Poverty remains one of the most pressing issues of our time. Understanding the impact of macroeconomic policy on poverty through growth and distribution of income is of considerable interest and this is what I examine in this dissertation. In Chapter 1, 'The Arithmetic of the Poverty-Growth- Inequality Triangle-Evidence from States of India', I use an arithmetic approach to examine how growth and income distribution matter simultaneously to poverty reduction by separating changes in poverty into a growth and distribution component. The results indicate that the poor benefit more from increasing aggregate growth than reducing inequality. In fact, bulk of the poverty reduction is concentrated in a period which witnessed the steepest increase in inequality since the effect of growth on poverty was large enough to overturn the effect of adverse distributional changes. Also, there is a great deal of heterogeneity in the poverty reduction performances of states, in particular the growth elasticity of poverty. I examine this heterogeneity in Chapter 2, 'The Empirics of the Poverty-Growth-Inequality Triangle: Does High Initial Poverty Matter?- Evidence from Rural India'. The more equal the initial income distribution and the higher the initial level of development, the greater is the growth elasticity of poverty. This empirical analysis also examines the impact of initial poverty on the pace of poverty reduction via its impact on economic growth and growth elasticity of poverty. Initial poverty has no adverse impact on growth; however it may lower the growth elasticity of poverty slightly. Furthermore, I find evidence of poverty convergence. In Chapter 3, 'Fiscal Policy and Macroeconomic Stabilility: Automatic Stabilizers Work, Always and Everywhere', I examine what can be done to protect the poor from macroeconomic shocks and volatility. Developed countries have in place in-built Counter cyclical automatic stabilizers to protect the poor from macroeconomic shocks and volatility and there is a vast literature on their effectiveness in reducing output volatility. Their effectiveness in developing countries has not been empirically validated. Using a sample of 49 countries, we estimate the impact of automatic stabilizers on output volatility and find that they strongly contribute to output stability regardless of the type of economy.
