a.如果中央银行通过固定市场利率来制定货币政策，描述一这时有可能出现的问题。(首先，考虑价格灵活变动的情况，并且试问当中央银行以固定利率向人们提供他们所需的所有货币的时候，你是否会找到唯一的均衡价格水平。然后，考虑存在价格黏性的情况。)
b.根据公式R-R0=a(P- P0)，其中a为正常数，P0为目标价格水平，如果中央银行在价格上升的时候提高利率，形式会发生变化吗？
c.假设中央银行的政策规则是R-R0=a(P-P0)+u，这里的u代表利率政策中的一种随机扰动。在教材中图14-12显示的超调模型中，描述了在一次未预期的随机因素u下降的情况下，经济是怎样调整到长期水平的，并且解释其中的原因。你可以将u的下降解释为中央银行削减利率，并且因此执行了一次货币扩张行动。请将这一.过程与教材中图14-13所描述的过程进行比较。
Typically central banks， rather than purposefully setting the level of the money supply， set a target level for a short-term interest rate by standing ready to lend or borrow whatever money people wish to hold at that interest rate. (When people need more money for some reason other than a change in the interest rate， the money supply therefore expands， and it contracts when they wish to hold less. In the United States， the“policy” interest rate that the Fed sets is called the federal funds rate， and it is the interest rate at which banks make overnight loans to each other.)
a. Describe the problems that might arise if a central bank sets monetary policy by holding the market interest rate constant. First， consider the flexible-price case， and ask yourself if you can find a unique equilibrium price level when the central bank simply gives people all the money they wish to hold at the pegged interest rate. Then consider the sticky-price case.)
b. Is the situation changed if the central bank raises the interest rate when prices are high， according to a formula such as R- R0=a(P- P0)， where a is a positive constant and Po a target price level？
c. Suppose the central bank's policy rule is R-R0=a(P-P0)+u， where u is a random movement in the policy
interest rate. In the overshooting model shown in Figure 14-12， describe how the economy would adjust to a permanent one-time unexpected fall in the random factor u， and why. You can interpret the fall in u as an interest rate cut by the central bank， and therefore as an expansionary monetary action. Compare your story with the one depicted in Figure14-13.
Living Alone Is Joyful
More and more Americans are living alone. Some live alone because of divorce or the death of a partner. (46) According to a recent U. S. census (人口普查), 25 percent of all households in the U, S. are made up of just one person. This is a dramatic change from the extended families of just a couple of generations ago.
The typical person living alone is neither old nor lonely. (47) The majority of these people have chosen to live alone. They are responding to decreasing social pressure to get married and have a family.
It's now socially acceptable, even fashionable, to live alone. As people get better jobs and become financially independent, it becomes possible for them to maintain a one-person household. (48) However, people who do get married are marrying at a later age and divorcing more often.
The number one reason given by most people for living alone is that they simply enjoy doing what they want when they want to do it. "Living alone is a luxury," says Nina Hagiwara, 338, "Once you do it, you can't ever go back to living with others." David C'Debaca, 46, agrees. (49)
Children think that being grown up means being able to do exactly as they please. (50) The chance to discover whether that freedom is as wonderful as it sounds is a chance more and more Americans are taking.
A．There's more pressure to get married nowadays.
B．The growing number of women with good jobs has done much to increase the number of people living alone.
C．However, even more people are living alone because they have chosen to.
D．It seems that many grown-ups today are realizing that childhood dream.
E．In fact, a quarter of the 23 million single people in the U.S. are under the age of 35.
F．He says, "I like being by myself."

The Only Way Is U p
Think of a modem city and the first image that come to mind is the skyline.It is full of great buildings，pointing like fingers to heaven.It is true that some cities don’t permit buildings to go above a certain height.But these are cities concerned with the past.The first thing any city does
when it wants to tell the world that it has arrived is to build skyscrapers.
When people gather together in cities，they create a demand for land.Since cities are places where money is made，that demand can be met.And the best way to make money out of city land is to put as many people as possible in a space that covers the smallest amount of ground.That means building upwards.
The technology existed to do this as early as the l9thcentury.But the height of buildings was limited by one important factor.They had to be small enough for people on the top floors to climb stairs.People could not be expected to climb a mountain at the end of their journey to work，or home.
Elisha Otis，a US inventor，was the man who brought us the lift—or elevator，as he preferred to call it.However，most of the technology is very old.Lifts work using the same pulley system the Egyptians used to create the Pyramids.What Otis did was attach the system to a steam engine and develop the elevator brake.which stops the lift falling if the cords that hold it up are broken.It was this that did the most to gain public confidence in the new invention.In fact，he spent a number of years exhibiting lifts at fairgrounds，giving people the chance to try them before selling the idea to architects and builders.
A lift would not be a very good theme park attraction now.Going in a lift is such an everyday thing that it would just be borin9.Yet psychologists and others who study human behavior. find lifts fascinatin9.The reason is simple.Scientists have always studied animals in zoos.The nearest they can get to that with humans is in observing them in lifts.
“It breaks all the usual conventions about the bubble of personal space we carry around with us—and you just can’t choose to move away”，says workplace psychologist，Gary Fitzgibbon.Being trapped in this setting can create different types of tensions，he says.Some people are scared of them.Others use them as an opportunity to get close to the boss.Some stand close to the door.Others hide in the corners.Most people try and shrink into the background.But some behave in a way that makes others notice them.There are a few people who just stand in a corner taking notes.
Don’t worry about them.They are probably from a university.
