Nobel laureate Abhijit Banerjee has weighed in on the controversy over the amended citizenship law that fast-tracks the process of giving citizenship to persecuted non-Muslims from three neighbouring countries. Mr Banerjee, who won the Nobel Prize for Economics with wife Esther Duflo and economist Michael Kremer last year, in a conversation with Dr Prannoy Roy says "we need to be extremely careful in designing institutions to make decisions that can have massive consequences" for people.
