Carl Menger

Before Carl Menger published Grundsätze der Volkswirtschaftslehre in 1871, he wrote market reports for the Wiener Zeitung. His work brought him into contact with everyday price movements. He later became a professor at the University of Vienna. His book marks the beginning of the Austrian school, not the conclusion of all its later debates. When looking for his writings, watch out for a similar name: his son Karl Menger was a mathematician. This is not an alternative spelling for the same author. [1]

Imagine a carpenter who spends weeks making a cabinet that will not fit in a prospective buyer’s home. The effort alone will not persuade the buyer. Menger asks which need a person can meet by having that item and how important that need is to them. This is where the value they place on the item comes from. Quantity matters too: another identical cabinet may not meet a need as urgent as the first. This approach is called subjective value theory. It does not mean we can dictate any market price we like. It means valuation begins with people and their circumstances, not the hours on a production sheet. [2]

Bread satisfies a customer’s hunger. Flour and a baker’s oven do not provide the same service directly, but help produce the bread. Economists call such means of meeting needs goods. Menger distinguishes goods of different orders: an order identifies a good’s place on the path to satisfying a need. A higher order does not mean higher quality. Use matters; fuel can heat a room directly or be used in baking. The inputs must also work together: flour alone, without the other necessary inputs, cannot make bread. We trace the purpose of production back from people’s needs to the means of meeting them. [2]

Try selling barely used furniture today for what you paid. You might find a buyer who wants a discount; waiting longer might bring a better offer. This illustrates the saleability Menger explored in On the Origin of Money in 1892. The question is not merely whether something has value. Quantity, location, time and the price achievable in an exchange matter too. A readily saleable good does not guarantee a sale at whatever price its owner wishes. [3]

In our example, the carpenter wants bread, but the baker does not currently need a cabinet. Direct exchange stalls. The carpenter can nevertheless accept something else that the baker and other traders readily take. He does not need to consume it; he needs it to reach what he wants. This is indirect exchange. Menger describes people learning to use this advantage and copying others’ successful practices. A generally accepted medium of exchange can thus grow out of individual transactions without a prior agreement among everyone involved. [3]

This explanation does not mean Menger denied every role for the state. He distinguished the origin of money from subsequent legal recognition, arrangements for minting coins and checks on their weight or fineness. Fineness means the proportion of precious metal in a coin. He also allowed for a medium of exchange to be established by legislation, while rejecting this as the only or original way money arose. His argument cannot be reduced to saying that anything the state touches ceases to be money. He asks how acceptance spread and what rules changed later. A particular historical case still requires its own evidence. [3]

In Untersuchungen, published in 1883, Menger defended theoretical investigation in a dispute with the German historical school. For a reader, the distinction can be illustrated this way: a price record shows what happened; a theory seeks to explain relationships behind the events we observe. The dispute belongs to its own time. It would be wrong to derive every method later used by other Austrian economists from a single position of Menger’s. Sharing a school’s name does not mean its members wrote the same book. [1]

Carl Menger died in 1921. He never knew Bitcoin and expressed no view on it. Today we can apply his questions ourselves: how is a particular medium useful to people, who accepts it and how readily can it be exchanged again? That is our contemporary interpretation. Neither high production costs nor scarcity alone guarantees demand. His writings offer a way to think about value and exchange, not a historical endorsement of a particular digital asset or a forecast of its future price. [1] [2] [3]
