Explaining Suboptimal Outcomes in Strategic Interactions
Imagine a scenario involving two neighboring farms. Each farmer must independently decide whether to use a cheap, highly effective pesticide that pollutes a shared water source, or a more expensive, less-polluting alternative. If both use the cheap pesticide, the water becomes severely contaminated, and both farms suffer significant losses. However, for each individual farmer, using the cheap pesticide is always the most profitable choice, regardless of what the other farmer does. Explain the reasoning behind why both farmers choosing their most profitable individual option results in an outcome that is worse for both of them.

Analyzing Strategic Outcomes
In some strategic interactions, the independent pursuit of self-interest by all parties leads to an outcome that is best for everyone involved (an 'invisible hand' outcome). In contrast, consider a scenario with two farmers where if both independently choose the most individually profitable pest control method, the resulting pollution makes them both worse off than if they had coordinated on a different method. What is the fundamental reason for this difference in outcomes?
Consider two different strategic interactions. Match each scenario with the description of the outcome that is most likely to occur when all individuals act solely in their own self-interest.
A common economic principle suggests that when individuals independently pursue their own self-interest, the outcome is often the best one for the group as a whole. Which of the following situations provides the strongest counterargument to this principle, demonstrating how the pursuit of self-interest can lead to a mutually undesirable outcome?

Contrasting Outcomes of Self-Interested Behavior
The primary difference between a strategic interaction where self-interest leads to a mutually beneficial outcome (an 'invisible hand' scenario) and one where it leads to a mutually detrimental outcome (like the pest control game) is that players in the latter scenario are not acting in their own self-interest.
Altering Incentives in a Strategic Interaction
Evaluating a Policy Intervention in a Strategic Interaction
Consider the following strategic interaction between two competing coffee shops, 'Bean Town' and 'The Grind', who are deciding whether to offer a deep discount on lattes. The table below shows the daily profits for each shop based on their decisions. The first number in each pair is Bean Town's profit, and the second is The Grind's profit.
The Grind: Discount The Grind: No Discount Bean Town: Discount $50, $50 $150, $20 Bean Town: No Discount $20, $150 $100, $100 Based on an analysis of this situation, where each shop acts in its own self-interest, which statement best describes the outcome?
