Esther Duflo is a French-American economist who studies development economics. This field focuses on how to reduce global poverty and improve living standards. She is currently a professor at the Massachusetts Institute of Technology (MIT). Duflo is also the president of the Paris School of Economics. Her work is important because it uses scientific methods to test social programs. She wants to know which specific actions actually help people escape poverty. By finding what works, her research helps governments make better decisions for their citizens.

To find these answers, Duflo uses a method called randomized controlled trials (RCTs). An RCT is a type of scientific experiment used in social science. Researchers divide a group of people into different sets. One set receives a new type of help, while the other set does not. By comparing these two groups, scientists can see if the help caused a real change. This process helps rule out other reasons why things might improve. It allows researchers to see the direct effect of a single policy or tool.

Duflo applies this experimental approach to many different areas of life. She studies microeconomics, which looks at how small units like families make decisions. Her research covers several specific topics. These include health, education, and financial inclusion, which means helping people access banking. She also studies gender roles and political economy. By looking at these small details, she can understand the larger systems of poverty.

Her journey began in France, where she was born in 1972. Her father was a mathematics professor and her mother was a pediatrician. Her mother often traveled to support children affected by war. This background likely influenced Duflo's interest in helping others. She studied history and economics at the École Normale Supérieure in Paris. Later, she moved to the United States to pursue a PhD at MIT. While studying in Moscow, she realized that economics could be a tool for real-world action.

One of her most famous early studies focused on education in Indonesia. She used a large-scale school expansion program as a natural experiment. The study showed that more schooling led to higher wages in adulthood. This provided important evidence that education directly improves future earnings. Another study in India looked at remedial education programs. Duflo and her team found that targeted teaching helped children learn much better than just providing new textbooks. This led to the creation of the "Teaching at the Right Level" program.

In addition to her studies, Duflo co-founded the Abdul Latif Jameel Poverty Action Lab (J-PAL). This is a research center based at MIT that promotes the use of RCTs. J-PAL has grown into a massive global network. As of 2024, it includes 900 researchers at 97 different universities. The network has offices in many places, including Chile, South Africa, and Indonesia. By the year 2020, programs tested by J-PAL researchers had impacted more than 400 million people.

Duflo's work has earned her many of the highest honors in science. In 2019, she was awarded the Nobel Memorial Prize in Economic Sciences. She shared this prize with Abhijit Banerjee and Michael Kremer. They were recognized for their experimental approach to fighting global poverty. She also received the John Bates Clark Medal in 2010. Duflo has written influential books, such as "Poor Economics" and "Good Economics for Hard Times." These works help explain the complex nature of poverty to a wider audience.
