The economic value created is lower because of the difference in consumer surplus.

Quick Scoop: What’s Going On Here?

The question is about a standard microeconomics concept: how much total benefit society gets from a trade. In simple terms, if Sarah is willing to pay more for the pie than Jean is, selling to Jean instead of Sarah means society “leaves value on the table” because the pie doesn’t go to the person who values it most.

In this multiple‑choice style question, the specific term that captures “difference in how much the buyer values the good” (willingness to pay) is consumer surplus, not production costs, producer surplus, reservation price, or purchase price.

Mini Breakdown

• Consumer surplus = buyer’s willingness to pay minus the actual price paid.

• If Sarah’s willingness to pay is higher than Jean’s, Sarah would enjoy more consumer surplus from the same pie.
• When Frank sells to Jean instead of Sarah, total surplus (overall economic value) falls because the pie goes to someone who values it less, reducing total consumer surplus in society.

In textbook terms, “the economic value created in society is lower because of the difference in consumer surplus between Jean and Sarah.”

TL;DR: The correct answer is consumer surplus.
