Where the theory was built, this second volume turns to the evidence — prices, output, employment, commodity markets, deposits, loans, and interest — reading every series as the trace of an evolutionary mechanism rather than a barometer that speaks for itself. Schumpeter's method is deliberately anti-barometric: no single index reveals the cycle's true shape, and the Kondratieff–Juglar–Kitchin schema must be used historically, never mechanically. The financial chapters refuse to crown interest as the master cause: it saturates capitalist calculation yet is fundamentally consequential, causal only in a secondary sense, and entrepreneurial demand for credit moves rates before rates move anything. He dissolves the rigid money-market/capital-market divide, denies any secular law of declining interest, and rejects the Hayek–Mises–Hawtrey claim that bank-initiated cheap money originates the cycle.

In this sense interest may indeed be said to hold a central position in the system.

American tariff policy cannot be read off a welfare diagram, this 1940 address insists: protection in the United States preceded the republic itself and grew inseparable from the young nation's drive to make its independence economically real, in a world still organized by empire and war. Schumpeter treats the tariff as a historical institution rather than a technical deviation from free trade, and presents America as an unusually strong case for the Hamilton–List infant-industry argument — a continental market and natural wealth muting protection's usual distortions while it hastened industries likely to arise anyway. He concedes the standing objections, and the high-cost dependents such as wool and sugar, yet concludes that in a mercantilist, conflict-prone world protection's value as a shield for an established industrial order remains as strong as ever.

Protection—or non-intercourse acts and so on—then was simply the economic complement of political independence or of the will to buttress that independence.

Would Marshall's message fade like Mill's or Smith's? This semi-centennial appraisal, read here in G. Bombach's German translation, answers with a deliberate doubleness: Marshall's specific tools, methods, and results are no longer ours — obsolete much as older physics was superseded — yet his influence endures because he built research instruments rather than a closed system. Schumpeter reconstructs the originality behind the Principles: partial equilibrium chosen over Walrasian generality, and the apparatus of elasticity, quasi-rent, consumer surplus, internal and external economies, and the representative firm. He argues that Marshall understated his own debt to mathematics, traces his paternity of imperfect-competition theory through Sraffa and Joan Robinson, and credits him with designing an economics open enough to be revised — and measured — by the discipline that followed.

Seine Vorstellung vom Wirtschaftsablauf, seine Methoden und seine Ergebnisse sind nicht mehr die unsrigen.

English translation: “His conception of the economic process, his methods, and his results are no longer ours.”

'I am not running a drug store,' Schumpeter told the Economic Club of Detroit in the spring of 1941 — no pills to hand out, only a diagnosis. Wartime defense spending, he warned, could be the catalyst that turned America's excess reserves and government-monopolized gold stock into inflation, no greenbacks required. The deeper argument is constitutional: gold was never essential to money, but like Supreme Courts and constitutions it restrained the freedom of action of government, telling the truth, like a naughty child, about a nation's finances. Planned economies resent exactly that discipline, so gold's old function is gone — though he allows it a narrower postwar life within an Anglo-American convention or bullion standard, if governments will accept limits on their own sovereignty.

Gold has no function, for planned economy has come to stay.

Victory, not defeat, is the premise of this 1943 prognosis, which asks not whether capitalism deserves approval but what order can survive the war — defining capitalism by private ownership, private profit and loss, and privately created means of payment, then denying that any social system is ever pure. Total war, Schumpeter argues, builds bureaucracies and vested interests that outlast the emergency, while capitalism's own success corrodes its foundations: large-scale enterprise displaces the owner-manager, routinizes the entrepreneur, and breeds the taxation, labor power, and intellectual hostility that turn against it. He rejects the vanishing-investment-opportunity thesis in favor of this self-undermining account, and forecasts not doctrinaire socialism but an amphibial order — a formally private economy sustained by public expenditure, then Guided Capitalism and State Capitalism — cumbersome, mixed, and less vigorous than capitalism at its height.

But it is capitalism in the oxygen tent—kept alive by artificial devices and paralyzed in all those functions that produced the successes of the past.

Economists dismiss pre-eighteenth-century thought as pre-scientific; historians lack the tools to spot economic theory buried in older texts. Against that double neglect, Schumpeter praises Father Dempsey's study of interest and usury for reading late-scholastic theology from within while judging it by modern standards. The Jesuits Molina, Lessius, and de Lugo, he argues, worked in a world already full of money markets, speculation, and negotiable paper, and their empirical method did not differ in logical character from ours. The essay's conceptual center is a sharp separation: economic analysis is valid or invalid autonomously, whatever moral use its results are later put to. From this Schumpeter defends both the scientific seriousness of scholastic inquiry and his warning that modern clergy pronouncing on money and banking must first master the technical economics involved.

Interest holds so central a position in the capitalist organism that it intrudes in practically every economic consideration or valuation.

Written weeks after Keynes's death, this memoir refuses to separate the theory from the man who made it: a Cambridge and Eton mind, mathematically gifted yet impatient with technique that did not bear on public action. Schumpeter reads the whole career as the slow forging of a single vision, first glimpsed in The Economic Consequences of the Peace, that laissez-faire capitalism had ended in 1914 and that thrift no longer served accumulation. The General Theory supplies that vision its machinery, reducing the economy to three schedules: the consumption function, the marginal efficiency of capital, and liquidity preference. Admiring the elegance yet insisting on the narrowness, Schumpeter accepts Hicks's verdict that this is the economics of depression, and grants Keynes a genuine school rivaling the Physiocrats and Marxists.

It does not make us Keynesians, it makes us better economists.

Take a single stretch of history and use it to test what economic analysis can and cannot do: that is Schumpeter's method here, applied to the American 1920s and the collapse that followed. He rejects both the reduction of the decade to monetary quantities and the treatment of it as self-contained, reading its prosperity instead as the American surface of a longer industrial transformation, automobiles, electrical utilities, corporate finance, whose effects were expansive and depressive at once. Prosperity was real but spotty, concealing falling farm and profit tendencies beneath rising output. On the crash he distinguishes why depression was likely from why it turned catastrophic, laying the disaster to speculation in 1927-29, a fragmented banking system prone to epidemics, and a mortgage crisis that turned price declines into panic.

Time series never tell the whole tale and must be supplemented by a detailed historical account of what actually happened in the economic organism.

Historical outcomes, Schumpeter insists, are never explained by naming conditions such as population, capital, or tariffs, since the same factor acts differently through the mechanisms by which an economy answers it. His governing distinction separates the adaptive response, adjustment within existing practice, from the creative response, action outside that range that reshapes the path irreversibly. The agent is the entrepreneur, defined by function rather than social station: not necessarily capitalist, owner, or inventor, but whoever gets a new thing done. Through the example of producing caviar from sawdust he isolates entrepreneurial profit as a temporary surplus erased by imitation, and argues that innovation destroys old capital rather than reallocating it smoothly. A closing inquiry, whether routine, research teams, and bureaucracy will dissolve the entrepreneurial function as capitalism matures, turns the analysis toward the durability of bourgeois civilization itself.

The competition of the man with a significantly lower cost curve is, in fact, the really effective competition that in the end revolutionizes the industry.

Provisional notes rather than a finished theory, this essay asks how economists and historians should define, measure, and explain long-run change without turning theory into metaphysics. For Schumpeter theory is only an empirical toolbox: growth itself has no all-purpose measure, and he adopts the rise of trend per capita output merely as a working definition. His three theses cut against reductionism, that growth cannot be isolated from politics, institutions, and habit, that no single factor explains it, and that it interacts reciprocally with its supposed causes, while he rejects Marxist determinism outright. Naming a factor like war or the sixteenth-century Spanish precious-metal inflation is worthless, he argues, until its mechanism is specified. Against the automatism of the Smith-Mill-Marshall tradition he sets the creative response and entrepreneurship, the recombination of resources that no prior condition can predict.

Economic growth is not an autonomous phenomenon, that is to say, it is not a phenomenon that can be satisfactorily analyzed in purely economic terms alone.

The mechanics of inflation are not obscure; what defeats every cure is the refusal of the groups who count politically to pay the price of stopping it. Reading the American inflation of 1948 through the post-1918 collapses of Austria, Germany, Italy, and France, Schumpeter defines inflation as means of payment rising faster than output and divides the disease into three stages: incipient, advanced, and wild. America, he judges, has reached the advanced phase, where full employment turns new money into general price increases and bank lending breeds secondary credit inflation, the national payroll serving as its chief conductor. His program rejects price rollbacks and direct controls in favor of credit restriction, budget surpluses, and taxes that reward saving, warning with a nod to Lenin that a debauched currency corrodes the very classes on which the social order rests.

So inflation runs on by common consent.

These are not the famous treatise but dense student notes from a 1949 Institute of World Affairs lecture, circulated by Arthur Smithies as the fullest exposition he knew of Schumpeter's late thought. Against Trotsky's claim that imperialism is capitalism's last stage, Schumpeter advances laborism: a society, exemplified by Britain, where labor's interests become the state's governing purpose. Higher wages, shorter hours, subsidies, and cheap money redirect the fiscal state away from capital renewal and defense toward present labor consumption. His feudal analogy is deliberately provocative, since modern redistribution does not abolish the class use of the state but inverts it. A laborist Britain, he predicts, cannot sustain great-power burdens and grows dependent on America, while a dictatorial Russia mobilizes for power politics Britain cannot match.

The working class has replaced Mme. du Barry, and we have the inverse of the feudal system.
