Former ECA used selective data to dwarf India's GDP figures: EAC-PM
19 June 2019
Former CEA Subramanian has cherry-picked a few indicators and performed a rather unconvincing regression analysis to prove his hypothesis that India’s GDP was over-estimated post 2011-12, the prime minister’s economic advisory council stated in a rebuttal of the former CEA’s claim.
The economic advisory council to the prime minister today released a detailed note titled ‘GDP estimation in India- Perspectives and Facts’ that bares the fallacy of Subramanian’s claims.
The PM-ECA highlights the absurdity in Subramanian’s paper that selectively ignores tax data based on the argument that the period post 2011-12 witnessed “major changes in direct and indirect taxes”.
Interestingly, Subramanian’s analysis ends on 31 March 2017, while the only major tax change (GST) was introduced on 1 July 2017.
The PM-ECA has highlighted a total of eight clear points with supportive facts and arguments to debunk Subramanian’s research paper in its entirety.
While admitting that India’s GDP estimation methodology is by no means a perfect exercise, the note said the ministry of statistics and programme implementation is working on multiple aspects to improve the accuracy of economic data.
However, the direction and pace of improvement is commendable and as of today India’s GDP estimation methodology is at par with its global standing as a responsible, transparent and well-managed economy. If anything, the weakness of Subramanian’s attempt to suggest that the growth numbers are over-estimated confirms that the estimation process is robust to spurious criticism, it pointed out.
“Going forward, Indian National Income Accounting is bound to change for good and an important step in accomplishing that will involve criticism from experts and academics. But the country’s interests are not served by imparting sensationalism through negativity that questions the credibility of the system,” it added.
The note provides a clear rationale for India’s switch to an improved GDP estimation methodology in January 2015. The new methodology that uses 2011-12 as the base year includes two major improvements:
- Incorporation of MCA21 database, and
- Incorporation of the Recommendations of System of National Accounts (SNA), 2008.
This change was in line with other countries that have changed their methodologies in line with SNA 2008 and revised their respective GDP figures. On an average, real GDP estimates saw an increase of 0.7 per cent among OECD countries, it pointed out.
The primary contributors to the note, namely BibekDebroy, Rathin Roy, Surjit Bhalla, Charan Singh and Arvind Virmani reject Subramanian’s methodology, arguments and conclusions on the basis of academic merit and grasp of Indian realities.
