

John Maynard Keynes

 

On Speculation

Professional investment may be likened to those newspaper competitions in which the competitors have to pick out the six prettiest faces from a hundred photographs, the prize being awarded to the competitor whose choice most nearly corresponds to the average preferences of the competitors as a whole; so that each competitor has to pick, not the faces which he himself finds the prettiest, but those which he thinks likeliest to catch the fancy of the other competitors, all of whom are looking at the problem from the same point of view. … It is not a case of choosing those which, to the best of one's judgment, are really the prettiest, nor even those which average opinion genuinely thinks the prettiest. We have reached the third degree when we devote our intelligences to anticipating what average opinion expects the average opinion to be. And there are some, I believe, who practise the fourth, fifth and higher degrees.

The Keynesian Revolution

I believe myself to be writing a book on economic theory which will largely revolutionize -- not, I suppose, at once, but in the course of the next ten years -- the way the world thinks about economic problems.

Keynes, January 1, 1935

Letter to G.B. Shaw

Those, who are strongly wedded to what I shall call “the classical theory”, will fluctuate, I expect, between a belief that I am quite wrong and a belief that I am saying nothing new. It is for others to determine if either of these or the third alternative is right.

The General Theory, p.v, 1936

There are also, I should admit, forces which one might fairly well call automatic which operate under any normal monetary system in the direction of restoring a long-run equilibrium between saving and investment. The point which I cast into doubt - though the contrary is generally believed - is whether these `automatic' forces will... tend to bring about not only an equilibrium between saving and investment but also an optimum level of production.

Collected Writings, Vol. 13, p.395, 1973

After the war, Keynes's theory was accepted as a new orthodoxy without the old one being rethought. In modern text-books, the pendulum still swings, tending toward its equilibrium point. Market forces allocate given factors of production between different uses, investment is a sacrifice of present consumption, and the rate of interest measures society's discount of the future. All the slogans are repeated unchanged. How has this trick been worked?

Collected Economic Papers, Vol. V, 1979, p.172

Joan Robinson, 1979

The “Keynesian Revolution” went off at half-cock...The equilibrists, therefore, did not know they were beaten; or rather...they did not know that they had been challenged. They thought that what Keynes had said could be absorbed into their equilibrium systems; all that was needed was that the scope of their equilibrium systems should be extended. As we know, there has been a lot of extension, a vast amount of extension; what I am saying is that it has never quite got to the point....I must say that that diagram [IS-LM] is now much less popular with me than I think it still is with many other people. It reduces the General Theory to equilibrium economics; it is not really in time. That, of course, is why it has done so well.

Sir John Hicks

“Time in Economics”

Evolution, Welfare and Time in Economics

p. 289-90, 1976

The impression of Keynes that one gains [from the Keynesians] is that of a Delphic oracle, half-hidden in billowing fumes, mouthing earth-shattering profundities whilst in a senseless trance -- an oracle revered for his powers, to be sure, but not worthy of the same respect as that accorded to the High Priests whose function it is to interpret the revelations.

Axel Leijonhufvud (1968)

On Keynesian Economics and the Economics of Keynes


Capitalism, Self Interest, and the Common Purpose

In our present confusion of aims is there enough clear-sighted public spirit left to preserve the balanced and complicated organization by which we live? Communism is discredited by events; socialism, in its old-fashioned interpretation, no longer interests the world; capitalism has lost its self-confidence. Unless men are united by a common aim or moved by objective principles, each one’s hand will be against the rest and the unregulated pursuit of individual advantage may soon destroy the whole. There has been no common purpose lately between nations or between classes, except for war…

John Maynard Keynes


Government and Government Spending

Whatsoever therefore is consequent to a time of war, where every man is enemy to every man, the same consequent to the time wherein men live without other security than what their own strength and their own invention shall furnish them withal. In such condition there is no place for industry, because the fruit thereof is uncertain: and consequently no culture of the earth; no navigation, nor use of the commodities that may be imported by sea; no commodious building; no instruments of moving and removing such things as require much force; no knowledge of the face of the earth; no account of time; no arts; no letters; no society; and which is worst of all, continual fear, and danger of violent death; and the life of man, solitary, poor, nasty, brutish, and short.

Thomas Hobbes

Thomas Hobbes

Leviathan


(Life in a state of nature is) nasty, brutish, and short.

Thomas Hobbes

Leviathan (1651)


The Limits of Property Rights:

There is a respectable and influential body of opinion which… fulminates alike against devaluations and levies, on the ground that they infringe the untouchable sacredness of contract…. Yet such persons, by overlooking one of the greatest of all social principles, namely the fundamental distinction between the right of the individual to repudiate contract and the right of the State to control vested interest, are the worst enemies of what they seek to preserve. For nothing can preserve the integrity of contract between individuals except a discretionary authority in the State to revise what has become intolerable. The powers of uninterrupted usury are great. If the accretions of vested interest were to grow without mitigation for many generations, half the population would be no better than slaves to the other half…. The absolutists of contract… are the real parents of revolution … .

John Maynard Keynes

RTB Note:  Keynes’ views on property rights echo those of Thomas Hobbes (1651, Leviathan) or Hugo Grotius.

The things [production] once there, mankind, individually or collectively, can do with them as they please. They can place them at the disposal of whomsoever they please, and on whatever terms. … Even what a person has produced by his individual toil, unaided by anyone, he cannot keep, unless by permission of society. Not only can society take it from him, but individuals could and would take it from him if society … did not … employ and pay people for the purpose of preventing him from being disturbed in [his] possession. The distribution of wealth, therefore, depends on the laws and customs of society. The rules by which it is determined are what the opinions and feelings of the ruling portion of the community make them, and are very different in different ages and countries, and might be still more different, if mankind so chose. … [emphasis added]

John Stuart Mill

Principles of Political Economy

(quoted by Robert Heilbronner, The Worldly Philosophers, p. 128-129, 7th ed.

RTB Note:  Mill believed his thoughts to be original, but in fact, his musings on property rights echo the views of Thomas Hobbes (1651, Leviathan), and even moreso, the perspectives on property rights of Hugo Grotius. Note also that Mill’s view assumes that production and income reflect historical activities [sunk costs?], so that in his implicit endorsement of redistribution, Mill ignores the disincentives for effort associated with redistribution – a position he later partially qualified.


The Importance of Ideas

The ideas of economists and political philosophers, both when they are right and when they are wrong, are more powerful than is commonly understood. Indeed, the world is ruled by little else. Practical men, who believe themselves to be quite exempt from any intellectual influences, are usually the slaves of some defunct economist. Madmen in authority, who hear voices in the air, are distilling their frenzy from some academic scribbler of a few years back. I am sure that the power of vested interests is vastly exaggerated compared with the gradual encroachment of ideas…. But, soon or late, it is ideas, not vested interests, which are dangerous for good or evil…

The Long Run

It would follow... that an arbitrary doubling of [the money stock], since this in itself is assumed not to affect [the velocity of money or the real volume of transactions] ... must have the effect of raising [the price level] to double what it would have been otherwise. The Quantity Theory is often stated in this, or a similar, form.

Now “in the long run” this is probably true. If, after the American Civil War, the American dollar had been stabilized ... ten per cent below its present value ... [the money stock] and [the price level] would now be just ten per cent greater than they actually are.... But this long run is a misleading guide to current affairs. In the long run we are all dead. [emphasis added] Economists set themselves too easy, too useless a task if in tempestuous seasons they can only tell us that when the storm is long past the ocean is flat again.

In actual experience, a change in [the money stock] is liable to have a reaction both on [the velocity of money] and on [the real volume of transactions]...

Economic Assumptions:

Unlike physics, for example, such parts of the bare bones of economic theory as are expressible in mathematical form are extremely easy compared with the economic interpretation of the complex and incompletely known facts of experience, and lead one a very little way towards establishing useful results.

John Maynard Keynes

Page after page of professional economic journals are filled with mathematical formulas leading the reader from sets of more or less plausible but entirely arbitrary assumptions to precisely stated but irrelevant theoretical conclusions.

Wassily Leontieff

...the real world is not as rational and dynamically optimal as economists would like to believe.

Robert Pindyck

It is however always important to remember that the ability to see things in their correct perspective may be, and often is, divorced from the ability to reason correctly and vice versa. That is why a man may be a very good theorist and yet talk absolute nonsense.

Joseph A. Schumpeter

It is universally appreciated, I think, that theorists are able to tweak their assumptions in order to reach any conclusion they wish. The believability of the conclusion depends not only on the fact that it was reached but on how hard the theorist had to tweak the model to get there.

Behavioral Economics

Economics is a human science; its foundations are laid in the principles of human behavior, and consequently we must begin with some observations on the psychology of human conduct which controls economic life. … . It assumes that men’s acts are ruled by conscious motives; that, as it is more ordinarily expressed, they are directed toward the “satisfaction of wants.” At the very outset the science is thus subjected to notable restrictions, since it is only to a limited extent that our behavior, even our economic behavior, [emphasis added] is of this character. Much of it is more or less impulsive and capricious. The conclusions of economic theory must in general be admitted subject to the qualification, in so far as men's economic activities are rational or planned.

Bounded Rationality

If people were as rational and forward-looking as economists assume, every chess match would yield the same result, which might be a stalemate, or perhaps white would win, or black might win. None of us is smart enough to know with certainty what that ending would be. Numerous paths might lead to the monotonously predictable ending of each game, but every counter to every possible move by an opponent would generate countermoves yielding the same inevitable result. Chess would be no more intellectually challenging than doodling or tic-tac-toe.

Some of the more egotistical of the great minds of each generation immodestly describe their discoveries and insights as timeless and universal truths. But time passes and these ultimate truths are eventually exposed as the husks of more profound truths that overlay deeper truths, previously beyond the minds eye.

Ralph Byrns [2005]

[Newton was humble about the significance of his understanding of the world. Asked one day how he had come to make his remarkable discoveries, he simply replied: "By always thinking about them."

"I do not know what I may appear to the world, "but to myself I seem to have been only like a boy playing on the seashore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me."

 

Memoirs

Isaac Newton [1642-1727]

 

The known is finite, the unknown infinite; intellectually we stand on an islet in the midst of a limitless ocean beyond comprehension. Our business in every generation is to reclaim a little more land.

Thomas H. Huxley [1887]
