[Measurement of Inequality]

 The concept of inequality and its measurement plays an important role in both positive and normative economic analysis. In its positive aspect, it is important to understand the magnitude and profile of any problem like poverty, inequality and food insecurity across states/countries not only at a point of time but also for over time particularly in the course of economic development. As already seen under Topic 3, FAO provides estimates of the prevalence of undernourishment across countries with reference to estimates of per capita dietary energy supply, mean energy requirement and inequality in distribution of access to calories. Hence, it is very important to know the concept of inequality, its theoretical welfare properties and policy implications. Its normative dimensions are important particularly in the context of polices on taxes and subsidies.
 The session begins with a distinction between absolute and relative income/consumption/calorie distributions. As regards inequality measurement, normative and positive measures are distinguished with illustrations. The consequences of redistributive policy instruments are assessed in terms of estimates of inequality measures before- and after-policy change. Methods for estimating inequality measures are illustrated with reference to the Indian experience of strategies for economic growth with redistribution, and their fallacies.
