NEW DELHI—Former Leader Financial Adviser Dr. Arvind Subramanian’s working paper claiming an overestimation of the nationwide Gross Domestic Product (GDP) by means of India’s statistics gadget between monetary years 2011-12 and 2016-17 has set the cat a few of the pigeons.
The important thing reason why for the talk: the previous CEA has claimed that India’s GDP between the monetary years 11-12 and 16-17 used to be hyped up by means of 2.five% in keeping with yr. Thus, the true enlargement charge of the GDP used to be four.five%. This implies India used to be now not the quickest rising financial system of its measurement that used to be up to now believed broadly. That Dr Subramanian used to be himself the CEA all over probably the most years cited within the learn about lends weight to his declare and research, and ammunition to critics who query why he didn’t talk out previous.
Those have been additionally the years all over which India changed each the bottom yr (from 2004-05 to 2011-12) it makes use of to calculate its GDP and the method used for doing so. In January 2015 and in overdue 2018, the Modi government carried out adjustments twice to India’s previous and provide GDP numbers. They’ve since been politically debatable because the efficiency of the UPA 2 govt appears worse compared to the NDA 2 govt.
The debate is a long way from settled. If the rest, Dr. Subramanian’s paper best provides to it by means of claiming that the overestimation used to be a results of the methodological adjustments carried out all over NDA 2, regardless that their spadework started all over the UPA 2 years.
The previous CEA additionally provides a technique to the talk. As he discussed in his piece for The Indian Specific, Dr. Subramanian favours the revisiting of India’s GDP estimation by means of an impartial process power comprising each nationwide and global statisticians, macroeconomists and different professionals.
HuffPost India explains the declare made by means of Dr Subramanian in his paper and the reputable protection by means of the Modi government to it, along with talking with a few of India’s reputed economists and statisticians to know what they’ve to mention concerning the declare made within the paper.
A) What’s Dr Arvind Subramanian’s key declare and what proof is it in accordance with?
In his paper, Dr. Subramanian claims that India’s GDP enlargement has been overstated by means of about 2.five proportion issues in keeping with yr after 2011 — implying the financial system in reality grew at about four.five% each and every yr, moderately than the reputable GDP enlargement determine of seven%. He concedes that the information to be had don’t seem to be granular sufficient to present in keeping with yr estimated GDP for the monetary years after 2011 until 2016-17.
The root for his declare lies in two steps followed by means of the ex-CEA within the paper for accomplishing his experiment. One, compilation of knowledge for the expansion of 17 signs which replicate task in an financial system and feature an instantaneous correlation with India’s GDP enlargement. They’re: electrical energy intake, 2-wheeler gross sales, industrial automobile gross sales, tractor gross sales, airline passenger site visitors, international vacationer arrivals, railway freight site visitors, index of commercial manufacturing, index of commercial manufacturing (production), index of commercial manufacturing (shopper items), petroleum intake, cement, metal, total actual credit score, actual credit score to business, exports of products and services and products, and imports of products and services and products.
Those 17 signs have been selected additionally as a result of they’re produced independently of the CSO and their information are when put next for the years from 2001 to 2017. What Dr. Subramanian discovered is that the speed of enlargement of the 17 signs is in sync with the GDP enlargement sooner than 2011. However within the years publish 2011, the speed of enlargement of those signs seems out of sync with the GDP. As an example, export (items and services and products) enlargement is 14.five p.c sooner than 2011 and a far much less three.four p.c within the years thereafter. This dip in exports is mirrored even supposing the financial system endured to develop in the similar vary as within the years sooner than 2011. There are corresponding figures for the opposite 16 signs within the paper which practice the similar development.
This, in line with the paper, is proof for mis-measurement. The ex-CEA then makes use of statistical fashions evaluating information from different nations and observes that the GDP enlargement in the ones nations used to be a lot lesser than India. Ploughing via some advanced information, the paper then estimates GDP overestimation by means of 2.five proportion issues by means of India’s statisticians.
b) What used to be the Modi govt’s reaction?
In an in depth statement, the Ministry of Statistics and Programme Implementation (MoSPI) stated, “The GDP estimates launched by means of the Ministry are in accordance with accredited procedures, methodologies and to be had information and objectively measure the contribution of quite a lot of sectors within the financial system.”
It defined that the adjustments to the bottom yr and method for calculating GDP have been made as in keeping with the newest global statistical requirements made up our minds in the course of the Machine of Nationwide Accounts (SNA) within the yr 2008 developed via discussions by means of member states within the United Countries. The United Countries Statistical Fee followed the SNA 2008 in 2009.
The SNA 2008 is the root for the adjustments made to the bottom yr (from 2004-05 to 2011-12) for calculating the nationwide GDP in January 2015.
“With any Base Revision, as new and extra common information assets grow to be to be had, you will need to be aware comparability of the previous and new collection don’t seem to be amenable to simplistic macro-econometric modelling,” it stated. The observation additionally famous that the GDP enlargement projections introduced out by means of quite a lot of nationwide and global businesses are “extensively in keeping with the estimates launched by means of MoSPI”.
If he had simply stated it’s unexplained, it could had been alright. He has overreached by means of pronouncing that that is an overestimation: Former Leader Statistician of India Dr Pronab Sen
c) How are economists and statisticians responding to the declare?
There isn’t a novel view amongst India’s statisticians and economists concerning the Dr. Subramanian paper, even supposing there was a consensus that the nationwide GDP figures require to be higher defined. Here’s what economists and statisticians who spoke with HuffPost India stated.
Dr Pronab Sen, former Leader Statistician of India
He has long past too a long way in his interpretation. As a result of what he may have completely appropriately stated is if we had used the previous manner of estimating the GDP, then the GDP enlargement would had been four.five%. So 2.five% of enlargement is left unexplained.
Now to mention that this 2.five% is solely overestimation is unsuitable. It’s unexplained, sure. However the clarification may well be that there’s overestimation or it may well be that there are different drivers of enlargement that are doing it.
And the 2 large different drivers of enlargement are enhancements in productiveness and enhancements in product high quality. You take into accounts Maruti promoting 800s and so they transfer their manufacturing to Dzire. The worth of Dzire is 2 and a part occasions the worth of the 800. That pushes up the GDP. And productiveness is apparent. This is you produce an identical quantity at lesser price. Those two can also be very sturdy drivers of enlargement. In reality, within the advanced nations, maximum enlargement comes from those two components. It doesn’t come from volumes.
So if he had simply stated it’s unexplained, it could had been alright. He has overreached by means of pronouncing that that is an overestimation.

An try to examine the GDP numbers from 2004-05 base yr and 2011-12 base yr is difficult. By contrast to the sooner episodes, the shift to the brand new 2011-12 base yr used to be accompanied by means of complete adjustments to the method and knowledge assets. It’s by means of now broadly documented that there are problems with the 2011-12 base yr. On the identical time, it will have to be famous that the 2004-05 base yr additionally had size problems. There used to be a dialogue about overstatement of services and products sector within the 2004-05 collection. Due to this fact to imagine the 2004-05 base yr collection as sacrosanct because the paper by means of the Ex CEA considers at the flooring that it had top correlations with probably the most actual sector variables like IIP, credit score might not be suitable.
Estimation of GDP via a number of regression specs can be utilized to expand a coincident indicator that may function a proxy to evaluate the state of the financial system. It can be too simplistic to offer an estimate of GDP via regression specification. There are a selection of databases utilized by the statistical company that are outdoor the researchers’ ambit. One of the crucial believable causes for over-estimation the paper attributes to is the transfer to value-based means from volume-based. The transfer used to be in keeping with global absolute best practises. So whilst there are demanding situations in estimation, the ones wish to be addressed moderately than attributing the overestimation to the shift to the brand new method. There’s a want for a complete debate about assets, strategies and deflators used within the 2011-12 collection. In parallel, there’s benefit in growing tactics to evaluate the state of the financial system impartial of GDP
