Total Cost is the sum of Worry Value and which component?

• A. Premium
• B. Expected Cost
• C. P*
• D. Monetary Cost

Answer: (B)

In this approach to evaluating decisions under uncertainty, total cost combines two elements: the Worry Value, which captures the psychological discomfort or disutility from risk, and the Expected Cost, which is the probability-weighted average of monetary losses. The total cost is defined as the sum of these two, because you want to account for both how much you might lose on average and how much the risk itself weighs on you emotionally. The premium, monetary cost, or any placeholder like P* don’t fit this particular decomposition. The premium is just a fixed payment for insurance and doesn’t represent the expected loss under uncertainty, while monetary cost describes an actual outlay in a specific scenario rather than its expectation. P* isn’t part of this cost framework either. For example, if the expected monetary loss is $2,000 and the worry value is $1,500, the total cost would be $3,500, illustrating why the correct component to add to the Worry Value is the Expected Cost.
