Validating India's GDP Growth Estimates
CID Faculty Working Paper No. 357

July 2019
My recent research paper “India's GDP Mis-estimation: Likelihood, Magnitudes, Mechanisms, and Implications,” (hereafter “GDP paper”) and the associated op-ed in the Indian Express on June 11, 2019 have generated considerable debate. This is encouraging because serious argument and counter-argument are the basis for good policy-making. Since the issue itself is of great importance, the counter-arguments to my analysis warrant a considered response. That is the aim of this note, which is a complement to the original paper, addressing both the larger issues and some of the specific points that have been raised.
The note is structured as follows. Section II describes my engagement with India’s GDP estimation when I was Chief Economic Adviser. Section III elaborates on the framework/approach underlying the GDP paper. Section IV makes explicit the key puzzle surrounding India’s growth estimates, and addresses the possible explanations for it. Section V explores the puzzle in greater detail. Section VI provides additional cross-country evidence on growth and price deflators, which support the findings of the original paper, namely that growth during 2011-16 was likely overestimated by a significant margin. Section VII addresses two broad objections to the main findings. Section VIII discusses some of the methodological critiques of the paper. Section IX offers some thoughts on the way forward.
