Correct Answer: B II. Short Answer/Essay Questions 1. Briefly describe what we mean by the word “incentive” as it is used in economic analysis.
Give examples to illustrate your answer. Suggested Answer: An incentive is a device designed to try to get people to do more of a good thing or less of a bad thing. For example, bonuses are sometimes paid to employees as a means to encourage them to be more productive (a good thing). In other cases, we use fines to discourage such behaviors as illegal parking (a bad thing). 2. How does a moral incentive differ from an economic incentive? Suggested Answer: A moral incentive appeals to one’s conscience while an economic incentive appeals to one’s financial or economic well being. 3.
Referring to the example in the book regarding the day-care center and the problem of parents picking up their children late, why did charging a fee to parents for picking up children late cause parental tardiness to increase? Suggested Answer: Charging a fee for tardiness had the effect of replacing a moral incentive, i. e. , it’s not polite to be late, with a small economic incentive, i. e. , a fine. In effect, the fee (fine) placed a price on being late. Because the fee was relatively low, and obviously lower than the “cost” incurred when the parent was considered impolite, more parents were willing to pay it. 4.
According to Freakonomics, economics is the study of incentives. Explain this statement. Suggested Answer: Economists study, among other things, the choices people, e. g. , consumers and firms, make. They make these choices based on the incentives they face. Therefore, to understand incentives is to better understand an individual’s choices. 5. Does a string of correct answers on a test, duplicated by several students in the same class, prove the teacher is cheating? Why or why not? Suggested Answer: No. A string of the same answers may be evidence of a cheating teacher, but not proof. There are other possible explanations for this.
For example, it could simply be coincidence. Alternatively, it could be that all of the questions involved are easy and the students are all exceptionally bright. 6. Why did some Chicago public school teachers cheat to increase their students’ test scores? Suggested Answer: Teachers are rewarded or punished depending on how their students perform on standardized tests. This reward/punishment structure in turn created incentives for teachers to cheat. Some teachers responded to those incentives by cheating. Others did not. 7. Briefly, how did Levitt arrive at the conclusion that some sumo wrestlers were cheating?
Suggested Answer: Given an individual wrestler’s records, he predicted whether the wrestler would win the next match. He did this for wrestlers who were “on the bubble. ” He concluded that cheating was likely when a wrestler won with significantly greater frequency than his record would indicate. 8. Explain, using economic principles, why Levitt expected cheating to be more likely when a wrestler on the bubble, i. e. , with a 7-7 record, was competing against a wrestler with an 8-6 record than when the same wrestler was competing with someone with a 10-4 record.
Suggested Answer: To answer this, we need to consider benefits and costs. The benefits to the wrestler on the bubble are obvious. An eighth win would ensure that he would not drop in the standings. For the 8-6 wrestler, the cost of losing would be minimal because his ranking would not drop, while winning probably would not move him up. However, the cost of not winning is much higher for the 10-4 wrestler because he has a good chance of winning the tournament with an 11-4 record or at least getting a substantial bonus.
Thus, in the first case, the combined benefits of cheating outweigh the combined costs, while in the second case just the reverse is true. 9. Referring to Paul Feldman’s bagel business, use economic principles to explain why cheating would be more likely in an office with a few hundred employees than it would be in an office with a few dozen employees. Suggested Answer: In this case, the benefits from cheating are the same in both cases, i. e. , a free bagel, so we need to focus on the expected costs of cheating. Consider first the likelihood that someone who cheats will get caught.
With so many hands reaching for bagels and dropping money in the box, it is harder to detect an individual who does the former, but not the latter, than it would be when there are only a few employees present. Hence, the probability of getting caught is likely lower in the large office than it is in the small office. Second, the cost of getting caught is greater the fewer the number of employees because of the social costs that come with getting caught, i. e. , the shame factor. Fellow employees are more likely to know the thief in the small office than in the large office.
These two factors combine to reduce the costs of cheating in the large office compared to the small office, with the result that the net benefits from cheating in the large office are greater.

Correct Answer: C II. Short Answer/Essay Questions 1. How did the exposure of the Ku Klux Klan’s secrets significantly diminish
the Klan’s presence and influence in society? Suggested Answer: The Klan had been powerful prior to the exposure of its secrets because it controlled information on when and where it would strike next. Not knowing who the next victim would be severely constrained the actions of most blacks and people who tried to help them who feared they could be the Klan’s next target. In addition, the Klan has been able to keep its illegal actions from having legal consequences. It was able to do this because the membership was loyal to the organization and had secret means of communicating.
Without these secret means it was more likely that someone would expose the Klan’s illegal activities and individual members would have to bear the legal consequences of those activities. 2. Briefly evaluate the following statement indicating whether you agree or disagree with the statement and why. “How a seller (or real estate agent) describes a house that is on the market is unimportant. Once the prospective buyers sees the house, they will make up their minds, regardless of what was written or said. ” Suggested Answer: In determining the sales price or interest in a house, how it is described is very important.
For the majority of prospective buyers this initial information is critical to their decision whether looking over a house is worth their time. 3. What does the exposure of secret or hard-to-find information do to the institution that had maintained that informational advantage? Give an example of where this has occurred in the past few years. Suggested Answer: Once that information is made public, i. e. , once the information asymmetry disappears, the advantage the institution had previously maintained is weakened or eliminated. This in turn makes the institution less powerful and less able to take advantage of the uninformed.
The text cites the example of what happened to the price of term life insurance once pricing policies and prices offered by different companies were made available in one common location, i. e. , the Internet. Almost immediately, the advantage individual firms had previously possessed relative to potential customers disappeared, causing prices to fall by a considerable amount. 4. Short of outright lying, how can an ordinary person abuse information? Give an example. Suggested Answer: By withholding important information or by combining information in such a way that it tells a distorted tale.
For example, the analysis of the Internet dating scene tell us that people tend to exaggerate their qualities to make themselves sound better than they really are. 5. In constructing the model of supply and demand and the model of perfect competition, it is assumed that buyers and sellers have perfect information. What happens to the outcome in a market, compared to the competitively determined outcome, when this assumption no longer holds? Suggested Answer: When constructing the basic model of supply and demand, we assume perfect information on the part of both buyers and sellers.
As such the demand curve represents the buyer’s true willingness and ability to pay. However, imperfect information limits the ability of buyers to determine their true willingness to pay. It also inhibits sellers, e. g. , people selling a home, who fear they are not receiving the maximum possible price. The result is that, in certain situations, the item in question may not in fact go to the party who values it most. A less-than-efficient outcome results.

Which of the following best explains why crack dealers were able to sell so much crack for so long? a)Because it was so cheap and addictive, viewed from the customer’s perspective there were few if any viable substitutes.
b)The incomes of drug users, and hence demand for drugs, increased dramatically in the 1970s. c)Police departments avoided going after crack dealers and users for fear of being labeled as racists. d)The C. I. A was covertly supporting the dealers’ efforts. Correct Answer: A 23.

Correct Answer: D
24. As the market for crack cocaine expanded, the number of dealers expanded dramatically as well. Assuming the quality of crack is relatively uniform across suppliers, as the number of suppliers increased relative to demand, we would predict that the profits of individual dealers would: a)increase. b)increase or stay the same. c)stay the same. d)decrease. Correct Answer: D II. Short Answer/Essay Questions 1. Define the term “conventional wisdom. ” Use examples to illustrate your answer. Suggested Answer: Conventional wisdom refers to the unquestioned belief most people use to explain a social or economic phenomenon.
Alternatively, conventional wisdom can be used to refer to some set of “facts” about a particular situation that people conveniently assume are true. For example, it is commonly believed that people get involved in dealing drugs because it is highly profitable for everyone involved in dealing. As another example, many people believe that because the typical college professor only teaches 2-3 courses per week, he only works 6-9 hours per week. 2. According to Levitt and Dubner, the organizational structure of the Black Gangster Disciple Nation is extremely similar to that of McDonald’s.
Describe the relevant similarities between the two organizations and explain how the organizational structure affects the incentives workers at the lower levels face. Suggested Answer: In each organization, relatively few employees have high-level jobs, but those who do are richly compensated. The vast majority of employees in both organizations are located at the bottom of the pyramid and make relatively low wages. However, the high wages paid to upper management in both organizations act as an incentive to make lower level employees work harder in hopes that they will be able to ascend the corporate ladder.
That being said, relatively few employees are successful in the “tournament” and most never rise above their initial level of employment. 3. Briefly describe a “tournament” form of labor market. Suggested Answer: A “tournament” form of labor market is a labor market in which there are many capable workers and only a few highly desirable jobs, i. e. , the supply of workers exceeds demand. The few jobs pay very well. Therefore, it is like a tournament because only the winner gets the prize, though many compete. 4. List the four factors which, according to Levitt and Dubner, determine a wage.
In addition, explain the effect each factor has the wage paid to a particular type of labor. Suggested Answer: The four factors include (1) the number of people willing and able to do the job, (2) the specialized skills the job requires, (3) the unpleasantness of the job, and (4) the demand for the good or service the worker produces. All else constant, an increase in the number of people who are willing to do the job causes the wage rate to fall. In contrast, an increase in the specialized skills the job requires, the unpleasantness of the job, and the demand for the good or service the worker produces all cause the wage rate to increase.
5. Assume there is an increase in the demand for a service produced by a particular group of workers. All else constant, how should we expect this to affect the wage earned by those workers? Why? Suggested Answer: An increase in demand for the service produced by a particular group of workers would cause the price paid for the service to increase (the increase in demand causes excess demand at the initial price, which in turn causes market price to increase). As the price of the service produced increases, so does the value of the worker’s output to the firm.
This in turn makes the worker more valuable and the demand for workers increases, causing the wage to rise as well. 6. Graphically illustrate the effect the introduction of crack cocaine had on the market for the type of high offered by cocaine and similar drugs. Suggested Answer: Assuming the demand and supply curves have the usual shape, the introduction of crack cocaine into the market would cause the supply curve to shift right, both because of an increase in the number of sellers of this type of high and because of the lower production costs associated with crack.
The resulting excess supply at the initial equilibrium price causes market price to fall until equilibrium is reestablished in the market. Chapter 4 Where Have All the Criminals Gone? I. Multiple-Choice Questions 1. Which of the following was not part of Communist dictator Ceausescu’s strategy to modernize the Romanian economy? a)He favored manufacturing over agriculture. b)He set an example of self sacrifice for the rest of the population. c)He made abortion illegal. d)He used economic incentives (taxes) to encourage fertility among women. Correct Answer: B 2.
Economically, Ceausescu’s ban on abortion was intended to: a)free up medical resources to provide alternative forms of health care. b)facilitate increased production in the agricultural sector of the economy. c)provide a source of increased demand for goods and services and hence, stimulate economic growth. d)increase the population and, consequently, the supply of labor. Correct Answer: D 3. One of the major consequences on Ceausescu’s ban on abortion and emphasis on increased fertility among women was: a)a dramatic increase in the population and corresponding decrease in the standard of living for most Romanian citizens.
b)a dramatic decrease in the population and corresponding increase in the standard of living for most Romanian citizens. c)a dramatic increase in the population and corresponding increase in the standard of living for most Romanian citizens. d)a dramatic decrease in the population and corresponding decrease in the standard of living for most Romanian citizens. Correct Answer: A 4. What do the overthrow of the Ceausescu regime and the decrease in crime in the United States in the 1990s have in common? a)They were both the result of a dramatic increase in the level of unemployment in each country.
b)They can both be explained, in large part, by abortion policies enacted in each country several years earlier. c)They both precipitated recessions in the respective countries. d)There is no reasonable explanation for either event. Correct Answer: B 5. Which of the following is not a possible economic explanation of how increased reliance on prisons leads to a decrease in crime? a)As more criminals are put in jail, the supply of criminals, and therefore crime, decreases. b)As more criminals are put in jail, it causes the benefits from crime available to the criminals who remain on the street to increase.
c)As the sentence a person receives for committing a crime increases, so does the cost of committing the crime. All else constant, this causes the efficient amount of crime to go down. d)Seeing other people put in jail reduces the incentive for would-be criminals to actually engage in crime. Correct Answer: B 6. Which of the following is not one of the frequently cited explanations for the decline in crime that occurred in the 1990s? a)The use of innovative policing strategies. b)Tougher gun control laws. c)Increased reliance on more lenient sentencing practices (i.
e. , less reliance on prisons). d)Changes in crack and other drug markets. Correct Answer: C 7. Which of the following explanations for the drop in crime that occurred in the 1990s is not supported by the data? a)A strong economy. b)Increased reliance on prisons. c)An increase in the number of police. d)Changes in illegal drug markets. Correct Answer: A 8. Which of the following explanations for the drop in crime that occurred in the 1990s is supported by the data? a)A strong economy. b)Increased reliance on prisons. c)The increased use of capital punishment.
d)The use of innovative policing strategies. Correct Answer: B 9. The observation that “crime rates tend to be high when imprisonment rates are high” led some criminologists to conclude that crime rates would fall if imprisonment rates were lowered. This is an example of: a)confusing correlation with causation. b)positive economic analysis. c)normative theory. d)the argument that incentives matter. Correct Answer: A 10. The increased use of prisons accounted for approximately _____________ of the drop in crime experienced in the 1990s. a)one tenth b)one quarter c)one third
d)one half Correct Answer: C 11. Which of the following best explains why the increased use of capital punishment has not contributed to the decrease in crime? a)Individuals who commit capital crimes believe life is not worth living. Therefore, they view capital punishment as a benefit rather than a cost. b)Only two percent of all criminals on death row are actually executed in a given year. As such, from the criminal’s perspective the expected cost of the death penalty is quite low. c)From the criminal’s perspective, the benefits of a capital crime always outweigh the costs.
d)The supply of capital crimes is perfectly inelastic. Therefore, the cost of committing the crime is irrelevant. Correct Answer: B 12. There is strong evidence supporting the argument that increasing the number of police reduces crime. From the economist’s perspective, additional police should be hired up to the point at which: a)the additional benefits from hiring one more police officer equal the additional cost incurred. b)the total benefits from hiring police are maximized. c)the crime rate is reduced to zero. d)the marginal cost of hiring one more police officer is zero. Correct Answer: A
13. Which of the following is evidence that innovative policing strategies were not, in fact, responsible for the decrease in crime in New York in the 1990s? a)Crime in New York had started to fall in 1990, four years before such strategies were implemented. b)Between 1991 and 2001, the NYPD grew by 45 percent. c)Crime fell everywhere in the 1990s. Many cities didn’t employ any innovative strategies. d)All of the above. Correct Answer: D 14. Which of the following statements is false? a)Research shows that the high homicide rate in the United States is due, in part, to ready availability of guns.
b)Depending on who possesses a gun when an altercation takes place, the existence of the gun may lead to either more or less violence. c)There are more guns than there are adults in the United States. d)Gun control laws contributed significantly to the drop in crime that occurred in the 1990s. Correct Answer: D 15. Which of the following best explains why gun control laws such as the Brady Act have had little or no effect on crime rates? a)Guns are not a significant factor in crime. b)Criminals view the black market for guns (which is unaffected by such laws) as a near perfect substitute for the legal gun market.
c)Such laws have caused the price in the black market for guns to dramatically increase. d)Police routinely refuse to enforce such laws. Correct Answer: B 16. All of the following are explanations why gun buyback programs fail to reduce crime except: a)the price offered is less than the benefits the criminal receives from using a gun when committing a crime. b)there is virtually no effect on the supply of guns that remain available to potential criminals. c)the guns turned in during such programs are generally not the types of guns used by criminals.
d)criminals use the money they get from participating in such programs to buy better guns. Correct Answer: D 17. Which of the following statements regarding economist John Lott Jr. ’s hypothesis that “right-to-carry” laws have reduced crime in areas governed by such laws is correct? a)There is strong evidence in support of his hypothesis. b)While Lott produced strong evidence in support of his hypothesis, other scholars have been unable to reproduce his results, which casts doubt on his findings. c)Lott failed to produce any empirical evidence in support of his hypothesis.
d)While Lott produced evidence supporting his hypothesis, he nonetheless argues that gun ownership should be severely restricted. Correct Answer: B 18. For many individuals growing up on the South Side of Chicago, a career in crack dealing: a)was the best job they had access to. b)was not nearly as difficult as passing an economics class. c)was only available to an extremely small number of people. d)was a relatively easy means to earn a considerable amount of income in a short amount of time. Correct Answer: A 19. Which of the following is the primary explanation for the decline in crime among crack dealers in the 1990s?
a)The huge decline in the profits from selling crack. b)The innovative policing strategies employed by police departments around the country. c)A dramatic decrease in the number of crack dealers. d)A large decrease in the demand for crack. Correct Answer: A 20. The profits crack dealers were able to earn declined in the 1990s primarily as a result of: a)a decrease in demand for crack. b)the use of innovative policing strategies by police departments around the country. c)an increase in competition among crack dealers. d)a general improvement in the economy. Correct Answer: C 21.
Based on available data, the majority of the crime that occurs in the United States is committed by males between the ages of 16 and 24. Moreover, a relatively small subset of males of a given age is responsible for the majority of crime committed by males of that age. These data suggest that, all else constant: a)efforts to reduce crime should be focused primarily on young males. b)a decrease in the percentage of young males in the population should result in a decrease in crime rates. c)Locking up older criminals for long periods of time is probably not a very effective way to deter crime. d)all of the above. Correct Answer: D 22.
According to a study by Donahue and Levitt, the precipitous decline in the homicide rate in the 1990s was largely a result of: a)a change in the demographics of Americans, resulting in a higher average age. b)abortions performed during the 1970s. c)a significant uptick in economic activity. d)innovative police strategies, beginning in New York. Correct Answer: B 23. The argument that the legalization of abortion is a primary factor in the explanation of the decrease in crime in the 1990s is an example of: a)normative economic analysis. b)counterfactual economic analysis. c)positive economic analysis. d)immoral economic analysis.
Correct Answer: C 24. Which of the following statements best describes the logic supporting the hypothesis that the legalization of abortion led to a decrease in crime roughly 18 years later? a)The increase in abortion caused a decrease in the population and, consequently, the number criminals. b)The increase in abortion caused a reduction in the percentage of the population accounted for by young males (the segment of the population most likely to commit crime), as well as the number males born into dysfunctional families. c)Because abortion had been illegal, legalizing it naturally caused crime to decrease.
d)The type of woman who gets an abortion invariably gives birth to children who turn to crime as they get older. Correct Answer: B II. Short Answer/Essay Questions 1. Use basic economic principles to explain how each of the following would result in a decrease in crime. a. An increase in the number of police in a city. b. Increased reliance on prisons to punish criminals. Suggested Answer: An increase in the number of police officers increases the likelihood that a criminal will be caught and punished. This in turn increases the likely cost the person who commits a crime will incur.
Holding the benefit from the crime constant, it is then reasonable for the rational person to engage in less crime. An increased reliance on prisons to punish criminals has a similar effect. In this case, the expected cost to the criminal is increasing because the cost associated with punishment is greater. The same conclusion applies. 2. Explain, using basic economic concepts, why capital punishment has not had a measurable effect on the amount of crime in the United States. Suggested Answer: The purpose of punishment for a crime is to increase the cost to the person who commits the crime.
Obviously, being put to death constitutes a rather severe cost to most people. However, when we consider that only 2 percent of persons on death row are actually executed each year, the perceived, or expected, cost of committing a capital crime is much less, especially when compared to the benefits the person expects to gain from committing the crime. So long as the expected benefits exceed the expected costs, it is rational for the person to continue to commit the crime. 3. Explain how gun control laws, e. g. , the Brady Act, affect the equilibrium in the black market for guns.
Suggested Answer: Gun control laws make it more costly for certain individuals—both buyers and sellers—to compete in the legal market for guns. As such, both demand for and supply of guns in black market could be expected to increase. All else constant, this would have the effect of causing the equilibrium quantity of guns exchanged to increase, while the effect on equilibrium price would be uncertain without more specific information on the magnitude of the shift in each curve. 4. Explain how competition among crack dealers contributed to the decrease in crime that occurred in the 1990s.
Suggested Answer: As competition increased, individual dealers reduced the price they charged for their product. This in turn led to a decrease in total revenues, but costs did not change. As such, profits fell. This left dealers less inclined to engage in criminal acts such as retaliation against competitors because the costs of such acts were now higher relative to the potential benefits. 5. Describe the study by Donahue and Levitt which examines the link between the legalization of abortion and the decline in crime rates that began to appear roughly 18 years later.
In particular, does their study provide a viable explanation for the decline in crime rates that occurred in the 1990s? If so, what is it? Suggested Answer: Approximately one half of the reduction in crime rates that occurred in the 1990s is accounted for by the legalization of abortion in 1973. Chapter 5 What Makes a Perfect Parent? I. Multiple-Choice Questions 1. Which parenting author believed that an infant’s brain is growing so much that overstimulation might cause “a great deal of harm,” and cautioned parents that their child is not a “plaything”? a)L.

At the same time, 3 boaters die as a result of being struck by lightning for every 100,000 days spent boating and 2 million days are spent boating each year. Which of the following statements is correct? a)The probability of dying as a result of a hunting accident is greater than probability of dying as a result of being struck by lightning while boating.
b)The probability of dying as a result of being struck by lightning while boating is greater than the probability of dying as a result of a hunting accident. c)The probability of dying as a result of a hunting accident and the probability of dying as a result of being struck by lightning while boating are the same. d)None of the above Correct Answer: B 10. Peter Sandman, a self-described “risk communications consultant,” was once quoted as saying, “The basic reality is that the risks that scare people and the risks that kill people are very different”?
What did Sandman mean by this statement? a)People are usually incapable of assessing risks of any type. b)People are much more frightened by risks they can’t control than those they can, even though the risks they can control may be much greater. c)People are afraid of the risk of dying but they are not afraid of death itself. d)The only thing people have to fear is fear itself.

b)Parent’s socioeconomic status. c)Low birth weight. d)Having an intact family. Correct Answer: D 22. Based on the ECLS data, which of the following four factors is positively correlated with children’s test scores? a)Attending Head Start. b)Being adopted. c)Speaking English in the home. d)The child’s parents read to him nearly every day. Correct Answer: C 23. How can we reconcile the finding that there is a positive correlation between having books in the home and a child’s test scores but there is no correlation between the fact that a child’s parents read to him almost every day and the child’s test scores?
a)The analysis obviously did not control for the type of books that are present in the home and this is the problem. b)The analysis obviously did not control for the type of books parents read to their children and this is the problem. c)The fact there is a positive correlation between books in the home and a child’s test scores is picking up the influence of what those children’s parents are, i. e. , well educated. d)We can’t. It’s further evidence that regression analysis is unreliable. Correct Answer: C 24.
Overall, analysis of the ECLS data suggests that what is most important in a child’s development is: a)what parents do and who they are. b)neither what parents do nor who they are but rather something else altogether. c)what parents do but not who they are. d)what parents are but not what they do. Correct Answer: D II. Short Answer/Essay Questions 1. Why do parenting experts tend not to give objective, multi-sided advice to parents? Suggested Answer: Because there are many parenting experts attempting to get the attention of parents.
Those who tend to get more noticed are those who market the “surety” or “certain success” of their methods. 2. Briefly explain the meaning of Sandman’s equation: Risk = hazard + outrage. What does it say about the relationship between the perceived risk and the actual risk of many events? Suggested Answer: Hazard represents the objectively determined risk, i. e. , the probability of a particular undesirable event. Outrage is the degree of emotional response by people to the event’s occurrence. Together, they form the subjective or perceived risk people associate with a particular event.
As such depending on how large the outrage factor is, people may perceive event A as more risky than event B, even though the objective probability of event A’s occurrence is lower. 3. Briefly describe how the scientific analysis of a biologist or a physicist differs, generally speaking, from the scientific approach of an economist. Suggested Answer: A biologist or a physicist can often conduct a controlled experiment in the lab or in the field where one or two variables are allowed to change and the results observed and recorded.
The economist seldom has this luxury in studying economic phenomenon and must rely on other means to “tease out” results from whatever data are available. 4. Explain the difference between correlation and causation. Suggested Answer: If two variables are correlated, they move in a systematic fashion, i. e. , they move together or in opposite directions. Causation implies that a change in one variable causes the value of another variable to change in some predictable way. As such, causation implies correlation, but the reverse is not true, i. e. , correlation does not imply causation.
5. According to the ECLS data discussed by Levitt and Dubner, which is a more important indicator of a child’s success on standardized tests; having lots of books at home or having a parent who reads those books every day to his or her child? What does this suggest about the marginal benefit of reading to one’s child in so far as success on standardized tests is concerned? Suggested Answer: According to the data, so far as academic success goes, having lots of books in a child’s home matters; having a parent who reads every night to his or her child doesn’t matter.
This would suggest that the marginal benefit of reading to one’s child, in so far as performance on tests is concerned, is zero (or close to it). 6. Considering only the measurement of a child’s performance on standardized tests, which is statistically more important: what a parent does for a child or what the parent is? Suggested Answer: According to the ECLS data, what the parent is, measured in terms of socio-economic standing, is more important than what the parent does for the child.
