Can institutions foster cooperation by wealth redistribution?

Area of Science:

• Evolutionary Game Theory
• Institutional Economics
• Behavioral Economics

Background:

• Theoretical models suggest institutions can enforce cooperation via punishments/rewards.
• Real-world institutions often lack sophistication or may act selfishly, exploiting populations.

Purpose of the Study:

• To analyze the evolution of cooperation under an autonomous institution with its own interests.
• To investigate how institutions with varying goals (prosocial, cooperator-focused, selfish) impact cooperation.

Main Methods:

• Agent-based modeling or game-theoretic analysis of an autonomous institution.
• Simulating an institution that taxes a population and redistributes revenue to cooperators.
• Analyzing institutional utility functions to determine taxation and redistribution strategies.

Main Results:

• Prosocial institutions promote cooperation if sufficiently forward-looking.
• Institutions maximizing cooperator welfare ensure cooperation even if myopic.
• Selfish institutions can also promote cooperation; increased foresight benefits the population, sometimes exceeding anarchy.

Conclusions:

• Institutional wealth redistribution can benefit populations, even when institutional interests diverge.
• The forward-looking nature of an institution significantly influences its ability to promote cooperation.
• Autonomous institutions, regardless of their specific goals, can play a role in fostering cooperative behaviors.
