Interesting game theory for Johns Hopkins students. This game theory is that “In several computer science courses at Johns Hopkins University, the grading curve was set by giving the highest score on the final an A, and then adjusting all lower scores accordingly. The students determined that if they collectively boycotted, then the highest score would be a zero, and so everyone would get an A. Amazingly, the students pulled it off:”
There are two Nash equilibria. #1 Equilibria is no one takes the test, and #2 equilibria is every one take exam. Both equilibria is depend on every student. If one student refuse to boycott the exam, every student has to take the final exam. However, which one should we prefer if we can get an A grade without studying and participate the exam. It is too obvious to predict. Even though the problem of of Nash equilibria, it was a great deal to pull a student.
