Two bidders compete in a sealed-bid auction for a single indivisible object. For each bidder , the valuation of the object is uniformly distributed on [0, 1]. The valuations of the two bidders are independent. Each bidder knows her own valuation, but not the valuation of the other bidder. The bidders simultaneously submit bids b = [0, ∞), and whoever submits the higher bid wins the object and pays the average of the two bids. In case of a tie, each bidder wins the object with probability 1/2 and again the winner pays the average of the two bids. Find a Nash equilibrium of this game in which each bidder's strategy is linear in her valuation.

Two bidders compete in a sealed-bid auction for a single indivisible object. For each bidder
i, the valuation of the object is uniformly distributed on [0, 1]. The valuations of the two
bidders are independent. Each bidder knows her own valuation, but not the valuation of
the other bidder. The bidders simultaneously submit bids b = [0, ∞), and whoever submits
the higher bid wins the object and pays the average of the two bids. In case of a tie, each
bidder wins the object with probability 1/2 and again the winner pays the average of the two
bids. Find a Nash equilibrium of this game in which each bidder's strategy is linear in her
valuation.
