A major problem that India faces is the large cross-sectional dispersion in economic development. There is a roughly 3:1 ratio in the per capita GDP, when we compare the richest states to the poorest states. In Bihar, Orissa, Assam and Uttar Pradesh—these make up 33.9% of India’s population—per capita SDP was over 33% below the national average. Regional disparities in India have been present for at least a century, if not more. Under normal circumstances, the processes of the market economy should generate ‘‘equalising differences,’’ whereby firms move to low-wage areas in the quest for reduced costs thus equalising differences in wages and land prices. Similarly, individuals migrate to high-wage areas, thus equalising wages, and increasing the land per capita in poor areas. These processes are expected to generate convergence of per capita GDP in the normal framework of growth theory. (But) From the empirical evidence of the 1990s, there is some evidence of a lack of convergence. Some states, particularly the states of the West and the South, seem to have excelled in harnessing the opportunities of globalisation and the market economy. In other states, weaknesses in human capital and governance have generated reduced growth rates in the post-1990 period. This has been a source of much concern on the part of many observers, from two points of view. First, it is argued that if the economic reforms of the 1980s and 1990s failed to ignite growth in Bihar, then there is a need to find a new policy mix which can achieve high growth in Bihar. Second, there are fears of mounting political stress that might come about if income disparities between rich and poor states widen further. There is a remarkable similarity between these problems in India and those that have been observed in China, where coastal provinces have progressed enormously compared with the interior. While the above difficulties are real, there are also many forces at work which are steadily having an ameliorating effect. • Flexibility of the labour market: As of today, roughly 90% of India’s labour force is in the unorganised sector, which is a classical labour market, undistorted by labour law. In addition, unlike China, India has no government restrictions on inter-state or rural-to-urban migration. This innate flexibility of the labour market will assist the process of convergence. • Impact of new infrastructure on ‘‘equalising differences’’: Gains from internal trade are clearly an important mechanism through which poor states can obtain economic growth. This is critically related to costs of transportation. This suggests that the recent successes in infrastructure policy—particularly in roads, ports, airports, and telecom—are highly significant in thinking about regional disparities. • Fiscal transfers: India has a well-developed system of fiscal transfers, through which taxes collected in rich states are transferred to poor states. This constitutes an important channel for convergence. While these rules have always been with us, the economic significance of these transfers improves in line with growth in GDP and in the tax/GDP ratio. In the decade of the 1990s, India’s GDP was roughly $350 billion and the tax/GDP ratio was roughly 12%. GDP has already risen to $620 billion, giving a quantum leap in the expenditures of government. Looking forward, in a few years, if we envision GDP of $1 trillion and a tax/GDP ratio of 15%, then there will be enormously larger resource flows through existing fiscal institutions, which will generate much larger spending in poor states. • Policy innovations: One important insight derived from the experience of economic growth in East Asia is the importance of ‘‘regional role models’’ where countries learned from each other. In the decade of the 1990s, a similar phenomenon has begun with the states. The political leadership of many states is increasingly conscious of the need to find policy innovations which would improve the quality and quantity of local public goods. Andhra Pradesh, Madhya Pradesh, West Bengal, and Kerala are all examples of states where there has been a distinct learning from the regional role models, and consequent changes in governance.
