- Module 1 of 4The Vienna School. Where does value come from, and where does money come from? The Austrian School of economics began in Vienna in the 1870s, and its founders gave answers that still matter for money.
- 1871In 1871, in his Principles of Economics, Carl Menger took on an old puzzle, the paradox of value. Water keeps us alive, yet under ordinary circumstances a pound of it has no value to us at all; a tiny fraction of a pound of diamonds, which keep no one alive, has a high one. Why?Carl Menger, Principles of Economics (Grundsätze der Volkswirtschaftslehre, 1871), trans. James Dingwall and Bert F. Hoselitz (Ludwig von Mises Institute, 2007), ch. III, pp. 140–141
- At the marginMenger’s answer: no one values water in general, only the next amount of it, given how much they already have. The first litre, which keeps you alive, is worth almost anything; the thousandth, used to wash a path, almost nothing. Water is plentiful, so the last litre counts for little; diamonds are rare, so even the last one counts. In a desert, Menger noted, more can hang on a pound of water than on a pound of gold. Value is not inside the thing, or the work that made it: it lies in the judgement of the person choosing. (The litres are the module’s illustration; Menger wrote of pounds of drinking water.)Carl Menger, Principles of Economics (Grundsätze der Volkswirtschaftslehre, 1871), trans. James Dingwall and Bert F. Hoselitz (Ludwig von Mises Institute, 2007), ch. III, pp. 140–141
- 1892Menger argued that money arose in the same way, from individual choices: traders came to accept the goods that were easiest to sell, until one was taken by everyone. No ruler had to invent it. “Money has not been generated by law”, he wrote in 1892; states recognised and regulated money later.Carl Menger, “On the Origin of Money”, Economic Journal 2(6), June 1892, section IX, p. 255
- 1949Ludwig von Mises built Menger’s ideas into a whole system. In Human Action (1949) he started from one premise: people act. They use means to reach ends they have chosen, and every choice ranks one end above another, which is given up. From that starting point, he argued, economics can be reasoned out step by step.Ludwig von Mises, Human Action: A Treatise on Economics (Yale University Press, 1949), ch. I, section 1
- 1912Long before, in The Theory of Money and Credit (1912), Mises had carried the same reasoning to money itself, and traced money’s origin to the market. Austrians argue that money’s value, like any good’s, rests on what people judge it worth, and that no decree can command it.Ludwig von Mises, The Theory of Money and Credit (Theorie des Geldes und der Umlaufsmittel, 1912)
- 1976Friedrich Hayek, Mises’s most famous student, shared the 1974 prize in economics. In Denationalisation of Money (1976) he went further than either: end the state’s monopoly on issuing money, he argued, and let currencies compete, so that the public could choose the ones that kept their value.F. A. Hayek, Denationalisation of Money: An Analysis of the Theory and Practice of Concurrent Currencies (Institute of Economic Affairs, Hobart Paper Special 70, October 1976)
- 1974Hayek shared the 1974 Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel with Gunnar Myrdal, for their work in the theory of money and economic fluctuations.The Sveriges Riksbank Prize in Economic Sciences 1974, press release (9 October 1974)
- BitcoinBitcoin is money that no one decreed. It has run since its first block on 3 JAN 2009: no authority issues it, no authority sets its value, and no one is made to accept it. People choose to hold it, as Menger’s traders chose the goods they found easiest to sell; whether it becomes money in full is up to them.Bitcoin block 0 (the genesis block), coinbase transaction
- The contrastFiat currency is money by decree: a central issuer that can always make more. Bitcoin is money by choice: no issuer, and never more than 21,000,000 coins, by a rule every node checks. Measured in fiat, its price moves, but one bitcoin is always one bitcoin: you don’t price bitcoin, you price things in it. Few prices are set in bitcoin yet, and keeping it safe takes care.
- The Bitcoin TransitionMoney by choice, not by decree.
Economics is not a single body of knowledge. It is a contested field of competing schools, each starting from different premises about what an economy is and what can be known about it. The school that dominates university curricula, central banks, and financial journalism is the Keynesian-neoclassical mainstream. The school that has most accurately predicted the failures of that mainstream is the Austrian School. This course is about the second one.
The name is geographic, not political. The school began in Vienna in the 1870s and its founding figures worked there. Its core method is not statistical modelling but deductive reasoning from self-evident premises about human action. That method produces conclusions sharply at odds with the mainstream — and, as the rest of this course will show, conclusions that map almost exactly onto why Bitcoin was built.
Carl Menger and the Marginal Revolution
The Austrian School begins with Carl Menger and his 1871 book Principles of Economics. Menger's contribution was to solve a puzzle that had defeated classical economists, including Adam Smith: the paradox of value. Why is water, essential to life, nearly free, while diamonds, useless for survival, are expensive?
The classical answer was that value came from the labour or cost embodied in a good. This answer was wrong, and its wrongness mattered, because the labour theory of value was also the foundation of Marx's critique of capitalism. Menger replaced it with the subjective theory of value: a good's value is not an intrinsic property and does not come from its cost of production. It comes from the judgment of an individual about how that specific unit of the good serves their specific purposes at a specific moment.
You do not value water in the abstract. You value the next litre of water, given how much you already have. The first litre, which keeps you alive, is worth almost anything. The thousandth litre, used to wash a path, is worth almost nothing. This is marginal value, and it dissolves the paradox. Water is cheap because the marginal litre is abundant. Diamonds are expensive because the marginal diamond is scarce. Value lives at the margin, and it lives in the mind of the actor.
This sounds abstract. It is in fact the most consequential idea in the course, because it determines what money is. If value is subjective and marginal, then money has no objective value that an authority can set or guarantee. Money is worth what individuals, acting at the margin, judge it to be worth as a medium of exchange. No decree creates that value. No central bank can manufacture it. We return to this in the discussion of why fiat fails.
Ludwig von Mises and Human Action
If Menger founded the school, Ludwig von Mises built its cathedral. Across a career spanning the early twentieth century, Mises extended Menger's subjectivism into a complete system, set out most fully in his 1949 treatise Human Action.
Mises's method was praxeology: the study of human action as purposeful behaviour. His starting point is a single premise he held to be irrefutable — that humans act, meaning they use means to achieve ends. From this one axiom, applied rigorously, an enormous structure of economic conclusions can be deduced. Action implies choice. Choice implies preference. Preference implies that the chosen end was valued above the rejected one. The passage of time between action and result implies time preference. And so on. Each step follows from the last by logic, not by measurement.
This is why Austrians are suspicious of the heavy mathematical modelling that defines mainstream economics. You cannot run a controlled experiment on an economy. You cannot hold all variables constant and vary one. The data is always contaminated by the simultaneous action of millions of people with changing preferences. Mises argued that the attempt to model economics like physics produces a false precision — equations that look rigorous but rest on assumptions (perfect information, stable preferences, equilibrium) that never hold in reality.
Mises's two most important applied conclusions, both of which have their own module in this course, are the theory of the business cycle and the impossibility of economic calculation under socialism. Both were stated decades before the events that confirmed them. We cover his 1912 monetary work in detail in What Mises Got Right About Money in 1912.
Friedrich Hayek and Dispersed Knowledge
Friedrich Hayek, Mises's most famous student, won the Nobel Prize in 1974 and carried Austrian ideas furthest into the mainstream — though never far enough to displace it. Hayek's signature contribution was the knowledge problem, the subject of this course's final module.
Hayek's insight was that the central economic problem is not the allocation of known resources — a problem a sufficiently powerful computer could in principle solve — but the use of knowledge that exists nowhere in complete form. The knowledge of how to run a particular factory, what a particular customer wants, which local supplier is reliable, what a specific patch of land is good for: this knowledge is dispersed across millions of minds, much of it tacit and impossible to articulate. No central authority can gather it. The market's price system, Hayek showed, is a mechanism for coordinating this dispersed knowledge without anyone needing to hold all of it. Prices transmit, in a single number, the net result of countless local judgments.
Hayek also wrote the book that most directly anticipates Bitcoin: 1976's Denationalisation of Money, in which he argued that the government monopoly on money should be abolished and competing private currencies allowed to emerge. We return to this at the end of the course.
The Two Schools, Side by Side
Because the Austrian School is most easily understood in contrast to the mainstream it opposes, it is worth seeing the two set against each other directly.
Keynesian vs Austrian: A Property-by-Property Comparison
Two schools of economics that have produced opposite outcomes
| Dimension | Keynesian | Austrian |
|---|---|---|
| Unit of analysis | Aggregate demand (the economy as one bathtub) | Individual choices under uncertainty |
| Role of government | Active manager — spends to fix shortfalls | Minimal — enforce contracts, leave markets alone |
| Source of recessions | Insufficient demand; "animal spirits" collapse | Credit expansion creates malinvestments that must clear |
| Recommended response | Stimulus: deficit spending + monetary easing | Let bad investments liquidate; resume on sound foundations |
| View of saving | Paradox of thrift — too much saving harms the economy | Saving is the foundation of capital formation and growth |
| View of inflation | Useful policy lever; 2% target ideal | Theft from holders; symptom of credit expansion |
| Money creation | Central bank manages the supply for policy goals | Supply should be fixed or grow only with production |
| Time horizon | Short-term: "In the long run we are all dead." | Multi-generational: civilisations are built on patience |
| Knowledge assumption | Experts can model the economy well enough to manage it | Knowledge is dispersed; central planning is impossible |
| What it produces | Larger interventions, shorter intervals, brittle systems | Painful corrections then resilient growth on real signals |
Each row describes a structural commitment, not a policy preference. Keynesian and Austrian thinking start from different premises about what the economy is and what humans can know about it. The differences compound, and produce the systems we live under.
Read down that comparison. The disagreements are not technical quibbles within a shared framework. They are foundational. The Austrians and the Keynesians disagree about what the unit of analysis is (individuals versus aggregates), what causes recessions (malinvestment versus insufficient demand), what governments should do (step back versus intervene), and what can be known (dispersed and uncapturable versus modellable by experts). Everything else follows from these starting points.
Why a Bitcoiner Should Care
It would be possible to treat all this as intellectual history — interesting, but academic. It is not academic. The Austrian School is the only major economic tradition whose conclusions Bitcoin implements. Sound money, fixed supply, no central authority able to manipulate the unit of account, prices as honest signals, the rejection of central economic planning: these are Austrian commitments, and Bitcoin enforces every one of them in code.
When you understand the Austrian framework, Bitcoin stops looking like a speculative asset and starts looking like the technical resolution of a century-old argument about money. The mainstream said money should be managed by experts for the good of the aggregate. The Austrians said money should be sound, neutral, and beyond the reach of any manager. For most of the twentieth century the mainstream won by default, because no one could build money the Austrians described. In 2009 someone did.
The remaining three modules develop the three Austrian ideas that matter most for understanding money: the business cycle, time preference and capital, and the knowledge problem. Each one, understood properly, is also an argument for why the money must be fixed.
The first lesson of economics is scarcity: there is never enough of anything to fully satisfy all those who want it. The first lesson of politics is to disregard the first lesson of economics. — Thomas Sowell, Is Reality Optional?
