The Bengal Famine

Amartya Kumar Sen was born on November 3, 1933, in Santiniketan, a small town in Bengal known primarily as the home of Rabindranath Tagore’s experimental university, Visva-Bharati. Tagore himself chose the boy’s name — Amartya, meaning “immortal” — a detail that Sen has recounted with characteristic modesty, noting that Tagore gave names to many children in the community and was not making a prophecy. Sen’s family was academic: his father was a chemistry professor at Dhaka University, and his maternal grandfather was a scholar of Sanskrit and ancient Indian philosophy. The household was multilingual, cosmopolitan, and steeped in the Bengali intellectual tradition that valued argument, plurality, and the persistent questioning of received wisdom.

The event that shaped Sen’s life and work more than any other occurred when he was nine years old. In 1943, the Bengal famine killed an estimated two to three million people in conditions of grotesque suffering. Sen witnessed it firsthand. He later recalled a man stumbling into the family’s garden, desperately asking for food. The man, a Muslim day laborer named Kader Mia, had come into a Hindu area looking for work because he had nothing to eat. He was stabbed on the street. He died in the hospital that evening. The boy was shattered by the event, and it planted questions that would drive his work for the next eight decades: why do famines happen? Who suffers and why? What do we owe each other?

Years later, Sen would demonstrate that the Bengal famine was not caused by a shortage of food. Rice production in Bengal in 1943 was actually higher than in several non-famine years. The famine was caused by a catastrophic failure of entitlements — the economic and legal mechanisms through which people command food. War-driven inflation, speculative hoarding, and the colonial government’s prioritization of military supplies destroyed the purchasing power of rural laborers and fishermen, who starved surrounded by adequate food supplies. The famine was a social and political failure, not a natural disaster. This insight — that people starve not because there is not enough food but because they cannot get access to it — would become one of the most important ideas in development economics.

Sen studied economics at Presidency College in Calcutta and then at Trinity College, Cambridge, where he completed a PhD on the choice of techniques in developing economies. His early academic work was in social choice theory, the branch of economics and philosophy concerned with how individual preferences can be aggregated into collective decisions. Kenneth Arrow’s impossibility theorem, published in 1951, had demonstrated that no voting system could simultaneously satisfy a small set of apparently reasonable conditions — a result that many interpreted as proving the impossibility of rational collective choice and, by extension, the meaninglessness of “social welfare.”

Sen found this conclusion too hasty. In a series of papers through the 1960s and 1970s, he showed that Arrow’s impossibility result depended critically on the assumption that individual preferences contained only ordinal rankings — that you could say you preferred A to B, but not by how much. If interpersonal comparisons of well-being were permitted, even in a partial and imprecise form, the impossibility dissolved and meaningful social evaluation became possible again. This was not a mere technical fix. It was a philosophical argument that the information base of welfare economics — what we allow ourselves to know about people’s lives — determines what we can say about justice and social welfare. An economics that restricts itself to revealed preferences and refuses to compare the well-being of different people will inevitably find that it cannot say anything useful about poverty, inequality, or the design of social institutions.

Poverty and Famines

Sen’s 1981 book Poverty and Famines: An Essay on Entitlement and Deprivation brought together his empirical work on famines with a theoretical framework that changed how economists and policymakers understood hunger and deprivation. The book examined four major famines — the Bengal famine of 1943, the Ethiopian famine of 1972-74, the Bangladesh famine of 1974, and the Sahel drought — and demonstrated that in none of these cases was aggregate food availability the binding constraint. In each case, specific groups lost their entitlements to food through shifts in relative prices, loss of employment, or the collapse of exchange relationships.

The entitlement approach, as Sen called it, shifted the analytical focus from aggregate supply to the distribution of command over resources. A fisherman who normally exchanges his catch for rice may starve if the price of rice rises faster than the price of fish, even if total food production is unchanged. A laborer may starve if a flood destroys not the food supply but the employment that gives him the means to buy food. Famine, in Sen’s framework, is a failure of the economic system to maintain the entitlements of vulnerable groups — and the most effective remedy is not simply growing more food but protecting and expanding the mechanisms through which people access it.

The policy implications were profound. Sen argued that famines do not occur in functioning democracies, because democratic governments face electoral and media pressure to respond to food crises. India, which had experienced repeated famines under British colonial rule, had not had a major famine since independence in 1947 — not because its food production had outpaced population growth, but because its democratic institutions created accountability. China, by contrast, suffered the greatest famine in human history during the Great Leap Forward of 1959-61, in which an estimated thirty million people died, partly because the absence of a free press and political opposition allowed the catastrophe to continue unchecked.

The Capability Approach

Sen’s most influential intellectual contribution is the capability approach, developed over a series of lectures, papers, and books from the late 1970s onward, and given its most accessible expression in Development as Freedom (1999). The argument begins with a deceptively simple question: what is development for? The conventional answer — growth in per capita GDP — struck Sen as radically incomplete. GDP measures the aggregate value of goods and services produced, but says nothing about how those goods are distributed, whether people can use them to live the kinds of lives they have reason to value, or whether the social and political conditions exist for meaningful human flourishing.

Sen proposed an alternative: development should be understood as the expansion of human capabilities — the real freedoms that people have to be and do what they value. These capabilities include not just material well-being but health, education, political participation, the ability to appear in public without shame, and the freedom to make choices about one’s own life. A country with high GDP but severe gender discrimination, inadequate healthcare, or authoritarian governance is not, on this view, truly “developed,” regardless of what the national accounts say.

The capability approach was philosophical in its foundations — Sen drew on Aristotle’s conception of human flourishing and engaged in sustained dialogue with the political philosopher Martha Nussbaum, who developed her own version of the framework. But it also had immediate practical consequences. The United Nations Development Programme’s Human Development Index, introduced in 1990 under the leadership of the Pakistani economist Mahbub ul Haq, was directly inspired by Sen’s work. The HDI combined measures of income, life expectancy, and education into a composite index that offered a richer picture of human well-being than GDP alone. It was not a perfect operationalization of the capability approach — Sen himself acknowledged its limitations — but it shifted the terms of global development discourse permanently.

The Idea of Justice

In The Idea of Justice (2009), Sen extended the capability approach into a comprehensive theory of justice, positioning it against the dominant Rawlsian tradition. John Rawls’s theory of justice, Sen argued, was a form of “transcendental institutionalism” — it asked what perfectly just institutions would look like, rather than asking how to reduce injustice in the real world. Sen proposed a comparative approach to justice, focused on ranking social arrangements by the capabilities they actually deliver to real people, rather than designing ideal institutions from behind a veil of ignorance. The aim was not a theory of the perfectly just society but a framework for identifying and remedying manifest injustice — a distinction that, in Sen’s view, made the theory both more realistic and more useful.

Nobel 1998 and Critiques

Sen was awarded the Nobel Memorial Prize in Economics in 1998 “for his contributions to welfare economics,” a citation that encompassed his work on social choice, poverty measurement, famine, and the capability approach. He was the first Asian to receive the prize, and the award was widely seen as recognition not just of technical achievement but of a vision of economics that placed human well-being, in its fullest sense, at the center of the discipline.

The most persistent critique of Sen’s work is that the capability approach is easier to state than to operationalize. If development means the expansion of a multidimensional set of capabilities, how do we measure it? How do we make trade-offs between different capabilities — between health and education, between freedom and material comfort? Sen has been deliberately reluctant to specify a fixed list of capabilities or a formula for weighting them, arguing that such specification should emerge from democratic deliberation rather than philosophical fiat. Critics, including Nussbaum, have argued that this openness risks leaving the approach too vague to guide policy.

Legacy

Amartya Sen has been, for half a century, the conscience of economics — a thinker who insisted, against the grain of a discipline increasingly devoted to mathematical formalism and revealed preference, that economics is ultimately about human lives, human freedoms, and the social arrangements that make both possible. His work on famines showed that the worst deprivations are political failures, not natural ones. His capability approach provided an alternative to the reductive identification of development with GDP growth. His contributions to social choice theory demonstrated that meaningful evaluation of social welfare is possible, even in a world of diverse values and imperfect information. The nine-year-old boy who watched a man die of a preventable catastrophe spent his life building the intellectual tools to ensure that such catastrophes would be understood, and perhaps prevented. That the tools remain imperfect is not a failure; it is an invitation, still open, to continue the work.
