Exercise 15 A city is considering how much to spend to hire people to monitor its parking meters. The
following information is available to the city manager:
Hiring each meter monitor costs $10,000 per year.
With one monitoring person hired, the probability of a driver getting a ticket each time he or she parks
illegally is equal to .25.
With two monitors, the probability of getting a ticket is .5; with three monitors, the probability is .75;
and with four, it’ equal to 1.
The current …ne for overtime parking is $20.
Assume …rst that all drivers are risk neutral. What parking …ne would you levy, and how many
meter monitors would you hire (1, 2, 3, or 4) to achieve the current level of deterrence against illegal parking

Now assume that drivers are highly risk averse. How would your answer to (a) change? 2 3 Critical Thinking Exercise 16 (a). Four USC students must decide on which two of them will be roommates in a dorm. The

Student 1 : Student 2 > Student 3 > Student 4; Student 2 : Student 4 > Student 1 > Student 3; Student 3 : Student 1 > Student 2 > Student 4; Student 4 : Student 1 > Student 2 > Student 3: If you are the administration manager who aims to design an optimal matching scheme for this group of
students. What is your decision of allocating these students?
(b). Now consider another 4 students with the following preferences:
Student 1 : Student 2 > Student 3 > Student 4; Student 2 : Student 3 > Student 1 > Student 4; Student 3 : Student 1 > Student 2 > Student 4; Student 4 : Student 1 > St...
