Effect of Peer Punishment on Contributions in Melbourne's Public Good Game Experiment

In a series of experiments involving a group investment game, a mechanism was introduced allowing participants to anonymously pay a small fee to impose a larger financial penalty on others in their group. The results varied by location. In some groups, cooperation levels started high and did not decline over time. In other groups, cooperation started low but steadily increased with each round. Which statement best analyzes this difference in outcomes?

Based on the findings from a large-scale, multi-location group investment experiment, the introduction of a costly punishment option had a uniform effect across all participating groups, consistently causing a dramatic increase in contributions from initially low levels.

Explaining the Efficacy of Peer Punishment

In a large-scale experiment, participants played a group investment game where they could anonymously pay a small fee to impose a larger financial penalty on others. The results showed this punishment option affected cooperation differently across various locations. Match each described experimental outcome with its correct classification.

Predicting Policy Outcomes from Experimental Data

In a group investment game experiment where costly punishment was an option, participants in City A maintained a high level of contribution across all rounds. In contrast, participants in City B started with low contributions, which then steadily rose over the course of the experiment. The outcome in City A demonstrates that the mere threat of punishment can be sufficient to prevent a _______.

Evaluating Community Contribution Strategies

Two communities are trying to crowdfund a local park. Community A has a strong history of successful group projects. Community B has a history of similar projects failing due to low participation. Both communities introduce a new rule: after contributions are revealed, members can anonymously pay a small fee to impose a larger financial penalty on any other member. Based on findings from large-scale experiments on group cooperation, which of the following outcomes is the most plausible judgment of the new rule's effectiveness?
