It’s Haley’s 21st birthday. She and Claire have decided to get coordinating tattoos. Claire got hers first and now Haley is having a change of heart. In this scene, we see time inconsistency and imperfect information. Haley is concerned that her preferences will change over time so she decides against getting the tattoo. Meanwhile, Claire already regrets her tattoo because Haley won’t be getting one – but it’s too late for Claire. Tattoos do not have a return policy! If Claire had known that Haley would change her mind, she would not have gotten a tattoo (imperfect information). This clip can also be used to compare and contrast two types of games in game theory – sequential games and simultaneous games. If you decide to get a tattoo with a friend but only because you’re doing it with a friend, make sure you get them simultaneously!

Haley, Phil and Luke are participating in a psychology study. Luke has convinced Phil that they should push the big red button that says “DO NOT PUSH” but Haley stops them. She says one in a million college drop outs go on to become Steve Jobs. The other 99 thousand don’t (her math is a little off). She recently dropped out of college and is having a crisis. This demonstrates several economic concepts including the importance of human capital and time inconsistency. Human capital comes from going to college but Phil reminds her that there are other sources of human capital. Time inconsistency occurs when you regret a decision in the past.

Luke was supposed to keep a journal all summer, but when school starts again, he realizes he only did one day. Luke’s focus on the present (at the beginning of the summer) imposes large negative externalities on his back when it’s time to turn in the work later in the summer.
