Amartya Sen

Biography

Amartya Kumar Sen, born November 3, 1933, in Santiniketan, West Bengal, is an Indian economist and philosopher known for his groundbreaking work in welfare economics, social choice theory, and development economics, which earned him the Nobel Prize in Economic Sciences in 1998. He began his academic journey at Presidency College, University of Calcutta, where he completed his undergraduate studies in economics, then went on to Trinity College, Cambridge, earning his PhD in 1959. Early in his career, he held positions at several prestigious institutions, establishing himself as a leading voice in economic theory and social philosophy.

Sen's most influential work focuses on the capability approach to human development, which changed how economists and policymakers view poverty, inequality, and social progress. Instead of just looking at income or utility, Sen argued that real development should be measured by people's ability to live the lives they value. This idea helped create the Human Development Index and influenced development policy around the world. His study of famines showed that they are caused not by food scarcity but by failures in food distribution systems and entitlements, challenging the usual understanding of hunger and poverty.

Throughout his career, Sen has been a faculty member at many institutions, including the London School of Economics, Oxford University, and Harvard University, where he was a Lamont University Professor. His work ties together economics, philosophy, and political science, exploring social justice, democratic governance, and human rights. Sen has written over 20 books, such as 'Development as Freedom' and 'The Idea of Justice,' which are key texts in development economics and political philosophy. His work on social choice theory, building on Kenneth Arrow's impossibility theorem, offered new insights into collective decision-making and democratic processes.

Besides his academic work, Sen is an active public intellectual, advising governments and international organizations on development policy. He has received numerous honors including the Bharat Ratna, India's highest civilian award, and continues to write and speak extensively on global justice and the role of democracy in development. In his personal life, Sen has been married three times: first to writer Nabaneeta Dev Sen, then to Eva Colorni, and currently to economic historian Emma Georgina Rothschild. Sen's influence goes far beyond economics, shaping current debates on human development, social justice, and the importance of democratic institutions in improving human welfare.
