5. Introduction This paper examines the impact of fiscal policy on poverty through changes in distribution. This does not take into account the impact of fiscal policy on growth. This study captures only first order effects.

6. Poverty Measures : Headcount ratio : Poverty gap : Severity of poverty A class of additive separable poverty measures:

7. Growth Elasticity of Poverty - Growth elasticity of poverty: the elasticity of  with respect to  when L(p) remains constant. - Growth elasticity of poverty for FGT measures: which is always negative. < 0

8. Growth Elasticity of Income Components - x is the disposable income and g i (x) is the ith income received by an individual with disposable income x. - For FGT, the ith income component elasticity is defined as - if all income components grow at the same rate of 1%, then the total poverty will change by

9. Pro-poor Index of the Income Components = Income effect + Distribution effect -If the distribution effect is negative (positive), the redistribution effect of the ith income component reduces (increases) poverty, implying that the ith income component is pro-poor (anti-poor) - Pro-Poor Index for ith income component is:

10. Indirect Taxes and Subsidies - Indirect taxes and subsidies have direct impacts on prices. - Elasticity of poverty with respect to p i is

11. Pro-Poor Index for Prices - Elasticity of poverty with respect to p i can be decomposed into = Income effect + Inequality effect -Inequality effect: whether an increase in p i hurts the poor proportionally more than the non-poor. -If inequality effect > 0, the increase in p i hurts the poor proportionally more than the non-poor

12. Pro-Poor Index for Prices Pro-Poor Index for price is defined as - If the index is greater (less) than 1, an increase in p i hurts the poor more (less) than the non-poor. - If the index is greater than 1, then the ith commodity should be subsidized so that the poor benefit more relative to the non-poor. - If the index is less than 1, taxing the ith commodity will hurt the rich more than the poor. -The index can be used as a tool to improve the tax or subsidy schemes to maximize poverty reduction.

13. Fiscal Structure in Thailand -Thailand’s fiscal system is highly centralized. -Centralized fiscal system contributes to the unequal distribution of public services, e.g. public infrastructure, education, health, etc.
