Epistemics & Economics

[Front Matter and Acknowledgements]: Front matter for G.L.S. Shackle's 'Epistemics & Economics', including the title page, dedication to J.L. Ford, and acknowledgements. Shackle traces the origins of his work to his involvement with Keynesian and Hayekian monetary theories, highlighting the influence of Hayek's study on knowledge and Lachmann's work on the same theme. [Table of Contents]: Detailed table of contents outlining the six books of the work. The structure moves from the formal imagination and the rise of the rational ideal to its dissolution through expectation and uncertainty, concluding with a contrast between epistemics and axiomatics. [Preface: The Human Predicament and the Limits of Reason]: The preface introduces the central conflict between Reason and Imagination in economic theory. Shackle argues that while economics has traditionally relied on the 'rational ideal' by assuming perfect knowledge, the reality of time and the 'unborn tomorrow' necessitates a shift toward epistemics—the study of how humans act under the eternal denial of knowledge about the future. He cites Ludwig Lachmann on the impossibility of prediction due to the link between economic change and unpredictable changes in knowledge. [The Dissolution of the Rational System and the Nature of Time]: This segment explores the transition from the 19th-century conception of Rational General Equilibrium to a modern understanding of economics that incorporates time and expectation. It argues that the rational ideal, championed by Marshall, was essentially timeless and collapsed when the nature of money and the 'Economics of Fallible Expectation' were introduced by Wicksell, Keynes, Hayek, and Myrdal. The author highlights the distinction between the time of celestial mechanics (a mere dimension) and the time of experience (the solitary present), emphasizing that expectation is an undetermined origination rather than a predictable calculation. [A Critique of Keynesian and Hayekian Theory]: The author critiques the works of Hayek and Keynes, focusing on how they subverted the traditional Theory of Value. Hayek's 'Prices and Production' is noted for its lack of an explicit time-lag framework, while Keynes's 'General Theory' is described as a destructive subversion of received theory that relegated the Theory of Value to irrelevance. The segment analyzes Keynes's explanations for involuntary unemployment and his technical innovation of the liquidity-preference theory of interest, which attributes interest to uncertainty and speculative motives rather than a simple balance of impatience and profit. [The Conflict Between Rationality and Time]: This segment addresses the fundamental conflict between the appeal to rationality and the reality of time. The author argues that theoreticians must choose between rejecting time (as in subjective marginalism) or de-naturing it into an artificial space. Marshall is cited as attempting a compromise through a relaxation of rigour. The author proposes an 'expectational system' where success is measured by a 'good state of mind' (ex ante) rather than objective fulfillment. Profit is redefined as a 'counter-expected' outcome that signals the need for fresh thought, leading to the conclusion that economics is a branch of 'epistemics'—the theory of thoughts. [Book I: Economic Theory and the Formal Imagination]: Chapter I of Book I examines how economic theory was shaped by analogies from the physical sciences, leading to the neglect of un-knowledge and novelty. The author argues that the future is non-existent until decisions are made, and thus cannot be known; it is instead imagined. The neo-classical conception of general equilibrium is criticized for assuming a self-contained field of economic events shut off from the rest of human affairs by a wall of rationality. The author asserts that economics is concerned with thoughts and deeds, not the ultimate chemistry of man. [The Interconnectedness of Human Affairs]: The author argues that the world of economic phenomena is not self-contained but is radically affected by politics, diplomacy, and other aspects of human conduct. Political and economic motives are often indistinguishable, both being concerned with acquisition and survival. The segment challenges the idea that economics can answer its own questions in isolation, suggesting that predictions treating economic affairs as autonomous are foolish. It emphasizes that the boundary between business, politics, and art is arbitrary and that all are part of a unified human phenomenon. [Stereotypes, Mathematics, and the Limits of Economic Models]: This segment discusses the role of recognizable patterns or 'stereotypes' in building knowledge and the use of mathematical vectors and functions to express them. The author warns that if economics is not a self-sufficient science, its observed variables may not compose stable stereotypes. A specific critique is leveled at the methodology of accountancy, which relies on a law of conservation that is disrupted by the 'unaccountable shifts of the expectational kaleidoscope.' Valuation is defined as an act of imagination and expectation, which is inherently mutable and private, contrasting with the accountant's need for definite, objective numbers. [The Art of Economic Simplification and the Theory of Money]: The author describes economics as the 'art of reducing incommensurables to common terms' through market prices and scalar quantities. This simplification is critiqued using the theory of money as an example. The 'hydraulic' Quantity Theory of Money is contrasted with a modern view where money's value lies in its possession as a hedge against uncertainty. The Multiplier theorem is discussed as a mechanical device that often ignores the role of anticipatory thoughts. The segment concludes that the rate of interest is the key to the modern conception of money, resting on speculation and the present valuation of future revenues. [Probability, Uncertainty, and the Logic of Choice]: This segment analyzes the two meanings of probability: as a measurement of frequency (knowledge) and as a language for expressing personal judgments (admission of ignorance). The author argues that statistical probability is inapplicable to unique decisions under uncertainty. Subjective probability is critiqued for assuming an 'omni-competent' list of outcomes, whereas the businessman actually faces an endless 'Pandora’s box' of possibilities. The author suggests replacing distributional probability with a 'non-distributional uncertainty variable' that expresses degrees of doubt or possibility rather than fractional belief. [The Borrowed Postures of Economics and the Theory of Games]: The author observes that economics late in its development borrowed tools from physics and engineering, which imposed a false sense of certainty and rationality. Massive unemployment is cited as a disorder that cannot be understood through these orderly models. The Theory of Games is presented as a paradox: while it attempts to treat business as warfare, it grants contestants perfect knowledge of 'pay-offs,' thereby eliminating the element of surprise which is essential to real conflict. The author calls for the discipline to recognize the defects of its inherited tools and explore other modes of understanding the economic scene. [Time, Novelty, and the Limits of Reason]: This segment explores the tension between reason and time. Reason requires complete premises, but time endlessly proposes novelty and unthought-of suggestions that change the meaning of existing systems. The author argues that mathematical models cannot encompass history because they turn their back on fundamental novelty. Time is seen as a denial of the omnipotence of reason, dividing the world into what we can reason about and what we cannot, yet the latter constantly influences the former. The analyst is forced to treat time as an 'artefact' or a space to make it amenable to logic. [Self-Subsistent vs. Non-Self-Subsistent Sciences]: The author distinguishes between self-subsistent sciences (like kinematics or pure mathematics) and non-self-sufficient sciences (like economics). While natural sciences seek a 'Single Secret of Nature' (the hedgehog's one big thing), the study of human affairs requires knowing 'many things' (the fox's approach) and is better served by taxonomic or classificatory methods. The author argues that economics, by attempting to be an axiomatic, self-sufficient science, cuts itself off from the essential, un-abstracted richness of human history and conduct. The segment critiques the reliance on mechanism and equation-systems in a field that is fundamentally non-homogeneous. [Valuation, Variety and Scalar Quantity]: This segment examines how economics reduces the 'limitless diversity' of the business world into scalar quantities through market valuation. The author argues that while technology is the primary concern of the businessman, economic theory sweeps these details into broad aggregates like income and investment. The 'theory of production' is critiqued as being less about the arts of making things and more about the determinacy of marginal exchange values. The author highlights the dangers of this scalarization, particularly in capital theory, where changes in interest rates can distort valuations without any underlying physical change. Economics is defined as the 'art of reducing incommensurables to common terms.' [Formal Codes and their Efficiency]: The author defines 'formal codes' as systems of terms and operations used to simplify complex phenomena. Economic theories are divided into 'analytic' (describing states of affairs like equilibrium) and 'constructive' (describing transformations like the business cycle). Analytic theories are praised for their efficiency but criticized for assuming away the problem of how knowledge is attained. Constructive theories, particularly those using time-lags or difference equations, are examined for their mechanical view of human behavior. The author suggests that a truly insightful theory must account for the self-transforming nature of expectations and the 'kaleidic' process of new situations emerging. [Orientations and the Kaleidic Society]: This segment critiques the use of exact metrical models in economics, arguing that human conduct is originative and inconsistent. The author introduces the concept of 'orientation'—a scheme to exploit the economic scene—and notes that multiple, inconsistent orientations can exist simultaneously. The 'kaleidic society' is proposed as a model where intervals of stability are interspersed with sudden disintegrations and shifts to new patterns. This approach acknowledges indeterminism and the role of 'the news' in shifting expectations. The speculative market is described as inherently restless, poised on conflicting conjectures rather than reconciled needs. [Reason versus Knowledge]: The author examines economics as the 'pure logic of choice,' emphasizing the requirement of self-consistency in action. However, this logic is limited by the assumption of a single maximand and, more critically, by the problem of knowledge. Rational conduct requires full information, which is logically impossible in a world of time where the future is unknown. Value theory is seen as applicable only to an abstract, timeless system. The segment concludes that the pursuit of the rational ideal in the Victorian era led to a narrow circumscription of the field, ignoring that the governance of affairs is exerted through thoughts and interpretations, not just direct circumstance. [Book II: The Construct of Reason]: Book II analyzes the 'Construct of Reason' in economic theory, specifically the equilibrium method. The author argues that rationality depends on synchronicity—the pre-reconciliation of choices in a timeless system. The segment critiques 'particular equilibrium' and the 'ceteris paribus' method for desiccating real-world problems of knowledge. It also explores the limits of reason in situations like duopoly (Cournot) and bargaining (Edgeworth's contract curve), where logic alone cannot determine a unique outcome. The author concludes that equilibrium theory is a non-arbitrary abstraction that achieves beauty at the cost of ignoring the flow of time and novelty. [Subjective Marginalism and the End of the Road]: This segment discusses how subjective marginalism and the differential calculus brought economic theory to a 'terminus' of perfection by conferring determinacy on general equilibrium. The author argues that this system rests on a 'tripod' of pre-reconciliation, diminishing marginal rates of substitution, and the negligible influence of the individual firm. While aesthetically satisfying and unified, this construct cannot accommodate time, which is alien to its logic. The author notes that the 'stationary state' and 'capital theory' are merely artefacts used to mask the rejection of actual, experienced time in neo-classical theory. [The Concept of Value and its Limitations]: The author critiques the concept of 'value' as an instrumental token used to mechanize and determinize conduct. Value is seen as a shadow cast by conduct, not an intrinsic quality. The segment discusses the limitations of using market values for aggregation, the particularity of Marshallian consumer's surplus, and the dependence of value on expectation and speculation. The author argues that price stability in reality is often a matter of convention rather than rational determination. The segment concludes that 'value' is a mutable child of circumstance and that the term itself may disguise the true complexity of political economy. [Quantity versus Form in Economic Theory]: This segment contrasts the economist's focus on quantity ('How much?') with the businessman's focus on form and technology ('How?'). The author argues that by reducing business to scalar quantities and exchange-values, economics ignores the essential 'architecture' of production. While this simplification allows for a general science, it makes economic advice crude. The author suggests that economics could have taken a taxonomic path, focusing on the physical and spatial configurations of industry. The segment concludes that theory is an illuminant that defines profiles but should not be mistaken for the total reality of business and politics. [The Rational Ideal as the Core of Economic Theory]: The author examines the claim that the rational ideal is the core of economic theory. Value theory is seen as a triumph of logic that proves the possibility of rational conduct in a timeless system. However, the author argues that in the real 'Scheme of Things,' choice is amongst imagined things, not given alternatives. The segment contrasts 'objective optimality' (omniscient observer) with 'subjective optimality' (the enjoyment of a good state of imagination). The author concludes that while value theory provides essential principles of logic, it is fundamentally at odds with the flow of time and the originative nature of human choice. [Cost and the Meaning of Choice]: This segment explores the concept of cost as 'displacement cost'—the best alternative sacrificed. The author argues that cost implies the existence of rival alternatives, which sits uneasily with a perfectly determinist world-picture. Choice is defined as an originative act of imagination. The author also defends the role of emotion in action, asserting that reason is merely a tool for achieving ends that are chosen based on desires and feelings. The segment concludes that to claim conduct is guided by reason alone, without emotion, is a confusion of thought, as reason only shows the route once a goal has been chosen. [Perfect Competition and Conceptual Illusionism]: The author analyzes the role of 'perfect competition' in the value-construct. It is shown to provide three essential features: the simultaneous determination of price and quantity, the solution to the 'adding-up problem' (exact exhaustion of product), and production at minimum unit cost. However, the author points out internal contradictions, such as the firm assuming its output doesn't affect price while the market requires price to change with aggregate output. The segment also discusses the 'fallacy of composition' in applying partial equilibrium to the whole economy and the Sraffa dilemma regarding constant returns. Perfect competition is characterized as a necessary but elusive formal assumption. [The Value-Construct in the Round]: This segment summarizes the value-construct as a deductive system that treats economic events with the structural necessity of mathematics. It highlights the use of simultaneous equations to represent general equilibrium and the roles of Walrasian 'tâtonnements' and Edgeworthian 're-contract' in finding solutions. The author reiterates that this system is fundamentally timeless, as time and complete knowledge are incompatible. The value-construct is described as an 'arresting triumph of the formal imagination' that edifies reason but ultimately fails to reflect the real flux of history and the mystery of time. [Book III: Expectation and the Dissolution of Determinacy]: Book III begins by arguing that expectation and determinacy are incompatible. The author asserts that the introduction of wealth and durable assets destroys the basis of rationality because today's prices depend on conjectures about tomorrow's prices. Money is seen as a means of deferring choice in the face of ignorance. The segment critiques the Theory of Games for attempting to save rationality by assuming perfect knowledge of strategies. It also discusses Keynes's transition from the 'Treatise on Money' to the 'General Theory,' noting how his focus on the speculative bond market undermined the traditional theory of value. The author concludes that a world of perfect foresight would be timeless and event-less. [Involuntary Unemployment and the General Theory]: This segment analyzes Chapter 2 of Keynes's 'General Theory,' which attempts to explain how involuntary unemployment is logically possible. The author identifies two distinct explanations in the chapter: one based on money wages being too high relative to product prices, and another (hinted at on the last page) based on a mismatch between desired saving and intended investment. The author argues that the real obstacle to full employment is the disparate 'mix' of consumption and wealth-accretion desired by earners versus what employers are willing to offer. The segment concludes that marginal value-productivity becomes unmeasurable during times of high uncertainty, leading to unemployment. [Kaleidic Investment-Values and the News]: The author discusses the 'kaleidic' nature of investment-values, which are based on suggestive evidence rather than knowledge. Investment is seen as a structure cantilevered over a void of future time. The segment introduces 'elasticities of surprise' to formalize how 'the news'—unheralded and unforeseeable information—can abruptly transform asset valuations. The author critiques the use of stable functional notation for such fluid thoughts, suggesting that a classificatory or taxonomic approach might be more appropriate for a subject matter where uncertainty and speculation are essential. [Lender's Uncertainty and the Nature of Interest-Rates]: This segment provides a formal analysis of interest rates, defining them as the proportionate growth of debt over time. The author argues that interest arises from 'lender's uncertainty'—the fact that to lend is to exchange a known sum for an unknown sum. A gambling counter model is used to illustrate how the bond market operates through pure expectation and convention. The author asserts that the interest rate is an 'inherently restless' variable because its stability depends on a balance of contradictory views (Bulls and Bears). The segment also defines the 'stock of money' as simultaneous payment-potentials and concludes that interest rates are determined by the need to find willing holders for the existing stocks of bonds and money. [Liquidity: Its Nature and the General Theory]: The author explores the nature of liquidity, defining money as a 'medium of search' and a means of deferring decision until better information is available. Chapter 17 of the 'General Theory' is analyzed, focusing on the attributes of assets: yield (q), carrying-cost (c), and liquidity-premium (l). The author argues that money's high liquidity-premium allows it to stall the production of capital assets when their marginal efficiency falls below the interest rate. Liquidity is characterized as a substitute for knowledge, and the segment notes a circular relationship between wage-stickiness and the liquidity of money, both rooted in social convention. [Prices as Convention]: This segment argues that prices are often determined by convention rather than necessity. The author identifies five 'epistemic circumstances' that lead to price indeterminacy, including speculation and the lack of pre-reconciliation. Keynes's Chapter 12 is highlighted for its description of 'conventional' valuations on the Stock Exchange, where speculators try to guess the majority's future opinion. Hugh Townshend's interpretation is cited, asserting that expectations have a direct causal influence on all prices and that there is no stable equilibrium. The author concludes that price stability is an invaluable source of efficiency but is ultimately based on custom and the prevalence of shared illusions. [The Dissolution of Rational Determinacy]: The author summarizes the dissolution of the rational value-construct. Rational determinacy is shown to exclude speculation, novelty, involuntary unemployment, money (as an asset), and imperfect competition. The segment critiques the 'stationary state' as a meaningless declension from the timeless system. The author argues that the economic world is not self-contained but is inextricably bound with politics, technology, and power struggles. The segment concludes that a general economic explanation of economic affairs is a fallacy and that the economist should instead seek to describe potential responses to 'kaleidic shifts' in the environment. [Book IV: Statics and the Rejection of Time]: Book IV examines 'Statics' as the rejection of time in economic theory. The author argues that marginalism and the calculus provided a perfect formal apparatus for analyzing rational conduct, but only by assuming a timeless world. Rational choice requires full information, which is only possible for past or timeless matters. The segment discusses Marshall's 'operational' concept of utility and the 'subjective ideal' of reasoned economy. The author asserts that while static models are indispensable for logic, they are fundamentally divorced from the human predicament of experiencing time and novelty. [Simultaneous Equations and the Market Ideal]: This segment discusses the use of 'simultaneous' (co-valid) equations to represent the inter-action of economizing individuals. Quesnay's 'Tableau Economique' and Leontief's input-output analysis are cited as models of inter-organized activities. The author argues that the problem of ideal allocation is a problem of pre-reconciliation, which can only be logically achieved in a timeless system. The market is seen as the ideal mechanism for pooling conditional intentions and finding a general solution. The author concludes that theory must use mutually exclusive models (timeless vs. time-conditioned) that are combined extra-logically. [Partial Equilibrium and the Essential Imprecision of Economics]: The author critiques 'partial' or 'particular' equilibrium analysis, which focuses on the individual firm or commodity. While this method allows for detailed study, it contains internal inconsistencies, such as the firm treating price as given while the market requires it to change. The segment warns against the 'fallacy of composition' when scaling up partial analysis to general markets like labor. Marshall is credited with using partial equilibrium while recognizing the essential imprecision of economics. The author concludes that formal reasoning in economics is suggestively powerful but must be used with caution regarding its foundational assumptions. [The Rejection of Time and the Artefact of the Stationary State]: This segment analyzes the various 'faces of time' and how economic theory attempts to manage them. The author argues that rational choice requires pre-reconciliation, which is only possible in a timeless world. The 'stationary state' is critiqued as a 'monster'—a timeless system repeating itself along a meaningless dimension. The author discusses the limits of 'ceteris paribus' and the 'comparative static' method, suggesting that a 'kaleidic method' which views history as a succession of potentially disorderly shifts is more realistic. The segment concludes that theory must choose between the principle of reason and the reality of time. [Book V: Diachronism and Marshall's Accommodation of Time]: Book V explores 'Diachronism'—the assimilation of time to space. The author argues that the calendar-axis is an artefact of thought and that the past is not sufficient to determine the future. Marshall's 'Principles' is analyzed as an unremitting struggle to accommodate time within a rational framework. The segment critiques Marshall's 'long-period supply curve' for conflating the ex ante view of the participant with the ex post view of the analyst. Marshall's use of the 'Normal' and 'continuity' is seen as a way to find permanence at the heart of change. The author concludes with Marshall's warning that simple doctrines of value are necessarily false in a world of mutual modifying forces. [Capital, or the Time-Net of Production]: This segment presents a detailed analysis of capital as a 'time-net' of production. It combines the technological structure (input-output matrix) with the temporal sequence of embryonic products. The author introduces the concept of 'orientation'—the use-directed and time-directed nature of capital items. The Austrian theory of capital (Böhm-Bawerk) is examined, defining capital as time and measuring it through the 'average period of production.' The author argues that a longer period allows for a finer division of labor and more efficient technical methods. The segment concludes by noting that the Austrian theory, while brilliant, requires the extreme abstraction of a stationary state and excludes uncertainty and novelty. [The Average Period of Production and the Complexity of the Production Net]: Shackle examines the difficulties of defining an average period of production when durable tools and complex production nets are introduced. He argues that the presence of durable equipment and the inter-contributory nature of modern production necessitate valuation, which undermines the notion of a purely technologically determined period. The segment also explores the concept of 'impatience to consume' using a 'parcels' model to illustrate the transition between stationary states and the role of capital as a scarce resource. [Disinvestment, General Equilibrium, and the Critique of the Stationary State]: This section critiques the idea of orderly general disinvestment, arguing that the production net is organic and indivisible. Shackle contrasts the timelessness of general equilibrium theory with the necessity of an expectational 'orientation' of the capital list. He suggests that while the Austrian theory is limited by its reliance on the stationary state, its focus on time-orientation could potentially be unified with Leontief's input-output analysis to better map the technological and temporal destiny of capital items. [Business Cycle Engines: Theories of Natural Success vs. Capability of Error]: Shackle introduces the business cycle by distinguishing between 'Theories of Natural Success' (General Equilibrium) and 'Theories of Capability of Error' (Macro-economics). He traces the evolution of monetary theory and its integration with value theory through thinkers like Wicksell, Keynes, and Myrdal. A central critique is leveled at the 'black box' treatment of expectations in concepts like the natural rate of interest, which Shackle argues cannot be reduced to the rigid logic of general equilibrium. [The Epistemic Cycle and the Nature of Cyclical Unity]: Shackle explores the logical requirements for a theory of the business cycle, focusing on the role of time-lags and the co-existence of cyclical elements in the 'present moment'. He proposes the concept of an 'epistemic cycle' where action induces changes in perception, leading to cumulative processes of boom and slump. He concludes by questioning the arbitrary separation of economics from the broader stream of history and human affairs, suggesting that abstraction often masks the lack of a unifying principle. [History, Theory, and the Sovereignty of Theory]: This segment critiques Marshall's view that explanation and prediction are identical operations. Shackle argues that while history provides 'ready-made' facts for explanation, prediction is a 'theorizing in a vacuum' that requires the invention of possibilities. He advocates for a 'loose-textured' view of history that allows for human origination and freedom. Finally, he asserts the 'sovereignty of theory' as a creative act of composition rather than a search for a unique, objective truth, emphasizing the role of subjective thought in economic choice. [Epistemics versus Axiomatics: The Science of Imprecision]: Shackle discusses the tension between the humanities-based subject matter of economics and its drive toward quantification and natural science methods. He describes economics as the 'science of imprecision,' which uses tools like index numbers and aggregates to construct a language for policy while often ignoring the underlying inconstancy of human thoughts and expectations. He argues that while these 'looming phantoms' are necessary for administration, they should not be mistaken for precise contact with reality. [Languages for Expectation: Probability and Its Limits]: Shackle explores the formal requirements for a language of expectation, arguing that choice is among mutually exclusive thoughts rather than objective outcomes. He critiques the standard probability framework, distinguishing between structural (a priori) and experimental (frequency-based) treatments. He argues that probability is often inapplicable to 'crucial' or 'momentous' human choices because these systems are essentially unique, evolutionary, and 'explosive' rather than stable and repetitive like a die in a box. [The Conditions for the Application of Probability to Physical Systems]: This segment outlines the primary requirement for applying probability to physical systems: the system must be strictly circumscribed so that its potential performances can be categorized under a comprehensive list of mutually exclusive and exhaustive headings. [Probability as a Mode of Thought and Rational Probability]: Shackle explores the nature of probability, arguing it is a mode of thought rather than an inherent character of the natural world. He discusses the requirements for applying probability to physical systems, such as constancy of structure, and introduces Keynes's concept of rational probability as a logical relation between evidence and conclusions. [Keynes's Definition and the Subjective Element in Probable Inference]: This section critiques Keynes's Treatise on Probability, arguing that probable inference requires subjective judgment and imaginative hypothesis to fill gaps in evidence that logic alone cannot bridge. Shackle proposes that the 'rational' part of probability is identical to demonstrative logic, but the assembly of the evidential basis is a subjective, originative act. [The Principle of Indifference and Relative Frequency]: Shackle examines Keynes's Principle of Indifference as a requirement for symmetrical evidence. He contrasts Keynes's 'rational belief' with the frequency theory of probability, noting that while relative frequencies provide certain knowledge about classes, they offer little guidance for individual, unique instances in human affairs. [Subjective Probability and the Concept of Possibility]: Shackle introduces 'possibility' as a non-distributional alternative to probability for describing expectations. He argues that probability is ill-suited for unique, non-seriable experiments where hypotheses are rivals. He proposes a scale of 'disbelief' to represent the standing of imagined sequels to action. [Profit, Investment, and the Theory of Games]: Shackle defines profit as arising from the duality of valuation caused by imperfect knowledge and expectation. He critiques the Theory of Games for excluding 'surprise' and 'novelty,' arguing that business is a contest of superior imagination rather than a game with known, fixed rules. [Kaleidic Economics and the General Theory]: Shackle describes 'kaleidic economics' as the study of an economy subject to sudden re-adjustments and ephemeral equilibria. He analyzes Keynes's General Theory as an 'Economics of Disorder' that uses pseudo-equilibrium to capture the incalculable nature of investment and the impact of 'the news' on expectations. [Economic Theory Unbound: Conclusion]: In the concluding section, Shackle reflects on the limitations of traditional economic theory, which prioritizes reason and proportion over time, knowledge, and novelty. He advocates for a theory that acknowledges the epistemic problem and views profit as a signal for policy revision in a kaleidic economy.
