EAC-PM takes on former CEA Arvind Subramanian's paper on India's GDP

In a research paper, Subramanian has said that India's real GDP growth was more likely to have been 3.5-5.5 per cent in 2011-2016

A day after former chief economic advisor said real gross domestic product (GDP) growth had averaged 4.5 per cent in 2011-2016 and not 6.9 per cent as estimated by the National Statistical Office (NSO), the Economic Advi­sory Council to the Prime Minister (EAC-PM) said it would examine Subram­anian’s paper and issue a point-by-point rebuttal.

“It is felt that any attempt to sensationalise what should be a proper academic debate is not desirable from the point of view of preserving the independence and quality of India’s statistical systems, all of which the former is familiar with,” said a statement from the

“These are certainly issues that Dr Subramanian must certainly have raised while he was working as CEA, though by his own admission, he has taken time to understand India’s growth numbers and is still unsure,” it said.

In a research paper that analyses data on 17 different economic indicators in the non-financial sector, Subramanian has said that India’s real growth “was more likely to have been 3.5-5.5 per cent” in the 2011-2016 period. He said that the new series overestimated real growth by 2.5 percentage points.

This has reignited the debate on the accuracy of GDP numbers.

Subramanian analysed out­put volume-based data, such as the index of industrial production, exports and im­ports, footfall of tourists, auto sales, airline passenger traffic, and electricity and petroleum consumption am­ong others, to make his claim. He concluded his paper by saying, “the entire methodology and implementation for GDP estimation must be revisited by an independent task force”.

The EAC-PM, however, said that the base year of income calculations shifted to 2011-12 on the basis of recommendations of several committees with experts in national income accounting. “Therefore, it is wrong to suggest that the views of experts have not been taken into account while changing the base year,” it said.

“Dr Subramanian has used cross-country regressions to estimate what GDP should be. This is the most unusual exercise, as is the suggestion that any country’s GDP that is off the regression line must be questioned. The proxy indicators that he used can also be questioned. Nor does this exercise allow for GDP increases on the basis of productivity gains,” the statement said.

On Tuesday, the also released a statement rebutting Subramanian’s paper. It said the estimation adheres to global norms and is an output of a complex exercise.

“It is important to note that a comparison of the old and new series is not amenable to simplistic macro-econometric modelling,” it said.
