CHAPTER 11
25). You are the mayor of a town with 20,000 residents. The head of your economic development agency recently
conducted a survey in which the 20,000 residents said that a small public library in the center of town would
be worth $40 to each of them. Because the cost to build the library is only $500,000, you arrange to have the
library built. Everyone in town enjoys the library, but when you asked for donations to pay for the library, you
only collected $100,000. You are convinced that
a. the survey must have overstated how much the library was worth to each resident; otherwise, you
would have collected $500,000 in donations.
b. the cost of the library exceeded the social benefits.
c. the library was an example of the Tragedy of the Commons.

26). You are the mayor of a town with 20,000 residents. The head of your economic development agency recently
conducted a survey in which the 20,000 residents said that a small public library in the center of town would
be worth $40 to each of them. The cost to build the library is $500,000. Which of the following is the most
efficient option?
a. The library should be built and paid for with donations collected from residents, as these donations
should more than cover the cost of the library.
b. The library should be built and paid for by the town government and paid for with a tax on the
residents because all residents would benefit from it but some residents would not donate if they
were asked.
c. The library should be built and paid for by the wealthiest ten percent of the residents.
d. The library should not be built.
27). Highway engineers want to improve a dangerous stretch of highway. They expect that it will reduce the risk

$109,200.
$274,500.
$1.6 million.
