Four farmers are deciding independently whether to contribute to a shared irrigation project. If a farmer contributes, they incur a personal cost of $10. For each farmer who contributes (including themselves), all four farmers receive a benefit of $8. For example, if only one farmer contributes, that farmer's net payoff is -$2 ($8 benefit - $10 cost), while the other three non-contributing farmers each get a payoff of $8. If all four contribute, each farmer's net payoff is $22 ($32 total benefit - $10 cost). From the perspective of a single farmer, which statement best analyzes their decision?

Predicting Outcomes in a Social Dilemma

Consider a scenario where four farmers independently decide whether to contribute to a shared irrigation project. The outcome where all four farmers contribute results in the highest possible collective payoff for the group. This outcome is a stable equilibrium because it maximizes the overall benefit for all participants.

Explaining the Social Dilemma in a Shared Resource Scenario

In a game where four farmers independently decide whether to contribute to a shared irrigation project, different outcomes are possible. Match each outcome scenario with the statement that best describes its strategic implications.

A single farmer is participating in a shared irrigation project with three other farmers. The farmer is considering their own potential net payoff based on the number of other farmers who choose to contribute. Each contribution costs the contributor $10, and each contribution (including their own) provides an $8 benefit to all four farmers. Arrange the following scenarios from the highest potential net payoff to the lowest potential net payoff for this single farmer.

In a scenario where four farmers independently decide whether to contribute to a shared irrigation project, each farmer calculates that their personal payoff is always higher if they choose not to contribute, no matter what the other three farmers decide to do. Therefore, for each individual farmer, the action of not contributing is known as a ________ strategy.
