Basic Economics
However useful economics may be for understanding many issues, it is not as emotionally satisfying as more personal and melodramatic depictions of these issues often found in the media and in politics. Dry empirical questions are seldom as exciting as political crusades or ringing moral pronouncements. But empirical questions are questions that must be asked, if we are truly interested in the well-being of others, rather than in excitement or a sense of moral superiority for ourselves. Perhaps the most important distinction is between what sounds good and what works. The former may be sufficient for purposes of politics or moral preening, but not for the economic advancement of people in general or the poor in particular. For those who are willing to stop and think, basic economics provides some tools for evaluating policies and proposals in terms of their logical implications and empirical consequences.
If this book has contributed to that end, then it has succeeded in its mission.

The pages in parentheses are where answers to these questions can be found in the print edition.
PART I: PRICES AND MARKETS
1. Can there be a growing scarcity without a growing shortage—or a growing shortage without a growing scarcity? Explain with examples. (pages 38, 47–48)
2. Can a decision be economic, if there is no money involved? Why or why not? (pages 6–7)
3. Can there be surplus food in a society where people are hungry? Explain why or why not. (pages 54–55)
4. When a housing shortage suddenly disappears, within a time period too short for any new housing to have been built, and yet people no longer have any trouble finding a vacant home or apartment, what has probably happened? What will probably happen in the longer run? Explain. (page 39)
5. Which of the following are—or are not—affected by price controls that limit how high the product’s price can go: (a) the quantity supplied, (b) the quantity demanded, (c) the quality of the product, (d) a black market for the product, (e) hoarding of the product, (f) the supply of auxiliary services that usually go with the product, or (g) efficiency in the allocation of resources? Explain in each case. (a: pages 41–44; b: pages 39–41; c: pages 49–50, 51–53; d: pages 50–51, 53; e: pages 48–49; f: page 42; g: pages 52–53, 64–65)
6. Building ordinary housing and building luxury housing involves using many of the same resources, such as bricks, pipes, and construction labor. How does the allocation of these resources between ordinary housing and luxury housing tend to change after rent control laws are passed? (pages 43, 47)
7. Are prices usually higher or lower in low–income neighborhoods? Why? Include among prices the interest rate on money borrowed and the cost of getting paychecks cashed. (pages 66–68)
8. When a government institution or program produces counterproductive results, is that necessarily a sign of irrationality or incompetence on the part of those who run that particular institution or program? Explain with examples. (pages 70–72)
9. We all consider some things more important than others. Why then can there be a problem when some official government policy establishes “national priorities”? (pages 77–78)
10. We tend to think of costs as the money we pay for things. But does that mean that there would be no costs in a primitive society that did not yet use money or in a modern cooperative community, where people collectively produce the goods and services they use and do not charge each other for them? (pages 22, 28)
11. How does rent control affect the average number of persons per apartment and the average amount of time that the same persons stay in the same apartment? (pages 39–41)
12. Back in the days of the Soviet Union, the government owned and operated most of the enterprises in the economy. Most prices were set by central planners, rather than by supply and demand, and the success or failure of Soviet enterprises was judged primarily by how well they met the numerical targets for production, which were set by the central planners. Specify five ways in which this arrangement produced different economic end results from those in market economies. (pages 17, 22–23, 27, 71, 73–74)
13. How can the price of baseball bats be affected by the demand for paper or the price of catchers’ mitts be affected by the demand for cheese? (page 20)

1. Why would a big corporation pay millions of dollars in severance money to an executive who has been a complete failure, who has turned corporate profits into corporate losses? (page 145)
2. Why has Toyota manufactured cars with only enough inventory of parts to last a few hours? Why did Soviet industries have nearly enough inventory to last for a year? (page 136)
3. Why do American manufacturers of computers or television sets tend to have them transported by others while Chinese manufacturers tend to transport them themselves? (page 135)
4. How did the movement of population from rural to urban America affect the economics of retail selling in the early twentieth century? How did the later movement of population from urban to suburban America in the second half of the twentieth century affect the economics of department stores and grocery stores? Explain with examples. (pages 92–93, 96–97)
5. Why is it that General Motors can make millions of automobiles, without making a single tire to go on them, while Soviet enterprises not only tended to make all their own components, but sometimes even made the bricks for the buildings in which they operated? (pages 130, 134)
6. How did diseconomies of scale in agriculture affect the way tractor drivers plowed fields in the Soviet Union? What if agricultural enterprises had been privately owned and the tractor drivers were plowing their own fields? Would the work have been done differently and would the farm be likely to be as large? Explain why or why not. (pages 123–124)
7. When an economic project such as building a railroad or creating an airline requires far more money than any given individual can or will invest, what are some of the things that can facilitate or impede the pooling of the money of millions of people to finance the project? (pages 140–142)
8. Advertising, even when it is successful, is often considered to be a benefit only to those who advertise, but of no benefit to consumers, who have to pay the cost of the advertisements in the higher price of the products they buy. Evaluate this view from an economic perspective. (pages 120–121, 574–577)
9. “Inertia is common to people under both capitalism and socialism, but the market exacts a price for inertia." Explain how and why inertia among mail order houses, which were the leading retailers in the United States in the early twentieth century, was affected by the rise of department store chains. (pages 96–98, 182)
10. Why are retired people able to get much lower priced travel rates—on cruise ships, for example—than most other people? Explain the economic reasons. (pages 125–126)
11. Why is the perennial desire to “eliminate the middleman” perennially frustrated? (pages 130–133)

15. Stores in low–income neighborhoods tend to charge higher prices, in order to try to compensate for higher costs and for slower rates of turnover in their inventory. What limits the ability of these stores to completely compensate for these higher costs, so a
s to make the same rates of profits as stores in higher–income neighborhoods? (pages 118–119)

3. Some studies have attempted to determine how employment has changed in the wake of a minimum wage increase by surveying individual firms before and after the increase to find out how their employment has changed, and then adding up the results. What is the problem with this procedure? (page 225)
4. What has been the effect of multinational corporations in China on wages and working conditions there? (pages 245–247)

7. Although maximum wage laws existed long before minimum wage laws, only the latter are common today. However, in those special cases where there have been maximum wage laws—as under wage and price controls during World War II, for example—what effects would such laws have on discrimination against minorities and women? How would maximum wage laws and minimum wage laws differ in their effects on discrimination? (pages 214, 231–233)
8. Does inequality of income tend to be greater or less in the long run than in the short run? Why do many statistics about “the rich” and “the poor” include people who are neither rich nor poor in reality? (pages 199–200)
9. When drivers of municipal transit buses are unionized and paid more than they would be paid in a free, competitive market, what effect does that tend to have on the size of the buses and the waiting time between buses? (page 215)
10. How can differences in the quality of transportation systems or in the level of corruption in different countries affect the value of labor? (page 197)
11. Why would a South African manufacturer expand production by opening a plant in Poland, when there were large numbers of workers available in South Africa, where the unemployment rate was 26 percent, and where the average output per hour of South African workers was higher than the average output per hour of Polish workers? (pages 195–196, 227–228)
12. Why is the productivity of an individual not the same as the efficiency or merit of that individual? Give examples comparing workers in Third World countries with workers in more prosperous countries, and comparing different baseball players in different kinds of situations. (pages 196–197)
13. It has often been said that, over time, a higher percentage of the nation’s total income goes to high income people. In what sense is this true and in what sense is it not true? (pages 203–207)
14. Why are wages lower, and working conditions worse, in Third World countries? What are the likely consequences of various possible ways of trying to improve either or both? (pages 244–247)
15. What are the implications of the fact that most people today reach their peak earnings years at later ages than in generations past—and that these peak earnings are now usually a larger number of times greater than the earnings of beginners than in times past? What further implications does this have for the changing differences in male and female earnings? (pages 208–209)

1. Does it make economic sense for a ninety-year-old man, with no heirs, to plant trees that will take 20 years to grow to maturity and bear fruit? (page 292)
2. Businesses raise money by issuing both stocks and bonds but individuals usually raise money by borrowing—the equivalent of issuing bonds. In some circumstances, however, individuals acquire resources by the equivalent of issuing stocks. What are those circumstances? Give specific examples and reasons. (pages 313–315)
3. Why may the statistics on the known reserves of a natural resource provide a misleading picture of how much of that resource there is in the ground? (pages 294–301)

7. Why would a bus company owned or controlled by the government charge fares too low to replace existing buses as they wear out? What if the executives of a privately owned and privately controlled bus company decided to divert part of the money they received from bus fares toward paying themselves higher salaries, instead of setting aside enough money to replace buses as they wear out? What would happen to the value of the stock in their company and how would the stockholders be likely to react? (pages 337–338)
8. Many poor countries have confiscated businesses or land owned by wealthy foreign companies. Why has this seldom made the poor country more prosperous? (pages 340–341)

12. Why do manufacturers in some countries keep an inventory of many months’ supply of the materials needed in production, while manufacturers in some other countries do not keep an inventory of such materials sufficient to last all day? What are the implications for the allocation of scarce resources which have alternative uses? (pages 135–137, 289–291)

PART V: THE NATIONAL ECONOMY
1. How does the consumer price index tend to exaggerate the rate of inflation and how does that affect our attempts to measure real income? (pages 353–355)
2. Does the presence or absence of property rights make any difference to people who own no property? For example, are tenants affected economically by whether the community in which they rent apartments or houses allows unbridled property rights or reduces those property rights through zoning laws, open space laws, height restrictions on buildings, or rent control laws? (pages 400–404)
3. How does the level of honesty or corruption in a country affect the effectiveness of its economy? How do economic policies affect the level of honesty and corruption? (pages 394–396)

8. In medieval times, the British economy lagged behind that of some economies in continental Europe but, in later centuries, Britain had the leading economy in Europe and led the world into the industrial age. How and why did foreigners play a major role in developing the British economy? (page 398)
9. Those who favor increases in tax rates are often disappointed that the additional revenue turns out to be less than they expected. Conversely, those who fear that cuts in tax rates will substantially reduce the government’s revenues have often been surprised to find the government’s revenues rising. Explain both phenomena. (pages 426–428)
10. Even if detailed statistics are available, why is it difficult to compare the national output at the beginning of the twentieth century with the national output at the beginning of the twenty-first century, and say by what percentage it has increased? Why is it hard even to say how much prices for particular goods have increased from one century to another? (pages 352–354)
