How to Select the Leader in a One-Shot Public Goods Game: Evidence from the Laboratory

Area of Science:

• Behavioral Economics
• Experimental Economics
• Game Theory

Background:

• Public goods provision is crucial for societal well-being.
• Understanding factors influencing cooperation is essential for effective resource management.
• Leadership selection mechanisms can potentially impact group behavior and outcomes.

Purpose of the Study:

• To experimentally investigate the impact of different leadership selection mechanisms on public goods provision.
• To identify which leadership structures foster or hinder cooperative behavior in groups.
• To evaluate the effectiveness of endogenous versus exogenous leadership selection.

Main Methods:

• Conducting controlled laboratory experiments with human participants.
• Implementing various leadership selection protocols (e.g., voluntary, random selection).
• Measuring individual contribution levels to a public good under different leadership conditions.

Main Results:

• Introducing leadership did not significantly increase overall contributions to the public good.
• Voluntary leadership selection resulted in the lowest contribution levels.
• Random selection of voluntary leaders emerged as a promising mechanism, signaling cooperative intent and mitigating free-riding.

Conclusions:

• Leadership introduction alone does not guarantee improved public goods provision.
• The method of leadership selection is critical; voluntary selection can be counterproductive.
• Endogenous leadership selection, particularly through random assignment of voluntary candidates, can effectively promote cooperation by signaling commitment and reducing free-riding incentives.
