First Fiddler's Bank has foreclosed on a home mortgage and is selling the house at auction. There are three bidders for the house, Ernie, Minnie, and Betsy. First Fiddler's does not know the willingness to pay of these three bidders for the house, but on the basis of its previous experience, the bank believes that each of these bidders has a probability of 
of valuing it at $700,000, a probability of 
of valuing at $400,000, and a probability of 
of valuing it at $300,000. First Fiddler's believes that these probabilities are independent among buyers. If First Fiddler's sells the house by means of a second-bidder, sealed-bid auction (Vickrey auction), what will be the bank's expected revenue from the sale? (Choose the closest option.)

A first edition of Adam Smith's Wealth of Nations (published in 1776) is being auctioned via the Internet. The current owner starts by posting his own "bid" for it. Bidders are allowed to submit bids at any time during a one-week interval. For the following week, bids will be accepted only if they exceed the currently posted high bid. Throughout the week, the highest bid that anyone has made so far will be posted. At the end of the week, the book will be sold to the highest bidder at the price that he or she bid for it. Assuming that bidders understand the rules of the auction, the outcome of this auction will be similar to that for
A) an English auction with a reserve price equal to the owner's bid.
B) a Dutch auction with a reserve price equal to the owner's bid.
C) a sealed-bid auction in which the book is sold to the highest bidder at the highest bidder's bid price.
D) a common-value auction.
E) an English auction with no reserve price.
A) an English auction with a reserve price equal to the owner's bid.

A stamp dealer is holding an auction for an English Penny Black postage stamp, issued in 1840. Potential buyers are asked to submit written bids for this stamp, and it will be sold to the highest bidder at a price equal to the bid submitted by the second-highest bidder. If bidders understand the logic of this auction and bid in their own self-interest,
A) bidders will shade their bids by approximately 10%, and hence the stamp will be sold for about 10% less than the second-highest willingness to pay.
B) bidders will bid more than their true valuation, since they only have to pay the second-highest bid and not their own bid.
C) bidders will bid exactly their true valuation.
D) the highest bidder will overstate his valuation and the second-highest bidder will understate his valuation.
E) bidders will all bid (n 2) of their true valuations, where n is the number of bidders.

The profit-maximizing strategy for a bidder in a Vickrey auction where there are common values for the object being sold is to bid less than her estimated value for the object, and the more bidders there are, the more the profit-maximizing bidder should shade her bid below her estimated value.

Herb's Auction House in Purloined Hubcap, Oregon, holds sealed-bid used-car auctions every Wednesday. Each car is sold to the highest bidder at the second-highest bidder's bid. On average, two-thirds of the cars that are auctioned are lemons and one-third are good used cars. A good car is worth $1,500 to any buyer. A lemon is worth only $150 to a buyer. Most buyers can do no better than random at picking good cars from the lot. There is only one exception, Al Crankcase. Al can sometimes but not always detect lemons by means of a subtle test. A good car will never fail Al's test, but approximately half of the lemons fail his test. Al attends every auction, tests every car, and always bids his expected value. Normal bidders bid less than the expected value for a randomly selected car but more than the value of a lemon.
A) Al will bid $825 for cars that pass his test and $150 for cars that fail his test. Normal bidders will get only lemons.
B) Al will bid $750 for cars that pass his test and $500 for cars that fail his test. Normal bidders will get only lemons.
C) Al will bid $500 for cars that pass his test and $150 for cars that fail his test. Normal bidders will get good cars onlyof the time.
D) Al will bid $600 for cars that pass his test and $250 for cars that fail his test. Normal bidders will get good cars onlyof the time.
