Graduate Scholar at Harvard University Prateek Kanwal wrote at open letter to Prime Minister Narendra Modi after his dig at Harvard economists at a rally in Maharajganj. In an emphatic interview to NDTV, Prateek Kanwal says it is unbecoming of the PM's stature to mock economists and adds that the government's demonetisation policy was flawed and that the government must be willing to engage with opposing ideologies.
