The Irrigation Game as an Example of a Public Good Game
The irrigation game, involving four farmers deciding on funding a shared system, serves as a classic example of a public good game. This classification is based on the game's core structure: an individual farmer bears a personal cost to contribute, but the resulting benefit is shared among all farmers. This dynamic creates a social dilemma, as each player has an incentive to free-ride on the contributions of others rather than pay the cost themselves.

The final crop yield, and thus the farmer's profit, depends on the amount of fertilizer used and the amount of rainfall during the growing season. The farmer is aware of this relationship but has no control over the weather. Why does this situation FAIL to qualify as a strategic interaction?

A city builds a new lighthouse on its coast. The light from the lighthouse helps all ships in the area navigate safely, regardless of how many ships are present. The city funded the construction through taxes, and it is impossible to charge individual ships for using the light as they pass. Which aspect of this situation best demonstrates the defining characteristic of a public good?
A key characteristic used to classify economic goods is 'rivalry'—the extent to which one person's use of a good diminishes its availability for others. A good is considered 'non-rival' if one person's consumption does not reduce the amount available for someone else. Which of the following scenarios describes a good that is best characterized as non-rival?
Community Project Funding Dilemma
A good can be classified based on two key characteristics: whether its consumption by one person prevents another from consuming it (rivalry), and whether it is possible to prevent people who have not paid for it from having access to it (excludability). Match each type of good with its correct description based on these characteristics.

Evaluating a Policy for Improving Air Quality
A company develops a new, highly effective mosquito repellent formula and sprays it over a large public park. The spray eliminates all mosquitoes in the area for a week, and anyone visiting the park benefits from the mosquito-free environment. The company cannot charge individual park visitors for this benefit. However, the pleasant, mosquito-free air in the park does not extend to the surrounding neighborhoods. Which statement best analyzes this situation in the context of a public good?
A national radio station incurs a total cost of $50,000 to produce and transmit a specific one-hour program.

In a two-person economy, Person A is forced to work 12 hours a day to produce 20 bushels of wheat. Person B, who enforces this arrangement, takes 19 bushels and leaves Person A with 1 bushel, which is just enough to survive. Given the production possibilities, it is impossible to produce more than 20 bushels with 12 hours of work. Which statement accurately analyzes this allocation?
Four students are assigned to create a shared online study guide for an exam. The final guide will be accessible to all four, regardless of who contributes. Each student must decide independently whether to spend several hours creating high-quality content (a personal cost) or to do nothing and hope others complete the work. If each student acts solely to maximize their own personal benefit (getting a good study guide with the least personal effort), what is the most probable outcome of this situation?
Neighborhood Watch Dilemma
Three roommates share a kitchen. Each roommate independently decides whether to spend an hour cleaning it. The personal cost of cleaning is valued at $6. If at least one person cleans, each of the three roommates receives a benefit equivalent to $5 from having a clean kitchen. If you are one of the roommates and you decide to clean while the other two do not, what is your individual net payoff?
In a one-time strategic interaction where each participant can choose to pay a personal cost to create a larger collective benefit for the entire group, the most predictable outcome is that the collective benefit will be maximized because each rational individual understands that cooperation is best for the group as a whole.

The Irrigation Game as an Example of a Public Good Game
The Irrigation Project Decision
Four farmers share an irrigation system. Each can choose to contribute $10 to a maintenance project. For every $10 contributed, the total value of crops for each of the four farmers increases by $8. A farmer's net gain is their increase in crop value minus any contribution they made. From the perspective of a single farmer, which of the following statements accurately analyzes their best financial decision?
Individual vs. Group Incentives in a Shared Project
Evaluating Outcomes in a Shared Resource Scenario
Four farmers share an irrigation system. Each farmer can choose to contribute $10 to a maintenance project. For every $10 contributed, the total value of crops for each of the four farmers increases by $8. A farmer's net payoff is their increase in crop value minus their own $10 contribution (if they made one). Match each scenario with the correct net payoff for the farmer described as 'you'.
Consider a scenario with four farmers who share an irrigation system. Each farmer can independently choose to contribute $10 to a maintenance project. For every $10 contributed, the crop value for each of the four farmers increases by $8. True or False: The outcome that generates the greatest total financial benefit for the group of farmers is the most likely outcome to occur.
Consider a scenario with four farmers who can each contribute $10 to a shared irrigation project. For each contribution made, every farmer's crop value increases by $8. Comparing a farmer who contributes with a farmer who does not, the contributing farmer's final net payoff will always be $____ less than the non-contributing farmer's payoff, regardless of how many others contribute.
A single farmer is deciding whether to contribute $10 to a shared irrigation project. Four farmers in total use the system. For each $10 contribution, every farmer's crop value increases by $8. Arrange the following steps to reflect the logical reasoning process this farmer would use to arrive at their individually optimal decision, assuming they want to maximize their own net financial gain.
Impact of a Subsidy on a Shared Project
In a shared irrigation project with four farmers, each farmer must decide whether to contribute $10. In the original scenario, each contribution increases every farmer's crop value by $8, creating a social dilemma where individual self-interest conflicts with the group's best interest. Now, imagine a new technology is introduced that makes the irrigation system more efficient. With this new technology, each $10 contribution now increases every farmer's crop value by $12. How does this change affect an individual farmer's decision-making?
