The country's economy is going through a difficult situation but not in a crisis, Niti Aayog distinguished fellow Ramgopal Agarwala said. The reforms like demonetisation, GST and the Insolvency and Bankruptcy Code (IBC) were required but hastily implemented, Agarwala said in his personal view. "Black money was running sore on the economy. But more thinking had to go in for implementing demonetisation," Agarwala said.
