An Empirical Verification of Kuznets Hypothesis in India

The trajectory of output growth, more precisely economic growth and its interaction with other phenomena of an economy follows a complex path. Among many phenomena the one that has caught the world attention at large scale especially since the work of Piketty and Saez is the “Rising Inequality in Incomes”. Though for some countries like India there was a reduction in the poverty level, there seems no positive bearing on economic growth in improving income distribution for past two decades. In this paper, we have used ARDL cointegration approach to analyze the relationship between income inequality (EHII, from UTIP-UNIDO) and its various determinants from 1964 to 2007. Besides using data on Estimated Household Income Inequality (EHII), we have used income share of top 1% as an alternative measure of inequality. Our results reveal no relevance of Kuznets Hypothesis, instead, the relationship is U-shaped in nature, implying that with the initial rise in GDP per capita inequality decreases, later on as GDP increases, inequality tends to increase. Among the control variables, CPI (price level) is found to be positively and Government expenditure negatively related to inequality, while trade openness showed no significant relationship.
