What Raghuram Rajan Thinks Of Currency Demonetisation

I am not quite sure if what you meant is demonetise the old notes and introduce new notes instead. In the past demonetisation has been thought off as a way of getting black money out of circulation. Because people then have to come and say "how do I have this ten crores in cash sitting in my safe" and they have to explain where they got the money from. It is often cited as a solution. Unfortunately, my sense is the clever find ways around it.

They find ways to divide up their hoard in to many smaller pieces. You do find that people who haven't thought of a way to convert black to white, throw it into the Hundi in some temples. I think there are ways around demonetization. It is not that easy to flush out the black money. Of course, a fair amount may be in the form of gold, therefore even harder to catch. I would focus more on the incentives to generate and retain black money. A lot of the incentives are on taxes.
