Abhijit Banerjee, Economics Nobel winner this year along with Esther Duflo and Michael Kremer, recently delivered a sharp critique of the Indian economy and rated the fall in consumption as "extremely serious". The 58-year-old was speaking at Brown University last week when he spoke about institutions turning into "zombies" and investment nosediving. He also blamed centre's big-ticket economic decisions - demonetisation and implementation of Goods and Services Tax - for what he called a "demand problem". "I talk to my business friends. And they say that it is impossible to invest, you don't know who is going to call you up and say that's not the right thing to do," Abhijit Banerjee said on October 9 at Watson Institute, Brown University.
