其次，货币作为流通手段，可以在市场上作为交换媒介，方便商品和服务的买卖交易。
最后，货币作为储藏手段，人们可以将其储存起来，以备将来使用。
2. 请解释通货膨胀对经济的影响。
通货膨胀对经济的影响有以下几方面：首先，通货膨胀会降低货币的购买力，导致物价上涨，减少人们的消费能力和生活水平。
其次，通货膨胀会扭曲资源配置，由于价格上涨，生产成本增加，导致企业投资意愿下降，影响经济的正常运行。
此外，通货膨胀还会引发收入分配的不平等，对固定收入者和储蓄者造成损失，而对资产持有者带来收益。
最后，通货膨胀会削弱国家货币的国际竞争力，影响国际贸易和债务偿还。

2. 解释什么是货币乘数效应，并说明其对经济的影响。
答案：货币乘数效应是指银行系统通过存款创造货币的能力。
当银行收到存款时，它们可以贷款出去一部分，而贷款又会变成新的存款，从而产生更多的贷款和存款。
这个过程可以不断重复，使得初始存款的总效应放大，影响经济中的货币供应量。
三、计算题（每题15分，共30分）1. 假设一个封闭经济体的总支出方程为Y = C + I + G，其中Y是GDP，C是消费，I是投资，G是政府支出。
已知C = 100 + 0.8(Y - T)，I = 50，G = 200，T = 50。
请计算均衡GDP。
答案：首先计算消费函数C = 100 + 0.8(Y - 50) = 100 + 0.8Y - 40 = 60 + 0.8Y。
将C、I、G代入总支出方程得到Y = 60 + 0.8Y + 50 + 200。

中国人民大学宏观经济学期末考试试题(含答案)
1）奥肯定律[答案]：奥肯定律的含义是失业率与实际国民生产总值之间存在一种高度负相关关系。
奥肯定律的主要内容是：失业率如果超过充分就业界限（通常以4%的失业率为标准）时，每使失业率降低1%，实际国民生产总值则增加3%。
反之，失业率每增加1%，实际国民生产总值则减少3%。
2）一个农民种植了 1 蒲式耳小麦，并以1 美元的价格卖给磨坊主。
磨坊主把小麦磨成面粉，然后以3 美元的价格卖给面包师。
面包师用面粉制造面包，并以6 美元的价格卖给一个工程师，工程师吃了面包。
每个人的增加值是多少？GDP 是多少？[答案] 每个人的增值等于成品的价值减去每个人支付的原材料的成本。
因此农民的增值S1（1刀）；面粉厂的增值为S2（3-1=2刀）；面包店的增值为S3（6-3=3刀）。
GPD 是总的价值增量，即1+2+3=6刀。
注意：GDP与最终产品（面包）价值相等。
3）把下列交易归入四个支出部分之一：消费、投资、政府购买以及净出口。
A、波音公司向空军出售一架飞机（政府购买）B、波音公司向美国航空公司出售一架飞机（投资）C、波音公司向法国航空公司出售一架飞机（净出口）D、波音飞机向阿密拉•埃尔哈特出售了一架飞机（消费）E、波音公司制造了一架下半年出售的飞机（投资）4）考虑有三种投入的柯布-道格拉斯生产函数。
K 是资本（机器数量）、L 是劳动（工人人数）、H 是人力资本（工人中大学毕业生人数）。
生产函数为：A、推导出劳动的边际产量。
人力资本量的增加如何影响劳动的边际产量？B、推导出人力资本的边际产量的表达式。
人力资本量的增加怎样影响人力资本的边际产量？C、支付给劳动的收入份额是多少？支付给人力资本的收入份额是多少？在这个经济的国民收入核算中。
你认为工人会得到多大的总收入份额？D、一个不熟练工人赚到劳动的边际产量，而一个熟练工人赚到劳动的边际产量加人力资本的边际产量。
用你对（A）和（B）的[答案]，找出熟练工人与不熟练工人的比率。

If an individual or company is not confident that claims over property or over the income from property can be protected, or that contracts can be enforced, there will be little incentive for individuals to save, invest, or start new businesses. Likewise, there will be little incentive for foreigners to invest in the real or financial assets of the country. The distortion of incentives will reduce efficiency in resource allocation and will reduce saving and investment which in turn will reduce the standard of living.57．Suppose that you are a broker and people tell you the following about themselves. What sort of bond would you recommend to each? Defend your choices.a. "I am in a high federal income tax bracket and I don't want to take very much risk."A municipal bond, because generally they have low credit risk and are not subject to federal income tax.b. "I want a high return and I am willing to take a lot of risk to get it."A junk bond. Because of their high risk, they have a high return.c. "I want a decent return and I have enough deductions that I don't value tax breaks highly."A corporate bond that isn't a junk bond.

Increases in the money supply cause the aggregate demand curve to shift right. Output growth puts downward pressure on the price level, but money supply growth contributes to rising prices.62．Why do economists think that the wealth effect and exchange-rate effect are not very important factors in explaining why aggregate demand slopes downward, at least in the United States?The wealth effect is not very important because it operates through changes in the real value of money, and money is only a small fraction of household wealth. So it is unlikely that changes in the price level will lead to large changes in consumption spending through this channel. The exchange-rate effect is not very important in the United States because trade with other countries represents a relatively small fraction of U.S. GDP.63．Describe the process in the money market by which the interest rate reaches its equilibrium value if it starts above equilibrium.If the interest rate is above equilibrium, there is an excess supply of money. People with more money than they want to hold given the current interest rate deposit the money in banks and buy bonds. The increase in funds to lend out causes the interest rate to fall. As the interest rate falls, the quantity of money demanded increases, which tends to diminish the excess supply of money. 64. Assume the economy is in a recession. Explain how each of the following policies would affect consumption and investment. In each case, indicate any direct effects, any effects resulting from changes in total output, any effects resulting from changes in interest rate, and the overall effect. If there are conflicting effects making the answer ambiguous, say so. a). a reduction in taxes; b) an expansion of the money supply.a) 税收减少增加了储蓄的收益、减少了投资的成本，但税收减少对储蓄和投资的影响要视情况而定。
