所谓货币流通速度V是指实际GNP与实际货币持有量的比率，V=Y/(M/P)。请利用等式(14-4)推导货币流通速度的表达式，并解释货币流通速度是如何随R和Y的变化而变动的。(提示：产出变化对v的影响取决于相对于实际产出的货币总需求弹性，经济学家认为该弹性小于1。)货币流通速度与汇率之间存在什么联系？
The velocity of money，V，is defined as the ratio of real GNP to real money holdings，V=Y/(M/P)in this chapter's notation．Use equation(14-4)to derive an expression for velocity and explain how velocity varies with changes in R and in Y．(Hint：The effect of output changes on V depends on the elasticity of aggregate money demand with respect to real output，which economists believe to be less than unity．)What is the relationship between velocity and the exchange rate？

In 1870, horses and mules were the prime source of power on U.S. farms. One horse or mule was required to support four human beings—a ratio that remained almost constant for many decades. At that time, had a national commission been asked to forecast the horse and mule population for 1970, its answer probably would have depended on whether its consultants were of an economic turn of mind. Had they been "economists", they would have recognized that the power of steam had already been harnessed to industry and to land and ocean transport. They would have recognized further that would be only a matter of time before steam would be the prime source of power on the farm. It would have been difficult for them to avoid the conclusion that the horse and mule population would decline rapidly.

A．Older technologies die away.
B．The quality of life is improved.
C．Overall productivity increases.
D．More raw materials become necessary.

Those who criticize economic growth argue that we must slow down. They believe that society is approaching certain limits on growth. These include the fixed supply of natural resources, the possible negative effects of industry on the natural environment, and the continuing increase in the world's population. As society reaches these limits, economic growth can no longer continue, and the quality of life will decrease.
People who want more economic growth, on the other hand, argue that even at the present growth rate there are still many poor people in the world. These proponents of economic growth believe that only more growth can create the capital needed to improve the quality of life in the world. Furthermore, they argue that only continued growth can provide the financial resources required to protect our natural surroundings from industrialization.
This debate over the desirability of continued economic growth is of vital importance to business and industry. If those who argue against economic growth are correct, the problems they mention cannot be ignored. To find a solution, economists and the business community must pay attention to these problems and continue discussing them with one another.
1.We may infer from the context that "proponents “ (Paragraph 3)most probably means .
[A] arguments in support of something
[B] disagreement
[C] people who argue for something
[D] people who argue against something

Some economists believe that taxes have an important effect on labor supply. They argue that higher taxes cause people to want to work less and that lower taxes cause them to want to work more. Consider how this effect alters the macroeconomic analysis of tax changes.
a．If this view is correct, how does a tax cut affect the natural rate of output？
b．How does a tax cut affect the aggregate demand curve？ The long-run aggregate supply curve？ The short-run aggregate supply curve？
c．What is the short-run impact of a tax cut on output and the price level？ How does your answer differ from the case without the labor-supply effect？
d．What is the long-run impact of a tax cut on output and the price level？ How does your answer differ from the case without the labor-supply effect？

Some have argued that such rights are merely luxuries that wealthy societies bestow, but Olson turns that argument around and asserts that such rights are essential to creating wealth. "Incomes are low in most of the countries of the world, in short, because the people in those countries do not have secure individual rights," he says.
Certain simple economic activities, such as food gathering and making handicrafts, rely mostly on individual labor; property is not necessary. But more advanced activities, such as the mass production of goods, require machines and factories and offices. This production is often called capital-intensive, but it is really property-intensive, Olson observes.
"No one would normally engage in capital-intensive production if he or she did not have rights that kept the valuable capital from being taken by bandits, whether roving or stationary," he argues. "There is no private property without government--individuals may have possessions, the way a dog possesses a bone, but there is private property only if the society protects and defends a private right to that possession against other private parties and against the government as well."
Would-be entrepreneurs, no matter how small, also need a government and court system that will make sure people honor their contracts. In fact, the banking systems relied on by developed nations are based on just such an enforceable contract system. "We would not deposit our money in banks ... if we could not rely on the bank having to honor its contract with us, and the bank would not be able to make the profits it needs to stay in business if it could not enforce its loan contracts with borrowers," Olson writes.
Other economists have argued that the poor economies of Third World and communist countries are the result of governments setting both prices find the quantities of goods produced rather than letting a free market determine them. Olson agrees that there is some merit to this point of view, but he argues that government intervention is not enough to explain the poverty of these countries. Rather, the real problem is lack of individual rights that give people incentive to generate wealth. "If a society has clear and secure individual rights, there are strong incentives (刺激，动力) to produce, invest, and engage in mutually advantageous trade., and therefore at least some economic advance," Olson concludes.
Which of the following is true about Olson？
A．He was a fiction writer.
B．He edited the book Power and Prosperity.
C．He taught economics at the University of Maryland.
D．He was against the ownership of private property.

Ironically, the first evidence for this idea appeared in the United States. Not long ago, with the country entering a recessing and Japan at its prebubble peak, the U.S. workforce was derided as poorly educated and one of the primary cause of the poor U.S. economic performance. Japan was, and remains, the global leader in automotiveassembly productivity. Yet the research revealed that the U.S. factories of Honda, Nissan, and Toyota achieved about 95 percent of the productivity of their Japanese counterparts—a result of the training that U.S. workers received on the job.
More recently, while examining housing construction, the researchers discovered that illiterate, non-English-speaking Mexican workers in Houston, Texas, consistently met best-practice labor productivity standards despite the complexity of the building industry’s work.
What is the real relationship between education and economic development？ We have begun to suspect that continuing economic growth promotes the development of education even when governments don’t force it. After all, that’s how education got started. When our ancestors were hunters and gatherers 10,000 years ago, they didn’t have time to wonder much about anything besides finding food. Only when humanity began to get its food in a more productive way was there time for other things.
As education improved, humanity’s productivity potential increased as well. When the competitive environment pushed our ancestors to achieve that potential, they could in turn afford more education. This increasingly high level of education is probably a necessary, but not a sufficient, condition for the complex political systems required by advanced economic performance. Thus poor countries might not be able to escape their poverty traps without political changes that may be possible only with broader formal education. A lack of formal education, however, doesn’t constrain the ability of the developing world’s workforce to substantially improve productivity for the foreseeable future. On the contrary, constraints on improving productivity explain why education isn’t developing more quickly there than it is.
