Volume 2 extends Rothbard's price theory into a theory of entrepreneurship, money, and intervention. The market appears not as a static mechanism of distribution, but as a procedure of economic calculation under uncertainty: prices, interest, profit, and loss order scarce means by testing expectations and making misallocations visible. The evenly rotating economy serves only as a limiting case that shows what precisely does not disappear in the real economy.
Denn die GRW bedeutet das Verschwinden der Ungewissheit und der Gewinn ist das Ergebnis der Ungewissheit.
English translation: For the ERE [evenly rotating economy] means the disappearance of uncertainty, and profit is the result of uncertainty.
Profit is therefore not an automatic return to capital, but the result of superior foresight; loss shows that factors of production are more urgently demanded elsewhere. Rothbard thereby shifts the analysis away from class or cost categories and toward entrepreneurial appraisal of future consumer wants.
Das Kapital erzeugt keinen Gewinn. Das tun nur kluge unternehmerische Entscheidungen.
English translation: Capital does not generate profit. Only shrewd entrepreneurial decisions do.
Saving, capital formation, and interest are explained from time preference. Lower time preference lengthens production processes, raises capital equipment and real income; dissaving shortens the structure and consumes wealth. Technology alone therefore does not ground progress if enough saved capital is not available. Chapter 9 applies this connection to factor prices, wages, rents, entrepreneurial income, and location decisions: for Rothbard, distribution is not a subsequent social act, but the pricing of productive services within the production process itself.
Monopoly theory forms the conceptual high point of free-market theory. Cartels, mergers, large firms, advertising, brands, and product differentiation do not count as disturbances of competition so long as they rest on voluntary property and contract. Rothbard rejects the concept of a monopoly price because there is no independently determinable competitive price from which the actual price could deviate.
Es gibt nur den »marktwirtschaftlichen Preis«.
English translation: There is only the »free-market price«.
His critique therefore also targets ideals of perfect competition: the diversity of products, locations, and firm forms is not a defect, but an expression of consumer valuations. Union-enforced wages appear not as productive redistribution, but as restrictive prices that benefit some workers and exclude others. Patents are criticized as state monopoly privileges, while copyright is treated as a contractually grounded property right.
Chapter 11 makes money the medium of the entire analysis. Money is a commodity and a general medium of exchange; its price is purchasing power, not a measurable "price level." Rothbard emphasizes the demand to hold cash, defends so-called hoarding, and denies the neutrality of money. An expansion of the money supply creates no social wealth, but shifts purchasing power toward the early recipients of new money. He therefore criticizes quantity formulas, price indexes, and aggregates such as velocity. Fractional-reserve banks create fiduciary media, whereas genuine money certificates would be fully covered warehouse receipts. Business-cycle theory follows from this: systematic forecasting errors do not arise from the free market, but from credit expansion that pushes the interest rate below the rate determined by time preference.
Chapter 12 draws the political consequence. Rothbard presents intervention as the replacement of voluntary actions by coercion.
Eine Intervention ist das Eindringen von aggressiver physischer Gewalt in die Gesellschaft; zu intervenieren bedeutet, freiwillige Handlungen durch Zwang zu ersetzen.
English translation: An intervention is the intrusion of aggressive physical force into society; to intervene means to replace voluntary actions with coercion.
Price ceilings, minimum wages, exchange controls, licenses, and tariffs generate shortages, surpluses, unemployment, or privileges. Taxation and government spending shift resources from producers to politically preferred uses; without genuine capital accounting, public enterprises lose the standard of rational allocation. Rothbard also interprets depressions not as market failure, but as the necessary liquidation of earlier monetary distortions.
The appendices carry this line against public debt, public goods, and external benefits. Rothbard's systematic point lies in joining price theory, monetary theory, and political economy: market order arises from property, contract, and calculation; intervention damages precisely those price signals on whose functioning it tacitly depends.
