IMF Chief Economist Gita Gopinath shared a picture on Twitter with former RBI Governor Raghuram Rajan and Nobel laureates Esther Duflo and Abhijit Banerjee from their pre-Diwali celebrations. Several Twitter users responded to the picture with one saying, "That's some serious firecracker brainpower in one room." "Probably the most intelligent square meter in the world right there," another said.
