# Amartya Sen

> Amartya Kumar Sen is an Indian economist and philosopher at Harvard University and Trinity College Cambridge, awarded the 1998 Nobel Memorial Prize in Economic Sciences for his contributions to welfare economics and social choice theory. Sen revitalized the study of social welfare functions, demonstrating that Arrow's impossibility theorem does not preclude rational social choices if the interpersonal comparison of utility levels is permitted. He developed the capability approach — the idea that human welfare is best measured not by income or utility but by the actual capabilities individuals possess to lead lives of value. This framework influenced the design of the United Nations Human Development Index and reshaped how international development agencies assess poverty and progress. Sen's work on famines revealed that famines result from failures in entitlement and political economy rather than from absolute food shortages, influencing famine prevention policy worldwide. He has also made significant contributions to gender economics, inequality measurement, and the relationship between democracy and development.
