Economics asks how scarce resources are allocated. Politics asks who holds power and how it is used. Political economy insists the two cannot be separated: markets are shaped by rules, and rules are shaped by power. For a practitioner, it is the study of why policies live or die.

Lasswell's phrase is the whole field in one line. Every budget, subsidy, tariff and posting is an answer to it. Political economy reads the distribution behind the policy — and the power behind the distribution.

Practitioners are puzzled when a technically sound reform — a cleaner subsidy, a better tariff, an honest procurement rule — is never adopted, or is adopted and quietly reversed. The reason is rarely ignorance. It is that the reform reshuffles winners and losers.

Until the late 19th century, the discipline was called political economy — the study of how nations produce and distribute wealth, inseparable from the state. Smith, Ricardo, Malthus, Mill and Marx all wrote in this tradition before 'economics' narrowed the lens.

In The Wealth of Nations (1776), Adam Smith argued that individuals pursuing their own interest in competitive markets are led, as if by an invisible hand, to outcomes that serve society — without intending to.

Smith is caricatured as a prophet of greed. In fact he distrusted merchants' conspiracies, warned against monopoly, supported public goods and education, and in The Theory of Moral Sentiments grounded markets in sympathy and justice.

It is the strongest case in economics for trade — both parties can gain. But Ricardo says nothing about how the gains are shared, or who bears the losses when an industry is wiped out. That silence is where political economy enters.

Karl Marx turned political economy into a critique of capitalism. He argued that profit comes from surplus value — the gap between the value workers produce and the wages they are paid — making class conflict structural, not accidental.

The lazy debate pits 'free market' against 'big state'. The real question is the division of labour between them: markets are powerful coordinators, but they fail in predictable ways, and only collective authority can fix those failures.

In The Great Transformation (1944), Karl Polanyi argued that the 19th-century attempt to create a self-regulating market — treating land, labour and money as ordinary commodities — was a radical, destabilising experiment, not a natural order.

Land is not just an asset; it is a place people belong to. Labour is not just a commodity; it is human lives. Pretending otherwise provokes a reaction.

India's 1991 liberalisation expanded markets; the subsequent decades brought a counter-movement of rights-based guarantees — NREGA, the Right to Food, the Forest Rights Act. The 2020–21 farm-law repeal was a vivid double movement in real time.

Not geography, not culture, not natural resources alone. The dominant modern answer is institutions — the rules, written and unwritten, that shape incentives to invest, innovate and cooperate. Get the rules wrong and no amount of aid or advice sticks.

North founded New Institutional Economics. His insight: institutions reduce uncertainty and transaction costs. Where property is secure and contracts enforced, people invest for the long run.

In Why Nations Fail (2012), Daron Acemoglu & James Robinson argue prosperity turns on whether institutions are inclusive — broad rights, level playing field — or extractive — designed to funnel wealth and power to a narrow elite.

Millions of consumers would gain from cheaper, cleaner policy; a handful of producers gain from the status quo. Yet the producers win. Why do large groups with a common interest so often fail to act on it? This is the collective action problem.

In The Logic of Collective Action (1965), Mancur Olson showed that rational individuals will free-ride on a shared benefit rather than pay to provide it — so large groups under-provide their own collective goods unless specially organised.

A shared, finite resource — a grazing pasture, a groundwater aquifer, a fishery — tends to be over-used when each user gains the full benefit of taking more but shares the cost of depletion. Garrett Hardin called this the tragedy of the commons (1968).

Elinor Ostrom showed Hardin was not destiny. Across forests, fisheries and irrigation systems worldwide, communities do govern commons sustainably — without either privatisation or top-down state control. She won the 2009 Nobel Prize in Economics.

Not all rent is bad: a temporary innovation rent rewards risk. The danger is rent created by artificial scarcity — a permit you must bribe for, a quota only insiders get.

When the most profitable activity is capturing favours rather than serving customers, talent and capital flow to lobbying, not production. The whole economy is poorer for it.

India's pre-1991 Licence Raj required permits for capacity, imports and expansion. The system created vast rents: a licence was worth a fortune, so firms competed to win permits rather than win markets.

This is the most dangerous form: not breaking the rules, but writing them. Once captured, a state can look clean on paper while serving a narrow elite by design.

Even well-meant programmes are vulnerable. Elite capture occurs when local powerful groups divert benefits — subsidised inputs, scheme funds, the best plots — meant for the poor.

After 1945, a few economies — Japan, South Korea, Taiwan, later China — transformed from poor to rich in a generation, while others stagnated. The political economy of development asks what kind of state made the difference.

Chalmers Johnson (Japan) and later Alice Amsden (Korea) and Robert Wade (Taiwan) documented states that did not just fix market failures but governed the market toward industrialisation.

The key was reciprocal control: the state gave firms cheap credit and protection, but only if they hit hard export targets. Underperformers lost support. Subsidy was a contract, not a gift.

Counter-intuitively, resource-rich countries often grow slower and govern worse. Oil, gas and minerals generate huge rents that detach rulers from citizens, fuel conflict, and crowd out other industry. This is the resource curse.

This is acute for South Asia: services and informal work absorb labour leaving farms, but the high-productivity manufacturing path that lifted East Asia is narrowing. The escalator is shorter than it used to be.

Donors export the institutions of rich countries — independent regulators, merit bureaucracies, anti-corruption agencies — and watch them wither. The institutions are real on paper but powerless in practice. Why?

Khan's key move: stop asking 'are these the right institutions?' and start asking 'are these institutions compatible with how power is actually distributed here?'

Informal institutions — norms, conventions, networks of caste, kin and patronage — often govern behaviour more powerfully than the formal law. A bribe norm, a caste hierarchy, an understanding about 'whose turn' it is can override any statute.

Khan's framework is not counsel of despair. It directs effort to reforms that are compatible with the existing balance — or that shift it gradually — rather than ideal reforms that the powerful will simply kill.

PEA took the theory of Sections 1–8 and turned it into a practical diagnostic now used across DFID/FCDO, the World Bank, USAID and many NGOs. It is the working analyst's main political-economy tool.

Early PEA produced sweeping country studies that sat on shelves. The influential shift — led by analysts like David Booth — was to problem-driven PEA: start from a specific, concrete problem your programme faces, not the whole nation.

Structures are the deep, slow-changing features that constrain everyone: economic geography, demography, the resource base, history, the global position, social structure (caste, class, ethnicity).

Within structures sit institutions — the formal rules (laws, mandates, budgets, electoral systems) and the informal ones (norms, patronage, 'how things are really done').

Finally the actors: who has a stake, what they want, what they stand to gain or lose, and how much power they have to act on it. This is the most operational layer — the one you can actually engage.

Thinking and Working Politically (TWP) turns PEA from a one-off report into a way of operating: read the politics continuously, back local reformers, stay flexible, and adapt as the situation shifts.

Good applied PEA begins by naming the problem sharply: not 'weak governance' but 'frontline health workers are absent three days a week in this district'. The sharper the problem, the more usable the analysis.

An official's job description says one thing; the incentives they actually face — transfers, postings, side-income, political loyalty — often say another. PEA asks what behaviour the system is really rewarding.

Recall Section 1: reforms have concentrated losers and diffuse winners. The political-economy task is to organise the winners — give the diffuse beneficiaries a champion, a voice, and a stake worth defending.

What worked in Rwanda or Korea rests on that settlement, that capacity, that history. Transplanted whole, 'best practice' becomes isomorphic mimicry — the form copied, the function absent.

The constructive response is PDIA — Problem-Driven Iterative Adaptation: start from a locally-felt problem, take small steps, learn fast from what works, and let solutions emerge rather than importing them.

India is a paradox: a durable democracy with a vast, ambitious state that often delivers poorly. Its political economy is shaped by democratic competition, deep social cleavages, and a powerful but unevenly capable bureaucracy.

Pranab Bardhan, in The Political Economy of Development in India (1984), argued that India's slow growth reflected a stand-off between three dominant proprietary classes — industrial capitalists, rich farmers, and the professional/bureaucratic elite.

Atul Kohli compared how different states drive (or fail to drive) industrial transformation. In the Indian case he traced the shift toward a closer state–business alliance and a more pro-business (not always pro-market) tilt from the 1980s.

India's federalism is a continuous bargain between the Centre and the states over taxes, transfers and authority — mediated by the Finance Commission, the GST Council and party competition. Much of India's political economy is this Centre–state negotiation.

Caste is not a residue of the past but an active force in India's political economy — structuring access to land, credit, networks, education and the state itself. Class and caste overlap and cross-cut in ways no purely economic analysis captures.

Recent decades brought a wave of rights and transfers — MGNREGA, the food security and forest rights acts, DBT, free rations and cash schemes. This welfare expansion is itself a political-economy phenomenon: competitive democracy delivering to the poor as voters.
