Making money costly to hold might encourage spending—but could it also shrink the money supply? In this brief 1938 review of A. Dahlberg’s When Capital Goes on Strike, G. L. S. Shackle examines a proposal to tax bank balances and depreciate notes. His distinctive interpretation is that the scheme would make liquidity expensive for money holders while making borrowing cheap. Yet attempts to escape the tax through debt repayment or purchases of banks’ securities could reduce the quantity of money. Sympathetic to further investigation, Shackle nevertheless asks whether a steady incentive can withstand a slump’s self-reinforcing momentum. The review offers a compact distinction between changing the rewards for holding money and adjusting policy to an approaching downturn.

Painstaking exposition can still miss what holds a theory together. In this 1939 review of R. J. Saulnier’s comparative study of Hawtrey, Robertson, Hayek, and Keynes, G. L. S. Shackle praises scholarly fairness while identifying that precise failure in the treatment of Keynes. For Shackle, the General Theory turns on decisions made in almost complete ignorance of the future—not merely on its individual concepts and analytical devices. His brief assessment also questions Saulnier’s reliance on an earlier formulation of Hayek’s theory and distinguishes criticism of the multiplier’s presentation from refutation of its substance. The review offers a compact encounter with Shackle’s interpretive priorities: attention to uncertainty, to the development of an economist’s thought, and to the difference between explaining a theory’s parts and grasping its unity.

Why might an entrepreneur postpone an apparently profitable investment—and why might a boom itself create reasons to stop investing? In this 1939 article, G. L. S. Shackle distinguishes the outcomes entrepreneurs envisage from the clearness with which they envisage them. A ship or steel plant commits resources that cannot remain available for a better-informed choice later; waiting can therefore reflect an expectation of improved knowledge rather than simple pessimism. Extending Keynes’s account of equipment valuation, Shackle tentatively argues that rapid investment changes a business enough to make its future less intelligible. Readers can trace how expansion may generate its own pauses, and how subjective uncertainty can affect investment and employment without being reduced to calculable probability.

It is the belief that knowledge, insight, and foresight will improve that causes the so-called apathy.

A programme for full employment can be sound in principle yet act too late. In this 1939 review of H. S. Dennison and collaborators’ Toward Full Employment, G. L. S. Shackle welcomes their proposals while testing the assumptions that would make them effective. Why wait for unemployment to rise visibly before launching public works? What if prosperity fails to repay the debt incurred during a slump? His sharpest monetary objection follows borrowed money beyond its first use: the economic consequences depend on successive recipients, not simply on the original loan’s purpose. This short review offers a concrete encounter with Shackle’s policy judgement—sympathetic to measures supporting effective demand, but alert to timing, uncertain fiscal outcomes, and the limits of credit classifications.

Preventing depression without making economic security depend on compulsory controls is the tension at the centre of Shackle’s 1947 review of William J. Fellner’s Monetary Policies and Full Employment. Shackle examines Fellner’s distinction between timely action against recession and an unconditional employment guarantee that could encourage inflationary wage and price demands. His particular interest lies in uncertainty: larger expected profits need not be more dependable, and lower wages need not improve investment prospects. This compact review lets readers see why the composition and reliability of demand matter alongside its volume. Shackle’s approval remains discriminating: he praises Fellner’s practical judgement while challenging an interest-rate analysis that, in his view, confuses planned and realised quantities, stocks and flows.

Statistical agreement does not necessarily tell us which economic relationship has been measured. In this 1951 review of Lawrence R. Klein’s Economic Fluctuations in the United States, 1921–1941, G. L. S. Shackle pairs enthusiasm for econometrics with a precise account of its limits. He values its power to expose ambiguities in theory and distinguish consequential relationships from negligible ones, yet shows how a simple consumption–investment model can produce two apparently similar equations with different underlying parameters. His perspective is neither a defence of purely deductive economics nor an unqualified endorsement of empirical modelling: internal coherence is not evidence, but estimation does not guarantee structural knowledge. This short review makes the identification problem accessible while revealing why Shackle found Klein’s methodological candour as valuable as his technical achievement.

Joan Robinson appears in Shackle’s 1953 review as both an iconoclast and a pillar of Cambridge orthodoxy. That tension gives his appraisal its focus: intellectual independence need not mean abandoning the traditions that make it possible. He admires Robinson’s insistence on conceptual clarity, yet asks whether her technical ingenuity sometimes makes economics difficult for the wrong reasons. Her treatment of hoarding offers a contrasting model of clarification useful to students, journalists and legislators alike. His reservations extend to political essays whose moral contrasts he finds too stark. This short review lets readers encounter Shackle’s standards of economic argument through a judgement that distinguishes theoretical achievement from the difficulties of exposition and polemic.

In this brief reply to Gould, Shackle offers an endorsement rather than a counterargument: he praises Gould’s reasoning and supports the directions of inquiry proposed. Its interest lies in the research priority Shackle states with unusual directness—decision-making as perhaps the richest and most central problem in the human sciences. The note records that commitment and agreement without elaborating a theory or specifying the methods by which inquiry should proceed.

When do long odds make an outcome seem not merely improbable but impossible? In this brief reply to Gould, Shackle acknowledges a difficulty for his account of decision under uncertainty: even someone facing a unique venture may let probabilities shape judgements of what can happen. He welcomes investigation of Gould’s proposed modification while insisting on a prior question—whether the conflicting evidence from which businesspeople form expectations can be expressed as numerical odds at all. The exchange offers a compact view of Shackle responding to criticism without abandoning his central distinction between probability and possibility, and helps readers separate two sources of uncertainty: the rarity of a decision and the difficulty of interpreting its evidence.
