Redistributional consequences of community rating

Area of Science:

• Health economics
• Public health policy
• Insurance market analysis

Background:

• Community rating aims to standardize health insurance premiums.
• Geographical variations in healthcare costs and utilization exist.
• The impact of community rating on different socioeconomic and geographic groups requires investigation.

Purpose of the Study:

• To predict the geographical effects of community rating on health insurance premiums.
• To analyze the financial impact on individuals based on location and socioeconomic status.
• To identify potential wealth transfers between communities due to rating policies.

Main Methods:

• Utilized a 5% sample of Californians from the 1990 U.S. Census (Public Use Microdata Sample).
• Employed an episodic health simulation model to estimate health expenditures for over 975,000 individuals.
• Adjusted simulated expenditures for regional price variations by county to estimate community-rated premiums.

Main Results:

• A single, state-wide premium resulted in rural residents paying more than their healthcare use, while urban residents paid less.
• Significant wealth transfers were observed from poorer, rural communities to wealthier, urban communities.
• Even regional risk pooling at the county level still showed subsidies flowing from poorer to wealthier areas.

Conclusions:

• Mandated community rating in heterogeneous states like California leads to substantial, unintended wealth redistribution.
• Allowing premiums to reflect regional medical care costs can reduce these transfers.
• Targeted subsidies for low-income families can effectively mitigate the regressive consequences of geographic community rating.
