The finance ministry on Friday sought to underplay GDP growth overestimates due to a \u201cblack hole\u201d in the MCA database used for the computation of national income. It said only 16.4% of the companies in the database of service-sector firms are either closed or non-traceable, against 38.7% reported by sections of media, citing the latest report of the National Sample Survey Organisation. If one takes the paid-up capital of such elusive firms, then their share in the database was even lower at between 12-15% in the five-year period through FY17. The ministry also argued that the blowing up (of data) anyway doesn\u2019t materially affect the year-to-year GDP growth, as much as the level of GDP. However, an analysis of some 3,000 non-financial and non-government listed firms tracked by the Reserve Bank of India shows a stark difference between their profitability and the growth in gross value added (GVA) in manufacturing as well as services segments under the new GDP series in recent years (see the chart). Read | Don\u2019t politicise MCA data, says Sanjeev Sanyal; GDP calculation always troublesome but better than before Manufacturing and services segments constitute the likes of \u201cconstruction\u201d and \u201ctrade, hotels, transport, communication and services related to broadcasting\u201d. The MCA21 data, relied on for calculations of the national income, had 5.6-7.1 lakh companies between FY13 and FY17. However, the difference of growth rates of these two key indicators was still starker in the UPA years (FY13 and FY14). \u201cOf the 38.7% (out-of-survey) enterprises, out-of-coverage enterprises comprise 21.4% (and these) are engaged in some economic activity, possibly in the manufacturing sector,\u201d the ministry noted. Of the remaining 17.3% out-of-survey enterprises, those not in the MCA database for GDP estimation comprise 0.9%, so only the balance 16.4% are closed\/non-traceable ones, it added. Since the proportion of such defunct\/elusive firms in the database is falling, the ministry noted, \u201cthe extent of overestimation of GDP in all likelihood is marginal\u201d.

Accordingly, their inclusion in the overall GVA estimation was legitimate,\u201d the ministry asserted. The proportion of firms in the MCA data base that have ceased their operations varies minimally from year to year from 2012-13 to 2016-17. \u201cThis feature ensures that although GVA levels could be slightly more or less than what they actually are, the growth rate of GVA from year to year will not be affected,\u201d it said. \u201cThe MCA data base on the private corporate sector is a valuable addition to the data sources available for estimation of GDP and its use provides a more correct measure of economic activity in the country,\u201d the ministry concluded.
