Despite the euphoria over PM Narendra Modi’s move to demonetise Rs 500 and Rs 1,000 currency notes, opinion is divided over the outcome. While there is a consensus that it will affect sectors like real estate and the demand for gold, economists are not convinced that the move is enough to rein in black money, one of its primary objectives. “Demonetisation won’t have the ultimate effect on black money. It’s just one of the things the government can do,” says Shashanka Bhide, economist and director, Madras Institute of Development Studies. “A number of other things need to be done, including better tax administration as most of the black money goes through the leakages there. We need to expand the tax base and make tax collection more efficient.”
