(b) (4pts) Is the profile (b3 = v1 + 1 and bi = v6, for i 6= 3) a Nash equilibrium? Explain your answer. (c) (5pts) Find and verify all Nash equilibria in which player 3 wins the object. (Hint: Need to find and verify all Nash AND show that other strategy profiles are not Nash. Look at the example we did in class where Player 2 was the winner: How high must Player 2's bid be? How low must other players' bids be? Use those observations and Part (b) to answer this question.)
