A reserve price is а minimum price set by the аuctiоneer. If nо bidder is willing tо pаy the reserve price, the item is unsold at a profit of $0 for the auctioneer. If only one bidder values the item at or above the reserve price, that bidder pays the reserve price. An auctioneer faces two bidders, each with a value of either $20 or $50, with both values equally probable. What reserve price should the auctioneer set, and what is the expected revenue from auctioning the item with and without a reserve price? Hint: Considering two bidders and two possible outcomes for each bidder, think about the four possible combinations of bids that the auctioneer could receive.
