Libertarian Economics

Here's a list I compiled of important libertarian economic concepts. Feedback on this list would be appreciated. Do you know of any other passages which more effectively/efficiently convey any of these concepts? Are there any important concepts that I have not included?

Scarcity...

The first lesson of economics is scarcity: There is never enough of anything to satisfy all those who want it. The first lesson of politics is to disregard the first lesson of economics. - Thomas Sowell

Opportunity cost...

The concept of opportunity cost (or alternative cost) expresses the basic relationship between scarcity and choice. If no object or activity that is valued by anyone is scarce, all demands for all persons and in all periods can be satisfied. There is no need to choose among separately valued options; there is no need for social coordination processes that will effectively determine which demands have priority. In this fantasized setting without scarcity, there are no opportunities or alternatives that are missed, forgone, or sacrificed. - James M. Buchanan

Human action...

We call contentment or satisfaction that state of a human being which does not and cannot result in any action. Acting man is eager to substitute a more satisfactory state of affairs for a less satisfactory. His mind imagines conditions which suit him better, and his action aims at bringing about this desired state. The incentive that impels a man to act is always some uneasiness. A man perfectly content with the state of his affairs would have no incentive to change things. He would have neither wishes nor desires; he would be perfectly happy. He would not act; he would simply live free from care. - Mises, The Prerequisites of Human Action

Demonstrated preference...

The concept of demonstrated preference is simply this: that actual choice reveals, or demonstrates, a man’s preferences; that is, that his preferences are deducible from what he has chosen in action. Thus, if a man chooses to spend an hour at a concert rather than a movie, we deduce that the former was preferred, or ranked higher on his value scale. Similarly, if a man spends five dollars on a shirt we deduce that he preferred purchasing the shirt to any other uses he could have found for the money. This concept of preference, rooted in real choices, forms the keystone of the logical structure of economic analysis, and particularly of utility and welfare analysis. - Rothbard, Toward a Reconstruction of Utility and Welfare Economics

Incentives matter...

Difficulties and hardships are often but an incentive to exertion: what is fatal to it, is the belief that it will not be suffered to produce its fruits. - J.S. Mill

The Invisible Hand...

The man of system, on the contrary, is apt to be very wise in his own conceit; and is often so enamoured with the supposed beauty of his own ideal plan of government, that he cannot suffer the smallest deviation from any part of it. He goes on to establish it completely and in all its parts, without any regard either to the great interests, or to the strong prejudices which may oppose it. He seems to imagine that he can arrange the different members of a great society with as much ease as the hand arranges the different pieces upon a chess-board. He does not consider that the pieces upon the chess-board have no other principle of motion besides that which the hand impresses upon them; but that, in the great chess-board of human society, every single piece has a principle of motion of its own, altogether different from that which the legislature might chuse to impress upon it. If those two principles coincide and act in the same direction, the game of human society will go on easily and harmoniously, and is very likely to be happy and successful. If they are opposite or different, the game will go on miserably, and the society must be at all times in the highest degree of disorder. - Adam Smith

Fallibilism...

It follows, then, that a less centralized society has the advantage of a greater diversification of its performance across a larger number of preceptors. This is because diversification here dilutes the impact of the ability, or the lack thereof, of each preceptor on the aggregate societal performance. - Raaj K. Sah

The curious task of economics is to demonstrate to men how little they really know about what they imagine they can design. - Hayek

Apparently, then, the legislators and the organizers have received from Heaven an intelligence and virtue that place them beyond and above mankind; if so, let them show their titles to this superiority. - Bastiat

Consequences of failure...

For this is the salient point: private organizations, whether for-profit or non-profit, perform or lose their customers or their donors. When a private entity fails to deliver on its promise, or actually causes harm, it is held liable for the failure and pays the damages. When government fails, it gets a bigger budget and even more power. - Mary L. G. Theroux

Supply and Demand...

The instruments of intervention became the tools with which to apply government knowledge. Resources were directed and allocated by the state, by political and bureaucratic decision making, rather than by the elemental forces of supply and demand - forces shaped by the knowledge of those in the marketplace. - Daniel Yergin, Joseph Stanislaw

Partial knowledge...

It must be remembered, besides, that even if a government were superior in intelligence and knowledge to any single individual in the nation, it must be inferior to all the individuals of the nation taken together. It can neither possess in itself, nor enlist in its service, more than a portion of the acquirements and capacities which the country contains, applicable to any given purpose. - J.S. Mill, Principles of Political Economy with some of their Applications to Social Philosophy

The problem is thus in no way solved if we can show that all the facts, if they were known to a single mind (as we hypothetically assume them to be given to the observing economist), would uniquely determine the solution; instead we must show how a solution is produced by the interactions of people each of whom possesses only partial knowledge. To assume all the knowledge to be given to a single mind in the same manner in which we assume it to be given to us as the explaining economists is to assume the problem away and to disregard everything that is important and significant in the real world. - Hayek, The Use of Knowledge in Society

It is a world of change in which we live, and a world of uncertainty. We live only by knowing something about the future; while the problems of life, or of conduct at least, arise from the fact that we know so little. This is as true of business as of other spheres of activity. The essence of the situation is action according to opinion, of greater or less foundation and value, neither entire ignorance nor complete and perfect information, but partial knowledge. - Frank Knight, Risk, Uncertainty, and Profit

Other people's money...

There are four ways to spend money. You can spend your own money on yourself. When you do that, why you really watch out for what you're doing, and you try to get the most for your money. Then you can spend your own money on somebody else. For example, I buy a birthday present for someone. Well then, I'm not so careful about the content of the present, but I'm very careful about the cost. Then, I can spend somebody else's money on myself. And if I spend somebody else's money on myself, then I'm going to have a good lunch! Finally, I can spend somebody else's money on somebody else. And if I spend somebody else's money on somebody else, I'm not concerned about how much it costs, and I'm not concerned about what I get. And that's government. And that's close to 40 percent of our national income. - Milton Friedman, The 4 Ways to Spend Money

Unintended consequences...

In the economic sphere an act, a habit, an institution, a law produces not only one effect, but a series of effects. Of these effects, the first alone is immediate; it appears simultaneously with its cause; it is seen. The other effects emerge only subsequently; they are not seen; we are fortunate if we foresee them.

There is only one difference between a bad economist and a good one: the bad economist confines himself to the visible effect; the good economist takes into account both the effect that can be seen and those effects that must be foreseen.

Yet this difference is tremendous; for it almost always happens that when the immediate consequence is favorable, the later consequences are disastrous, and vice versa. Whence it follows that the bad economist pursues a small present good that will be followed by a great evil to come, while the good economist pursues a great good to come, at the risk of a small present evil. - Bastiat, The Seen vs the Unseen

Individual foresight...

The resource status of material objects is therefore always problematical and depends to some extent on foresight. An object constitutes wealth only if it is a source of an income stream. The value of the object to the owner, actual or potential, reflects at any moment its expected income-yielding capacity. This, in its turn, will depend on the uses to which the object can be turned. The mere ownership of objects, therefore, does not necessarily confer wealth; it is their successful use which confers it. Not ownership but use of resources is the source of income and wealth. An ice-cream factory in New York may mean wealth to its owner; the same ice-cream factory in Greenland would scarcely be a resource. - Lachmann, The Market Economy and the Distribution of Wealth

If the socialists mean that under extraordinary circumstances, for urgent cases, the state should set aside some resources to assist certain unfortunate people, to help them adjust to changing conditions, we will, of course, agree. This is done now; we desire that it be done better. There is, however, a point on this road that must not be passed; it is the point where governmental foresight would step in to replace individual foresight and thus destroy it. - Bastiat, Justice and Fraternity

There is no need to prove that each individual is the only competent judge of this most advantageous use of his lands and of his labor. He alone has the particular knowledge without which the most enlightened man could only argue blindly. He alone has an experience which is all the more reliable since it is limited to a single object. He learns by repeated trials, by his successes, by his losses, and he acquires a feeling for it which is much more ingenious than the theoretical knowledge of the indifferent observer because it is stimulated by want. - Turgot

Entrepreneurship...

Entrepreneurship is necessary in economic development, therefore, for the quite pedestrian purpose of ensuring a tendency towards the adoption of the socially advantageous long-term capital-using opportunities available. So far from being a kind of exogenous push given to the economy, entrepreneurial innovation is the grasping of opportunities that have somehow escaped notice. - Kirzner, Entrepreneurship & the Market Approach to Development

Heterogeneous activity...

So far as this is the case, it is evident that government, by excluding or even by superseding individual agency, either substitutes a less qualified instrumentality for one better qualified, or at any rate substitutes its own mode of accomplishing the work, for all the variety of modes which would be tried by a number of equally qualified persons aiming at the same end; a competition by many degrees more propitious to the progress of improvement than any uniformity of system. - J.S. Mill, Principles of Political Economy with some of their Applications to Social Philosophy

Market redistribution...

These economic facts have certain social consequences. As the critics of the market economy nowadays prefer to take their stand on “social” grounds, it may be not inappropriate here to elucidate the true social results of the market process. We have already spoken of it as a leveling process. More aptly, we may now describe these results as an instance of what Pareto called “the circulation of elites.” Wealth is unlikely to stay for long in the same hands. It passes from hand to hand as unforeseen change confers value, now on this, now on that specific resource, engendering capital gains and losses. The owners of wealth, we might say with Schumpeter, are like the guests at a hotel or the passengers in a train: They are always there but are never for long the same people. - Lachmann, The Market Economy and the Distribution of Wealth

Creative destructionism...

As protected firms become less innovative, a country’s overall economic growth may suffer. This is because, as Schumpeter emphasized nearly a century ago, economic growth thrives on “creative destruction.” In a healthy economy, new firms constantly arise to challenge older, less-innovative behemoths. - Matthew Mitchell, The Pathology of Privilege: The Economic Consequences of Government Favoritism

The interests of consumers...

Treat all economic questions from the viewpoint of the consumer, for the interests of the consumer are the interests of the human race. - Bastiat, Abundance and Scarcity

Dollar voting...

The capitalist society is a democracy in which every penny represents a ballot paper. - Mises

Foot voting...

The second broad principle is that government power must be dispersed. If government is to exercise power, better in the county than in the state, better in the state than in Washington. If I do not like what my local community does, be it in sewage disposal, or zoning, or schools, I can move to another local community, and though few may take this step, the mere possibility acts as a check. If I do not like what Washington imposes, I have few alternatives in this world of jealous nations. - Milton Friedman, Capitalism and Freedom

Moral value...

Only where we ourselves are responsible for our own interests and are free to sacrifice them has our decision moral value. We are neither entitled to be unselfish at someone else's expense nor is there any merit in being unselfish if we have no choice. The members of a society who in all respects are made to do the good thing have no title to praise. - Hayek
