Carl Menger

19 min read

Carl Menger (1840–1921) was the founder of the Austrian school of economics and one of the three independent discoverers of marginal utility theory in the 1870s. His two most important contributions to the Bitcoin-Austrian tradition are: (1) the subjective theory of value, which established that economic value is determined by individual preferences at the margin rather than by labor input or intrinsic properties; and (2) the theory of money's origin, which showed how money emerges spontaneously on the market through the property of salability — without government decree, design, or social contract. Every major argument traces back through Menger. The Bitcoin claim that money emerged from cypherpunk experimentation rather than state issuance, the salability framework that underlies hard money analysis, the methodological individualism that grounds Austrian economics, the regression theorem that Mises later formalized — all of these are Mengerian inheritances. Understanding Menger is understanding the intellectual foundation of the Austrian tradition.

Why Menger matters

Menger is the source of foundational concepts that later thinkers develop but originate with him. The intellectual debt is comprehensive:

  • Salability — the property that determines whether a good can function as money. Saifedean Ammous’s framework of “salability across scales, space, and time” is a modern decomposition of Menger’s original concept.

  • Subjective theory of value — the foundation of all Austrian economics, from which Mises, Hayek, Rothbard, Hoppe, and Ammous all begin.

  • Methodological individualism — economic explanation must reduce to individual choices, shaping how every Austrian (and Bitcoin-Austrian) argument is constructed.

  • Theory of money’s origin — money emerges on the market without state design, grounding Bitcoin’s claim to be money rather than just an asset.

  • Marginalism — value is determined at the margin, not by totals; this single insight dissolved a century of classical confusion about value.

Menger is the anchor of the lineage: every Austrian framework descends from him, and every Bitcoin argument that uses Austrian categories is implicitly invoking him.

Biographical sketch

Origins and formation

Carl Menger was born February 23, 1840, in Nowy Sącz, Galicia (then part of the Austrian Empire, now Poland). He came from an old Austrian family with military and government service traditions. His brothers Anton and Max also became prominent figures — Anton as a legal scholar, Max as a politician and economist of more interventionist sympathies than Carl.

Menger studied at the Universities of Vienna and Prague, earning his doctorate at Kraków in 1867. His early career was in journalism — he worked as a financial reporter for several newspapers, which gave him direct exposure to the gap between academic economic theory and how prices actually behaved in real markets. This empirical exposure is critical to understanding what came next.

The decisive insight

According to Menger’s own later accounts, his fundamental insight came from watching market participants. The orthodox economic theory of the time — classical economics descended from Smith, Ricardo, and Mill — held that the value of goods reflected the labor required to produce them. But Menger observed that real market participants didn’t seem to value things this way. They valued goods according to their usefulness for satisfying particular wants at particular times.

This observation grew into a comprehensive rethinking of economic value. The result was Grundsätze der Volkswirtschaftslehre (Principles of Economics), published in 1871. The book was written in remarkable solitude — Menger worked through the foundations himself, without access to the work of William Stanley Jevons (Britain) or Léon Walras (Switzerland), who were independently developing similar insights simultaneously. The three discoveries arriving within a few years became known as the Marginalist Revolution.

Academic career

The publication of Principles earned Menger a position at the University of Vienna in 1873. He taught there until 1903, training the generation of students who would become the second-generation Austrians — including Eugen von Böhm-Bawerk and Friedrich von Wieser, who would extend his framework into capital theory and price theory.

In 1876, Menger was appointed tutor to Crown Prince Rudolf of Austria-Hungary, traveling with him through Europe and giving him instruction in political economy. The lecture notes from this period survive and show Menger’s economic worldview in unusual detail.

The Methodenstreit

In 1883, Menger published Untersuchungen über die Methode der Sozialwissenschaften (Investigations into the Method of the Social Sciences), an attack on the dominant German Historical School of economics. The Historical School, led by Gustav von Schmoller, held that economics should be empirical and historical rather than theoretical and deductive — that there were no universal economic laws, only patterns specific to particular times and places.

Menger argued the opposite: that economic theory should be universal, derivable from the logic of human action, and applicable across cultures and historical periods. Schmoller responded dismissively, coining the term “Austrian school” as a slur intended to suggest provincialism. The label was adopted by its targets, who turned it into a badge of intellectual independence.

This dispute — the Methodenstreit (“methodology struggle”) — defined what made Austrian economics distinct and remains a defining feature of the school. The methodological commitments Menger defended in this dispute are what later allowed Mises to develop praxeology, what Hayek defended in his attacks on scientism, and what underlies the Austrian skepticism of mathematical aggregation in economics.

See: Austrian economics foundations.

Later life

Menger retired from teaching in 1903, partly to dedicate himself to revising Principles for a second edition that he never completed to his satisfaction. He spent two decades on this revision and accumulated extensive notes that were published posthumously by his son Karl Menger (a notable mathematician). Some of these notes contained important refinements, but the second edition Menger himself wanted never appeared.

Menger died February 26, 1921, in Vienna. He lived long enough to see his framework continued by Böhm-Bawerk and Wieser and to see Mises emerge as the third-generation leader — though he did not live to see the full flowering of the Austrian school in the twentieth century.

Major works

Principles of Economics (1871)

Menger’s foundational text. The book opens with the famous declaration that “all things are subject to the law of cause and effect” and proceeds to derive economic theory from the basic facts of human action and the satisfaction of needs.

Key contributions in this work:

  • Hierarchy of goods. Goods are classified by their distance from final consumption. First-order goods directly satisfy needs (bread). Higher-order goods are used in producing first-order goods (flour for bread, wheat for flour, land and labor for wheat). This insight allowed later Austrians (especially Böhm-Bawerk) to develop a theory of capital and the structure of production.

  • Subjective value theory. Value is not a property of goods themselves but is assigned by acting individuals based on their preferences and circumstances. This is the foundation of marginalism.

  • Marginalism. Decisions about goods are made at the margin — over the next unit, not over totals. This dissolves the classical “paradox of value” (why diamonds cost more than water) and establishes that value reflects scarcity and usefulness simultaneously.

  • Theory of money’s origin. The famous final chapter that established how money emerges on the market through salability. Treated in detail below.

The book was revolutionary but its initial reception was modest. It was Principles, more than any other single work, that gradually transformed economics into the modern subject. Modern microeconomics — including the parts mainstream economics absorbed and the parts it didn’t — descends from Menger’s framework.

See: Principles of Economics - Carl Menger.

Investigations into the Method of the Social Sciences (1883)

The methodological defense against the German Historical School. Established the Austrian commitment to:

  • Universal economic theory derivable from the logic of human action
  • Methodological individualism (only individuals act, choose, and have purposes)
  • Deductive theory rather than purely empirical pattern-matching
  • The distinction between theoretical economics and economic history

This book is less directly relevant to Bitcoin economics than Principles, but it established the intellectual framework within which Austrian economics could develop independently of the mainstream. Without the Methodenstreit, there might be no recognizable Austrian school today.

On the Origins of Money (1892)

A relatively short essay published in The Economic Journal, but historically important because it presented Menger’s theory of money’s emergence to an English-speaking audience for the first time. The argument was a condensed version of Chapter 8 from Principles, refined and more accessible.

This is the essay that established Menger’s theory of money internationally and that later Bitcoiners (especially Nick Szabo in Shelling Out, Ammous in The Bitcoin Standard, and Boyapati in The Bullish Case for Bitcoin) drew on directly.

See: On the Origins of Money - Carl Menger.

The theory of money’s origin

This is Menger’s single most important contribution. The argument runs roughly as follows.

The puzzle

Before money exists, exchange happens through barter — direct trade of one good for another. But barter has a fundamental problem: the double coincidence of wants. To trade, both parties must want what the other has at the moment of exchange. The farmer with wheat who wants shoes must find a shoemaker who specifically wants wheat — at the right time, in the right quantity, of the right quality.

This is grossly inefficient. Most desired trades never happen because the double coincidence isn’t satisfied. Specialization is limited because traders can’t reliably exchange their output for what they need.

But how does an economy escape barter? No one can simply invent money and expect others to accept it. No government decree can make a worthless object into a medium of exchange. So how does the transition happen?

Menger’s answer

Menger’s solution: money emerges through the gradual recognition by market participants that certain goods are more salable than others, and that holding the most salable goods enables better trading even when those goods aren’t directly desired for consumption.

The argument proceeds in stages:

Stage 1. In a barter economy, traders observe that some goods are easier to trade than others. A cow can be traded relatively easily because many people have uses for cows. A specific custom-made tool might be very valuable to one specific person but nearly worthless to anyone else. The first good has higher salability than the second.

Stage 2. Self-interested traders gradually realize that even if they don’t want a particular highly-salable good themselves, accepting it in trade is rational because they can use it to acquire what they actually want. The trader receives the salable good not to consume it but to re-trade it.

Stage 3. As more traders adopt this strategy, the most salable goods become commonly accepted in trades. They begin functioning as media of exchange, even though no one designed them to be.

Stage 4. Through ongoing market selection, the goods with the highest salability across scales, space, and time win out as media of exchange. Eventually, one or a few goods become universally accepted in trades.

Stage 5. Once a good is universally accepted, it becomes money — performing all the functions of money (medium of exchange, store of value, unit of account) — even though no one set out to create money.

The key insight: spontaneous order

This is what Menger established: money is a spontaneous order. It emerges from the uncoordinated actions of self-interested individuals, none of whom intends to create money. No legislature designs it. No social contract establishes it. No central authority issues it. It emerges, in Adam Ferguson’s famous phrase that Hayek later quoted, as the “result of human action but not of human design.”

This insight is foundational for several reasons:

  1. It refutes chartalist/state theories of money. The state did not create money. Money preceded the state historically and conceptually. State-issued currencies are downstream developments, not the original phenomenon.

  2. It explains why historically, all monies began as commodities. Gold, silver, salt, cattle, beads — these had non-monetary uses before becoming money. That non-monetary value is what kicked off the salability competition.

  3. It provides the foundation for Mises’s regression theorem. Mises took Menger’s insight and made it rigorous: the present value of money traces back through time to a moment when the good had purely commodity value. This solved the circularity problem in monetary theory.

  4. It establishes the framework for analyzing Bitcoin’s emergence. Bitcoin is a contemporary example of money emerging through market selection rather than state design — exactly the process Menger described 150 years ago.

See: Origins of money, Bitcoin as emergent money, Mises and the theory of money.

The Bitcoin connection

Bitcoin’s emergence directly instantiates Menger’s framework:

  • No central designer. Satoshi Nakamoto created the protocol, but Bitcoin’s emergence as money has been a spontaneous market process, not a designed outcome.

  • Salability competition. Bitcoin’s adoption has progressed through recognition by market participants that it has superior monetary properties — high salability across scales, space, and especially time.

  • No state sponsorship. Bitcoin emerged without any government’s involvement. The early adopters had no privileged position. The network grew through voluntary participation.

  • Gradual recognition. Bitcoin’s monetization has followed a Mengerian pattern: from collectible (used by enthusiasts), to store of value (recognized by those seeking inflation hedges), toward medium of exchange (still emerging), toward unit of account (future).

For Mengerians, Bitcoin is not a strange anomaly. It’s the predictable outcome of the same process that gave us gold — but adapted to digital conditions and superior in its monetary properties.

See: Store of value vs medium of exchange vs unit of account, Bitcoin as emergent money.

Salability as a concept

Salability deserves its own treatment because it’s so foundational across the broader Bitcoin material.

What Menger meant

For Menger, salability (Absatzfähigkeit in German) is the degree to which a good can be sold without loss in price. A highly salable good can be sold quickly, at a reliable price, in various quantities, across different locations.

Menger identified several dimensions:

  • Range of buyers. A good with many potential buyers is more salable than one with few.
  • Quantity range. A good that can be sold in many different quantities (small or large) is more salable than one constrained to specific quantities.
  • Spatial range. A good that can be sold across geographic regions is more salable than one limited to a local market.
  • Temporal range. A good that retains value across time is more salable than one that decays rapidly.

A good that scores high across all these dimensions is highly salable. A good that scores high on some but not others has limited salability.

The modern Ammous decomposition

Saifedean Ammous, in The Bitcoin Standard, popularized a clean three-dimensional decomposition:

  • Salability across scales — the good can be divided and aggregated into different sizes
  • Salability across space — the good can be transported across locations
  • Salability across time — the good can be held without loss of value

This framework, while explicitly Mengerian, became the standard analytical tool for Bitcoin-Austrian writers. When you see “salability” used, this three-dimensional decomposition is usually what’s meant.

The critical dimension is salability across time, which Ammous and others identify with hardness or stock-to-flow ratio. This is what separates monetary goods from non-monetary goods and what determines which monetary goods win out over time.

See: Hard money vs fiat money, Stock-to-flow model.

Why Bitcoin wins on salability

Applying the framework to Bitcoin:

  • Salability across scales: Maximal. Bitcoin is divisible to one hundred-millionth (the satoshi). Larger transactions are also straightforward.
  • Salability across space: Maximal. Bitcoin can be transmitted globally in minutes for negligible cost, without intermediaries.
  • Salability across time: Maximal. Bitcoin has a hard supply cap of 21 million. Stock-to-flow surpassed gold’s around 2024 and will continue to harden indefinitely.

By Menger’s own framework, applied rigorously, Bitcoin is the most salable good ever to exist. This is why so many Mengerian-trained economists are bullish on Bitcoin — they’re not abandoning their framework, they’re applying it.

Menger’s broader Austrian inheritance

The full reach of Menger’s influence on the Austrian tradition is hard to overstate. Briefly:

Methodological commitments inherited

  • Subjective value theory — every Austrian holds this
  • Methodological individualism — every Austrian holds this
  • Marginalism — universal in modern economics
  • The hierarchy of goods — extended by Böhm-Bawerk into capital theory
  • Spontaneous order — extended by Hayek into social theory
  • The defense against historicism — extended by Mises into praxeology

Specific doctrines inherited

  • Money’s market origin — extended by Mises in the regression theorem
  • Salability — central to Ammous, Boyapati, modern Bitcoin economics
  • The Methodenstreit position — defines Austrian methodology to this day

The thinkers who built on Menger

Direct intellectual descendants include:

  • Eugen von Böhm-Bawerk (1851–1914) — extended Menger’s value theory into capital and interest. Wrote The Positive Theory of Capital (1889), foundational for Time preference and money.
  • Friedrich von Wieser (1851–1926) — extended Menger’s value theory into price theory and developed concepts like “opportunity cost.”
  • Ludwig von Mises (1881–1973) — second-generation foundational thinker, formalized Menger’s monetary theory in The Theory of Money and Credit (1912).
  • Friedrich Hayek (1899–1992) — extended Menger’s spontaneous-order analysis into social, legal, and political theory.
  • Murray Rothbard (1926–1995) — synthesized the Austrian tradition into a comprehensive system in Man, Economy, and State (1962).

Modern Bitcoin-Austrian thinkers (Ammous, Boyapati, Breedlove, Alden, etc.) work within this Menger-descended tradition even when they don’t cite him explicitly. The categories they use, the questions they ask, the methods they apply — all are Mengerian inheritances.

See: Ludwig von Mises, Murray Rothbard, Friedrich Hayek.

Counter-arguments and tensions

A serious thinker page engages the genuine debates around its subject:

The empirical accuracy of the money-origin story

Some economic historians (notably David Graeber in Debt: The First 5000 Years, 2011) have argued that Menger’s account of money’s origin is historically inaccurate — that money emerged from credit and tax systems rather than from barter. This critique was prominently raised in the 2010s and remains debated.

The Austrian response: Menger’s account is a logical reconstruction of how money can emerge, not a claim that every historical money followed exactly this path. Different paths may have been taken in different cases, but the salability mechanism remains valid as an explanation of how a money can win out once any kind of medium of exchange exists.

Whether or not the historical claim is fully correct, the structural argument about salability is robust. Bitcoin’s emergence in the contemporary digital economy is itself an empirical test of the framework — and Bitcoin has emerged largely as Menger’s framework predicts.

The status of subjective value

Some critics argue that subjective value theory makes economics insufficiently scientific — that without objective measures of value, economic theory becomes untestable. Marxists particularly object to the displacement of the labor theory of value.

Austrian response: subjective value theory is what makes economics actually correspond to how human action works. Pretending values are objective produces worse predictions, not better ones. The displacement of the labor theory of value was a genuine intellectual advance.

Menger and his successors

A genuine internal Austrian question is the relationship between Menger’s framework and later developments. Some thinkers (Joseph Salerno, others) argue that Mises’s praxeological framework diverges from Menger’s more empirical-historical approach. Others argue that the lineage is unbroken.

This is an internal Austrian debate that doesn’t affect the Bitcoin-relevant claims directly. The doctrines you need from Menger — salability, subjective value, methodological individualism, spontaneous emergence of money — are uncontroversial within the Austrian school.

Menger’s monetary policy views

Worth noting: Menger himself was not as radical as later Austrians on monetary policy. He served on government monetary commissions and accepted some role for state currency management. He was not a strict goldbug in the Rothbardian sense, nor an opponent of central banks in principle.

This historical fact is sometimes invoked by Bitcoin critics to argue that “real Menger” was more moderate. The Austrian response: theoretical foundations and policy applications are distinct. Menger’s framework supports the more radical positions developed by Mises and Rothbard even if Menger himself didn’t fully draw those conclusions. The framework is the inheritance, not the specific historical policy positions.

Where to read Menger

For a reader wanting to engage Menger directly:

Essential primary readings

  • Principles of Economics (1871, English translation 1950) — the foundational work. The first 100 pages establish the entire framework. The chapter on money (final chapter) is essential reading.
  • “On the Origins of Money” (1892) — the short essay that established the theory internationally. Highly accessible, ~30 pages. The single best Menger reading for Bitcoin context.

Secondary works on Menger

  • Friedrich Hayek, “Carl Menger” — biographical and intellectual essay, included in some editions of Principles
  • Joseph Salerno, “Carl Menger: The Founder of the Austrian School” (Mises Institute essay)
  • Lawrence White, The Theory of Monetary Institutions (1999) — places Menger in the broader monetary theory tradition

For the Bitcoin connection

  • Nick Szabo, “Shelling Out: The Origins of Money” (2002) — applies Menger’s framework to the prehistoric origins of money, with implications that anticipate Bitcoin
  • Saifedean Ammous, The Bitcoin Standard (2018) — applies Menger and Mises to Bitcoin specifically
  • Vijay Boyapati, The Bullish Case for Bitcoin (2018) — explicitly Mengerian framework applied to Bitcoin

See: Nick Szabo, Saifedean Ammous, Vijay Boyapati.

Open questions in Mengerian Bitcoin economics

Questions worth tracking as this discussion develops:

  • How tightly does Bitcoin actually fit Menger’s salability framework? Where are the imperfect fits, and what do they tell us about how Bitcoin extends or modifies the original theory?
  • Was Graeber right that money emerged from credit and tax systems rather than barter? If so, does this affect how we should think about Bitcoin’s emergence?
  • How should the Mengerian framework treat the role of network effects, which are sharper for digital money than for commodity money? Is salability already a network-effect concept, or does Bitcoin require an extension?
  • What would Menger himself have made of Bitcoin? His later writings suggest more openness to state monetary management than his Austrian successors. Would he have seen Bitcoin as fulfilling his framework or as a curious special case?
  • The “spontaneous order” framing fits Bitcoin’s emergence well, but the protocol itself is intentionally designed. How should we think about a designed protocol becoming spontaneously adopted as money?
