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?
Section B
Directions: In this section, you will hear 3 short passages. At the end of each passage, you will hear some questions. Both the passage and the questions will be spoken only once. After you hear a question, you must choose the best answer from the four choices marked A, B, C and D.
听力原文: Do you know how to advertise for a bank? If you ask people about the functions of a bank, they would probably say that the bank is where you can deposit money and cash a check. But it's much more than these. And we have to tell people this in our advertisement.
There are several things to think about for a bank advertisement. (26)The first problem is to decide who should be our audience. Should our advertisement be aimed at adults with full employment only? Or should it also appeal to students, housewives, retired workers, or even children? It is a good idea to address the largest possible audience. If we introduce the name of our bank to children they will never forget it.
The next question is how to attract people of different social groups to our bank. The usual tip is to offer free gifts, for example, portable radios or T-shirts for the young and gold pens for business executives. That always works. But what do we give to our best customers? That's another question. What about leather diaries, for example?
Banks are very competitive. We have to think of something new to offer our customers. That's the third problem. Ours is one of the first banks to have drive-in service and to open on Saturdays, but now many banks do. Most banks also offer a variety of checking and saving accounts and a full range of investment plans to suit the needs of their customers, as well as the 24-hour ATM banking which makes it much faster and easier for customers to withdraw cash or do other things. (27)To attract more customers to our bank, it is essential that we have something that no other bank offers.
