Understanding growth slowdown dynamics in India’s sub-national economies

Purpose - The paper offers the first systematic and comprehensive analysis of dynamics of economic growth slowdown for India at the sub-national level covering the period 1993–2013. In light of India’s regional diversity and variation in terms of gross regional domestic product (GRDP) per capita, the purpose of this paper is to empirically investigate the growth dynamics at the sub-national level. The paper aims to answer two questions: first, are determinants of economic slowdown likely to differ across income groups? Second, what are the probabilities that the sub-national economies in India will experience a growth slowdown in the near future? Design/methodology/approach - The paper undertakes a comprehensive analysis of growth slowdown for 106 Asian developing economies encompassing the national economies in ASEAN and the sub-national economies in Greater China, Indonesia and India. To be sure, the authors are not making any direct comparison to countries at different stages of economic development; rather, the comparison is between economies/sub-national economies that fall in the same income category. The authors construct income group-specific logistic model to identify the relevant determinants of growth slowdown and use Bayesian model averaging techniques as a robustness check. The authors also compute economy-specific predictive probabilities of growth slowdown over the period 2012–2017. Findings - The empirical results show that a growth slowdown in various income groups tends to be associated with different sets of determinants, although broadly, across all income groups, the occurrence of growth slowdown is positively associated with higher GRDP per capita. The average predictive probability of growth slowdown for India’s sub-national economies is 0.43, indicating that, on average, India’s sub-national economies have a 43 per cent chance of experiencing growth slowdown in the 2012–2017 period. Overall, the prospects of the sub-national economies of India are less worrying than that of Greater Chinese economies but bleaker than the outlook for economies in ASEAN and Indonesia. Originality/value - The research contributes to the understandings of growth dynamics, especially the issue of growth slowdown, in India. This paper differs from the existing literature on growth dynamics by being India centric and analysing the issue of growth slowdown at the sub-national level. Despite a steady increase in the level of GRDP per capita for the sub-national economies of India since 1993, significant disparities still exist across economies. Identifying determinants of growth slowdown and subsequently computing predictive probabilities serves as early warning signs for policy-makers and generates insights on how development policy can be shaped.
