Predicted Outcome with Self-Interested Players in the Worldwide Public Good Game
Based on the assumption that all participants are motivated solely by self-interest, the predicted outcome for the worldwide public good game is universal free-riding. In this scenario, every player would logically choose not to contribute any money to the common pool.

Predicted Outcome with Self-Interested Players in the Worldwide Public Good Game
Figure 4.14a: Deciding on a Contribution in the Worldwide Public Good Game
Imagine you are in a four-person group where each person, including you, is given $20 for a single round. You can contribute any amount of this $20 to a group project. For every $1 contributed to the project by any member, every person in the group (including those who did not contribute) receives a return of $0.40. Any money you do not contribute, you keep. You have a strong belief that the other three members of your group will each contribute exactly $10. To maximize your own personal financial payoff, what is the best action for you to take and what will your final payoff be?
Analyzing a Player's Decision in a Public Good Scenario
Consider a one-round scenario where four individuals are each given $20. They can secretly contribute any amount to a group project. For every $1 contributed to the project by anyone, each of the four individuals receives a return of $0.40. A player who wants to maximize their personal financial gain should contribute an amount equal to what they expect the other three players to contribute on average.
Explaining the Free-Rider Incentive
You are a participant in a four-person group activity. Each person is given $20. For every $1 contributed to a group fund by any member, every person in the group (including the contributor) receives $0.40. Assume the other three members contribute a total of $30 to the fund. Match each of your potential contribution choices with your correct final personal payoff.
Analyzing the Conflict Between Individual and Group Interests in a Public Goods Scenario
In a four-person public goods scenario, each person starts with $20. For every $1 contributed to a common pool, each of the four members receives $0.40. If the other three members contribute a total of $30, your personal payoff will be exactly $____ more if you contribute $0 than if you contribute your full $20.
A rational, self-interested player is participating in a one-round, four-person activity. Each person is given $20. For every $1 contributed to a group fund, every person in the group receives $0.40. Arrange the following steps in the logical order that the player would follow to decide their optimal contribution.
A participant in a four-person group activity is given $20. For every $1 contributed to a group fund by any member, every person in the group receives $0.40. The participant reasons: 'If all four of us contribute our full $20, the total fund will be $80. My personal return will be $80 × $0.40 = $32. Since $32 is more than the $20 I started with, it is in my personal financial interest to contribute my full $20, as long as everyone else does too.' From the perspective of maximizing one's own individual payoff, what is the primary flaw in this participant's reasoning?
A participant is in a four-person group activity that lasts for several rounds. In each round, every person is given $20 and can contribute to a group fund. For every $1 in the fund, each of the four members receives $0.40. After each round, all participants are told how much the other three members contributed. In Round 1, this participant contributes $10. In Round 2, after seeing that the other three members contributed a total of only $5 between them, the participant contributes $0. Which of the following best analyzes the participant's decision to contribute $0 in Round 2 from a purely self-interested financial perspective?
Learn After
In an economic experiment, four participants are each given an initial sum of money. They can secretly choose to contribute any portion of this money to a group project. The total amount contributed to the project is then doubled by the experimenter and distributed equally among all four participants, regardless of their individual contributions. If every participant's sole motivation is to maximize their own personal financial gain, what will be the total amount of money contributed to the group project?

Predicting Behavior in a Group Investment Scenario
In a one-shot public goods game where all participants are assumed to be perfectly rational and motivated only by maximizing their own financial gain, the predicted outcome is that a small, but non-zero, amount will be contributed to the public pool to ensure at least some collective benefit is generated.

Analyzing Rational Decision-Making in a Group Investment Scenario
Imagine a one-time economic game with 10 participants. Each is given $100 and can secretly contribute any amount to a central pot. The total money in the pot will be doubled and then divided equally among all 10 participants, regardless of their individual contributions. Assume every participant is perfectly rational and aims only to maximize their own personal financial gain. Which of the following statements best analyzes the stability of a potential outcome where every participant contributes their full $100?
Four individuals participate in a one-time economic experiment. Each is given $20 and can secretly contribute any amount to a group fund. The total amount in the fund is then doubled and distributed equally among all four participants, regardless of their individual contributions. Assume every participant is motivated solely by maximizing their own personal financial gain.
Consider two potential outcomes:
- Outcome A: All four individuals contribute their full $20.
- Outcome B: Three individuals contribute their full $20, but one individual contributes $0.
Which statement correctly analyzes the financial position of the individual who contributes $0 in Outcome B?
In a one-time economic game, a group of individuals can contribute to a public project. Any contributions are multiplied and then distributed equally among all members, regardless of who contributed. If every individual acts solely to maximize their personal financial outcome, the predicted result is that no one will contribute. From the perspective of the group's collective welfare, how is this 'zero contribution' outcome best evaluated?
