Famines are caused not by food shortages but by failures of work and wages, his Nobel-winning research proved.
Amartya Sen was born in Santiniketan, Bengal, in 1933. At the age of nine, he witnessed the Bengal famine of 1943, which killed an estimated two to three million people.1 The memory stayed with him. Decades later, his research would demonstrate that the famine occurred not because Bengal lacked food, but because wages collapsed and laborers lost the ability to buy what was available.2
Sen studied at Presidency College in Calcutta and Trinity College, Cambridge. His 1981 book Poverty and Famines overturned the conventional assumption that famines result from a decline in food supply. Sen showed, through comparative data from Bengal, Ethiopia, Bangladesh, and the Sahel, that famines occur when certain groups lose their "entitlements," their ability to acquire food through work, trade, or transfer.3
The implication was that the relationship between labor and survival is mediated by institutions, not simply by nature. People starve not because food does not exist, but because the economic system has deprived them of access to it.
In 1998, Sen received the Nobel Memorial Prize in Economic Sciences for his contributions to welfare economics and social choice theory.4 His "capability approach," developed across several works, argued that economic development should be measured not by GDP or income but by what people are actually able to do and become.5
The United Nations' Human Development Index, introduced in 1990, was directly inspired by Sen's work. It measures national progress through life expectancy, education, and per capita income rather than aggregate output alone.6 Sen continues to teach at Harvard. His central argument, that work has value only insofar as it expands what human beings can genuinely do with their lives, remains one of the most significant challenges to the assumption that employment and well-being are the same thing.
