Using Game Theory to Model Social Interactions
Game theory provides the analytical tools to model social interactions, which are situations where individual decisions impact the outcomes of others. This framework is used to investigate the emergence of social dilemmas and to explore potential solutions, as well as to understand why some dilemmas, like climate change, persist.

Modeling Climate Negotiations as a Game Between the US and China
An economist develops a model where only two neighboring farms must independently decide whether to reduce their water usage from a shared, depleting aquifer. The stated purpose of this model is to understand the challenges of achieving widespread conservation among thousands of users in a large water basin. What is the primary justification for using such a highly simplified, two-actor model to study this complex, large-scale problem?

Justifying Model Simplification in Economics
An economist seeks to understand a complex social problem by first creating a simplified model. The key assumption in this model is that individuals make their decisions independently and without any direct coordination. Which of the following large-scale problems is most suitable for analysis with a model based on this specific assumption?
The key assumption in a simple two-farmer economic model—that each farmer acts independently without coordinating with the other—is included because it is the most accurate and realistic depiction of how all individuals interact in large-scale social problems.
To understand a complex global issue, an economist models it as a simple game between two farmers deciding independently whether to use a polluting technology. Match each element of this simplified model to the principle or real-world feature it represents.
A simple economic model demonstrates that two neighboring farms, each acting independently to maximize their own profit, will both choose to use a pesticide that contaminates a shared water source. This leads to a worse outcome for both farms than if they had coordinated to avoid using the pesticide. When this model's insight is applied to a large-scale environmental problem involving thousands of independent actors, what fundamental issue does it highlight?

Methods for Mitigating Social Dilemmas
Analyzing a Strategic Business Decision
Two farmers, Anil and Bala, must independently decide whether to use an inexpensive but polluting fertilizer ('Terminator') or a more expensive, environmentally-friendly fertilizer ('Integrated Pest Control' or IPC). The table below shows their potential profits (in thousands of dollars) for each combination of choices. The first number in each cell is Anil's profit, and the second is Bala's.
Bala chooses IPC Bala chooses Terminator Anil chooses IPC 3, 3 1, 4 Anil chooses Terminator 4, 1 2, 2 Assuming both farmers act solely to maximize their own individual profit, what is the most likely outcome of this interaction?
Explaining Social Dilemmas with Game Theory
Match each game theory component to its correct description in the context of a social interaction.
In a social interaction modeled as a one-time game, if every participant independently chooses the action that maximizes their own personal payoff, the resulting outcome is guaranteed to be the best possible outcome for the group as a whole.
Analyzing a Competitive Pricing Dilemma
You are an analyst tasked with modeling a strategic interaction between two competing firms. Arrange the following steps in the logical order you would take to determine the likely outcome of their interaction.
Altering Incentives in a Business Rivalry
Two competing companies are deciding whether to adopt a new, costly, environmentally-friendly production process. If both adopt it, they both see a moderate increase in profit due to an improved public image. If one adopts it and the other does not, the one that adopted it sees a sharp decrease in profit due to high costs, while the other sees a large increase in profit. If neither adopts it, their profits remain unchanged. Assuming each company makes its decision independently and aims only to maximize its own profit, which statement best analyzes this strategic interaction?
