Abhijit Banerjee, the India-born economist who was today declared joint winner of the 2019 Nobel Prize in Economics for his work in "fighting poverty", might be on top of the world but the 58-year-old could be in trouble back home for not having told his mother the wonderful news. Speaking to NDTV from her home in Kolkata, Nirmala Banerjee declared, in mock anger, "I haven't spoken to my son (since the award was announced) but I did speak to him last night. He did not mention this then. I will tell him off... he should have told me about it". (Video Courtesy: Brown University)
