An efficient employer strategy for dealing with adverse selection in multiple-plan offerings: an MSA example

Area of Science:

• Health Economics
• Insurance Policy Analysis

Background:

• Adverse selection and inefficiency arise when limited and generous insurance policies are offered concurrently.
• Employee premium contribution policies can mitigate these issues.

Purpose of the Study:

• To define and evaluate an "efficient premium contribution" policy.
• To assess the impact of adding a catastrophic health plan (CHP) with a medical savings account (MSA) option.
• To analyze efficiency gains and distributional consequences, particularly for high-risk individuals.

Main Methods:

• Theoretical outlining of a feasible employee premium contribution policy.
• Definition and analysis of "efficient premium contribution" for risk-based allocation.
• Simulation modeling of an MSA/CHP option alongside existing insurance plans.

Main Results:

• The proposed efficient premium contribution policy leads to efficient allocation across plans based on risk.
• This policy may result in redistribution away from higher-risk individuals.
• The addition of an MSA/CHP option yields positive but small efficiency gains.
• Adverse consequences for high-risk individuals under the efficient premium policy are minimal.

Conclusions:

• An efficient employee premium contribution policy is a feasible approach to reduce insurance market inefficiencies.
• The introduction of MSA/CHP options can enhance efficiency without significant adverse effects on high-risk groups.
• Policy design should consider both efficiency and equity implications for different risk profiles.
