Geographic Decomposition Of Inequality In Health And Wealth: Evidence From Cambodia, Tomoki Fujii Sep 2013

Geographic Decomposition Of Inequality In Health And Wealth: Evidence From Cambodia, Tomoki Fujii

Research Collection School Of Economics

Applying the small-area estimation methods to Cambodia data, we decompose the total inequality in wealth (consumption) and health (child undernutrition) indicators into within-location and between-location components. Because the knowledge of the pattern of spatial disparity in poverty and undernutrition is important for the geographic targeting of resources, we conduct a geographic decomposition of the variance of the Foster-Greere-Thorbecke index in addition to the standard decomposition exercise based on the generalized entropy measures. We find that a sizable proportion of wealth inequality is due to between-location inequality, whereas health inequality is mainly due to within-location inequality.

Geographic Decomposition Of Inequality In Health And Wealth: Evidence From Cambodia, Tomoki Fujii

Research Collection School Of Economics

The small-area estimation developed by Elbers, Lanjouw and Lanjouw (2002, 2003), in which a census and a survey are combined to produce the estimates of welfare measures for small geographic areas, has become a standard tool for poverty analysis in developing countries. The small-area estimates are typically plotted on a map, which are commonly called a poverty map. Poverty maps proved useful for policy analysis and formulation, and have become increasingly popular among policy-makers and researchers. In Cambodia, poverty maps have been used by various international organizations, ministries and non-governmental organizations for analyzing the poverty situations for their operation areas, …


The Consequences Of A Public Health Insurance Option: Evidence From Medicare Part D Prescription Drug Markets, Daniel P. Miller, Jungwon Yeo Jul 2013

The Consequences Of A Public Health Insurance Option: Evidence From Medicare Part D Prescription Drug Markets, Daniel P. Miller, Jungwon Yeo

Research Collection School Of Economics

This paper examines a public option competing alongside private insurers in Medicare Part D. We estimate a random coefficient demand system and oligopoly supply-side model with endogenous premium subsidies and risk adjustment payments. If the public option does not affect health risk sorting, counterfactual results show modest competitive benefits. However, increased subsidy payments eliminate welfare gains regardless of the public option's cost position. If the public option adversely selects -- facilitating insurers' ability to cream-skim favorable risk -- the risk adjustment mechanism creates a downward pricing distortion, amplifying competitive benefits. Despite greater selection, total surplus may increase, but the division …
