New GDP back-series data hurts credibility: Ex-CEA Arvind Subramanian

Former chief economic advisor Arvind Subramanian said on Sunday the new gross domestic product back-series data, released late last month by the Central Statistics Office and NITI Aayog, raised a lot of questions and hurt the credibility of official data.

“As an economist I have to say it (the new series) has created a lot of questions. If you look at the other indicators during that period, you see a difference between what those indicators show and what the recent back-series shows. It demands an explanation,” Subramanian said. 

Currently a visiting lecturer at Harvard University, Subramanian is in New Delhi for the launch of his new book.
