New Delhi, Feb 26 (ANI): Chief Economic Adviser Arvind Subramanian on Friday said the World economy is increasingly glooming and there is scope to ease Indian Monetary Policy. He called for liquidity to be injected into the financial system and easing of policy rates by the Reserve Bank of India (RBI). The economists in the Finance Ministry have offered several empirical insights on these issues and more. The Economic Survey suggests that these outliers will eventually revert to the mean.
