TRUE/FALSE
1. The science of economics is a finished jewel, perfect and unchanging.
2. In economics, a difference in access to relevant knowledge is called a behavioral asymmetry.
3. Informational asymmetry may apply to a hidden action or hidden characteristic where the informed
party may be reluctant to reveal relevant information.
4. An example of asymmetric information is when a seller of a house knows more than the buyer about
the house’s condition.

ees is to pay them in advance for their work.
11. In the employer-worker relationship, the employer is regarded as the "principal" and the worker is
regarded as the "agent."
12. In a moral hazard problem, the agent is unable to perfectly monitor the principal’s behavior so the
principal applies less effort than the agent considers desirable.
13. One way that employers respond to the moral-hazard problem is by monitoring their employees.
Chapter 22/Frontiers in Microeconomics ❖ 75
14. The moral hazard problem and the desire of firms to lessen that problem serve as a plausible expla-

principal-agent problem.

involves hidden actions while adverse selection involves hidden characteristics.

valid set of social preferences.
30. The Condorcet paradox tells us that, even though it is impossible to satisfy all of Arrow’s properties
of a desirable voting system, pairwise majority voting will always satisfy transitivity.
31. Borda count is a voting method often used in polls that rank sports teams.

32. Arrow’s impossibility theorem demonstrates the impossibility of the median voter theorem.
33. Arrow's impossibility theorem shows that it is impossible to find a better voting system than pair-
wise majority voting.
34. Arrow’s impossibility theorem illustrates the difficulties in creating the perfect voting system.
35. Arrow’s impossibility theorem states that the majority rule fails to produce transitive preferences for
society.
36. The unanimity property states that the ranking between any two outcomes should not depend on
whether some third outcome is available.
