Abstract

In this paper, we discuss some of the methodological issues involved in the computation of value addition in the manufacturing sector. We deal with (i) problems of blow-up of estimates (ii) choice of indicators in measuring output, and (iii) a possible misclassification of companies in the MCA21 database that can distort the GVA estimates. A sample based blow-up exercise shows that Paid-Up Capital and GVA contribution of firms have no one-to-one correspondence and the method can lead to overestimation of value addition. We construct an alternate method of blow-up by using representative industry GVA growth rates to scale up previous GVA estimates to account for data of unavailable companies. We show that a potential misclassification of companies in the MCA21 can also lead to significant distortion in GVA estimates.
