Consider a second-price sealed-bid auction as the one analyzed in class. Suppose bidders' valuations are v1-10 and v2=10. Select all that apply. a. Bidding a value b1 equal to her own valuation vy is a weakly dominated strategy for bidder D. Both bidders submitting bids equal to 10 is a Nash equilibrium. C. One bidder submitting a bid equal to 10 and the other submitting a bid equal to 0 is a Nash equilibrium. d. Both bidders submitting bids equal...

3.6. Consider a first-price, sealed-bid auction in which the bid- ders' valuations are independently and uniformly distributed on (0,1). Show that if there are n bidders, then the strategy of bid- ding (n-1)/n times one's valuation is a symmetric Bayesian Nash equilibrium of this 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....

Suppose you are a bidder in a first-price sealed-bid auction for a single object, where players submit bids simultaneously and the player who bid the highest wins the object and must pay his/her bid. Assume there are two other bidders, so this is a three-player game. You do not observe the valuations of the other bidders, but assume that you believe their valuations are identically and independently distributed according to a uniform distribution on the interval from 0 to 20....

Four bidders participate in first price auction for a single object that is of the following value to them: V1 = 150, V2 = 100, V3 = 90, V4 = 80 The information above is known to all (i.e., each bidder knows not only his own valuation but also that of the other bidders). If two bidders or more bidders place the same bid, one of them is selected at random to be the winner. Select all that apply a. There's a Nash...

Three (3) bidders participate in a first price, sealed bid auction satisfying all the assumptions of the independent private values model. Each knows his own value v ∈ [0, 1], but does not know anyone else's, and so must form beliefs. Suppose everyone thinks it is more likely a rival's value is high than low. Specifically, each player believes any other player's value is distributed on [0, 1] according to the cumulative distribution function F(v) = v3, and this is...

Consider a first price auction for selling one item. There are n bidders. Each bidder i has a valuation vi for the item, which is privately known and drawn independently from a uniform distribution of interval [0,50]. Each bidder i bids a non-negative real number bi. The bidder who bids the highest number wins and if more than one bidder bid the highest, the winner is chosen uniformly at random. The winner gets the item and pays her bid. All...

Suppose three risk-neutral bidders, named 1, 2 and 3, are interested in purchasing a painting. The bidders' values are 12, 14 and 16. The bidders will compete in an auction. Suppose all bids must be made in increments of $1 and be between $5 and |$25 Who wins in a sealed-bid second price auction? What are the final price and the payoff to the winning bidder?
