Classification of Social Preferences
Social preferences can be categorized based on how an individual's utility is affected by the well-being of others. Key types include altruism, where another's benefit increases one's own utility; inequality aversion, which is a preference for more equitable outcomes; and spite or envy, where another's benefit decreases one's own utility.

Situational Nature of Social Preferences
In a one-time, anonymous interaction, Person A is given $20 and can offer any portion of it to Person B. Person B has no choice but to accept the offer. A model assuming individuals are motivated solely by their own financial gain would predict that Person A will offer $0 and keep the full $20. However, in real-world experiments, Person A often chooses to offer a positive amount (e.g., $5). Which of the following provides the best explanation for this observed behavior?
An economic model that incorporates the idea that individuals' utility can be influenced by the well-being of others will always predict more generous and cooperative outcomes compared to a model assuming individuals only care about their own direct payoffs.

Spite and Envy as Social Preferences
An individual is offered two ways to split a bonus between themselves and a colleague. In Option 1, the individual gets $100 and the colleague gets $20. In Option 2, both the individual and the colleague get $80. The individual chooses Option 2. This decision to accept a lower personal payoff in favor of a perfectly even distribution is the clearest demonstration of which type of social preference?

Distinguishing Motivations for Fairness
An individual is given the choice between two outcomes. Outcome A: they receive $10 and another person receives $18. Outcome B: they receive $9 and the other person receives $9. If the individual chooses Outcome B, this action exclusively demonstrates that their utility is negatively affected by the well-being of others.
Comparing Social Preference Models
Interpreting Choices to Identify Social Preferences
An individual's satisfaction from an outcome is represented by the utility function U(x_i, x_j) = x_i - 0.5 * x_j, where x_i is the individual's own monetary payoff and x_j is another person's monetary payoff. Based on this function, what type of social preference does this individual exhibit?
