Formal risk adjustment by private employers

Area of Science:

• Health Economics
• Market Dynamics
• Healthcare Policy

Background:

• Private employers exhibit low adoption rates of formal risk adjustment mechanisms.
• Existing explanations, such as data scarcity or imperfect signals, are insufficient to explain this trend.
• The healthcare market's dynamic nature and lack of equilibrium are central to understanding adoption patterns.

Purpose of the Study:

• To investigate the underlying reasons for the limited adoption of formal risk adjustment by private employers.
• To evaluate the adequacy of conventional explanations for low adoption rates.
• To propose an alternative framework based on market dynamics and evolving demand.

Main Methods:

• Qualitative analysis of market factors influencing risk adjustment adoption.
• Review of economic theories related to market equilibrium and agent behavior.
• Examination of demand-side drivers for risk adjustment implementation.

Main Results:

• Lack of data, imperfect signals, and absence of market power do not fully explain low adoption.
• Alternative strategies to mitigate selection issues are recognized as important.
• The primary driver identified is the non-equilibrium state of U.S. health markets.
• Current low demand from key stakeholders (consumers, employers, plans, providers) contributes to slow uptake.

Conclusions:

• The slow adoption of formal risk adjustment by private employers is primarily attributed to the rapidly changing, non-equilibrium state of U.S. health markets.
• A lack of current demand from various market agents explains the limited uptake.
• Anticipated changes in health plan markets may increase demand and accelerate future adoption of risk adjustment.
