Microeconomics, 9e (Pindyck/Rubinfeld)Chapter 19 Behavioral Economics19.1 Reference Points and Consumer PreferencesIn traditional economic theory, consumers are assumed to be rational, which means that they:A) attempt to maximize utility, subject to a budget constraint, and they do so with a limited knowledge about prices.B) have full knowledge of prices and attempt to maximize utility, subject to a budget constraint.C) look to maximize utility, often without regard to income or prices.D) behave in unpredictable but observable ways of choosing goods and services.Answer: BDiff: 1Section: 19.1In traditional economic theory, producers are assumed to be rational, which means that they:A) attempt to maximize profit with a limited knowledge about input prices.B) have full knowledge of input prices and attempt to maximize profit in both the short- and the long-run.C) look to maximize profit, often without regard to input prices or available technologies.D) behave in unpredictable but observable ways of producing goods and services.Answer: BDiff: 1Section: 19.1Based on the assumptions of traditional economic theory,A) we conclude that it is not possible to derive demand curves for consumers or cost curves for producers.B) we construct a theory of consumer and producer behavior described by demand and cost curves, which assume that consumers and producers make decisions based on all available information.C) we build theories that work, even when we assume a lack of perfect knowledge on the part of consumers and producers.D) we build demand and cost curves that may behave in unpredictable ways, because we can't assume that consumers and producers make decisions based on all available information.Answer: BDiff: 1Section: 19.1In the field of Behavioral Economics, we challenge the concept that:A) consumers behave in the manner described by the constrained maximization problem.B) firms have incomplete knowledge of production technologies.C) firms choose combinations of labor and capital that may not minimize cost.D) psychological factors have little to do with consumer and producer decisions.Answer: ADiff： 1Section: 19.16) Refer to Figure 19.2.1 above. Which of the following statements is true?A) The price of a shovel increases to $40 during a snow storm, and Qj units are sold.B) The price of shovels increases to $25 during a snow storm, and the quantity sold would range between Ql and QzThe price of shovels during a snow storm remains at $20, but quantity demanded increases to Q2units.C) An increase in the price of shovels, from $20 to as much as $40, is considered fair during a snow storm. Answer: BDiff: 1Section: 19.2Refer to Figure 19.2.1 above. Consumers understand why the price of shovels would increase somewhat during a snow storm and would be willing to buy at higher prices. Which demand or portion of a demand curve best reflects that statement?A) The demand curve DjThe flat portion of demand curve D27) The dashed portion of demand curve D2The steep, solid portion of 诙Answer: BDiff: 1Section: 19.2Refer to Figure 19.2.1 above.

Due to the perceived fairness of price increases during a snow storm, the demand curve:A) is very elastic at prices above $25.B) is very inelastic at prices above $25.C) is elastic for price decreases but inelastic for price increases.D) is inelastic throughout its entire range.Answer: ADiff: 1Section: 19.2In the ultimatum game, the basic theory of utility would suggest that the optimal distribution of $100 is, for you and the stranger, respectively:A) $99; $1.B) $50; $50.C) $67; $33.D) none of the aboveAnswer: ADiff： 1Section: 19.29) When the ultimatum game is played experimentally, the typical range of proposals for sharing $100 between you and the stranger is,$99; $1 and $50; $50.A) $67; $33 and $50; $50.B) $67; $33 and $99; $1.C) none of the aboveAnswer: BDiff： 1Section: 19.210) In the efficiency wage theory of labor, an increase in wages is justified by a resulting:A) increase in the workers1 standard of living.B) increase in the attractiveness of the work environment.C) increase in productivity and the desire to work harder.D) all of the above.Answer: CDiff: 1Section: 19.2In the e仔iciency wage theory,A) fairness directly affects worker productivity.B) fairness concerns do not apply.C) fairness has a mixed influence on productivity.D) fairness and wage increases depend on the level of employment.Answer: BDiff: 1Section: 19.211) Business firms have an easier time explaining price increases when those price increases are in response to:A) higher costs.B) higher demand.C) unfair taxation.D) a lack of competition.Answer: ADiff: 1Section: 19.2In the basic model of consumer behavior, A) fairness cannot be explained.B) fairness depends more on income than on preferences.C) fairness is manifested by the consumers* willingness to pay.D) a reduction in demand and market price can be the result of even one consumer who perceives that prices are unfair.Answer: CDiff： 1Section: 19.2Using a traditional labor market explanation of the influence of fairness, we would assert that: A) the dissatisfaction with unfair wages by just one or few workers is su仔icient to push wages up. B) unemployment caused by the imposition of minimum-wage laws is fundamentally unfair.C) workers do not complain about unfair wages if there is a glut of unemployed workers.D) if enough workers do not feel that their wages are fair, there will be a reduction in the supply of labor, and wage rates will increase.Answer: DDiff： 1Section: 19.219.3 Rules of Thumb and Biases in Decision Making1) People resort to rules of thumb to make complex decisions, especially: A) if they have a good understanding of the factors involved.B) when they have little experience with the issue at hand.C) when the market system does not function freely.D) when issues of fairness are involved.Answer: BDiff： 1Section: 19.3The basic model of consumer behavior does not include rules of thumb, mainly because: A) the model is biased against hard rules.B) the model does not believe that consumers are fully informed.C) it does not allow for biases to be introduced in our economic decision making.D) it allows for benchmarks that replace rules of thumb.Answer: CDiff: 1Section: 19.32) In understanding the concept of anchoring, which two factors play an essential role?A) Price and quantity of equilibriumIncome
