5. Find all the Bayesian-Nash equilibria in pure strategies. Consider the following normal form game 1 A B 2 A B -1,-1 1,0 0,1 0,0 Now introduce a bit of incomplete information in the following way. In the incomplete information version player i gets (1+t) when it plays A and its rival plays B. Here t, is private information for player i. Each player j believes that t; (ij) is uniformly distributed over [- +e]. Everything else is the same as in the original game. Show that when e converges to zero the pure strategy Bayesian- Nash equilibrium converges to the mixed strategy Nash equilibrium of the complete information game.

A B
-1,-1 1,0
A
B 0,1 0,0
Now introduce a bit of incomplete information in the following way. In the incomplete information
version player i gets (1+t) when it plays A and its rival plays B. Here t, is private information for
player i. Each player j believes that t (ij) is uniformly distributed over [-e, +E]. Everything else
is the same as in the original game. Show that when e converges to zero the pure strategy Bayesian-
Nash equilibrium converges to the mixed strategy Nash equilibrium of the complete information game.
