大学宏观经济学等经济学题目讲解

　　宏观经济学课程通常涉及国民收入、通货膨胀、经济增长等课程主题。对于作业或者考试题目，可能不知需要学生了解相关的经济学概念，还需要能根据这些基础概念，去分析某一种或者某一类的经济现象。下面我们提供一些经济学题目，需要练习的同学赶紧收藏吧!

　　一、选择题

　　1. In the IS-MP model, a tax cut:

　　a. Increases consumption.

　　b. Increases investment.

　　c. Increases output.

　　d. Increases the real interest rate.

　　e. (b) and (d).

　　f. (a), (c), and (d).

　　g. All of the above.

　　2. The effect of expansionary fiscal policy on the AD curve drawn accounting for the

　　zero lower bound is to:

　　a. Shift the downward-sloping portion of the curve to the right and not shift the

　　upward-sloping portion.

　　b. Shift the upward-sloping portion of the curve to the right and not shift the

　　downward-sloping portion.

　　c. Shift the two portions of the curve to the right by equal amounts.

　　d. Shift both portions of the curve to the right, but shift the downward-sloping

　　portion more than the upward-sloping portion.

　　e. Shift both portions of the curve to the right, but shift the upward-sloping portion

　　more than the downward-sloping portion.

　　3. If the Federal Reserve is targeting the money supply and decides to tighten monetary

　　policy, this would manifest itself as:

　　a. An upward shift of the LM curve.

　　b. A downward shift of the LM curve.

　　c. A leftward shift of the IS curve.

　　d. A rightward shift of the IS curve.

　　e. Such a decision cannot be captured in the IS-LM model; we must use IS-MP

　　instead.

　　二、判断题

　　1. The real exchange rate falls (that is, depreciates) as we move down along a

　　conventional downward-sloping AD curve.

　　2. The key advantage of natural experiments if we are trying to determine the effect of

　　one variable, x, and another variable, y, is that they focus on cases where the only factor

　　affecting y that changed was x.

　　3. In the short run, an increase in consumer confidence raises the real interest rate,

　　Consump.

　　三、解答题

　　Answer all parts of the question. Be sure to explain your answers and to draw diagrams

　　where they are appropriate. Your explanation and analysis determine your grade.

　　1. Consider an economy in long-run equilibrium: output is equal to its natural rate (Y-),

　　and as a result, inflation is steady. Assume that the central bank is following an interest

　　rate rule, and that nominal interest rates are above zero.

　　In this situation, suppose there is an adverse inflation shock. That is, some

　　outside shock (such as a spike in oil prices) causes inflation to change suddenly from its

　　initial level, π0, to a higher level π1. Assume that the shock does not change normal

　　Output，Y-

　　a. What is the short-run effect of this development on output, the real interest rate,

　　consumption, and investment?

　　b. What is the short-run effect on the real exchange rate and net exports?

　　c. How do output and inflation change over time after the initial shock? What will

　　they be in the long run?

　　四、宏观经济学题目知识点讲解

　　宏观经济学的一些重点知识，常常会以不同形式出现在各种经济学题目中。以下是两个关键的知识点总结。

　　1.什么是GDP?如何计算GDP?

　　GDP(国内生产总值)是一个国家或地区在一定时期内生产的所有最终商品和服务的市场价值的总和。GDP的计算可以通过三种方法：产出法、收入法和支出法。产出法是根据各个产业的产出值来计算GDP;收入法是根据各个经济主体的收入来计算GDP;支出法是根据最终消费支出、投资、政府支出和净出口来计算GDP。

　　2.什么是货币政策?货币政策的目标和工具是什么?

　　货币政策是指中央银行通过调整货币供应量和利率等手段来影响经济运行的政策。货币政策的目标通常包括稳定物价水平、促进就业和经济增长。货币政策的工具包括利率调控、公开市场操作和存款准备金率等。中央银行通过调整这些工具来实现货币政策的目标。
