"No such thing as a free lunch" (alternatively, "There ain't no such thing as a free lunch", "There is no such thing as a free lunch" or other variants, sometimes called Crane's law [1] ) is a popular adage communicating the idea that it is impossible to get something for nothing. The acronyms TANSTAAFL, TINSTAAFL, and TNSTAAFL are also used. The phrase was in use by the 1930s, but its first appearance is unknown. [2] The "free lunch" in the saying refers to the formerly common practice in American bars of offering a "free lunch" in order to entice drinking customers.
The phrase and the acronym are central to Robert A. Heinlein's 1966 science-fiction novel The Moon is a Harsh Mistress , which helped popularize it. [3] [4] The free-market economist Milton Friedman also increased its exposure and use [2] by paraphrasing it as the title of a 1975 book; [5] it is used in economics literature to describe opportunity cost. [6] Campbell McConnell writes that the idea is "at the core of economics". [7]
The "free lunch" refers to the once-common tradition of saloons in the United States providing a "free" lunch to patrons who had purchased at least one drink. Many foods on offer were high in salt (e.g., ham, cheese, and salted crackers), so those who ate them ended up buying a lot of beer. Rudyard Kipling, writing in 1891, noted how he
...came upon a bar-room full of bad Salon pictures, in which men with hats on the backs of their heads were wolfing food from a counter. It was the institution of the "free lunch" I had struck. You paid for a drink and got as much as you wanted to eat. For something less than a rupee a day a man can feed himself sumptuously in San Francisco, even though he be a bankrupt. Remember this if ever you are stranded in these parts. [8]
Some quotes exist from the time, arguing that these free lunches were not really free, such as in the Columbia Daily Phoenix of 1873: "One of the most expensive things in this city—Free lunch.", [9] L. A. W. Bulletin 1897: "If no one ever paid for drinks, there would be no 'free lunch', and the man who confines his attention to the free lunch, alone, is getting what he knows others pay for." [10] and the Washington Herald 1909: "as a matter of fact, there is no such thing as free lunch. Somebody has to pay for it." [11] When Chicago attempted to ban free lunches in 1917, Michael Montague, a saloon owner, made the case that "There is no such thing as free lunch. First of all, you have to buy something from the saloonkeeper before you can partake of the lunch. Lunch is the greatest tempering influence in the saloon. If a man takes a two-ounce drink of whisky and then takes a bite of lunch, he probably does not take a second drink. Whisky taken alone creates an appetite. If you want to create the use of whisky, pass this ordinance." [12]
TANSTAAFL, on the other hand, applies this more generally, and indicates an acknowledgement that in reality a person or a society cannot get "something for nothing". Even if something appears to be free, there is always a cost to the person or to society as a whole, although that may be a hidden cost or an externality. For example, as Heinlein has one of his characters point out, a bar offering a free lunch will likely charge more for its drinks. [13]
The earliest known occurrence of the full phrase (except for the "a"), in the form "There ain't no such thing as free lunch", appears as the punchline of a joke related in an article in the El Paso Herald-Post of June 27, 1938 (and other Scripps-Howard newspapers about the same time), entitled "Economics in Eight Words". [14] [15] According to etymologist Peter Tamony, this article was written by Walter Morrow. [16]
In 1942, "There ain't no such thing as a free lunch" appeared in Public Utilities Fortnightly, [17] and the Columbia Law Review in 1945. A shortened version of the phrase, "there is no free lunch" appeared in a 1942 article in the Oelwein Daily Register (in a quote attributed to economist Harley L. Lutz) and in a 1947 column by economist Merryle S. Rukeyser. [3] [18]
In 1949, the phrase appeared in Pierre Dos Utt's monograph TANSTAAFL: A Plan for a New Economic World Order, [19] which describes an oligarchic political system based on his conclusions from "no free lunch" principles.
The 1938 and 1949 sources use the phrase in relating a fable about a king (Nebuchadnezzar in Dos Utt's retelling) seeking advice from his economic advisors. The original 1938 version differs from Dos Utt's in that the ruler asks for ever-simplified advice following their original "eighty-seven volumes of six hundred pages" as opposed to a simple failure to agree on "any major remedy". The last surviving economist advises that "There ain't no such thing as free lunch." [20]
In 1950, a New York Times columnist ascribed the phrase to economist (and army general) Leonard P. Ayres of the Cleveland Trust Company: "It seems that shortly before the General's death [in 1946]... a group of reporters approached the general with the request that perhaps he might give them one of several immutable economic truisms that he had gathered from his long years of economic study... 'It is an immutable economic fact,' said the general, 'that there is no such thing as a free lunch.'" [21]
The September 8, 1961, issue of LIFE magazine has an editorial on page 4, "'TANSTAFL', It's the Truth", that closes with an anecdotal farmer explaining this slight variant of TANSTAAFL.
By the late 1960s, the phrase had also been given the name "Crane's law", for example in an article by Henry D. Harral in the Pennsylvanian (1969). [22]
In 1966, author Robert A. Heinlein published his novel The Moon Is a Harsh Mistress , in which TANSTAAFL was a central, libertarian theme, mentioned by name and explained. This increased its use in the mainstream. [3] [4]
Edwin G. Dolan used the phrase as the title of his 1971 book TANSTAAFL (There Ain't No Such Thing As A Free Lunch) – A Libertarian Perspective on Environmental Policy. [23]
In the sciences, no free lunch means that the universe as a whole is ultimately a closed system. There is no source of matter, energy, or light that draws resources from something else which will not eventually be exhausted. Therefore, the no free lunch argument may also be applied to natural physical processes in a closed system (either the universe as a whole, or any system that does not receive energy or matter from outside). (See Second law of thermodynamics.) The bio-ecologist Barry Commoner used this concept as the last of his famous "Four Laws of Ecology".
According to American theoretical physicist and cosmologist Alan Guth "the universe is the ultimate free lunch", given that in the early stage of its expansion the total amount of energy available to make particles was very large. [24]
In economics, no free lunch demonstrates opportunity cost. Greg Mankiw described the concept as follows: "To get one thing that we like, we usually have to give up another thing that we like. Making decisions requires trading off one goal against another." [25] The idea that there is no free lunch at the societal level applies only when all resources are being used completely and appropriately – i.e., when economic efficiency prevails. If not, a 'free lunch' can be had through a more efficient utilization of resources. Or, as Fred Brooks put it, "You can only get something for nothing if you have previously gotten nothing for something." If one individual or group gets something at no cost, somebody else ends up paying for it. If there appears to be no direct cost to any single individual, there is a social cost. Similarly, someone can benefit for "free" from an externality or from a public good, but someone has to pay the cost of producing these benefits. (See Free rider problem and Tragedy of the commons.)
In mathematical finance, the term is also used as an informal synonym for the principle of no-arbitrage. This principle states that a combination of securities that has the same cash-flows as another security must have the same net price in equilibrium.
In statistics, the term has been used to describe the tradeoffs of statistical learners (e.g., in machine learning) which are unavoidable according to the "No free lunch" theorem. That is, any model that claims to offer superior flexibility in analyzing data patterns usually does so at the cost of introducing extra assumptions, or by sacrificing generalizability in important situations. [26]
No free lunch is sometimes used as a response to claims of the virtues of free software. Supporters of free software often counter that the use of the term "free" in this context is primarily a reference to a lack of constraint ("libre") rather than a lack of cost ("gratis"). Richard Stallman has described it as " 'free' as in 'free speech', not as in 'free beer' ".
The prefix "TANSTAA-" (or "TINSTAA-") is used in numerous other contexts as well to denote some immutable property of the system being discussed. For example, "TANSTAANFS" is used by electrical engineering professors to stand for "There Ain't No Such Thing As A Noise-Free System".[ citation needed ]
Baseball Prospectus coined the abbreviation "TINSTAAPP", for "There Is No Such Thing As A Pitching Prospect", [27] as many young pitchers hurt their arms before they can be effective at a major league level.
Hungarian prime minister Ferenc Gyurcsány used this adage to justify his social reforms in the mid-2000s. As a post-socialist country, Hungary struggled with the illusion of the state as a caring and giving, independent entity, rather than being the embodiment of the community. The saying "there is no free lunch" represented that even if the state provides welfare or something else for the people in need, it is in fact bought or provided by other people of the same community through taxes. Therefore, the state cannot provide everything for everyone, and increased provisions given by the state can only be financed by economic growth, increased taxes or public debt.
Some exceptions from the "no free lunch" tenet have been put forward, such as the Sun and carbon dioxide. [28] It was argued in particular that metabolism evolved to take advantage of the free lunch provided by the Sun, which also triggers production of vital oxygen in plants. [28] However, these too fall short in that the viewpoint is an open system, Earth, with "free" inputs from the Sun. When viewed from the larger system context, the Sun/Earth or Solar System, there is no net energy exchange, and still "no free lunch". [29]

As some realist with a sense of humour remarked the other day, 'There ain't no such thing as a free lunch.' Eventually, you pay for it.
Some one recently said that Crane's Law was all one needed to know of the science of economics. Crane's Law states: 'There is no such thing as a free lunch.'
Anarcho-capitalism is an anti-statist, libertarian political philosophy and economic theory that seeks to abolish centralized states in favor of stateless societies with systems of private property enforced by private agencies, based on concepts such as the non-aggression principle, free markets and self-ownership. An anarcho-capitalist philosophy extends the concept of ownership to include control of private property as part of the self, and, in some cases, control of other people as private property. In the absence of statute, anarcho-capitalists hold that society tends to contractually self-regulate and civilize through participation in the free market, which they describe as a voluntary society involving the voluntary exchange of goods and services. In a theoretical anarcho-capitalist society a system of private property would still exist, and would be enforced by private defense agencies and/or insurance companies that were selected by property owners, whose ownership rights or claims would be enforced by private defence agencies and/or insurance companies. These agencies or companies would operate competitively in a market and fulfill the roles of courts and the police, similar to a state apparatus. Some anarcho-capitalist authors have argued that slavery is compatible with anarcho-capitalist ideals.
The Austrian school is a heterodox school of economic thought that advocates strict adherence to methodological individualism, the concept that social phenomena result primarily from the motivations and actions of individuals along with their self interest. Austrian-school theorists hold that economic theory should be exclusively derived from basic principles of human action.
David Director Friedman is an American economist, physicist, legal scholar, and anarcho-capitalist theorist. Although his academic training was in chemistry and physics and not law or economics, he is known for his textbook writings on microeconomics and the libertarian theory of anarcho-capitalism, which is the subject of his most popular book, The Machinery of Freedom. Described by Walter Block as a "free-market anarchist" theorist, Friedman has also authored several other books and articles, including Price Theory: An Intermediate Text (1986), Law's Order: What Economics Has to Do with Law and Why It Matters (2000), Hidden Order: The Economics of Everyday Life (1996), and Future Imperfect (2008).
Claude-Frédéric Bastiat was a French economist, writer and a prominent member of the French liberal school.
Milton Friedman was an American economist and statistician who received the 1976 Nobel Memorial Prize in Economic Sciences for his research on consumption analysis, monetary history and theory and the complexity of stabilization policy. With George Stigler, Friedman was among the intellectual leaders of the Chicago school of economics, a neoclassical school of economic thought associated with the work of the faculty at the University of Chicago that rejected Keynesianism in favor of monetarism until the mid-1970s, when it turned to new classical macroeconomics heavily based on the concept of rational expectations. Several students, young professors and academics who were recruited or mentored by Friedman at Chicago went on to become leading economists, including Gary Becker, Robert Fogel, and Robert Lucas Jr.
Murray Newton Rothbard was an American economist of the Austrian School, economic historian, political theorist, and activist. Rothbard was a central figure in the 20th-century American libertarian movement, particularly its right-wing strands, and was a founder and leading theoretician of anarcho-capitalism. He wrote over twenty books on political theory, history, economics, and other subjects.
Robert Anson Heinlein was an American science fiction author, aeronautical engineer, and naval officer. Sometimes called the "dean of science fiction writers", he was among the first to emphasize scientific accuracy in his fiction, and was thus a pioneer of the subgenre of hard science fiction. His published works, both fiction and non-fiction, express admiration for competence and emphasize the value of critical thinking. His plots often posed provocative situations which challenged conventional social mores. His work continues to have an influence on the science-fiction genre, and on modern culture more generally.
Ronald Harry Coase was a British economist and author. Coase was educated at the London School of Economics, where he was a member of the faculty until 1951. He was the Clifton R. Musser Professor of Economics at the University of Chicago Law School, where he arrived in 1964 and remained for the rest of his life. He received the Nobel Memorial Prize in Economic Sciences in 1991.
The Moon Is a Harsh Mistress is a 1966 science fiction novel by American writer Robert A. Heinlein about a lunar colony's revolt against absentee rule from Earth. The novel illustrates and discusses libertarian ideals. It is respected for its credible presentation of a comprehensively imagined future human society on both the Earth and the Moon.
In neoclassical economics, market failure is a situation in which the allocation of goods and services by a free market is not Pareto efficient, often leading to a net loss of economic value. The first known use of the term by economists was in 1958, but the concept has been traced back to the Victorian philosopher Henry Sidgwick. Market failures are often associated with public goods, time-inconsistent preferences, information asymmetries, non-competitive markets, principal–agent problems, or externalities.
Laissez-faire is a type of economic system in which transactions between private groups of people are free from any form of economic interventionism. As a system of thought, laissez-faire rests on the following axioms: "the individual is the basic unit in society, i.e., the standard of measurement in social calculus; the individual has a natural right to freedom; and the physical order of nature is a harmonious and self-regulating system." The original phrase was laissez faire, laissez passer, with the second part meaning "let (things) pass". It is generally attributed to Vincent de Gournay.
The Jungle Book is an 1894 collection of stories by the English author Rudyard Kipling. Most of the characters are animals such as Shere Khan the tiger and Baloo the bear, though a principal character is the boy or "man-cub" Mowgli, who is raised in the jungle by wolves. Most stories are set in a forest in India; one place mentioned repeatedly is "Seeonee" (Seoni), in the central state of Madhya Pradesh.
Free-market environmentalism argues that the free market, property rights, and tort law provide the best means of preserving the environment, internalizing pollution costs, and conserving resources.
A free lunch is the providing of a meal at no cost, usually as a sales enticement to attract customers and increase revenues from other business. It was once a common tradition in saloons and taverns in many places in the United States, with the phrase appearing in U.S. literature from about 1870 to the 1920s. These establishments included a "free" lunch, which varied from rudimentary to quite elaborate, with the purchase of at least one drink. These free lunches were typically worth far more than the price of a single drink. The saloon-keeper relied on the expectation that most customers would buy more than one drink, and that the practice would build patronage for other times of day.
Libertarian science fiction is a subgenre of science fiction that focuses on the politics and social order implied by right-libertarian philosophies with an emphasis on individualism and private ownership of the means of production—and in some cases anti-statism and anarcho-capitalism.
Libertarian paternalism is the idea that it is both possible and legitimate for private and public institutions to affect behavior while also respecting freedom of choice, as well as the implementation of that idea. The term was coined by behavioral economist Richard Thaler and legal scholar Cass Sunstein in a 2003 article in the American Economic Review. The authors further elaborated upon their ideas in a more in-depth article published in the University of Chicago Law Review that same year. They propose that libertarian paternalism is paternalism in the sense that "it tries to influence choices in a way that will make choosers better off, as judged by themselves" ; note and consider, the concept paternalism specifically requires a restriction of choice. It is libertarian in the sense that it aims to ensure that "people should be free to opt out of specified arrangements if they choose to do so". The possibility to opt out is said to "preserve freedom of choice". Thaler and Sunstein published Nudge, a book-length defense of this political doctrine, in 2008.
The following is a list of terms specific to anarchists. Anarchism is a political and social movement which advocates voluntary association in opposition to authoritarianism and hierarchy.
The following outline is provided as an overview of and topical guide to libertarianism:
Throughout modern history, a variety of perspectives on capitalism have evolved based on different schools of thought.
"To rob Peter to pay Paul", or other versions that have developed over the centuries such as "to borrow from Peter to pay Paul", and "to unclothe Peter to clothe Paul", are phrases meaning to take from one person or thing to give to another, especially when it results in the elimination of one debt by incurring another. There are many other variants and similar phrases in numerous languages. "Maneuvering the Apostles", which has the same meaning, was derived from this expression. In patchwork, "Rob Peter to pay Paul" is an alternative name for the Drunkard's Path patchwork block.
