Consider a second-price sealed-bid auction. Suppose bidders' valuations are v1=10 and v2=10. Select all that apply. (PLEASE EXPLAIN CHOICES COMPLETEY) a. One bidder submitting a bid equal to 10 and the other submitting a bid equal to 0 is a Nash equilibrium. b. Bidding a value b1 equal to her own valuation v1 is a weakly dominated strategy for bidder 1. c. Both bidders submitting bids equal to 0 is a Nash equilibrium. d. Both bidders submitting bids equal to...

A second-price sealed-bid auction is an auction in which every bidder submits his or her bid to the auctioneer, the auctioneer announces the winner to be the bidder who submits the highest bid, and the winner pays the highest bid among the losers. Is the following statement True, False, or Uncertain? Explain why. Every player has a weakly dominant strategy in second-price auction.

Second Price sealed bid-auction: Assume n players are bidding in an auction in order to obtain an indivisible object. Denote by vi the value player i attaches to the object; if she obtains the object at the price p her payoff is vi −p. Assume that the players’ valuations of the object are all different and all positive; number the players 1 through n in such a way that v1 > v2 > · · · > vn > 0....

Question 6. There are two bidders in a sealed-bid, second-price auction. The object for sale has a common value. Each bidder, i = 1,2, receives a signal i that is independently and uniformly distributed on the interval [0, 1]. The true value of the object, v, is the average of the two signals, v = (σ1 + σ2) / 2 (a) If bidder 1 gets the signal σ = 0.7, how much does he think the object is worth? (b)...

Consider 45 risk-neutral bidders who are participating in a second-price, sealed-bid auction. It is commonly known that bidders have independent private values. Based on this information, we know the optimal bidding strategy for each bidder is to: A. bid their own valuation of the item. B. shade their bid to just below their own valuation. C. bid according to the following bid function: b = v − (v − L)/n. D. bid one penny above their own valuation to ensure...
