Physician response to fee changes with multiple payers

Area of Science:

• Health Economics
• Physician Behavior Modeling
• Healthcare Policy

Background:

• Physician behavior significantly impacts healthcare costs and service delivery.
• Existing models often simplify physician motivations, neglecting nuanced economic drivers like demand inducement.
• Understanding how physicians respond to fee adjustments is vital for healthcare policy and market dynamics.

Purpose of the Study:

• To develop a general model of physician behavior incorporating demand inducement.
• To analyze physician responses to fee changes under different behavioral assumptions (profit maximization vs. target income).
• To explore the implications for healthcare fee policies and empirical research.

Main Methods:

• Development of a general theoretical model of physician behavior.
• Analysis of physician responses to fee changes using derived own and cross-price expressions.
• Consideration of scenarios with multiple payers and varying income effects.

Main Results:

• Physicians exhibit profit maximization behavior when income effects are absent.
• Physicians aim for a target income when income effects are strong.
• The model provides distinct predictions for physician responses to fee changes based on their underlying behavior.

Conclusions:

• Physician behavior is not monolithic and depends on economic factors like income effects.
• Fee policies must account for different physician motivations to be effective.
• The developed model offers a more realistic framework for studying physician responses to economic incentives in healthcare.
