## Contributions
Amartya Sen has made transformative contributions to economic theory, development studies, and social philosophy. His work spans decades and includes:

- **Social Choice Theory**: Sen’s foundational work in social choice theory, particularly his 1970 book *Collective Choice and Social Welfare*, revolutionized the understanding of how individual preferences can be aggregated into collective decisions. This work earned him the Nobel Prize in Economic Sciences in 1998.
- **Poverty and Inequality**: His research on poverty measurement led to the development of more nuanced indices, such as the Sen Index, which accounts for both the depth and severity of poverty. This approach has influenced global poverty metrics and policy decisions.
- **Development as Freedom**: In his 1999 book *Development as Freedom*, Sen redefined development as a process of expanding human freedoms rather than merely increasing income. This perspective has had a lasting impact on international development policy and the work of organizations like the United Nations.
- **Famines and Entitlements**: His seminal 1981 book *Poverty and Famines: An Essay on Entitlement and Deprivation* challenged the Malthusian view that famines are solely caused by food shortages. Instead, Sen demonstrated that famines often occur due to failures in food distribution, even when food is available. This work reshaped famine response strategies globally.
- **Capability Approach**: Sen’s capability approach, developed over decades, emphasizes that development should be measured in terms of people’s real opportunities to achieve well-being. This framework underpins the Human Development Index (HDI) used by the United Nations Development Programme (UNDP).
- **Gender Inequality and Women’s Agency**: Sen’s early work on gender inequality, particularly in his 1990 article “Gender Inequality and Theories of Justice,” brought attention to gender disparities in mortality and education, influencing global gender policy.
