Question
![A buyer and a seller each have private information about their own valuations of a
single object that the seller may sell to the buyer. The buyer's valuation, denoted
V, and the seller's valuation, denoted v,, are independently drawn from a uniform
distribution on the interval [0, 1]. The buyer names an offer price, Pb (a nonnegative
number), and the seller simultaneously names an asking price, p, (a nonnegative
number). If p, < Ps, there is no trade; the payoffs to both the buyer and the seller are
0. If p. > Ps, trade occurs at the price p = tp); the payoff to the buyer is v, – p
and the payoff to the seller is p- vs.

![(a) Specify the strategic situation as a Bayesian game.
(b) Find all the values of a such that the game has a Nash equilibrium in which the
buyer offers æ if v, > r and 0 otherwise, and the seller asks r if v, < x and 1
otherwise.
(c) (optional) Show that the game has a Nash equilibrium in which the buyer uses
the linear offer price function p(vb)
price function p,(v.) = v, +.
vr +5 and the seller uses the linear ask
