Dan owns an autographed copy of a Brittany Spears CD that he values at $100. If he
sells the CD at the garage sale he’s planning to hold in a few weeks, it will be sold to a
buyer with a reservation price of $175. If he sells it on eBay, it will be sold to a buyer
with a reservation price of $500. eBay will charge Dan $50 to auction the CD, which
just covers eBay’s opportunity cost of running the auction. Relative to selling the CD at
his garage sale, auctioning the CD on eBay will lead:
A. to no change in total economic surplus.
B. total economic surplus to increase by $500.
C. total economic surplus to increase by $275.
D. total economic surplus to increase by $100.
Refer to the figure below. The law of diminishing marginal utility:
