Anil's Altruistic Best Response if Bala Chooses IPC
This example demonstrates how to find Anil's best response when he has altruistic preferences and Bala chooses Integrated Pest Control (IPC). When Bala plays IPC, Anil must compare his two possible outcomes. If he also chooses IPC, the allocation is (I,I), corresponding to the point (3,3) on the graph with its associated payoffs. If he chooses Toxic Tide (T), the allocation is (T,I), corresponding to the point (4,1). By observing the graph of Anil's altruistic preferences, it is clear that the point (3,3) lies on a higher indifference curve than the point (4,1). Since Anil's utility increases on curves further from the origin, he prefers the (I,I) outcome. Therefore, his best response is to choose IPC.

Analyzing Decisions with Altruistic Preferences
An individual, Person A, has altruistic preferences, meaning their satisfaction depends on both their own and another person's (Person B's) outcome. Suppose Person B has already chosen an action, and Person A must now choose their own action. Person A's choice will lead to one of two possible outcomes:
- If Person A chooses 'Cooperate', the outcome is (3, 3), where the first number is Person A's payoff and the second is Person B's.
- If Person A chooses 'Defect', the outcome is (4, 1).
Person A's satisfaction is represented by a set of indifference curves, where curves further from the origin (0,0) represent higher levels of satisfaction. The outcome (3, 3) is located on a higher indifference curve than the outcome (4, 1).
Given this information, what is Person A's best response, and why?
Consider an individual whose satisfaction depends on both their own and another person's outcomes. If this individual is faced with two choices, they will always select the choice that results in the highest personal monetary payoff for themselves.
Decision-Making with Altruistic Preferences
Altruistic Investment Decision
An individual, Player 1, has altruistic preferences, meaning their satisfaction is represented by indifference curves that value both their own and another person's (Player 2's) payoff. Player 2 has already acted. Player 1 must now choose between two options, leading to the following outcomes (Player 1's payoff, Player 2's payoff):
- Option A: Results in outcome (5, 5)
- Option B: Results in outcome (6, 2)
Player 1's indifference map shows that the outcome (5, 5) lies on a higher indifference curve (representing greater satisfaction) than the outcome (6, 2). Match each concept below to its correct description based on this scenario.
An individual with altruistic preferences must choose between two outcomes: Outcome A results in a payoff of (3, 3) and Outcome B results in a payoff of (4, 1). The first number in each pair is the individual's own payoff, and the second is another person's payoff. The individual's preferences are such that Outcome A provides a higher level of overall satisfaction (utility) than Outcome B. Which statement best analyzes the individual's optimal choice?
Evaluating a Strategic Choice with Altruistic Preferences
A person's satisfaction depends on both their own and another's well-being, represented by a map of indifference curves where curves further from the origin indicate higher satisfaction. This person must choose an action that will result in one of two possible outcomes. Arrange the following steps in the logical order this person would follow to determine their best response.
An individual with altruistic preferences is choosing between two actions. Action A results in a personal payoff of $10 and a payoff of $2 for another person. Action B results in a personal payoff of $8 and a payoff of $8 for the other person. If the individual chooses Action B, they are doing so because it maximizes their overall ____, which is represented by reaching a higher indifference curve.
