"Profit and loss are the instruments by which consumers direct production." — Ludwig von Mises, Human Action, Ch. XIII (paraphrased for length)

Chapter XIII — Monetary Calculation as a Tool of Action

What Mises argues

Monetary calculation is more than a way of comparing present prices; it is the instrument of capital accounting and of profit-and-loss reckoning across time. The entrepreneur casts the money value of the factors he commits (his capital) against the money value he expects the product to fetch (his proceeds). The difference — profit or loss — is the verdict of the market. Profit says: you moved resources from lower-valued to higher-valued uses in the eyes of consumers. Loss says the opposite.

This makes monetary calculation the steering mechanism of the entire market order. It is forward-looking (guiding decisions about what to produce) and backward-looking (auditing whether past decisions served consumers). Capital itself, Mises stresses, is not a physical thing but a calculational concept — the money value assigned to a complex of production goods within a scheme of accounting.

The lineage

Mises' own synthesis, and the foundation of his later demonstration that socialism cannot calculate (Ch. XXVI).

The Framework's Reading

The Framework affirms this as one of the great insights in economics: profit and loss are consumer sovereignty rendered in numbers. And it adds the corrosion warning that runs through the whole series. Because capital is a money-value concept, calculation in a depreciating unit systematically overstates profit and understates the erosion of capital — a firm can report gains while its real capital is being consumed. Fekete built much of his applied work on exactly this: the silent decapitalization that monetary calculation in an unsound unit conceals. Chapter XIII is correct; it is also only as trustworthy as the money it counts in.
