On the fiscal impact of DBT, the Chief Economic Advisor said, "We estimate that in 2014-15, savings could be as much Rs 12,700 crore, which is a lot of money. But savings will be lower this year at around Rs 6,500 crore."
"It's necessary that we don't overestimate the gain and under-recognise possible cost of doing this and in the case of DBT and Pahal, we have some preliminary evidence to suggest that a lot of it is elimination of ghost beneficiaries, but we can't rule out that there could be exclusion of genuine beneficiaries," he said.
Subramanian, formerly a senior Fellow at Peterson Institute for International Economics, admitted: "We were expecting commercial sales to go up by a huge number, but actually, this did not happen... There was only 6 per cent increase."
