Carl Menger (1840–1921) was a celebrated Austrian economist and jurist, universally recognized as the sole founder of the Austrian School of Economics and one of the three pillars of the Marginalist Revolution (along with William Stanley Jevons and Léon Walras) that permanently transformed economic science in the 1870s.
1. Life and Intellectual Trajectory
Carl Menger was born in Neu-Sandez, Galicia (then part of the Austro-Hungarian Empire, now Poland), into a wealthy family of jurists and military officers. Following family tradition, he studied Law at the universities of Prague and Vienna, and later obtained a doctorate in jurisprudence at the University of Cracow.
In the late 1860s, while working as an economic journalist and market editor for the official newspaper Wiener Zeitung in Vienna, Menger made a crucial observation that would change the course of his career: the theoretical explanations of classical economics (Adam Smith, David Ricardo) on how prices were set did not fit at all with the empirical reality of the market. The prices of goods in day-to-day life did not depend on production costs or accumulated labor hours, but on the valuations of actual buyers.
Motivated by this mismatch between theory and practice, he began an independent investigation that culminated in 1871 with the publication of his masterpiece: Principles of Political Economy.
His theoretical brilliance earned him recognition in circles of power. In 1876, he was appointed tutor to Crown Prince Rudolf of Habsburg, son of Emperor Franz Joseph I. Menger accompanied the young archduke on educational trips through Western Europe and delivered lectures on political economy that marked the prince's thinking. Subsequently, he obtained the chair of Political Economy at the University of Vienna, where he taught until his retirement in 1903. Menger spent his last years secluded in his immense library, dying in 1921 in a Vienna devastated by the aftermath of the First World War and the fall of the Empire he loved so much.
2. Work and Fundamental Theoretical Contributions
Menger did not seek to formulate abstract mathematical models, but to understand the causal laws and ultimate foundations of individual action in the market. His key contributions are divided into three areas:
A. Principles of Political Economy (1871) and the Revolution of Value
In this treatise, Menger refounded microeconomics through three interconnected concepts:
-
The Subjective Theory of Value: Menger demolished the classical labor theory of value (also defended by Karl Marx). He argued that value is not an intrinsic property of goods nor is it determined by the cost of producing them. Value is purely subjective: it is born in the mind of the individual, who assigns importance to a good based on the capacity he perceives in it to satisfy a specific need.
-
Marginal Utility: Although the exact term would later be popularized by his disciple Friedrich von Wieser (Grenznutzen), Menger formally resolved the famous "paradox of water and diamonds". He explained that human beings do not evaluate the utility of a good "in general" (for example, the total water on the planet), but decide based on concrete units. The value of a good is determined by the utility provided by the last available unit (the marginal unit), which is used to cover the least urgent need.
-
The Structure and Order of Goods: He classified goods according to their proximity to final consumption:
-
Goods of the first order: Direct consumption goods that satisfy an immediate need (e.g., a piece of bread).
-
Goods of higher orders: Capital or production goods necessary to manufacture those of the first order (e.g., flour is of the second order, wheat of the third order, the plow of the fourth order).
Menger demonstrated a fundamental rule: the value of higher-order goods (factors of production) is derived from the subjective value that the final consumer assigns to the first-order good that they help to produce, and not the other way around.
B. The Evolutionary Origin of Money (1892)
Before Menger, it was commonly believed that money had been created by a governmental decree or a deliberate social contract. Menger offered a purely evolutionary and spontaneous explanation: money emerged organically from barter. Individuals realized that it was very difficult to exchange goods directly (lack of coincidence of wants), so they began to exchange their products for more marketable or liquid goods (such as salt, cattle, gold, or silver). Over time, the market spontaneously selected the most efficient commodities, transforming them into money.
C. Investigations into the Method (1883) and the Methodenstreit
Menger published a methodological book that sparked the famous "Battle of the Methods" (Methodenstreit) against the German Historical School, led by Gustav von Schmoller. While the Germans defended that economics could only be studied by accumulating historical and descriptive local data, Menger firmly defended the validity of the theoretical-deductive method. He coined the principle of methodological individualism, maintaining that macroeconomic or collective phenomena can only be understood if the logical laws governing the decisions of particular individuals are analyzed.
Criticisms and responses to his ideas
Carl Menger's revolutionary ideas burst with such force into late 19th-century Europe that they simultaneously challenged the two great academic blocs of the time: the dominant historical tradition in Germany and the nascent mathematical current in other centers of Europe.
Below are the three main criticisms he faced and how he articulated his responses to defend the birth of the Austrian School of Economics:
1. The Methodological Critique: The Methodenstreit (German Historical School)
This was the most heated and lasting dispute of his life, known as the "Battle of the Methods" (Methodenstreit). The main detractor of Menger was Gustav von Schmoller, leader of the influential German Historical School.
-
The critique: Schmoller and his followers harshly attacked Menger's Principles of Political Economy, arguing that economics did not possess "universal laws" valid for all times and places. From their holistic and nationalist perspective, economic phenomena were strictly subordinated to culture, language, historical institutions, and the particular spirit of each nation. They accused Menger of reviving the "sterile and unreal abstraction" of the British classical economists (like Ricardo), divorced from regional empirical and statistical data.
-
Menger's response: In 1883, Menger published a second treatise focused exclusively on methodology: Investigations into the Method of the Social Sciences. In it, he formally defended methodological individualism. Menger argued that social collectives or macroeconomic aggregates (such as "the nation" or "the State") do not act by themselves, but are the result of the actions and valuations of individual human beings. He maintained that, although economic history compiles empirical data from the past, economic theory has the independent task of discovering fundamental and invariable logical and causal laws that govern scarcity and human action in any civilization.
2. The Formal Critique: The Rejection of Mathematics (Neoclassical Marginalists)
Although Menger shares with William Stanley Jevons and Léon Walras the title of father of the Marginalist Revolution, his methods were radically different.
-
The critique: Economists from the mathematical and neoclassical tradition criticized Menger because his theories lacked equations, algebraic formulas, or differential calculus. They considered that his purely logical and qualitative approach was an "imperfect" or imprecise version of microeconomics and that it did not achieve the scientific rigor of the general equilibrium models that Walras was designing.
-
Menger's response: Menger deliberately rejected mathematical formalism in a conscious manner. He argued that the real market is never in a situation of "perfect static equilibrium" as mathematics attempted to simulate. On the contrary, the market is always in dynamic disequilibrium. For Menger, the use of mathematics committed the grave error of assuming that the human being is an omniscient and perfectly rational homo oeconomicus. In Mengerian reality, the human being acts immersed in uncertainty, the passage of time, and imperfect knowledge, constantly making mistakes. He maintained that symmetrical equations hid the true essence of economics, which requires an analysis of unidirectional causal relationships: value is born from the human subject and moves towards things, a qualitative and subjective process impossible to encapsulate in continuous numerical functions.
3. The Ideological and Political Critique: Defenders of Labor-Value (Socialists and Marxists)
The emergence of the subjective theory of value clashed head-on with the collectivist theories that were gaining immense political ground in the late 19th century.
-
The critique: Socialist thinkers and followers of classical economic theory defended that the value of things should be measured in an "objective" way through the production costs incurred or the physically accumulated labor hours in the good. They considered that Menger's radical subjectivism was a "bourgeois psychological theory" designed to delegitimize workers' claims to the full fruit of their labor and to defend the profits of capitalists.
-
Menger's response: Menger destroyed the logical basis of this critique by demonstrating that value does not travel from the past to the present, but from the future to the present. He explained that an entrepreneur can spend millions of hours of labor and resources producing a good (higher-order goods), but if in the end consumers do not desire it (first-order goods), said product will be worth absolutely zero. The cost of production is not the creator of value; on the contrary, it is the subjective valuations that consumers estimate for the future final good that determine how much value is assigned to the machinery, land, and labor necessary to produce it. With this, Menger scientifically armored the free market against theories of exploitation and central planning.
Menger's Legacy
Carl Menger's legacy is the foundation upon which all modern libertarian and free-market thought has been built:
-
Seed of the Austrian School: Although Menger wrote his works in isolation, his chair at Vienna attracted brilliant minds. He directly trained the "second generation" of the Austrian School, headed by Eugen Böhm-Bawerk and Friedrich von Wieser. They, in turn, were the teachers of figures of the third and fourth generation such as Ludwig von Mises and Nobel laureate Friedrich A. Hayek.
-
Precursor of Spontaneous Order: His analysis of the origin of money served as a fundamental model for later thinkers (especially Hayek) to develop the theory of spontaneous social institutions. Menger demonstrated that the most complex and functional structures of human civilization —such as money, language, law, and the market itself— do not require a central planner or a government to design them; they emerge organically from the voluntary interactions of millions of people.
-
Scientific Defense of the Free Market: Menger did not defend the free market based on political slogans or abstract dogmas, but by reconstructing economic theory from its purest human foundations. By placing the human being, his needs, and his knowledge at the epicenter of the economy, he armored the logic of individual freedom against the attacks of the collectivism of his time.
