Use the following data to work Larry lives in a neighborhood in which 20 percent of the cars are stolen every year. Larry's car, which he parks on the street overnight, is worth $\$ 20,000$ (This is Larry's only wealth.) The table shows Larry's utility of wealth schedule. If Larry cannot buy auto theft insurance, what is his expected wealth and his expected utility?

Key Concepts

Expected Value

The expected value is a fundamental concept in probability and decision theory that represents the average outcome of a random event over many trials. In the context of wealth, it is computed by multiplying each possible outcome by its probability and summing the results. This approach is used to evaluate the monetary value that a person can anticipate, considering all potential scenarios, such as the case of auto theft affecting Larry's wealth.

Utility Function

A utility function is a mathematical tool used in economics to assign a level of satisfaction or utility to different amounts of wealth or outcomes. It captures an individual's preferences and risk attitude, meaning that a person’s utility from money may not increase linearly with the amount of wealth. In decision-making under uncertainty, the utility function helps compare various outcomes beyond their monetary value by taking into account the decreasing marginal utility of wealth.

Expected Utility

Expected utility combines the concepts of expected value and the utility function to represent the average level of satisfaction, or utility, that an individual can expect from uncertain outcomes. Instead of considering just the monetary outcomes, expected utility weights each utility value by the probability of its corresponding outcome. This method provides a more comprehensive assessment of decision making under risk, reflecting both the probabilities of different wealth levels and the individual's risk preferences.
