Can capitalism prosper economically while losing the loyalties that sustain it politically? In this 1943 review essay, Fritz Machlup compares Graham’s proposals to reform free enterprise with Joseph A. Schumpeter’s prediction that capitalism’s success will prepare its replacement by socialism. Their shared commitment to individual freedom sharpens rather than resolves their disagreements over monopoly, inheritance, and the owner-managed firm. Machlup distinguishes the economic case for large corporations from their effects on attachment to private property, and tests institutional proposals against the values they promise to preserve. His scrutiny is especially pointed where Schumpeter moves from explaining capitalism’s decline sociologically to establishing democratic socialism’s logical possibility. The comparison lets readers examine how liberal commitments can support divergent prescriptions—and why efficiency, freedom, and political survival cannot be treated as interchangeable measures.

'Forced saving' had wandered through monetary theory, cycle theory, war finance, socialism, rationing, and corporate boardrooms, collecting incompatible meanings along the way — and this 1943 survey sets out to disentangle them. At its core lies a monetary idea: when bank credit or newly active money finances investment, capital formation can exceed what people meant to save, forced on the community, in Machlup's phrase, through monetary witchcraft. But the real consequences vary wildly, from no added investment under immobility to genuine consumption sacrifice at full employment. Drawing on Robertson's careful separation of money 'lacking' from real deprivation, and on Mises, Schumpeter, and Keynes, he ends with a thirty-four-item taxonomy of synonyms and homonyms, deliberately retiring the ambiguous phrase itself. A term that connotes so many meanings, he concludes, has lost its usefulness.

Saving refers merely to money amounts; lacking, on the other hand, refers to “real” quantities.

First published in 1943 and reissued here, this technical study rebuilds foreign-trade theory around the money-income multiplier, discarding the instantaneous multiplier of textbook exposition for a period-by-period sequence in which time itself becomes a variable. Machlup traces how an autonomous export sets off successive rounds of income and induced imports, then layers in induced saving, foreign repercussions across two and three countries, and the capital account, all through numerical model tables and elementary algebra. Foreign trade, he shows, plays a double role—both multiplicand and determinant of the multiplier—so that imports lagging behind exports are what let income rise at all. He closes by refusing the neo-mercantilist temptation, since the multiplier offers no honest warrant for tariffs and quotas once price effects, retaliation, and the gains from international division of labor are admitted.

Only the lag of imports behind exports makes it possible that money income rises as a consequence of the exports.

Public responsibility need not mean public ownership—and private ownership need not mean private control. This distinction anchors Fritz Machlup’s 1943 examination of how government and enterprise should share economic tasks. He accepts grounds for social insurance, monopoly control, and compensatory public spending, while asking when these remedies weaken incentives or accumulate powers that endanger political liberty. His distinctive concern is not to draw an immutable boundary but to identify what each intervention displaces: alternative uses of resources, private investment, or managerial discretion. Readers can discover why social-security expenditure is not simply a social cost, why a commitment to competition might paradoxically encourage nationalization, and why public investment must fill an economic gap without enlarging it. The result is a conditional framework for judging intervention rather than a blanket case for or against it.

Can competitive price theory be taught convincingly before students encounter monopoly and imperfect competition? In this 1943 review of the preliminary edition of George J. Stigler’s The Theory of Competitive Price, Fritz Machlup weighs that pedagogical choice while testing the precision of definitions, diagrams, and explanations. His detailed corrections coexist with admiration for Stigler’s concise exposition: a demanding textbook can clarify theory without making it easy. The review offers a concrete view of what Machlup expects from economic instruction—analytical distinctions that hold up under scrutiny, assumptions whose purpose students understand, and technical tools connected to actual problems. His closing disagreement with Schumpeter over the book’s level turns on students’ mathematical preparation, leading to an insistence that advanced theory belongs in the undergraduate curriculum.

Can public supervision restrain international cartels, or does it protect them from the competition that might otherwise undermine them? In this published lecture, reprinted in 1946, Fritz Machlup examines how territorial divisions, patent licenses, and output quotas restrict trade without necessarily taking the form of explicit price-fixing agreements. His criticism separates economic harm from personal wrongdoing: a former participant in an Austrian paperboard cartel’s council, he acknowledges that cartelists may sincerely believe they serve the public. The sharper question is what their arrangements do. Readers can discover why stable prices may mean unstable employment, why capacity quotas can encourage further expansion, and why registration or official oversight may legitimize restrictions rather than remove them.

Government control sanctifies the cartel.

Does a restraint on competition become less harmful when governments rather than private firms administer it? In this 1946 conference discussion, Fritz Machlup tests proposed international trade rules against the interests of consumers, whose dispersed losses attract less political attention than producers’ concentrated gains. His example of Bolivian tin makes the stakes concrete: maintaining high prices to preserve inefficient operations can conceal a consumer tax more costly than explicit assistance to displaced workers. He applies a related test to patent licensing, arguing that access to industrial knowledge need not require accepting restrictions on output, sales, or exports. The contribution offers a sharp distinction between helping industries adjust and protecting them from adjustment—and explains why Machlup favors compulsory licensing over either restrictive technology transfers or ineffective prohibitions.

In my judgment, people should know when they are taxed and for what purposes.

Empirical critics of the 1940s claimed that interviews and questionnaires had caught firms behaving in ways marginal analysis could not explain; the reply here is that they had misunderstood the theory they meant to refute. Economic theory, Machlup argues, is essentially a theory of adjustment to change, and its variables are the entrepreneur's own expected costs and revenues, not the observer's accounting magnitudes — a driver overtaking a truck responds to speed and distance without computing them. Reports of 'full-cost' pricing dissolve on inspection: average cost may smooth fluctuations over time, discipline a cartel, or hint at rivals' demand elasticity without contradicting marginalism. He is hardest on Richard Lester's wage-employment surveys, whose 'importance' ratings confuse frequency with marginal effect. The theory has not been disproved, he insists, though better empirical work, grounded in theory, is badly needed.

The business man does what he does on the basis of what he thinks, regardless of whether you agree with him or not.

When Richard Lester marshalled questionnaire evidence to argue that businessmen do not think at the margin, Machlup answered with this compact 1947 reply, reprinted here, that concedes almost nothing. Lester’s executives said employment depends chiefly on sales and orders; Machlup responds that sales expectations were always part of marginal productivity reasoning, not an antimarginalist discovery. He works through Lester’s six conclusions on wage rates, variable costs, factor substitution, and multiprocess plants, insisting that marginal analysis never required rising unit costs and that firms can reckon in incremental rather than average terms. His deeper charge is that Lester mistakes the proximate vocabulary of managers — orders, morale, sales effort — for a refutation of the causal structure economists actually analyze.

Incremental costs and revenues can be known without any knowledge of average costs and revenues; the reverse is not true.

When does economic research justify policy advice, and when do its conclusions outrun its assumptions? In this 1948 review of the National Bureau of Economic Research’s anniversary collection, Fritz Machlup tests the reasoning that connects theory, evidence, and intervention. He challenges Harold G. Moulton’s claims to have displaced obsolete doctrines and questions Jan Tinbergen’s case against exchange-rate adjustment, distinguishing domestic-currency import expenditure from demand for foreign exchange. His praise for John Jewkes’s analysis of British employment policy supplies a contrasting standard: practical experience should sharpen questions about inflation, administrative limits, and the evidence still needed. The review offers a compact encounter with Machlup’s critical method—asking whether a proposition holds generally, under what conditions it holds, and whether those conditions support the policy proposed.

Can the history of an institution establish that it ought to endure? In this review of Harold G. Fox’s Monopolies and Patents, Fritz Machlup challenges the passage from historical origins to permanent justification. Fox’s defense of English monopoly grants rests, Machlup argues, too heavily on benevolent intentions and too little on economic effects. Against the claim that opposition to invention patents is recent, he recalls nineteenth-century controversy and the Dutch repeal of patent law in 1869. Yet he separates these objections from his appreciation of Fox’s detailed documentation. The review offers a compact example of how to distinguish a useful institutional history from the economic claims made on its behalf.

An accounting identity can be correct and still mislead a student about what causes economic change. This is the tension Fritz Machlup pursues in his 1949 review of the first volume of Erich Schneider’s Introduction to Economic Theory. He welcomes Schneider’s effort to build national-income accounts from the bookkeeping of individual firms, but questions formulations that make taxes and budget deficits appear to determine entrepreneurial income merely by definition. His criticism turns on a precise distinction: quantities recorded after the event do not, by themselves, explain how policy changes affect behaviour. The review offers a compact lesson in reading macroeconomic equations critically, while preserving Schneider’s case for aggregation as a practical necessity rather than a substitute for understanding individual decisions.
