Who They Were
Abhijit Banerjee (born 1961) is an Indian-American economist at the Massachusetts Institute of Technology and a central figure in modern development economics. Working from the 1990s onward, he became known for studying poverty through detailed empirical evidence rather than broad theory, focusing on the actual decisions poor households make about health, education, borrowing and work. With his collaborators he helped build a research program based on running carefully designed experiments in the field, often in India and across other low-income countries. In 2019 he shared the Sveriges Riksbank Prize in Economic Sciences with Esther Duflo and Michael Kremer for their experimental approach to alleviating global poverty. He has also written for general audiences, co-authoring widely read books that translate this research for non-specialists.
Key Contributions
Banerjee helped pioneer the use of field experiments, including randomised controlled trials, to answer specific questions in development economics. Instead of treating poverty as a single problem, he and his collaborators broke it into concrete, testable pieces - whether a particular incentive raises immunisation rates, or how credit affects small businesses - and measured the results directly. This experimental approach gave policymakers evidence about which interventions genuinely improve the lives of the poor. His 2019 Nobel, shared with Esther Duflo and Michael Kremer, recognised this contribution to alleviating global poverty. The methods he helped establish have reshaped development economics, moving the field toward rigorous evaluation of individual policies and away from reliance on untested assumptions about what helps poor communities.
