Unit 3 — Institutional &
Behavioural Approaches
When markets are neither perfectly competitive nor populated by rational robots — how do institutions, transaction costs, power, justice, and human psychology shape economic outcomes? Nine Nobel laureates answer.
Why This Unit Matters: Units 1 and 2 built increasingly sophisticated models of how rational individuals and free markets work. This unit asks a fundamentally different set of questions: What if individuals are not fully rational? What if markets are embedded in institutions — rules, norms, laws, power structures — that shape outcomes as much as prices do? What if the commons can be managed without privatisation or the state? These questions make economics genuinely interdisciplinary — drawing on sociology, psychology, law, political science, and ecology.
Institutional Economics — Gunnar Myrdal & John Rawls
The Core Critique of Orthodox Economics: Original Institutional Economists (Thorstein Veblen, John Kenneth Galbraith, Gunnar Myrdal) argued that mainstream economics — whether Classical, Neo-Classical, or Keynesian — treated institutions as neutral backdrops when in reality institutions are the economy. Rules, habits, laws, social norms, power structures, and cultural practices determine who gets what — often in ways that entrench inequality rather than correct it. Markets are not natural givens; they are institutional constructs embedded in historical and social contexts.
🔄 Myrdal’s Theory of Circular and Cumulative Causation
Myrdal’s most powerful analytical contribution directly challenged the Neo-Classical assumption that market forces automatically push economies toward equilibrium and reduce regional or racial inequalities over time. He argued the exact opposite: market forces, left alone, tend to produce and intensify inequality through a self-reinforcing cycle of advantage and disadvantage.
Myrdal’s framework begins with a simple but devastating observation: poverty is not an equilibrium to be corrected by market forces — it is a self-reinforcing trap. Consider a poor region or community:
- Low income → Low savings → Low investment → Low productivity → Low income. The circle closes on itself. There is no automatic market mechanism to break out of it.
- Backwash Effects: When a prosperous region grows, it attracts capital, skilled labour, and entrepreneurship from surrounding poorer regions — draining them further. This is economic migration as a symptom of cumulative divergence, not convergence.
- Spread Effects: Growing regions do generate some demand for goods from poorer regions — but Myrdal argued that in practice, backwash effects dominate spread effects in developing countries, producing persistent regional inequality.
- Non-Economic Factors: Crucially, Myrdal insisted that economic analysis must incorporate non-economic factors — health, education, social attitudes, power relations, racial discrimination — as endogenous parts of the system, not exogenous “background conditions.” These factors interact with economic variables in reinforcing spirals.
In his monumental three-volume work Asian Drama: An Inquiry into the Poverty of Nations (1968), Myrdal analysed the persistent underdevelopment of South and Southeast Asian countries despite decades of post-colonial independence. His diagnosis was institutional, not economic: the core problem was what he called the “soft state.”
A soft state is one that lacks the institutional capacity and political will to implement policies — even well-designed ones — due to elite capture, corruption, patron-client politics, and the weakness of the rule of law. Development policy fails not because the economics is wrong but because the institutional environment cannot implement it. This was a direct challenge to economists who believed that if you got the prices right (World Bank’s 1980s structural adjustment programmes), development would follow automatically.
Myrdal also noted the role of social stratification — caste in India, class elsewhere — as a non-economic variable that profoundly shapes economic access, opportunity, and mobility. He insisted these social facts must be part of economic analysis, not ignored as “outside the model.” His work directly influenced development economists like Amartya Sen and Pranab Bardhan.
India’s persistent inter-state inequality is a textbook illustration of Myrdal’s cumulative causation. Maharashtra (with Mumbai as its engine) and Bihar represent opposite ends of a self-reinforcing divergence that has widened over decades despite democratic elections, five-year plans, and central government transfers.
Maharashtra’s per-capita income (FY2023) stands at approximately ₹2.72 lakh; Bihar’s is roughly ₹54,000 — a ratio of approximately 5:1. This gap has not narrowed significantly over 75 years. The backwash effects are visible in the massive migration of Bihar’s working-age population to Maharashtra, Gujarat, and Delhi — draining Bihar of its most productive workers (brain drain and labour drain) while adding pressure to urban infrastructure in destination states.
What keeps Bihar in the vicious circle? Low government revenue (itself a product of low income) → weak infrastructure spending → poor roads, electricity, connectivity → low private investment attractiveness → few manufacturing jobs → low wages → continued migration → further shrinkage of the local tax base. Breaking this cycle required deliberate institutional intervention — the Bihar government’s focus post-2005 on governance reform under Nitish Kumar (improving law and order as an institutional prerequisite for investment) produced GDP growth of 8–10%, demonstrating that institutional change can trigger the virtuous circle Myrdal described as its positive counterpart.
⚖️ John Rawls — A Theory of Justice
While Myrdal approached institutional economics through empirical social science, John Rawls approached it through moral philosophy — asking not “what does the economy do?” but “what economic arrangements are morally just?” His answer, developed in A Theory of Justice (1971), became the most important liberal challenge to both utilitarianism and libertarianism in 20th-century thought.
Rawls asks: how would rational people design a just society if they did not know in advance what position they would occupy in it? Imagine you must choose the rules of your society before knowing whether you will be born rich or poor, talented or average, able-bodied or disabled, majority or minority. You are behind a “Veil of Ignorance.”
From behind this veil, Rawls argues, rational self-interested people would choose two principles of justice:
- First Principle (Equal Liberty): Each person should have the most extensive set of basic liberties compatible with the same liberties for all. Freedom of speech, conscience, political participation — these are non-negotiable and cannot be traded for economic gains.
- Second Principle — The Difference Principle: Social and economic inequalities are only justifiable if: (a) they are attached to positions open to all under fair equality of opportunity, AND (b) they work to the greatest benefit of the least-advantaged members of society. This is the revolutionary element — inequality is permitted only when it helps the worst-off.
Rawls’s framework has concrete economic implications that distinguish it sharply from both utilitarian welfare economics and libertarian free-market thinking:
- Progressive Taxation is Justified: Redistributing from rich to poor is just — not merely utilitarian — as long as it genuinely improves the position of the worst-off. A 30% marginal tax on the wealthy that funds quality public education for the poorest passes the Difference Principle test.
- Fair Equality of Opportunity: It is not enough to have “careers open to talent” (formal equality). Rawls demands that people with equal talent and motivation should have equal chances regardless of their socioeconomic background. This requires significant investment in public education, healthcare, and removal of caste/class/gender barriers — something far more demanding than mere non-discrimination.
- Against Pure Meritocracy: Natural talents are “morally arbitrary” — you did not choose to be born intelligent, athletic, or in a supportive family. Therefore, the economic rewards from these unearned advantages must not be allowed to produce extreme inequality. Society is a cooperative venture, and the naturally talented owe something to the social arrangement that allows their talents to be productive.
- Basic Liberties Cannot Be Traded: Unlike Bentham, Rawls insists that individual rights and liberties cannot be sacrificed even for large aggregate welfare gains. This is the liberal check on utilitarian reasoning.
In India, Rawls’s framework speaks powerfully to debates about reservations (affirmative action for SC/ST/OBC communities), the Right to Education Act, universal healthcare, and the MGNREGS guarantee — all of which can be justified as institutional measures to improve the position of the historically worst-off.
New Institutional Economics I — Ronald Coase & Friedrich Hayek
The New Institutionalist Project: While original institutionalists (Myrdal, Veblen) tended to be critics of markets, the New Institutional Economics (NIE) used rigorous economic tools — transaction costs, property rights, information theory — to explain why real-world institutions (firms, contracts, laws, norms) exist and how they shape economic behaviour. The key insight: institutions arise to reduce the costs of transacting in the real world.
🏢 Ronald Coase — Why Do Firms Exist? (Transaction Costs)
Coase asked a deceptively simple question that mainstream economics had completely ignored: if markets are so efficient, why do firms exist at all? Why don’t individuals simply transact with each other through market contracts for every task, rather than gathering inside an organisation with a boss who gives orders?
His answer: using the market is not free. Every market transaction involves transaction costs — the costs of:
- Search and information costs: Finding out who can supply what you need, at what quality, at what price.
- Bargaining and decision costs: Negotiating the terms of exchange, drafting contracts, reaching agreement.
- Monitoring and enforcement costs: Ensuring the other party fulfils the contract, and enforcing it if they don’t.
Firms exist because internalising transactions within a hierarchical organisation can be cheaper than conducting them through markets, especially for complex, repeated, long-term relationships requiring coordination, specialised assets, and trust. The entrepreneur-manager replaces the price mechanism with administrative direction — “I’ll tell you what to do today” rather than “let’s negotiate a separate contract for every task.”
Firms grow until the cost of organising an additional transaction internally equals the cost of doing it through the market — this defines the optimal size of the firm. This insight explains: why Apple has 160,000 employees (not millions of individual contractors), why companies outsource some functions but not others, and why vertical integration strategies change with technology and information costs.
Coase’s 1960 paper — the most cited article in the history of legal scholarship — tackled a fundamental problem in welfare economics: what should be done when one person’s economic activity harms another (an externality)?
Pigou’s traditional answer (1920): tax the polluter to internalise the external cost (the “Pigovian tax”). Coase’s revolutionary response: the problem is symmetric — both the polluter and the victim are imposing costs on each other. The efficient solution requires asking who can avoid the harm at least cost, regardless of who is “to blame.”
The Coase Theorem states: if property rights are well-defined and transaction costs are zero, parties will bargain to the efficient outcome regardless of the initial assignment of rights. Whether you give the factory the right to pollute, or give the farmer the right to clean air, both parties will negotiate to the same efficient level of pollution — whichever party values the change more will compensate the other.
The practical significance: transaction costs are never zero. Coase’s deeper insight is that the assignment of legal liability matters enormously when transaction costs are high — which is almost always. The law should assign rights to whoever can most cheaply prevent the harm, minimising the need for costly bargaining.
India’s Perform, Achieve and Trade (PAT) scheme — launched in 2012 under the National Mission for Enhanced Energy Efficiency — is a cap-and-trade system for energy-intensive industries. Firms that reduce energy consumption below their target can sell “Energy Saving Certificates” (ESCerts) to over-consuming firms. This is a direct application of Coasian logic: define property rights in the form of pollution permits and let markets find the efficient allocation.
However, the scheme’s implementation has exposed precisely the transaction costs that Coase warned about. Information asymmetry (firms misreporting energy use), measurement and verification costs (third-party energy audits are expensive), thin market problems (too few buyers and sellers of ESCerts for liquid price discovery), and weak enforcement (penalties for non-compliance were initially minimal) all meant that transaction costs were far from zero. ESCert prices were volatile and low, and a significant number of designated consumers failed to meet targets without consequence.
The lesson is precisely Coasian: in a world of zero transaction costs, the scheme would work perfectly. In the real world of high transaction costs, institutional design — robust monitoring, credible enforcement, government backstop — is essential. Delhi’s air pollution crisis illustrates the same point at the macro level: with millions of emitters (vehicles, brick kilns, stubble burning) and impossibly high transaction costs of individual Coasian bargaining, regulatory standards (BS-VI emission norms, stubble burning bans) and Pigovian taxes (congestion charges) become necessary second-best alternatives.
🧠 Friedrich Hayek — The Knowledge Problem & Spontaneous Order
Hayek’s 1945 essay is one of the most important arguments in the history of economic thought — and it is fundamentally about information, not ideology. His core claim: the economic problem of society is not merely the allocation of given resources — it is the problem of utilising knowledge that is dispersed across millions of individuals and can never be centralised.
There are two types of economic knowledge:
- Scientific/Technical Knowledge: Can be written down, codified, and transmitted — the kind of knowledge a central planner could in principle gather.
- Tacit/Local Knowledge: “Knowledge of the particular circumstances of time and place” — the local factory manager who knows her machines are about to break down, the trader who senses that demand in a particular town will spike tomorrow, the farmer who understands the micro-climate of his specific plot. This knowledge exists only in particular minds at particular moments. It cannot be aggregated or transmitted to a central authority without being destroyed or distorted.
Therefore, the price system is not just a convenient mechanism for allocating resources — it is an irreplaceable information system. Prices aggregate the dispersed, tacit, local knowledge of millions of actors into a single signal that tells producers and consumers what to do. No central planner — however brilliant and well-intentioned — can replicate what billions of price signals do continuously and in real time. This is Hayek’s devastating theoretical argument against central planning, presented not as a political position but as an epistemological impossibility.
Hayek extended his knowledge argument into a general theory of social institutions. He distinguished between:
- Taxis (Made Orders): Deliberately designed institutions — constitutions, regulations, organisations. They reflect the intentions of their designers but are limited by what those designers could foresee.
- Kosmos (Spontaneous Orders): Institutions that emerge from human action but not from any single human design — markets, common law, language, money, moral norms. These encode more information than any designer could consciously grasp, precisely because they have evolved through the decentralised trial-and-error of countless interactions over time.
The market is the paradigmatic spontaneous order. It was not designed by anyone — it evolved. Its rules (property rights, contracts, currency) crystallised gradually through repeated human interactions. Hayek argued that the Great Society of free markets is sustained by abstract rules that individuals follow without understanding why — and that intellectuals who try to redesign these rules based on theoretical “social justice” models risk destroying the very order that makes complex civilisation possible.
Critical evaluation: Hayek’s knowledge argument is powerful and largely correct about the impossibility of Soviet-style central planning. However, critics note that he: (a) underestimated market failures (public goods, externalities, information asymmetry) that require institutional correction; (b) conflated all government intervention with totalitarianism (The Road to Serfdom); and (c) provided no criterion for distinguishing helpful from harmful institutions within spontaneous orders — custom and market outcomes that embed discrimination and inequality are also “spontaneous.”
New Institutional Economics II — Kenneth Arrow, Elinor Ostrom & Oliver Williamson
📊 Kenneth Arrow — Information Asymmetry & Market Failure
Arrow’s 1963 paper on health economics is one of the most important papers in the history of applied economics — it explains in rigorous theoretical terms why the healthcare market is fundamentally different from other markets and why it requires special institutional arrangements (insurance, regulation, public provision).
He identified several features unique to healthcare that violate all standard Neo-Classical assumptions:
- Demand Uncertainty: You cannot predict when you will need medical care or how much. This prevents normal consumer planning and creates the demand for insurance.
- Information Asymmetry: The doctor knows vastly more than the patient about diagnosis, treatment options, and quality of care. This violates the perfect information assumption and creates moral hazard (doctors over-treat when insurance pays) and adverse selection (sicker people disproportionately buy insurance, raising premiums, driving out healthy people).
- Non-Price Rationing: Medical care cannot be fully rationed by price — withholding care from those who cannot pay has ethical dimensions not present in, say, the market for refrigerators.
- Externalities: Vaccination and infectious disease treatment create positive externalities — protecting not just the patient but the entire community.
Arrow concluded: because healthcare markets systematically fail to achieve efficient outcomes due to these structural features, special institutional arrangements — insurance mandates, professional licensing, regulated providers, public health systems — are economically justified, not just ethically desirable. This remains the foundational argument for universal health coverage globally.
In his doctoral dissertation (published as Social Choice and Individual Values, 1951), Arrow proved one of the most disturbing results in all of social science: there is no voting system that can consistently aggregate individual preference rankings into a coherent collective preference ranking while satisfying all of the following reasonable conditions simultaneously:
- Non-dictatorship: No single individual’s preferences should automatically become society’s preferences.
- Pareto efficiency: If every individual prefers A to B, society should prefer A to B.
- Independence of Irrelevant Alternatives: Society’s ranking of A vs. B should not depend on the existence of a third option C.
- Unrestricted domain: The system must work for any possible set of individual preferences.
This result implies that democratic decision-making is inherently fraught — different voting systems produce different outcomes from the same individual preferences, and there is no “correct” aggregation method. For economics, it fatally undermines the idea that social welfare functions (used in welfare economics to evaluate policy) can be constructed from individual utilities without making controversial value judgements about how to weight different people’s preferences.
🌊 Elinor Ostrom — Governing the Commons Without the Market or the State
In 1968, Garrett Hardin published “The Tragedy of the Commons” — arguing that any shared resource (a common pasture, a fishery, an aquifer) will inevitably be overexploited and destroyed, because each user has an individual incentive to take as much as possible while the costs are shared by all. The only solutions, Hardin argued, were privatisation (assign individual property rights) or state regulation (government enforces limits).
This argument was enormously influential — it justified the privatisation of fisheries, forests, and water resources across the developing world, often with devastating social consequences for communities that had managed these resources sustainably for generations.
Elinor Ostrom spent decades conducting fieldwork — studying fishing communities in Maine, forest user groups in Nepal, irrigation systems in Spain and the Philippines, grazing commons in Switzerland and Japan — and found that Hardin was simply wrong about what communities do. Real communities had developed sophisticated, locally adapted institutional arrangements for managing commons sustainably — without privatisation and without state intervention.
From her comparative fieldwork, Ostrom identified eight institutional design principles that characterise successfully managed commons worldwide. These are empirically derived — not theoretical prescriptions:
- 1. Clearly Defined Boundaries: Who has the right to use the resource must be unambiguously defined. Ambiguity invites overuse.
- 2. Congruence with Local Conditions: Rules must fit the specific ecological and social context — no universal template works everywhere.
- 3. Collective Choice Arrangements: Most affected individuals should be able to participate in modifying the rules. Top-down external rules fail.
- 4. Monitoring: Monitors who actively audit both the resource condition and user behaviour — either members themselves or accountable to them.
- 5. Graduated Sanctions: Rule-breakers face penalties that escalate with severity and frequency of offence — proportionate, not draconian.
- 6. Conflict Resolution Mechanisms: Rapid, low-cost, local arenas for resolving disputes between users.
- 7. Recognition of Rights: External authorities (government) must recognise the legitimacy of the community’s self-governance — not override it.
- 8. Nested Enterprises: For large systems, governance is organised in multiple overlapping layers — local, regional, national.
India’s Forest Rights Act (FRA) of 2006 is a landmark legislation that directly embodies Ostromian principles — recognising the rights of tribal communities and other traditional forest dwellers to govern and manage forests they have inhabited for generations. Prior to the FRA, these communities had been classified as “encroachers” on state forest land, their centuries-old management systems legally invisible and often criminalised.
Empirical evidence from states like Odisha and Chhattisgarh — where Community Forest Resource (CFR) rights have been implemented under FRA — shows exactly what Ostrom would predict: communities with formal recognition of their governance rights show measurably better forest conservation outcomes than comparable forests under purely state Forest Department management. A 2019 study by the Rights and Resources Initiative found that tribal-managed forests under CFR rights in Odisha had significantly lower deforestation rates and better biodiversity indicators.
However, implementation has been deeply uneven — illustrating Ostrom’s Principle 7 (recognition of rights): in many states, the Forest Department and state governments have actively obstructed CFR implementation, rejecting claims and undermining community governance. As of 2023, only approximately 5 million hectares of the estimated 40 million hectares eligible for CFR recognition had been formally recognised — an 87% implementation gap driven by institutional resistance from the very state apparatus supposed to enable community governance.
⚙️ Oliver Williamson — Transaction Cost Economics & Organisational Governance
Williamson extended Coase’s transaction cost framework into a systematic theory of how organisations choose between market transactions, long-term contracts, and hierarchy (vertical integration). His key innovation was identifying what makes transactions costly and therefore what determines the most efficient governance structure.
Williamson identified three critical transaction attributes:
- Asset Specificity: The degree to which an investment loses value when deployed outside its intended relationship. A steel mill built next to a particular car factory (site specificity), custom software written for one client (human capital specificity), or a specialised machine tooled for one product (physical asset specificity). High asset specificity creates “hold-up” risk — after making the specific investment, you are vulnerable to opportunistic renegotiation by your trading partner.
- Uncertainty: The unpredictability of future conditions. High uncertainty makes complete contracting impossible (you can’t write a contract that covers all contingencies), creating gaps that allow opportunistic behaviour.
- Frequency: How often the transaction recurs. High-frequency transactions justify the fixed costs of setting up hierarchical governance.
When asset specificity is high, uncertainty is high, and frequency is high, vertical integration (hierarchy) dominates — because the hold-up problem makes market contracting dangerous and the costs of monitoring and renegotiating contracts are too high. When asset specificity is low, markets suffice. In between lie hybrid governance forms — long-term contracts, franchise arrangements, joint ventures, strategic alliances.
Behavioural Economics — Herbert Simon & Richard Thaler
The Fundamental Challenge: All economic theories from Smith to Hayek assume individuals are essentially rational — they know their preferences, process information correctly, and maximise utility or profit. Behavioural economics, drawing on cognitive psychology (especially the work of Daniel Kahneman and Amos Tversky), shows that this is empirically false. Humans are not rational maximisers — they are predictably irrational in systematic, measurable ways. And these predictable irrationalities have major implications for markets, institutions, and policy design.
🎯 Herbert Simon — Bounded Rationality & Satisficing
Classical and Neo-Classical economics assumes global rationality — the decision-maker has complete information, unlimited computational capacity, and consistent preferences, and therefore always finds the objectively optimal solution. Simon demonstrated that this is psychologically impossible and institutionally irrelevant.
Real human decision-making is constrained by three types of bounds:
- Cognitive Limitations: Human working memory is limited (Miller’s Law: we can hold roughly 7±2 chunks of information simultaneously). We cannot process all available information or compute all possible consequences of our choices. We use mental shortcuts — heuristics — to simplify complex decisions.
- Information Limitations: In the real world, information is incomplete, uncertain, costly to acquire, and sometimes unavailable. Decision-makers work with the information they have — which is always less than the theoretically perfect set.
- Time Constraints: Decisions must be made before all information is available and before all options can be evaluated. The manager who analyses every possible supplier endlessly will have no product to sell.
Given these bounds, Simon argued that real decision-makers do not optimise (find the best possible solution) — they satisfice (find a solution that is “good enough” relative to an aspiration level, and stop searching). The term “satisficing” combines “satisfy” and “suffice.” A firm doesn’t find the optimal wage — it pays enough to recruit and retain adequate staff. A consumer doesn’t find the objectively best laptop — they choose one that seems good enough and buy it.
🎯 Richard Thaler — Nudge Theory & Behavioural Biases
Thaler’s contribution was to take Simon’s bounded rationality and the empirical findings of Kahneman and Tversky’s Prospect Theory, and translate them into actionable policy through the concept of “nudges” — small, low-cost changes to the choice environment (choice architecture) that reliably change behaviour in predictable directions without restricting freedom of choice or changing incentives.
Thaler built on Kahneman and Tversky’s Prospect Theory (1979), which showed empirically that people do not evaluate outcomes in terms of final wealth levels (as utility theory prescribes) but in terms of gains and losses relative to a reference point. Moreover, losses hurt roughly twice as much as equivalent gains feel good — this is called loss aversion.
Example: Losing ₹1,000 causes psychological pain roughly equivalent to the pleasure of gaining ₹2,000. This single fact has profound implications:
- Endowment Effect: People demand more to give up something they own than they would pay to acquire it — because giving it up is a “loss.” Thaler demonstrated this with mugs: people who were given a mug demanded roughly twice as much to sell it as others were willing to pay. This violates standard utility theory.
- Status Quo Bias: People irrationally favour the current state of affairs — because changing incurs the psychological pain of “losing” the status quo. This explains why pension auto-enrolment works (see below).
- Mental Accounting: People treat money differently depending on its source and intended use — keeping separate “mental accounts” for salary, bonus, inheritance, gambling winnings — rather than treating all money as fungible as standard theory requires. A “bonus” is spent freely; the same amount as salary is carefully saved.
🧪 Key Cognitive Biases Documented in Behavioural Economics
Thaler and Sunstein’s Nudge (2008) proposed a policy philosophy they called “libertarian paternalism” — seemingly paradoxical, but coherent: preserve complete freedom of choice (libertarian) while designing choice architectures that steer people toward better outcomes for themselves (paternalism). The key tool is the nudge — changing the default option, the framing, or the information presentation to exploit predictable behavioural biases without coercion.
Nudges are powerful because they work with human psychology (status quo bias, loss aversion, social norms) rather than against it — and they are low-cost relative to taxation or regulation.
India’s demonetisation of ₹500 and ₹1,000 notes on November 8, 2016 — announced with 4 hours’ notice — is a fascinating case study in both the application of behavioural insights and the failures that result from ignoring them. The government’s implicit behavioural theory: the dramatic, sudden, irreversible nature of the announcement would prevent black money holders from converting their holdings (loss aversion — the pain of losing the money would exceed the gain from any workaround).
But the policy also revealed multiple behavioural failures in designing the implementation. Availability heuristic: policymakers focused on the dramatic images of black money hoards, underweighting the mundane but statistically massive role of ₹500/₹1,000 notes in everyday transactions by the informal economy’s 488 million workers. Overconfidence bias: officials drastically overestimated the speed of replacement printing and bank infrastructure. Present bias: the long-term goal (formalisation) was given priority over the immediate short-term disruption to livelihood — a trade-off the formal-economy policymakers did not adequately weight.
The result: 86% of currency by value was withdrawn overnight. GDP growth decelerated sharply in Q3 FY17. The informal sector (construction, agriculture, small trade) — which runs almost entirely on cash — took a severe demand shock. RBI data eventually showed that 99.3% of demonetised notes returned to the banking system, undermining the stated goal. A behavioural diagnosis: the policy over-relied on loss aversion as a deterrent while failing to account for the adaptive strategies (conversion through agents, benami transactions) that rational actors with sufficient stakes would predictably employ.

📌 Unit 3 — Big Picture Summary
- Myrdal showed that market forces reinforce, not correct, inequality through circular cumulative causation — poverty traps are self-sustaining. The “soft state” fails to implement even correct policies due to institutional weakness and elite capture.
- Rawls provided a justice-based alternative to utilitarianism: design institutions from behind a Veil of Ignorance. The Difference Principle — inequality is just only if it benefits the worst-off — justifies progressive redistribution, affirmative action, and universal public services.
- Coase explained why firms exist (transaction costs) and why Pigovian solutions to externalities can be inefficient (the Coase Theorem): well-defined property rights + low transaction costs → efficient bargaining. In the real world of high transaction costs, institutional design of rights assignments matters greatly.
- Hayek demonstrated the epistemological impossibility of central planning: the knowledge required to plan an economy is dispersed, tacit, and local — only the price system can aggregate it. Spontaneous orders (markets, common law, norms) encode more information than any designed institution.
- Arrow proved two devastating results: his Impossibility Theorem shows no voting system can consistently aggregate preferences; his work on information asymmetry shows healthcare and insurance markets fail systematically — justifying public provision and regulation.
- Ostrom empirically demolished the Tragedy of the Commons: communities around the world manage shared resources sustainably through locally adapted institutional arrangements. Her 8 Design Principles provide a practical framework for commons governance without privatisation or state control.
- Williamson extended Coase into organisational economics: the choice between markets, hybrids, and hierarchies depends on asset specificity, uncertainty, and frequency. Governance structures exist to minimise transaction costs — including the “hold-up” problem from asset-specific investments.
- Simon replaced the fiction of global rationality with bounded rationality — real decision-makers satisfice (find a “good enough” option) because they face cognitive, informational, and time limits. This requires institutions designed for real human decision-making, not idealised Homo Economicus.
- Thaler translated behavioural insights into policy through nudge theory: predictable cognitive biases (loss aversion, status quo bias, social norms) can be systematically used through choice architecture to improve outcomes without restricting freedom. Default options are the most powerful tool.
