Rothbard’s chapter is a synthetic and polemical reconstruction of Mises’s monetary theory as the specifically Austrian alternative to price-level aggregation, monetary neutrality, and state-managed currency. Its organizing claim is that Mises brought money back inside general economic theory by explaining it through individual action, marginal utility, and historically unfolding market exchange.
The Austrian theory of money virtually begins and ends with Ludwig von Mises’s monumental Theory of Money and Credit, published in 1912.
Rothbard begins by redefining the demand for money as a demand to hold cash balances. Money is not wanted for direct consumption but for its exchange function, and its purchasing power is therefore governed by individuals’ preferences between holding money and acquiring other goods. This makes monetary theory continuous with ordinary price theory, but without reducing money to a measurable aggregate “price level.”
The relative utilities of money units as against other goods determine each person’s demand for cash balances, that is, how much of his income or wealth he will keep in cash balances as against how much he will spend.
The anti-aggregative argument is central. Since money exchanges against heterogeneous goods, its purchasing power is an array of concrete exchange ratios rather than a single magnitude. Rothbard uses this point to reject index-number thinking and the neoclassical habit of separating money from relative prices. Monetary change is never a neutral adjustment of a general level.
Every good and service will have an almost infinite array of prices in terms of every other good and service.
Inflation, accordingly, is a causal sequence in time. New money does not enter all accounts simultaneously or alter all demands proportionally. It reaches particular persons first, changes their purchases, raises some prices before others, and redistributes wealth toward early receivers. Even in highly artificial cases of equal monetary increase, Rothbard argues, different value scales prevent a uniform proportional rise in all prices.
Gradually, the new money ripples through the economy, raising demand and prices as it goes.
From this foundation Rothbard extends the Austrian analysis to international exchange and purchasing-power parity. Goods are economically defined by usefulness in concrete circumstances, not by physical sameness alone; wheat in one location is not necessarily the same economic good as wheat elsewhere. Purchasing-power comparisons are meaningful only for specific comparable goods, not for national price-level aggregates.
The chapter’s theoretical center is Mises’s regression theorem. Rothbard presents it as the solution to the apparent circularity that money is demanded because it already has purchasing power, while purchasing power itself must be explained. Mises’s answer is temporal: today’s demand for money refers back to yesterday’s purchasing power, and the chain regresses to the final day before monetary exchange, when the money commodity was valued for direct use. Thus Menger’s account of money’s market origin is not merely historical but logically required.
Rothbard also uses monetary theory to criticize Walrasian equilibrium. A world of perfect foresight and simultaneous mutual determination cannot explain why actors would hold money at all. Cash balances exist because the future is uncertain and action occurs through time. Monetary theory must therefore be causal and process-oriented, not a system of timeless equations.
The political conclusion follows from Rothbard’s distinction between money and ordinary goods. More consumer or capital goods increase wealth; more money merely changes purchasing power and reallocates command over resources. Government monopoly over money and bank credit expansion are therefore treated as institutionalized redistribution, not as neutral policy tools. Rothbard’s sympathy for gold rests on this institutional argument: commodity money limits discretionary creation by political authorities.
The chapter ends less as a closed system than as an Austrian research program. Rothbard identifies remaining disputes over return to gold, free banking, 100-percent reserves, and the definition of the money supply. Its lasting significance lies in presenting money as an institution emerging from exchange, valued through historical purchasing power, and distorted when abstracted into aggregates or monopolized by the state.
