On October 14, 2019, Esther Duflo was asleep in her home in Cambridge, Massachusetts, when the phone rang at 4:45 in the morning.
Her first thought wasn’t “I’ve won the Nobel Prize.” It was simply: who could possibly be calling at this hour?
She answered the phone and was told she had won the 2019 Nobel Memorial Prize in Economic Sciences. Her immediate response was: “With whom?”
When they replied, “Abhijit Banerjee and Michael Kremer,” she reportedly laughed and handed the phone to her husband, Banerjee, who had just woken up beside her. Then came another surprise: she needed to be ready for a press conference within forty-five minutes.
At just 47 years old, Esther Duflo had become the youngest person ever to win the Nobel Prize in Economics. She was also only the second woman to receive the honor — and the first female economist ever awarded the prize.
But what truly mattered wasn’t only who won. It was why.
For years, Duflo, Banerjee, and Kremer had been quietly changing how the world approached poverty. Instead of relying on huge theories and broad assumptions, they asked a much simpler question: what if poverty could be studied piece by piece?
Rather than trying to “solve” poverty all at once, they focused on smaller, measurable problems. Would free school uniforms improve attendance? Would smaller class sizes help students learn more? Would farmers benefit from access to fertilizer? How could vaccination rates actually be increased?
Their breakthrough was adapting randomized controlled trials — commonly used in medicine — to economics and poverty research. They tested specific policies in real communities, measuring actual results rather than relying on ideology or guesswork.
At the time, this approach was revolutionary.
Beginning in the 1990s, their field experiments expanded across countries including Kenya, India, and Indonesia. Instead of sitting in universities theorizing about poverty, they worked directly in villages and communities, observing how people actually lived and what interventions genuinely helped.
And they discovered something important: poor people were not irrational. They were making logical decisions based on limited resources, risk, and information.
Some findings challenged popular assumptions. Research showed that microcredit loans, once praised as a miracle solution, often failed to transform lives the way policymakers expected. Other studies revealed that small interventions — like deworming medicine for schoolchildren or tiny incentives for vaccines — could dramatically improve outcomes at surprisingly low cost.
In 2003, Duflo co-founded the Abdul Latif Jameel Poverty Action Lab at MIT to expand this work globally. By 2019, its research had influenced programs affecting hundreds of millions of people.
When Duflo accepted the Nobel Prize, she emphasized that the fight against poverty must be built on evidence, not assumptions. She also spoke proudly about representing women in economics, a field still dominated by men.
Esther Duflo didn’t claim to have solved poverty.
What she proved was something equally important: even the world’s biggest problems become less impossible when we break them into questions small enough to answer honestly.
