Evaluating Collective Action Problems
Imagine a community of 10 farmers who share a common water source for their crops. Each farmer can independently and secretly choose to either conserve water or use an excessive amount. Conserving water costs a farmer a little in potential yield but helps maintain the water level for everyone. Using an excessive amount gives that one farmer a significant boost in yield but lowers the water level, slightly harming the crops of all 10 farmers (including their own). Assuming every farmer is rational and motivated only by maximizing their own personal yield, first predict the most likely outcome of this situation. Then, evaluate this outcome from the perspective of the community's total yield. Is this outcome the best one for the group as a whole? Explain why or why not, and why this outcome is considered a stable equilibrium.

Four farmers must independently decide whether to contribute to a shared irrigation project. Contributing costs an individual farmer $10. For each farmer who contributes, every farmer in the group (including those who do not contribute) receives a benefit of $8. Each farmer's sole motivation is to maximize their own individual monetary payoff. What is the most likely outcome of this situation?
Strategic Decision in a Shared Resource Game
Explaining the Logic of a Suboptimal Equilibrium
Consider a scenario where a group of individuals can each contribute to a public project. Contributing has a personal cost, but generates a benefit that is shared equally among all members of the group, regardless of who contributes. If every individual acts solely to maximize their own personal outcome, the resulting equilibrium will be the one that provides the greatest total benefit to the group as a whole.
Evaluating Collective Action Problems
In the context of a game where self-interested individuals decide whether to contribute to a shared project, match each concept to its correct description.
Consider a scenario with a group of farmers who must each decide whether to contribute to a shared irrigation project. The personal cost to contribute is $10. For each farmer who contributes, every farmer in the group receives a benefit of $8. Given that each farmer acts solely to maximize their own individual payoff, the dominant strategy is not to contribute, resulting in a payoff of $0 for everyone. Which of the following changes to the rules would be sufficient to make 'contribute' the new dominant strategy for each farmer?
A group of four individuals are playing a game. Each can choose to 'cooperate' or 'defect'. Cooperating costs the individual $5, but adds $4 to the payoff of every player in the group (including themselves). Defecting has no cost and adds nothing to anyone's payoff. If all four players act solely to maximize their own individual payoff and follow their dominant strategy, the final payoff for each player will be ______.
A farmer is part of a group where each member must independently decide whether to contribute to a shared resource. Contributing has a personal cost, but each contribution provides a benefit to every member of the group (including those who do not contribute). The farmer's sole motivation is to maximize their own individual outcome. Arrange the following steps in the logical order a self-interested farmer would follow to determine their best strategy.
