___ Sonsider the six-person weekly income distribution of a country X = (170, 305, 300, 325, 700, 750). The country has two regions: Region | and Region II. The income distributions of these two regions are Xi = (170, 305) and Xn = (300. 700. 325, 750). Over time. the income distribution of Region | changes to Y. = (185. 240) while the income distribution of Region II changes to Yu = (315, 750, 325, 800). Suppose the weekly poverty line income is z = 350. a Compute the headcount ratios, poverty gap measures and squared poverty gap measures for the country and for both regions in both periods. b. Employing the additive decomposability property of poverty. show how the contributions of each region has changed over time for all three measures.
