Growth convergence and regional inequality in India (1981-2012)

Abstract

There has been significant research effort to study the impact of liberalisation on growth and distribution in India. Using per capita income (PCI) data for the period 1981-82 to 2012-13 (28 regions for the entire period and 31 regions for 2001-2 to 2012-13) at the sub-national level in India we examine the claims of divergence and stratification (twin peak formation) as has been claimed in some of the recent literature. We confirm that there is divergence of PCI. We present the first set of tests of multimodality in the Indian convergence debate using Silverman (J R Stat Soc 43:97-99, 1981; Density estimation for statistics and data analysis. Monographs on statistics and applied probability, Chapman & Hall, London, 1986) procedure. Weighted kernel density plots and multi-modal tests reveal that there is emergence of "multi-modes" in the distribution of PCI, not just twin modes. The spatial pattern of growth reflects an area of stagnation in the eastern-central belt—Bihar, Madhya Pradesh, Uttar Pradesh and Orissa, and in the north eastern part of India—Assam and Manipur and a decline in Mizoram. Sikkim demonstrates fastest growth, whereas Gujarat, Haryana, Kerala, Maharashtra, Punjab, Tamil Nadu (among the big states) and Himachal Pradesh, and Andaman and Nicobar (small state and Union Territories) maintained their position. Karnataka, and Andhra Pradesh (among the southern states), Arunachal Pradesh and Nagaland (among the north eastern states) along with Jammu and Kashmir, Uttarakhand and Chhattisgarh, moved up in the growth ladder. The continuation of growth stagnation in most of the BIMARU states poses a challenge to received theories of growth convergence and raises developmental concerns that the increased play of market forces in the Indian economy have not been able to overcome.
