Premise: Suppose Eric bought a ticket to theLakersgame for $100, and that he is excited to go (because theLakersare awesome, and the seats are great). Eric values seeing theLakers, with seats in that section, at $150. Now suppose that Eric lost the tickets. He was driving back from Las Vegas, holding them out the window to brag to the drivers in the other cars, when they blew out of his hands. He looked and looked, but they're gone (drat!).

Eric has come to you, since he knows you're interested in economics, and asks what he should do? Should he buy another ticket? (suppose that Eric's financial situation has not changed since he originally bought theLakerstickets, and that tickets with the exact same value to Eric are available at the exact same price that he paid originally.)

Support your advice to Eric and prove that you can "Think Like an Economist."
