I. The Problem with a Nobel Prize
Robert Shiller is not a bad economist. He is one of the most intelligent economists of his generation, and his record of intellectual courage is considerable. He warned about the dot-com bubble before it burst, about the housing bubble before it collapsed, and about speculative excess at moments when the profession was celebrating its own models of market efficiency. His willingness to take psychology, mood, and social dynamics seriously, at a time when mainstream economics regarded such concerns as unscientific, marks him as a genuinely independent thinker.
That is precisely why his most celebrated book, Narrative Economics, published in 2019, is so revealing. Not because it is wrong in an empirical sense, but because the particular kind of conceptual wrongness it displays tells us something profound about the deeper crisis of economic thought. The book's failure is a failure of ontology: a failure to inhabit the right kind of world before the theorizing begins.
Shiller opens Narrative Economics with a mission statement that is worth taking seriously on its own terms. He argues that economists have been systematically blind to the way popular stories shape economic behaviour. Narratives, he insists, are not mere decoration on top of rational economic calculation. They are causal forces. They drive investment, consumption, confidence, and panic. They spread through populations the way viruses spread through bodies. To ignore them is to leave the most important mechanism of economic change entirely outside the theoretical frame.
The prescription he offers is this: we need, in his words, "to incorporate the contagion of narratives into economic theory." Otherwise, he warns, "we remain blind to a very real, very palpable, very important mechanism for economic change." These are strong claims, and they are not entirely wrong. The problem is that they are answers to the wrong question.
II. The Ontological Starting Point
Every economic theory has an implicit picture of what economic life fundamentally is, what kinds of entities populate it, how they relate to one another, and what kind of processes drive its movement. Classical economics begins with isolated rational individuals (homo oeconomicus), equipped with pre-formed preferences, who receive external information, calculate their optimal responses, and aggregate their decisions into markets. The ontological picture is of a world of atoms and signals.
Like all the other proponents of behavioural economics, Shiller is well aware that this is inadequate. He quotes Keynes's devastating attack on the Immaculate Conception of the Indifference Curve, the assumption that consumer preferences are simply given in advance, as if they arrived in the world fully formed, untouched by social life, history, or material circumstance. For Keynes, and later for Shiller, this was an extraordinary intellectual evasion. Preferences are not pre-given. They are formed somewhere, through something, under conditions that matter enormously.
So far, so good. But notice what Shiller does with this insight. He does not ask: what is the actual process through which economic dispositions, expectations, and orientations are formed? He does not pursue the question of where preferences, confidence, and economic orientation come from in the full sense, through what lived processes, within what material and institutional conditions, embedded in what temporal rhythms and social relationships. Instead, he answers: they come from narratives.
The move is elegant. It preserves the fundamental structure of the orthodox picture while adding a new input channel. The architecture remains: individuals, with mental states, responding to external influences, producing economic outputs. What has changed is only the nature of those external influences. Before Shiller, the inputs were prices, wages, interest rates, and information. After Shiller, we add stories.
But this addition does not change the ontology. It merely populates it differently. The individual is still prior to society. The economic actor is still fundamentally an isolated mind receiving external signals. The signals now include symbolic narratives in addition to numerical data. That is a less wrong picture than pure rational choice theory. It is not a fundamentally different picture.
What would a fundamentally different picture look like? It would begin not with individuals who then encounter narratives, but with the prior conditions that make both individuals and narratives possible. It would recognise that human beings never exist as isolated units who subsequently enter social relations. They are constituted from the beginning through embodied routines, material environments, institutional structures, social positions, temporal rhythms, and collective expectations. Economic life does not begin when individuals start making decisions. It begins in the pre-reflective coordination of existence itself.
III. What the Epidemiological Model Cannot See
The centrepiece of Shiller's methodology is the application of epidemiological models to the spread of economic narratives. He is explicit and enthusiastic about this. He writes that "such contagion is the heart of mathematical models of the economy" and argues that the Kermack-McKendrick three-equation model, the standard SIR framework dividing populations into susceptible, infected, and recovered individuals, "still remains a workable model for idea epidemics." The appeal is obvious. Epidemiology is dynamic, nonlinear, sensitive to network effects, capable of explaining sudden explosions of adoption and rapid collapse. It looks nothing like the static equilibrium models that dominated economics for decades. It feels alive.
And yet the epidemiological analogy contains a fundamental philosophical error, one that reveals more about the limits of Shiller's framework than any empirical objection could.
The error concerns the nature of recursivity. A virus is a remarkable entity. It evolves through mutation and selection pressure, adapts to immune environments, exploits host density and transmission ecology, and generates nonlinear population dynamics of astonishing complexity. In this sense, viral spread is genuinely recursive: the spread changes the conditions for further spread, which changes those conditions again, in iterated loops that can generate explosions, oscillations, crashes, and long periods of apparent stability. Epidemiology had to develop entirely new mathematical tools to handle these dynamics, tools that departed sharply from the linear causal models that dominated earlier science.
But, and this is decisive, a virus does not model its own situation. It does not anticipate how its hosts will respond. It does not read the epidemiological literature about itself. It does not interpret public health announcements, adjust its transmission strategy based on media coverage, or develop expectations about the future behaviour of vaccination campaigns. Its recursion is evolutionary, operating through selection across generations, not through reflexive self-understanding in real time.
Economic actors are fundamentally different. They do not merely respond to economic conditions. They interpret those conditions. They form expectations. They anticipate what other actors will do. And crucially, they anticipate what other actors expect them to do, and they anticipate those actors anticipating their anticipations in turn. This is not a more complicated version of viral spread. It is a categorically different kind of process, what we might call interrecursivity: the mutual recursive modelling of agents who are each aware that the others are modelling them.
A stock market boom is not merely widespread belief in rising prices. It is recursive expectation about recursive expectation. Investors buy because they expect others to buy. Others buy because they expect still others to expect continued buying. Institutions support the process because they anticipate its continuation. Central banks watch and respond, and their watching and responding is itself anticipated by everyone else. Governments intervene because collapse threatens the broader recursive coordination on which everything else depends. At every level, present action is shaped by anticipated future states, which are themselves shaped by anticipated present actions of others, in a structure of nested anticipation that no epidemiological model can capture.
This is not merely a technical limitation of the SIR framework. It is a symptom of a deeper ontological error. The epidemiological model works by treating its subjects as passive carriers. The population is a substrate through which something moves. Individual members of the population do not alter the dynamic by interpreting it; they are simply counted as susceptible, infected, or recovered. Their subjectivity, their anticipatory intelligence, their capacity to respond to descriptions of themselves, is entirely irrelevant to the model's operation.
That is precisely what cannot be assumed in economics. Economic narratives do not merely spread through passive populations. They are actively interpreted, selectively believed, strategically deployed, institutionally amplified, and, most importantly, fed back into the very situations they describe. When Shiller writes that narratives about Bitcoin enthusiasm went viral, he is missing the most important feature of the phenomenon: the participants knew the narrative was circulating, they anticipated others' responses to it, and their knowing shaped their own responses in a loop that has no analogue in viral epidemiology.
IV. What Epidemiology Actually Does
There is something deeper than an analogy-gone-wrong at stake here. The choice of epidemiology as a model for economic narratives is not merely a useful heuristic that proves imperfect on inspection. It reveals something important about what modern science has and has not understood about recursive phenomena.
Epidemiology became one of the most powerful sciences of the modern period not because it discovered how to master complexity as such, but because it became extraordinarily good at a specific operation: isolating the least recursive components of what are actually massively interrecursive situations, and then modelling those components with mathematical precision. A real pandemic is not a purely epidemiological phenomenon. It is simultaneously a biological event, a political crisis, a media spectacle, a cultural experience, and a social disruption. Public interpretation changes compliance. Compliance changes transmission. Changing transmission changes institutional responses. Institutional responses change public trust. Trust changes future compliance. At every level, recursion folds back on itself.
The epidemiological model does not capture all of this. It cannot. What it does instead is perform a kind of selective reduction: it abstracts away the interpretive, anticipatory, and interrecursive dimensions of the pandemic and concentrates on the biological transmission dynamics that are most amenable to stable mathematical description. The predictive power of epidemiology comes precisely from this reduction, from the deliberate exclusion of the dimensions that are most thoroughly recursive. Where the reduction succeeds, prediction becomes possible. Where interrecursivity re-enters the field strongly, as it always does when populations begin interpreting the models being used to describe them, or when political dynamics overwhelm transmission patterns, the models break down.
This is not a minor flaw in epidemiology, it is its method. But it means that epidemiological success is always the success of managed reduction, not of genuine mastery over recursive phenomena. The sciences that borrowed epidemiology's framework, including the strand of economics that Shiller represents, inherited this reduction without inheriting the awareness that a reduction had taken place.
When Shiller imports the SIR model into economics, he is not adding a more sophisticated tool for understanding a complex world. He is performing the same selective reduction that makes epidemiological prediction possible, stripping away the interrecursive dimensions of economic life and modelling the residue. The narratives in his model are treated as if they were contagious particles: they spread from person to person through contact, generating adoption curves that rise and fall like epidemic waves. The fact that the adopters are interpreting the narrative, strategically positioning themselves relative to their models of others' interpretations, and feeding their responses back into the very narrative that is supposedly spreading, all of this disappears from the model.
The extraordinary irony is that Shiller never notices this has happened. He experiences himself as moving toward greater realism, toward a model that takes seriously what orthodox economics ignores. And relative to rational expectations theory, he is right. But the move toward narrative contagion does not escape the fundamental ontological limitation of mainstream economics. It replicates it in a new vocabulary.
V. Narratives Come Last
If the epidemiological framework gets the mechanism wrong, Shiller's treatment of narrative causality gets the temporal sequence wrong as well. Throughout Narrative Economics, stories appear as origins: they spread, generate beliefs, alter behaviour, and produce economic outcomes. The causal arrow runs from narrative to economy.
But consider the major phenomena Shiller analyses. The housing boom of the 2000s, in his account, was driven substantially by a viral narrative: that house prices always rise, that property is the surest path to wealth, that the moment to buy is always now. The narrative spread through dinner parties, media channels, mortgage broker conversations, and neighbourhood comparisons. Its contagion rates increased as more people adopted it, generating the recursive dynamic of speculative enthusiasm.
What is missing from this account is everything that made the narrative plausible, transmissible, and practically consequential. The housing boom required a decade of historically low interest rates, actively promoted by central bank policy. It required the political reconstruction of homeownership as a social entitlement, pursued by successive administrations across party lines. It required the development of mortgage-backed securities and their associated rating systems, which transformed local credit risks into globally distributed financial products. It required the suburbanisation of American life, the built environment of sprawling ownership that made housing the primary vehicle for family wealth accumulation. It required stagnating wages that made housing appreciation the primary route to middle-class financial security. It required generations of tax policy that treated mortgage interest as a subsidy worthy of public support.
In this context, the narrative that house prices always rise was not a cause. It was an expression, a symbolic crystallisation of a material and institutional reality that was already producing housing as the dominant coordination mechanism of middle-class economic life. The story became viral because the underlying conditions made it true, or made it appear true, for long enough that disbelief required enormous epistemic effort against the weight of lived experience. The narrative succeeded not because stories are contagious but because the mesocosmic conditions, the ensemble of material, institutional, temporal, and relational dimensions of economic life, had been systematically arranged to make homeownership the pre-eminent site of value accumulation and social belonging.
More precisely: the narrative came last. It was the symbolic articulation of a coordination that had already been achieved through other means. Workers did not first hear a story about housing wealth and then decide to buy houses. They lived in economies where wages were suppressed, where retirement security had been transferred from defined-benefit pensions to personal investment accounts, where the tax code rewarded ownership, where suburban infrastructure made renting expensive and marginal. The story about rising house prices was the audible surface of a deep structural alignment. When that alignment collapsed, when the underlying financial architecture proved to be built on fraudulent valuations and impossible leverage, the narrative collapsed with it. Not because the story became implausible in isolation, but because the material conditions that had underwritten its plausibility were revealed as fictitious.
This pattern recurs across Shiller's examples. Bitcoin enthusiasm was not primarily a narrative. It was a specific conjunction of post-2008 institutional distrust, generational exclusion from traditional wealth-accumulation pathways, digital infrastructure that made speculative participation frictionless, platform architectures that rewarded visible commitment, and a cultural formation in which technological disruption served as the primary vehicle of masculine aspiration. The narrative of decentralised currency was the symbolic layer atop this material and relational formation. Many people who bought Bitcoin had only the vaguest grasp of the narrative. They were responding to the social field, to the visibility of others' participation, to the ambient sense of an opportunity being foreclosed, to the prestige economy of early adoption, long before they had formulated any explicit story about what they were doing.
Shiller acknowledges, in various places, that materials conditions, institutional structures, and policy environments matter. But in his framework these function as background factors that set the stage on which narratives perform their causal work. In reality, the relationship is inverted. Narratives are typically the last thing to emerge in a process of coordination that has already been achieved through embodied routines, institutional arrangements, material affordances, and recursive expectation management. When a narrative becomes widely circulating and explicitly articulated, it usually signals that the underlying coordination is already well established, and sometimes that it is beginning to destabilise.
VI. The Mesocosm That Economics Cannot See
What Shiller cannot theorise, because his ontology does not contain a concept for it, is what we might call the mesocosm: the intermediate level of collective life that is neither the individual decision-maker of microeconomic theory nor the aggregate statistical pattern of macroeconomic modelling. The mesocosm is the actual domain in which economic coordination takes place: the level of shared routines, material infrastructures, institutional rhythms, class positions, temporal expectations, and practical orientations that make economic behaviour possible before any explicit decision is taken.
Most economic life happens at this level, and it happens without being experienced as economic at all. People commute. They pay rent. They shop at the same stores in the same sequence. They follow professional norms about how work is performed and compensated. They maintain household rhythms around consumption, saving, and debt service. They plan futures that fit within institutional frameworks they did not choose. These practices are the actual substrate of economic coordination. They do not require explicit narratives. They require only that the conditions of everyday existence remain recursively stable: that the money continues to function, that the employer continues to meet payroll, that the mortgage servicer processes payments as expected, that the infrastructure of supply chains delivers goods on schedule, that the regulatory environment maintains the legal conditions of contract and property.
When this substrate holds, economic life proceeds without requiring conscious coordination. Money, to use a phenomenological term, disappears. The payment system disappears. The supply chain disappears. The legal infrastructure disappears. These things become invisible precisely because they are working. Economic breakdown is always, at its deepest level, a breakdown of this invisibility: the moment when the pre-reflective substrate of coordination becomes visible because it has ceased to function reliably.
It is at precisely this level, the level of pre-reflective mesocosmic coordination, that the most significant economic transformations begin. Not with narratives. Workers sense, before they can articulate it, that the career trajectories that organised their parents' working lives have become unavailable. Young people feel, before they develop a political vocabulary for it, that homeownership is structurally foreclosed. There is a temporal fragmentation in everyday life, a shortened planning horizon, a shrinking of the future that appears habitable, that precedes any explicit story about precarity or stagnation. Trust in institutions erodes through accumulated small encounters that never rise to the level of narrative but gradually reorganise the practical orientation of entire generations.
These transformations are not invisible to Shiller. He observes their effects. But because he lacks a conceptual framework for the mesocosmic level, he can only recognise them at the moment they crystallise into explicit narratives. The narrative, in his account, is where economic reality becomes accessible. In fact, the narrative is often where economic reality has already begun to change, sometimes, where it has already peaked and begun to reverse.
VII. The Recursive Overheating of Modern Economies
Shiller is correct that contemporary economies have become more narrative-intensive. He is correct that social media accelerates the spread of stories and that digital platforms amplify emotional contagion. He is correct that modern central banking operates substantially through the management of expectations rather than through direct material intervention. These observations are important and underappreciated within mainstream economics.
But the deepest transformation of contemporary economic life is not that narratives have become more powerful. It is that the entire structure of interrecursive coordination has become denser, faster, and more unstable. This is not the same thing, and the difference matters enormously.
In earlier periods, institutions stabilised economic expectations over long time horizons. Employers offered career structures that extended across decades. Pension systems provided retirement security that did not require individuals to manage their own risk profiles. Housing markets moved slowly enough that ordinary planning horizons could encompass property cycles. National media created shared informational environments that changed slowly enough for collective orientation to remain stable. These institutional arrangements did not eliminate interrecursivity. But they managed it, they compressed recursive loops into longer time cycles, creating enough stability for anticipatory coordination to function without constant recalibration.
What digital platforms, high-frequency trading, real-time information environments, and algorithmically curated attention economies have done is not merely accelerate narrative spread. They have compressed the temporal structure of interrecursive coordination itself. Loops that once operated over months or years now close in hours or minutes. Expectations that once crystallised slowly through institutional mediation now form and dissolve in viral cycles. The recursive density of economic life has increased to a point where the stabilising functions of institutions are increasingly overwhelmed.
This is why contemporary financial markets exhibit a peculiar combination of hyperactivity and fragility. It is not that stories spread faster. It is that the entire anticipatory ecology of financial life has been restructured around compressed interrecursive loops that exceed the stabilising capacity of the institutional forms designed to manage them. Meme stocks, cryptocurrency manias, flash crashes, and sudden reversals of sentiment are not episodic failures of narrative management. They are symptomatic of a structural condition: economies in which the recursive density of expectation has outrun the temporal architecture of institutional stabilisation.
Central banking has recognised this, at least partially, even if it lacks the theoretical framework to articulate it clearly. The practice of forward guidance, the deliberate management of market expectations through carefully calibrated public communication, is an attempt to manage the interrecursive field directly, to stabilise anticipatory coordination by anchoring expectations to credible institutional commitments. When central bankers worry about 'unanchored expectations,' they are worrying about exactly what Shiller cannot theorise: the potential for self-reinforcing interrecursive dynamics to reorganise the entire field of economic coordination in ways that no narrative-contagion model can predict or control.
VIII. The Invisible Reduction
The deepest problem with Narrative Economics is not any particular claim it makes. It is the way its theoretical starting point was constituted long ebefore the book even begins yet remains completely invisible. Shiller never asks what had to be excluded from view before 'narratives spreading through populations' could appear as a plausible description of economic reality. He never notices that the image of isolated individuals exposed to contagious stories already presupposes an enormous reduction of what economic life actually is.
This reduction is not Shiller's personal error. It is inherited from the history of economics as a discipline, from the centuries-long project of purifying economic phenomena into abstract, mathematically tractable objects. The market, the price, the individual agent, the preference function: these are not natural kinds. They are the products of sustained intellectual labour aimed at constructing domains in which mathematical modelling becomes possible. What that construction necessarily excludes is everything that resists formalisation: the embodied, the relational, the temporal, the atmospheric, the intersubjective dimensions of economic existence.
The extraordinary achievement of mathematical economics was to make this exclusion invisible. So thoroughly was the reduction performed, so completely did its products become the natural furniture of economic thought, that economists ceased to experience their basic concepts as reductions at all. The individual with preferences, responding to price signals, appeared not as a highly purified abstraction but as the obvious starting point of any serious analysis. Complexity theory, behavioural economics, and narrative economics all arose within this framework, adding complications to the basic picture without questioning whether the basic picture was adequate to economic reality.
Shiller writes that most contemporary economists think public narratives are 'not our field.' He means this as a mild critique of standard economics. But the deeper problem is that by the time Shiller incorporates narratives into economic analysis, the concept of narrative has already been pre-shaped by the ontological framework it is meant to supplement. Narratives in Narrative Economics are detachable symbolic units, transmissible between individuals, capable of altering mental states, quantifiable through media databases and search engine frequencies. They are, in other words, objects that fit within the existing ontological furniture of economics: external inputs, measurable variables, causal factors.
What narratives are not, in this account, is what they actually are in human social life: moments of symbolic crystallisation within processes of ongoing interrecursive coordination that vastly exceed what any symbolic account can capture. The story about Bitcoin is not something that spreads through a population. It is something that emerges from, reinforces, and ultimately proves unable to sustain a specific configuration of material conditions, institutional failures, generational exclusions, and recursive anticipations that were already in motion before any story was told.
IX. The Transitional Position
None of this is to say that Shiller's work is without value. It has genuine value, both empirical and intellectual. His documentation of the relationship between narrative cycles and economic dynamics contains real insights. His historical comparisons illuminate aspects of speculative behaviour that orthodox models cannot reach. His insistence that mood, confidence, and social influence belong within economic analysis, not outside it, is an important corrective to the discipline's long suppression of these dimensions.
But the value of Narrative Economics is primarily diagnostic rather than constructive. It reveals, with unusual clarity, the point at which mainstream economics reaches the limits of its conceptual resources and begins, symptomatically, to reach for concepts that belong to a different kind of analysis altogether. The turn to narratives, like the turn to behavioural psychology and complexity theory before it, represents economics beginning to feel the inadequacy of its ontology without being able to articulate what an adequate ontology would look like.
Shiller is, in this sense, a transitional figure. He belongs to a generation of economists who sense that the old world is dissolving, that the models of equilibrium, rationality, and optimisation cannot account for what is actually happening in economic life, but who remain committed to the institutional and methodological forms of the discipline, and therefore cannot make the break that would be required for a genuinely different kind of theory. The result is what we see in Narrative Economics: a sophisticated, empirically grounded, intellectually honest attempt to extend the existing framework into territory it was never designed to cover, by means of a borrowed analogy that ultimately reproduces the limitations it was supposed to overcome.
The book ends up being most valuable not for what it explains but for what it cannot explain, and for the moments, scattered throughout, where the phenomena persistently exceed the model. Every time Shiller notes that a housing boom involved not just stories but credit conditions, regulatory environments, political incentives, and institutional structures; every time he acknowledges that narratives are embedded in prior social formations that shape their plausibility and reach; every time he reaches for the vocabulary of atmosphere, mood, or collective orientation, at those moments, the book is pressing against the limits of its own framework and pointing, inadvertently, toward a different kind of analysis.
X. The Economy as Recursive Coordinated World
What would an adequate economic ontology look like? It would begin not with individuals and their narratives but with the prior conditions of coordinated existence: the material, institutional, embodied, temporal, and relational dimensions that make economic life possible before any explicit action or articulation takes place. It would recognise that markets are not primary structures but emergent forms within a much larger and denser mesocosmic field. It would understand economic action as always already embedded in ongoing processes of interrecursive coordination that vastly exceed what any individual agent knows, intends, or can model.
Such a framework would treat narratives not as causes but as signals: moments at which the underlying process of mesocosmic coordination becomes symbolically audible. It would understand the timing and content of economic narratives as evidence about what is happening at the level of embodied routines, institutional rhythms, material affordances, and recursive expectation management, not as independent causal factors that can be studied in isolation through media databases and word-frequency analysis.
It would also understand economic instability differently. The volatility of contemporary financial systems is not primarily a symptom of narrative contagion. It is a symptom of recursive overload: of anticipatory ecologies whose interrecursive density has exceeded the stabilising capacity of the institutional forms designed to manage them. What is failing is not the clarity or content of narratives. What is failing is the temporal architecture of coordinated existence, the institutional structures, normative frameworks, and shared temporal horizons that once provided the scaffolding within which recursive expectation could be collectively managed.
This is the analysis that Narrative Economics cannot provide, not because Shiller lacks intelligence or care, but because the ontological starting point of the tradition within which he works forecloses it. The economy, in that tradition, is always already an aggregate of individual decisions. The question is always: what inputs are shaping those decisions? The answer, prices, incentives, information, narratives, changes from theory to theory, but the underlying picture remains stable. Individual minds, external inputs, behavioural outputs, aggregate results.
Economic life, in reality, is not like that. It is a form of shared existence, constituted through recursive coordination at multiple levels simultaneously, in which individuals, institutions, material conditions, symbolic articulations, and temporal horizons are so thoroughly entangled that no model which begins by abstracting the individual from this field can recover the field that was excluded. Narrative economics is not wrong because it exaggerates the power of stories. It is wrong because it mistakes the symbolic surface of a living coordinated world for the mechanism that drives it.
Shiller writes that Keynes "creates the world it is investigating." He means this as a critique of a specific piece of economic reasoning. He does not notice that the description applies, with equal precision, to the framework he himself inhabits, a framework that creates a world of narrative-bearing individuals from which the actual texture of economic existence has been systematically removed, and then offers the residue as an account of economic reality.
The “residue” is real. The reduction is enormous. And the scale of what has been excluded is the measure of how far economic thought still has to travel.
