Question 3 Consider a sealedbid second price auction with two bidders. The seller has a value 0 for the object. Each bidder has a value drawn from the uniform distribution FCv) = 1; on [0, 1], i.e., the probability that his value is less than I is just 2:. a. Given that the highest bidder has a value try, you know how to calculate the expected value UL of the lower bidder, conditional on this value being less than my. Calculate the expected revenue of the seller. b. Now suppose the seller can also submit a bid 1", which is his reservation price. If the highest bid is lower than r, then the object is not sold. If the highest bid is greater than r, then the highest bidder gets the object at a price equal to the larger of the other two bids. For an arbitrary r, what is the probability that: [i] Both buyers bids exceed r (ii) Exactly one buyer bids more than r (be careful with your calculations), (iii) Both buyers bid less than r? c. From part b., calculate the sellers expected revenue for an arbitrary reserve value. d. Find the optimal reserve
