Health Care Expenditure and Income: A Global Perspective

Area of Science:

• Health Economics
• Econometrics
• Development Economics

Background:

• Healthcare expenditure and income are key indicators of societal well-being and economic development.
• Understanding the long-run relationship between these variables is crucial for policy-making and resource allocation.

Purpose of the Study:

• To investigate the long-run economic relationship between healthcare expenditure and income globally.
• To analyze income elasticity of healthcare expenditure across different country income groups and geopolitical areas.

Main Methods:

• Utilized panel data methods for 167 countries (1995-2012) from the World Bank dataset.
• Employed models accounting for unobserved heterogeneity, temporal persistence, and cross-section dependence (common factor or spatial process).
• Estimated global and sub-sample income elasticities.

Main Results:

• Globally, healthcare expenditure is found to be a necessity, not a luxury good.
• Significant variations in income elasticity were observed across different sub-samples.
• Poorer countries exhibit higher income elasticity, indicating greater responsiveness of healthcare spending to income changes.

Conclusions:

• The relationship between healthcare expenditure and income is complex and context-dependent.
• Policy interventions may need to be tailored based on a country's position in the global income distribution.
• Findings underscore the essential nature of healthcare while highlighting disparities in its economic relationship with income.
