- Consider a Common Value auction with two bidders who both receive a signal X that is uniformly distributed between 0 and 1. The (common) value V of the good the players are bidding for is the average of the two signals, i.e. V = (X1+X2)/2. the symmetric Nash equilibrium bidding strategy for the second-price sealed-bid auction assuming that players are risk-neutral and have standard selfish preferences. Furthermore, you may assume that the other bidder is following a linear bidding strategy. Make sure to explain your notation and the steps you take to derive the result.Discrete All-Pay Auction: In Section 6.1.4 we introduced a version of an all- pay auction that worked as follows: Each bidder submits a bid. The highest bidder gets the good, but all bidders pay their bids. Consider an auction in which player 1 values the item at 3 while player 2 values the item at 5. Each player can bid either 0, 1, or 2. If player i bids more than player j then i wins the good and both pay. If both players bid the same amount then a coin is tossed to determine who gets the good, but again both pay. a. Write down the game in matrix form. Which strategies survive IESDS? b. Find the Nash equilibria for this game.Consider a Common Value auction with two bidders who both receive a signal X that is uniformly distributed between 0 and 1.

- Complete Information: Consider a set of N players participating in a sealed- bid second-price auction, but assume that there is complete information so that each player knows the valuation of every other player. a. Is it still true that each player bidding his valuation is a weakly domi- nant strategy? b. Are there other Nash equilibria of this game?Consider a Vickery auction. There are N bidders, each of them values the object £vi, with i = 1…N. Each bidder can submit a bid in a sealed envelope. Once all the bids have been made, the envelopes are opened. The winner of the auction is the bidder who made the highest bid, however, s/he pays the second-highest bid. What are the weakly dominant strategies in this game? Is there only one?Consider this "all-pay" auction in which the highest bidder wins and both bidders must pay an amount equal to their bid regardless of whether they win or lose. It is common knowledge that Bidder 1 has a valuation of 2 and Bidder 2 has a valuation of 3. The bids must be whole numbers and Bidder 2 wins in the event of tie. Which of the following are Nash equilibria? Bidder 2 1 2 3 4 0, 3 0, 2 0, 1 0,0 0, -1 1 1,0 -1, 2 -1, 1 -1, 0 -1, -1 Bidder 1 2 0,0 О, -1 -2, 1 -2, 0 -2, -1 3 -1, 0 -1, -1 -1, -2 -3, 0 -3, -1 4 -2, 0 -2, -1 -2, -2 -2, -3 -4, -1 Note: The notation [0], [1], etc. denotes the pure strategies in which the bidder bids 0,1, etc. Mixed strategies are represented by weighted averages of the pure strategies, e.g the mixed strategy in which a bidder bids 1 with a probability of 1/4 and 4 with a probability of 3/4 is written as 1/4 [1] + 3/4 [4]. O ([0], [3]) O ([0], [1]) O ((1], [O]) (5/12 [0] + 1/3 [1] + 1/4 [2], 1/2 [0] + 1/2 [1]) O (2/3 [0] + 1/3 [1], 1/2 [0] + 1/2 [1]) O…
- Person A English Chinese English 10,10 5,0 Person B Chinese 0,5 5,5 A) Find the Nash equilibria of this two-person game in mixed strategies. B) Is there an equilibrium in which everybody prefers speaking English? If yes, is it stable? C) Is there an equilibrium in where everybody prefers speaking Chinese? If yes, is it stable? D) Is there an equilibrium where some people prefer speaking English, and some prefer speaking Chinese? What is the equilibrium value of p, and is this equilibrium stable?Suppose two bidders compete for a single indivisible item (e.g., a used car, a piece of art, etc.). We assume that bidder 1 values the item at $v1, and bidder 2 values the item at $v2. We assume that v1 > v2. In this problem we study a second price auction, which proceeds as follows. Each player i = 1, 2 simultaneously chooses a bid bi ≥ 0. The higher of the two bidders wins, and pays the second highest bid (in this case, the other player’s bid). In case of a tie, suppose the item goes to bidder 1. If a bidder does not win, their payoff is zero; if the bidder wins, their payoff is their value minus the second highest bid. a) Now suppose that player 1 bids b1 = v2 and player 2 bids b2 = v1, i.e., they both bid the value of the other player. (Note that in this case, player 2 is bidding above their value!) Show that this is a pure NE of the second price auction. (Note that in this pure NE the player with the lower value wins, while in the weak dominant strategy equilibrium where both…Hello, please help me to solve this question in Game Theory. Thanks in advance!Consider a first price sealed-bid auction of an object with two bidders. Each bidder i’s valuation of the object is vi, which is known to both bidders. The auction rules are that each player submits a bid in a sealed envelope. The envelopes are then opened, and the bidder who has submitted the highest bid gets the object and pays the auctioneer the amount of his bid. If the bidders submit the same bid, each gets the object with probability 0.5. Bids must be integers. Find a Nash equilibrium for this game and show whether it is unique.
- Game Theory Consider the entry game with incomplete information studied in class. An incumbent politician's cost of campaigning can be high or low and the entrant does not know this cost (but the incumbent does). In class, we found two pure-strategy Bayesian Nash Equilibria in this game. Assume that the probability that the cost of campaigning is high is a parameter p, 0 < p < 1. Show that when p is large enough, there is only one pure-strategy Bayesian Nash Equilibrium. What is it? What is the intuition? How large does p have to be?
