Social Choice Theory:

Sen extended Kenneth Arrow's work on social choice theory, exploring how individual preferences can be aggregated to form collective decisions. His Impossibility of a Paretian Liberal (1970) highlighted conflicts between individual rights and collective welfare.

Development as Freedom:

In Development as Freedom (1999), Sen argued that development should be understood as the expansion of freedoms, including political liberties, economic facilities, social opportunities, transparency guarantees, and protective security.
-
Famine and Poverty Analysis:
-
Sen's work on famines, particularly Poverty and Famines (1981), demonstrated that famines are often caused by failures in distribution and entitlement rather than absolute food shortages.
-
Gender Inequality and Human Development:
-
Sen has been a vocal advocate for addressing gender inequality and improving human development indicators, such as education and health.
-
Ethics and Economics:
