SHORT ANSWER

1. Explain what is meant by "asymmetric information." Identify and explain the two basic types of problems that arise when there is asymmetric information.

ANS:Asymmetric information is present when there is a difference in access to relevant information. Examples include information differences between (1) a worker and his employer, (2) a buyer and seller, and (3) an insured person and his insurer. The two basic types of problems are (1) moral hazard, which is a problem of hidden actions and ordinarily involves a principal and an agent, and (2) adverse selection, which is a problem of hidden characteristics or "lemons."

2. Explain how the presence of asymmetric information in car insurance markets may lead people who are good drivers or even average drivers to choose not to buy car insurance unless the law requires it.

ANS:Drivers (buyers and potential buyers of car insurance) know more about their driving habits than do the insurance companies (sellers of car insurance). The price of car insurance is likely to reflect the information asymmetry in that it incorporates more of a risk component than is really necessary to insure good and average drivers. Consequently, good and average drivers are priced out of the market and they rationally choose not to buy the insurance unless they are required to do so.

3. Explain the Condorcet paradox. To which type of voting system does it apply?

ANS:The Condorcet paradox applies directly to pairwise majority voting. It shows that even if individual voters' preferences exhibit transitivity, that property does not follow through to outcomes of pairwise majority voting. Consequently, the order in which choices are put up, in pairwise fashion, affects the final outcome. Using choices A, B, and C, it may be the case, for example, that under pairwise voting voters choose A over B and B over C, but then they may choose C over A. This result can obtain even when individual voters' preferences are transitive; hence, the paradox.

4. Assume there are two major political parties: the Conservatives and the Liberals. What does the median voter theorem imply about the nature of the platforms (that is, policy stances) of the Conservatives and Liberals?

ANS:The median voter theorem implies that political parties will set their platforms so as to appeal to the median ("middle of the distribution") voter. Therefore, rather than adopting extreme views, the Conservatives and Liberals will both adopt platforms that are toward the "middle of the road."

DIF: 2 REF: 22-2 NAT: AnalyticLOC: Understanding and applying economic models TOP: Median voter theoremMSC: Interpretive

5. How have insights from the field of psychology influenced the thinking of economists in recent years?

ANS:Insights from psychology have led some economists to question the assumption of rationality that pervades mainstream economic models. Evidence from experimental economics does raise serious questions about the rationality assumption. For example, most people may be concerned with the fairness of outcomes, in addition to the impact of those outcomes on their own well-being. An open question is: If the rationality assumption does not really reflect the behavior of real economic actors, then how important is it that we model other motivations, such as the desire for fairness, the tendency to procrastinate, overconfidence, etc.?

34. A radio story reported a study on the makes and models of cars that were observed going through intersections in the Washington, D.C. area without stopping at the stop signs. According to the story, Volvos were heavily overrepresented; the fraction of cars running stop signs that were Volvos was much greater than the fraction of Volvos in the total population of cars in the D.C. area. This is initially surprising because Volvo has built a reputation as an especially safe car that appeals to sensible, safety-conscious drivers. How is this observation best explained?a. Volvo drivers are not willing to take risks that they would take in another, less safe car. Driving a

Volvo leads to a propensity to run stop signs.b. Volvo drivers are not willing to take risks that they would take in another, less safe car. Driving a

Volvo reduces the propensity to run stop signs.c. Volvo drivers are willing to take risks that they would not take in another, less safe car. Driving a

Volvo reduces the propensity to run stop signs.d. Volvo drivers are willing to take risks that they would not take in another, less safe car. Driving a

If Rhonda rejects the allocation, the professor keeps the $10, and each student receives nothing. Rudy selects $9 for himself and $1 for Rhonda. Based on the studies of human decision making, which of the following statements is correct?a. If Rhonda accepts the offer, she is behaving rationally.b. If Rhonda rejects the offer, she may value fairness more than $1.c. If Rhonda rejects the offer, Rudy made a bad choice by trying to keep $9 for himself.d. Any of the above could be correct.

31. Brian and Andrea are playing the ultimatum game, starting with $100. The coin flip results in Brian being the one to propose a division of the $100. Brian proposes that he gets $99 and Andrea gets $1.a. Because the 99-1 split isn’t fair, Brian should not make this offer.b. Conventional economic theory predicts that Brian will propose a 99-1 split, just as he did.c. Experimental evidence suggests that Andrea will accept the 99-1 split because, even though it isn’t

fair, it’s better than nothing.d. Economic theory predicts that Brian should choose a 60-40 split to maximize his payoff.
