While grading a final exam a professor discovers that two students have virtually identical answers. She talks to each student separately and tells them that she is sure that they shared answers, but she cannot be sure who copied from whom. She offers each student a deal-if they both sign a statement admitting to the cheating, each will be given an F for the course. If only one signs the statement, that student will be allowed to withdraw from the course and the other nonsigning student will be expelled from the university. Finally, if neither signs the statement they will both get a C for the course because the professor does not have enough evidence to prove that cheating has occurred. Assuming the students are not allowed to communicate with one another, set up the relevant payoff matrix.

O If withdrawing is worse than a C, then both have a dominant strategy to sign. O Yes, because the worst outcome is being expelled so they will both the F.

separately and tells them that she is sure that they shared answers, but she cannot be sure who copied from whom. She offers each
student a deal-if they both sign a statement admitting to the cheating, each will be given an F for the course. If only one signs the

university. Finally, if neither signs the statement they will both get a C for the course because the professor does not have enough
evidence to prove that cheating has occurred. Assuming the students are not allowed to communicate with one another, set up the
relevant payoff matrix.
