Two types of existing houses are for sale: ones with a cracked foundation and ones
without. In all other respects, they are identical. Houses without cracked foundations
are worth $200,000 while those with cracked foundations are worth $200,000 minus the
$20,000 to fix the crack or $180,000. The frequency of solid foundations is 80%.
Sellers know which type of house they have but buyers cannot detect a crack. No seller
“must” sell his house in order to move and thus no one accepts anything less than its
value.
Suppose some of the owners with solid foundations remove their homes from the
market because they can’t sell for a price that is as high as the value of their homes.
Then
A. the buyers’ reservation price rises.
B. the owners of cracked slabs also begin to remove their homes from the market.
C. the proportion of homes for sale with a cracked slab rises.
D. the buyers become more willing to believe the owners’ claim of a solid foundation.
