Demonetisation and the GDP: knock-out punch or mild tap? (Hindu)

The CSO has been consistent with its methods, allowing little room for suspicion of window dressing.

Did demonetisation deal a knock-out punch to the Indian economy? Or was it just a mild tap from which it is already recovering?

This debate should have been settled with the latest second advance estimates from the Central Statistics Office (CSO) which peg FY17 GDP growth at 7.1%. But commentators who believe that the economy has suffered a debilitating blow from the note ban are not willing to rest their case here. They have flagged a long list of issues with these GDP numbers, apart from hinting that the numbers are fudged.

However, this is taking the criticism a little too far. A closer analysis of the CSO’s estimates suggests that, contrary to perception, they do factor in the impact of the note ban. And while India’s GDP estimation method could certainly do with improvements, the CSO has been both transparent and consistent with its methods, allowing little room for suspicions of window-dressing.

Why so high?


First, the sceptics ask, how did the GDP growth for FY17 turn out to be so high? The 7.1% number is unchanged from the CSO’s initial estimates and is also well above the 6.5%-6.8% growth estimated by most private forecasters. Is the CSO implying that vacuuming up 86% of cash in circulation had no impact on the economy?

Well, that is a wrong reading of the numbers. To gauge the actual level of economic activity, Gross Value Added (GVA) is the more pertinent number than GDP. The GVA measures the value of output created by different segments of the economy. Indirect taxes (minus subsidies) are added to it, to arrive at the GDP.

The GVA for FY17, as per CSO data, does show a dent from demonetisation. At 6.7%, it has registered a sharp decline of 110 basis points from 7.8% (revised estimate) for FY16.

While GVA growth is pretty close to private forecasts, what lifted the GDP is the strong 12.3% surge in indirect taxes that the CSO estimates for this fiscal. This is a plausible number, given that the Centre’s indirect tax collections already surged by 25% in April-December 2016, powered by higher excise duty on fuel and service tax.

There is no obfuscation here, because assessing the GVA and adding back net taxes is the global prescription for GDP estimation by the output method.

Too mild?


So the CSO does admit that economic activity has been impacted by the note ban. But isn’t it estimating too mild an impact, with the Q3 GVA growth at 6.6%, against 7% last year?

Commentators cite some key indicators to ‘prove’ that economic activity shrank in the note ban months. For instance, two-wheeler sales collapsed by 22% year-on-year in December, banks reported anaemic loan growth at 5%, cement despatches fell by 9% and realtors saw a 40% dip in home sales.

But given that the economy is made up of literally hundreds of products and sectors, it is well within the realm of possibility that the economy did well even while these indicators slowed. For instance, for the same December month, steel output grew by 15%, power generation surged by 6% and refinery output expanded 6.4%. If bank credit slumped, companies doubled their borrowings from the bond market.

Also, CSO estimates do show that some sectors of the economy took it on the chin in the demonetisation quarter. Manufacturing saw its GVA growth slide from 12.8% in Q3 2015 to 8.3% in Q3 2016. Finance, real estate and services saw growth collapse from 10.4% to 3.1%. Construction weakened from 3.2% to 2.7%.

But making up for these was the 6% rebound in agriculture (2.2% shrinkage last year), 6.8% increase in electricity, gas and water supply and a bumper 11.9% hike in ‘public administration, defence and other services’ which lifted the GVA.

Agricultural output bounced back due to a good monsoon after consecutive drought years. Electricity generation was up on better coal availability. ‘Public administration’ reflects higher government payouts on salaries and pensions after the Seventh Pay Commission.

December quarter results from listed companies also provide independent confirmation that the big picture wasn’t much dented by the note ban. A Business Line analysis of over 1,700 listed companies showed that they just reported their best quarterly performance in three years, with sales growing over 9% and profits expanding 20%.

Commentary from listed firms suggests that urban discretionary purchases bounced back quickly as consumers switched to digital payments. Commodity industries, helped by global price rebound, did very well this quarter. In some sectors, business shifted from the unorganised to organised players due to digital payments.

Analysts also suspect that, in some cases, companies mopped up demonetised notes from their distribution channels and pumped them with inventory instead. (This would show up as ‘sales’ in the company’s books and as ‘output’ in GDP estimates).

As the cash situation normalises, these one-offs should get ironed out, moderating GVA growth for the March quarter. But this doesn’t imply that the Q3 GDP numbers are suspect.

Informal left out?


A third criticism of the CSO estimate is that it fails to capture the performance of the informal economy, which clearly bore the brunt of the note ban.

This criticism is partly valid.

Over 40-45% of the Indian economy is informal and hardly any data points relating to it are available at a quarterly frequency. Therefore, what the CSO does to arrive at its quick estimates of the GDP is to take the available data from the organised sector and extrapolate it to infer informal activity. Thus, the GVA for agriculture is guesstimated based on kharif and rabi crop prospects. The GVA for services is inferred from sales tax collections, deposits and credit, telephone connections and so on. Manufacturing GVA uses the index of industrial production and listed company filings.

Owing to such guesswork, it is quite likely that the quarterly GVA estimate, which mainly uses data from the formal sector, painted a rosier picture of growth than the ground reality. But then, if the CSO — with its access to multiple data sources — has no way to estimate the quarterly performance of the informal sector, neither does anyone else.

As long as the CSO consistently follows the same method for measuring the informal sector and publicly discloses it, this is the only estimate we have to gauge economic activity. Both the methodology for estimating informal sector performance and GDP revisions are well-documented and disclosed on the Ministry of Statistics and Programme Implementation website.

More accurate estimates of what really transpired in the Indian economy post-demonetisation will be available when the CSO publishes its first revised GDP estimates, with more ground-level data, in January 2018.

Until then, critics must follow Keynes’s tenet — when facts change, it is best to change your mind.

Water is essential for life on the earth. Precipitation from the skies is the only source for it. India and the rest of Asia are dependent on the monsoons for rains. While the South West Monsoon is the main source for India as a whole, Tamil Nadu and coastal areas of South Andhra Pradesh get the benefit of the North East Monsoon, which is just a less dependable beat on the reversal of the South West Monsoon winds.

SC asks Centre to strike a balance on Rohingya issue (.hindu)

Supreme Court orally indicates that the government should not deport Rohingya “now” as the Centre prevails over it to not record any such views in its formal order, citing “international ramifications”.

The Supreme Court on Friday came close to ordering the government not to deport the Rohingya.

It finally settled on merely observing that a balance should be struck between humanitarian concern for the community and the country's national security and economic interests.

The court was hearing a bunch of petitions, one filed by persons within the Rohingya community, against a proposed move to deport over 40,000 Rohingya refugees. A three-judge Bench, led by Chief Justice of India Dipak Misra, began by orally indicating that the government should not deport Rohingya “now”, but the government prevailed on the court to not pass any formal order, citing “international ramifications”. With this, the status quo continues even though the court gave the community liberty to approach it in …

India’s criminal wastage: over 10 million works under MGNREGA incomplete or abandoned (hindu)

In the last three and half years, the rate of work completion under the Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA) has drastically declined, leading to wastage of public money and leaving villages more prone to drought. This could also be a reason for people moving out of the programme.

At a time when more than one-third of India’s districts are reeling under a drought-like situation due to deficit rainfall, here comes another bad news. The works started under the MGNREGA—close to 80 per cent related to water conservation, irrigation and land development—are increasingly not being completed or in practice, abandoned.

Going by the data (as on October 12) in the Ministry of Rural Development’s website, which tracks progress of MGNREGA through a comprehensive MIS, 10.4 million works have not been completed since April 2014. In the last three and half years, 39.7 million works were started under the programme. Going by the stipulation under the programme, close to 7…
