Inequality and fairness with heterogeneous endowments

Area of Science:

• Social Psychology
• Behavioral Economics
• Sociology

Background:

• Individuals possess diverse inherited characteristics (e.g., intelligence, personality) influencing success.
• Understanding how individual heterogeneity impacts fair distribution of rewards and outcomes is a key societal question.

Purpose of the Study:

• To theoretically develop and experimentally test conditions under which individual differences lead to fair distributions of rewards.
• To distinguish between various fairness concepts: meritocracy, equality of opportunity, equality of outcomes, and Rawls's theory of justice.

Main Methods:

• Theoretical framework development to analyze functional relationships between individual endowments and outcomes.
• Online experiment involving differently endowed individuals sharing resources.
• Varying information availability regarding others' endowments and outcomes.

Main Results:

• Visible outcomes reduce outcome inequality by decreasing statistical dispersion within groups.
• Visibility of individual endowments is essential for improving equality of opportunity, particularly for the most disadvantaged.

Conclusions:

• Fairness perceptions and emergent distribution patterns are contingent on information visibility.
• Policy and social structures should consider endowment visibility to promote genuine equality of opportunity.
