Two individuals, Jamie and Chris, must decide how to divide a resource. Imagine a graph where Jamie's share is on the vertical axis and Chris's share is on the horizontal axis. A straight, downward-sloping 'Allocation Line' shows all possible divisions.

• Jamie's indifference curves are solid and relatively flat, meaning Jamie is willing to give up a small amount of their own share to see Chris's share increase by one unit.
• Chris's indifference curves are dashed and relatively steep, meaning

Analyzing Preferences in a Resource Allocation Scenario

Impact of Altruism on Allocation Choices

Altruism, Indifference Curves, and Strategic Choice

An individual's preferences about their own payoff versus another person's payoff can be represented by indifference curves. On a graph where the individual's own payoff is on the vertical axis and the other person's payoff is on the horizontal axis, match each type of preference to the shape of the indifference curve that represents it.

Consider two individuals, Player A and Player B, whose preferences for allocating a sum of money between themselves are represented by indifference curves. On a graph where a player's own payoff is on the vertical axis and the other player's payoff is on the horizontal axis, Player A's indifference curves are significantly steeper than Player B's. This implies that if both players were offered an identical choice between keeping the entire sum for themselves or splitting it evenly, Player A woul

Evaluating a Policy to Foster Cooperation

Analyzing a Shift in Allocation Strategy

An individual is deciding how to allocate a fixed sum of money between themself and another person. Their preferences are represented by a set of indifference curves on a graph, where their own payoff is on the vertical axis and the other person's payoff is on the horizontal axis. The possible allocations are shown by a straight, downward-sloping line. Initially, the individual chooses an allocation that gives a significant portion to the other person. If this individual's feeling of goodwill to
