Income-Related Inequalities in Future Health Prospects

Area of Science:

• Health Economics
• Public Health Policy
• Health Disparities Research

Background:

• Monitoring health systems relies on measuring health disparities.
• Existing measures often neglect individual health risk and future health prospects.
• Income-related health inequality is a critical area for public health intervention.

Purpose of the Study:

• To integrate individual health risk into the measurement of income-related health inequality.
• To develop a novel rank-dependent health inequality index accounting for expected and dispersed future health.
• To assess the impact of considering individual risk on estimating health disparities.

Main Methods:

• Development of a rank-dependent health inequality index.
• Incorporation of individual expected future health and its dispersion.
• Empirical analysis using Australian longitudinal health and income data.

Main Results:

• Neglecting individual health risk leads to an underestimation of income-related health inequalities.
• The poor face not only worse expected future health but also greater dispersion in health prospects.
• The proposed index reveals more significant health inequalities when individual risk is considered.

Conclusions:

• Accurate measurement of health disparities requires incorporating individual health risk.
• Social planners should consider risk-averse preferences when assessing health inequalities.
• Policy interventions targeting health disparities must address both expected health outcomes and risk exposure.
