Individual Incentive to Free-Ride in the Worldwide Public Good Game

Introduction of a Punishment Option in the Public Good Game Experiment

In a single round of an economic experiment, a group has four members. Each member is given $20 and can contribute any amount to a common fund. For every dollar in the fund, each of the four members receives a payout of $0.40. Imagine you are one of the members, and the other three members have contributed a total of $30 to the fund. Analyze your own financial outcome based on two choices: contributing $10 versus contributing $0. Which statement correctly identifies your best strategy for maximizing your personal payoff in this round?

The Role of Information in a Cooperative Game

Analyzing Payoffs in a Cooperative Game

In an economic experiment, four-person groups play a game for ten rounds. In each round, every participant receives $20 and can contribute any amount to a shared fund. For every dollar contributed to the fund, each of the four members (including the contributor) receives a benefit of $0.40. Suppose in one round, the total contribution from all four members to the shared fund is $40. What is the total net financial gain for the group as a whole in this round?

Critiquing an Experimental Design for Studying Cooperation

In an economic experiment, four-person groups play a game. In each round, every participant receives $20 and can contribute any amount to a shared fund. For every dollar contributed to the fund by any player, each of the four members receives a benefit of $0.40. If a single player decides to contribute $1 of their own money to the shared fund, what is the net change in that specific player's personal wealth resulting directly from that $1 contribution?

Calculating Individual Payoff in a Public Good Game

An economic experiment is conducted with four-person groups. In each round, every participant is given $20 and can contribute any amount to a shared fund. For every dollar contributed to the fund, each of the four members (including the contributor) receives a benefit of $0.40. Based on these rules, the course of action that maximizes a single player's personal financial gain in a round is the same course of action that maximizes the total financial gain for the group as a whole.
