Second Price Auction. In a second price auction with two bidders, we know from class that everyone bidding his valuation
(b1 = v2 and b2 = v2) is the dominant strategy equilibrium.
(a) Show that for player 1, bidding b0 1 < v1 is weakly dominated by bidding b1 = v1.
(b) In classes, we showed that any player 10s strategy b0 1 > v1 is weakly dominated by strategy b1 = v1. Combine the above two statements, what conclusion can you draw? Why this conclusion is relevant if we want to show (b1 = v2; b2 = v2) is the dominant strategy equilibrium?
