Background:

• Analyze beneficiary and plan behavior under current Medicare policies.

Main Methods:

• Analysis of beneficiary choices using behavioral economics principles.
• Assessment of Medicare plan design and market functioning.
• Evaluation of Medicare's risk adjustment and premium policies impact.

Main Results:

• Beneficiary choices often reflect behavioral biases, not purely economic efficiency.

Conclusions:

• Updated Medicare policies (e.g., risk adjustment) have successfully addressed adverse selection.
• Medicare Advantage plans offer superior value compared to traditional Medicare.
• Reforms in beneficiary cost-sharing for Medicare Advantage are recommended to boost enrollment and efficiency.
