A note on eliciting distributive preferences for health.

Area of Science:

• Health Economics
• Public Health Policy
• Behavioral Economics

Background:

• Quantifying health equity preferences is theoretically possible via an 'inequality aversion parameter'.
• Empirical elicitation of these preferences faces significant methodological challenges.
• Existing models of the equity-efficiency trade-off may not fully capture real-world choices.

Purpose of the Study:

• Investigate the types of preferences influencing choices in equity-efficiency trade-off scenarios.
• Identify factors beyond pure equity aversion that shape distributive preferences for health gains.
• Provide practical insights from a survey designed to elicit health gain distributive preferences.

Main Methods:

• Analysis of respondent choices in hypothetical health gain distribution scenarios.
• Identification of potential confounding factors influencing decision-making.
• Qualitative and quantitative assessment of survey responses.

Main Results:

• Respondent choices can be influenced by factors unrelated to equity preferences.
• A 'threshold effect' may explain preferences for concentrating health gains over diffusing them.
• Survey data revealed complexities in translating theoretical 'inequality aversion' into practical choices.

Conclusions:

• Methodological challenges persist in empirically measuring health equity preferences.
• Non-equity related concerns, such as threshold effects, significantly impact distributive choices.
• Survey design for eliciting distributive preferences requires careful consideration of behavioral influences.
