The Nobel Memorial Prize in Economic Sciences has been awarded to Abhijit Banerjee, Esther Duflo, and Michael Kremer "for their experimental approach to alleviating global poverty".

Duflo became only the second woman to win a share of the award.

The Royal Swedish Academy of Sciences announced it had selected them on Monday. Their prizes will be formally presented, along with those of other Nobel Laureates, at a lavish banquet in Stockholm, Sweden on Dec 10, which is the anniversary of the death of Alfred Nobel, the industrialist and scientist after whom the awards are named. The king of Sweden will present the winners with medals, certificates, and 9 million kronor ($918,000) in each discipline. A maximum of three people can share each prize each year.

The academy said it selected Banerjee, Duflo, and Kremer because of their research into the "daunting issue" of global poverty. It said they tackled the issue by breaking it down into smaller questions that could be better asked and answered. It said they looked into how best to improve the health of children by examining their educations, health systems, agricultural approaches, and access to credit.

Forty-six-year-old Duflo, who is the youngest person to win the prize, said current turbulence in global economics can be traced back to a changing world order.

"I think we live in turbulent times when many individuals in rich countries are deeply concerned about their position in the world," she said. That anxiety is "at the root of much of the turbulence we are seeing".

Kremer conducted field experiments in the 1990s on how various interventions improved academic results for children in Kenya. Banerjee and Duflo conducted similar experiments in India.

Banerjee and Duflo are married and based at the Massachusetts Institute of Technology. Kremer is an academic at Harvard University.

The prize, which is officially known as The Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel, is generally thought of as the most prestigious award in the field of economics and has been presented annually since 1969. Unlike the other Nobel prizes, it was not established in 1901 based on instructions contained in Nobel's will but was set up by Sweden's central bank, Sveriges Riksbank, to mark its 300th anniversary. It is, however, managed by the Nobel Foundation, along with the other Nobel prizes.

The Nobel Prize in Economics was the last in a series of Nobel prizes for 2019 to be announced in recent days; following on from prizes in medicine, physics, chemistry, literature, and the highly coveted Nobel Peace Prize
