Definition§
Expected Utility is a key concept in economics that represents an individual’s anticipated satisfaction, or utility, derived from various possible outcomes of a decision, while taking into account the probabilities of each outcome. It serves as a decision-making framework where individuals weigh their preferences against uncertainty.
| Expected Utility | Utility Maximization |
|---|---|
| Measures satisfaction based on the probabilities of outcomes | Focuses on choosing the most beneficial option regardless of uncertainty |
| Incorporates risk and uncertainty in decision making | May overemphasize certain outcomes while ignoring others |
| Helpful in scenarios with multiple uncertain outcomes | Generally applies in more straightforward, deterministic situations |
Examples of Expected Utility§
-
Insurance: When buying insurance, individuals assess the low probability (but serious consequences) of a risk occurring (like a car accident) and weigh that against the premium cost. Expected utility helps in evaluating if the peace of mind (utility) gained from insurance is worth the price paid.
-
Gambling: Gamblers may calculate their expected utility from betting on certain games based on the probability of winning vs. the payout.
