曼昆经济学原理宏观经济学第六版答案【篇一：曼昆经济学原理(宏观部分答案)】>第二十三章一国收入的衡量复习题 1 ．解释为什么一个经济的收入必定等于其支出? 答：对一个整体经济而言，收入必定等于支出。

因为每一次交易都有两方：买者和卖者。

一个买者的1 美元支出是另一个卖者的1 美元收入。

因此，交易对经济的收入和支出作出了相同的贡献。

由于gdp 既衡量总收入 135 又衡量总支出，因而无论作为总收入来衡量还是作为总支出来衡量，gdp 都相等.2 ．生产一辆经济型轿车或生产一辆豪华型轿车，哪一个对gdp 的贡献更大？为什么? 答：生产一辆豪华型轿车对gdp 的贡献大。

因为gdp 是在某一既定时期一个国家内生产的所有最终物品与劳务的市场价值。

由于市场价格衡量人们愿意为各种不同物品支付的量，所以市场价格反映了这些物品的市场价值。

由于一辆豪华型轿车的市场价格高于一辆经济型轿车的市场价格，所以一辆豪华型轿车的市场价值高于一辆经济型轿车的市场价值，因而生产一辆豪华型轿车对gdp 的贡献更大.3 ．农民以2 美元的价格把小麦卖给面包师。

面包师用小麦制成面包，以3 美元的价格出售。

这些交易对 gdp 的贡献是多少呢? 答：对gdp 的贡献是3 美元。

gdp 只包括最终物品的价值，因为中间物品的价值已经包括在最终物品的价格中了.4 ．许多年以前，peggy 为了收集唱片而花了500 美元。

今天她在旧货销售中把她收集的物品卖了100 美元.这种销售如何影响现期gdp? 答：现期gdp 只包括现期生产的物品与劳务，不包括涉及过去生产的东西的交易。

因而这种销售不影响现期gdp.5 ．列出gdp 的四个组成部分。

各举一个例子.答：gdp 等于消费(c)+投资(i)+政府购买(g)+净出口(nx) 消费是家庭用于物品与劳务的支出，如汤姆一家人在麦当劳吃午餐.投资是资本设备、存货、新住房和建筑物的购买，如通用汽车公司建立一个汽车厂.政府购买包括地方政府、州政府和联邦政府用于物品与劳务的支出，如海军购买了一艘潜艇.净出口等于外国人购买国内生产的物品(出口)减国内购买的外国物品(进口)。

W hat are the components of gross domestic product (GDP)?RESPONSE:ANSWER: The components of GDP are: (1) consumption spending by households on goods and services, with the exception of purchases of new housing; (2)Investment spending on capital equipment, inventories, and structures,including household purchases of new housing; (3) government purchasesor spending on goods and services by the local, provincial, and federal levelsgovernments; and (4) net exports which is spending on domesticallyproduced goods and services by foreigners (exports) minus spending onforeign goods and services by domestic resident (imports).POINTS: -- / 12. D ifferentiate between gross domestic product (GDP) and gross national product (GNP).RESPONSE:ANSWER: GDP is the value of all final goods and services produced within a country ina given year; while GNP is the total income earned by a nation’s permanentresidents or nationals (that is, Canadians). GNP differs from GDP byincluding income that citizens of the nation (Canada) earned aboard, andexcluding income that foreigners earn in the particular country (E.g. inCanada).POINTS: -- / 13. D ifferentiate between real GDP and nominal GDP.RESPONSE:ANSWER: Nominal GDP is the value of all final goods and services produced within a country in a year and valued at current prices; and real GDP is the GDPvalued at constant base year prices.

The three major items included in the CPI are shelter,transportation and food.POINTS: -- / 12. H ow is the CPI computed?RESPONSE:ANSWER: First the basket of goods and services must be determined and also the relative importance of the various items to be included in the basket. Then the prices ofthe various items in the basket are determined. The cost of the basket is thendetermined using the data on prices and quantity. The base year is chosen, andthe index for the base year is computed using the quantities in the basket andthe base year prices. The index is calculated by taking the price of the basket inthe each year and dividing this by the price of the basket in the base year. Thisratio is then multiplied by 100.POINTS: -- / 13. D ifferentiate between the nominal rate of interest and the real rate of interest.RESPONSE:ANSWER: The nominal interest rate is the interest rate as usually reported without a correction for the effects of inflation.

The inflation rate for 1996 would be:POINTS: -- / 15. W hat are the problems associated with using the consumer price index to measure the costof living?RESPONSE:ANSWER: The problems are: (1) Prices do not change proportionately. Consumers respond by buying less of the goods whose prices have risen by large amountsand by buying more of the goods whose price have risen by less, or even fallen.The index is computed using a fixed basket of items, so theses changes inquantity would not be reflected in the basket. This is referred to as thesubstitution bias. (2) The CPI is developed using a fixed basket of goods andservices, when new products are introduced during the time period that aparticular fixed basket is being used, these new products will not be included incalculation of the index. (3) The CPI does not measure quality changes. If thequality of a good deteriorates from one year to the next, the value of the dollarfalls, even if the price of the good stays the same. Likewise, if the quality of thegood increases from one year to the next, the value of a dollar also rises.Statistics Canada will try to adjust the price of the good to account for thequality change, but it is very difficult to measure quality.POINTS: -- / 1CHAPTER 25: PRODUCTION AND GROWTHTrue/FalseIndicate whether the statement is true or false.1.

Quick Quizzes:1. Gross domestic product measures two things at once: (1) the total income of everyone in theeconomy and (2) the total expenditure on the economy’s output of final goods and services.It can measure both of these things at once because all expenditure in the economy ends up assomeone’s income.2. The production of a pound of caviar contributes more to GDP than the production of a pound ofhamburger because the contribution to GDP is measured by market value and the price of apound of caviar is much higher than the price of a pound of hamburger.3. The four components of expenditure are: (1) consumption; (2) investment; (3) governmentpurchases; and (4) net exports. The largest component is consumption, which accounts formore than 70 percent of total expenditure.4. Real GDP is the production of goods and services valued at constant prices. Nominal GDP isthe production of goods and services valued at current prices. Real GDP is a better measure ofeconomic well-being because changes in real GDP reflect changes in the amount of outputbeing produced. Thus, a rise in real GDP means people have produced more goods andservices, but a rise in nominal GDP could occur either because of increased production orbecause of higher prices.5. Although GDP is not a perfect measure of well-being, policymakers should care about itbecause a larger GDP means that a nation can afford better healthcare, better educationalsystems, and more of the material necessities of life.Questions for Review:1. An economy's income must equal its expenditure, because every transaction has a buyer and aseller. Thus, expenditure by buyers must equal income by sellers.2. The production of a luxury car contributes more to GDP than the production of an economy carbecause the luxury car has a higher market value.3. The contribution to GDP is $3, the market value of the bread, which is the final good that issold.4. The sale of used records does not affect GDP at all because it involves no current production.5. The four components of GDP are consumption, such as the purchase of a DVD; investment,such as the purchase of a computer by a business; government purchases, such as an order formilitary aircraft; and net exports, such as the sale of American wheat to Russia. (Many otherexamples are possible.)6. Economists use real GDP rather than nominal GDP to gauge economic well-being because realGDP is not affected by changes in prices, so it reflects only changes in the amounts beingproduced. You cannot determine if a rise in nominal GDP has been caused by increasedproduction or higher prices.7.405The percentage change in nominal GDP is (600 – 200)/200 x 100% = 200%. The percentagechange in real GDP is (400 – 200)/200 x 100% = 100%. The percentage change in the deflator is (150 – 100)/100 x 100% = 50%.8. It is desirable for a country to have a large GDP because people could enjoy more goods andservices. But GDP is not the only important measure of well-being. For example, laws thatrestrict pollution cause GDP to be lower. If laws against pollution were eliminated, GDP wouldbe higher but the pollution might make us worse off. Or, for example, an earthquake wouldraise GDP, as expenditures on cleanup, repair, and rebuilding increase. But an earthquake is anundesirable event that lowers our welfare.Problems and Applications1. a. Consumption increases because a refrigerator is a good purchased by a household.b. Investment increases because a house is an investment good.c. Consumption increases because a car is a good purchased by a household, but investmentdecreases because the car in Ford’s inventory had been counted as an investment gooduntil it was sold.d. Consumption increases because pizza is a good purchased by a household.e. Government purchases increase because the government spent money to provide a goodto the public.f. Consumption increases because the bottle is a good purchased by a household, but netexports decrease because the bottle was imported.g. Investment increases because new structures and equipment were built.2. With transfer payments, nothing is produced, so there is no contribution to GDP.3. If GDP included goods that are resold, it would be counting output of that particular year, plussales of goods produced in a previous year. It would double-count goods that were sold morethan once and would count goods in GDP for several years if they were produced in one yearand resold in another.4. a.

Calculating the percentage change in nominal GDP:Percentage change in nominal GDP in 2011 = [($400 – $200)/$200] ⨯ 100% = 100%.Percentage change in nominal GDP in 2012 = [($800 – $400)/$400] ⨯ 100% = 100%.Calculating the percentage change in real GDP:Percentage change in real GDP in 2011 = [($400 – $200)/$200] ⨯ 100% = 100%.Percentage change in real GDP in 2012 = [($400 – $400)/$400] ⨯ 100% = 0%.Calculating the percentage change in GDP deflator:Percentage change in the GDP deflator in 2011 = [(100 – 100)/100] ⨯ 100% = 0%.Percentage change in the GDP deflator in 2012 = [(200 – 100)/100] ⨯ 100% = 100%.Prices did not change from 2010 to 2011. Thus, the percentage change in the GDP deflator is zero. Likewise, output levels did not change from 2011 to 2012. This means that thepercentage change in real GDP is zero.c. Economic well-being rose more in 2010 than in 2011, since real GDP rose in 2011 but not in2012. In 2011, real GDP rose but prices did not. In 2012, real GDP did not rise but prices did.5. a.

To calculate the growth rate of real GDP, we could simply calculate the percentage changein the quantity of bars. To calculate the inflation rate, we could measure the percentage change in the price of bars.6.a. The growth rate of nominal GDP = 100% ⨯ [($14,256/$9,353)0.10– 1] = 4.3%b. The growth rate of the deflator = 100% ⨯ [(109.886.8)0.10– 1] = 2.4%c. Real GDP in 1999 (in 2005 dollars) is $9,353/(86.8/100) = $10,775.35.d. Real GDP in 2009 (in 2005 dollars) is $14,256/(109.8/100) = $12,983.61.e. The growth rate of real GDP = 100% ⨯ [($12,983.61/$10,775.35)0.10– 1] = 1.9%f. The growth rate of nominal GDP is higher than the growth rate of real GDP because ofinflation.7. Many answers are possible.8. a. GDP is the market value of the final good sold, $180.b. Value added for the farmer: $100.Value added for the miller: $150 – $100 = $50.Value added for the baker: $180 – $150 = $30.c. Together, the value added for the three producers is $100 + $50 + $30 = $180. This is thevalue of GDP.9. In countries like India, people produce and consume a fair amount of food at home that is notincluded in GDP. So GDP per person in India and the United States will differ by more than their comparative economic well-being.10. a. The increased labor-force participation of women has increased GDP in the United States,because it means more people are working and production has increased.b. If our measure of well-being included time spent working in the home and taking leisure, itwould not rise as much as GDP, because the rise in women's labor-force participation has reduced time spent working in the home and taking leisure.c. Other aspects of well-being that are associated with the rise in women's increasedlabor-force participation include increased self-esteem and prestige for women in theworkforce, especially at managerial levels, but decreased quality time spent with children, whose parents have less time to spend with them. Such aspects would be quite difficult to measure.11. a. GDP equals the dollar amount Barry collects, which is $400.b. NNP = GDP – depreciation = $400 – $50 = $350.c. National income = NNP = $350.d. Personal income = national income – retained earnings – indirect business taxes = $350 –$100 – $30 = $220.e. Disposable personal income = personal income – personal income tax = $220 – $70 =$150.。

第8篇宏观经济学的数据第23章一国收入的衡量23.1 复习笔记1．经济的收入与支出在一国的宏观经济中，收入必定等于支出。

这是因为，在每一次交易中，卖者的收入必定等于买者的支出。

国内生产总值（GDP）衡量经济中的总收入或总产量。

由于收入等于支出，可以把经济中赚到的收入（工资、租金和利润）加总起来衡量，也可以用经济中生产的物品和劳务的支出衡量，也就是说，收入等于支出等于GDP。

2．国内生产总值的衡量国内生产总值（GDP）指在某一既定时期一个国家内生产的所有最终物品与劳务的市场价值。

（1）GDP是一个市场价值的概念。

各种最终产品的价值都是用货币加以衡量的。

产品市场价值就是用这些最终产品的单位价格乘以产量获得的。

（2）GDP测度的是最终产品的价值，中间产品价值不计入GDP，否则会造成重复计算。

（3）GDP是指一定时期内（往往为一年）所生产而不是所卖掉的最终产品价值。

（4）GDP是计算期内（如2013年）生产的最终产品价值，因而是流量而不是存量。

流量是一定时期内发生的变量，存量是一定时点上存在的变量。

（5）GDP是一国范围内生产的最终产品的市场价值，从而是一个地域概念，而与此相联系的国民生产总值（GNP）则是一个国民概念，乃指某国国民所拥有的全部生产要素所生产的最终产品的市场价值。

两者的关系是：GNP＝GDP＋［本国生产要素在其他国家获得的收入（投资利润、劳务收入）－外国居民从本国获得的收入］。

稀缺性指在给定的时间内，相对于人的需求而言，经济资源的供给总是不足的，也就是资源的有用性与有限性。

人类消费各种物品的欲望是无限的，满足这种欲望的物品，有的可以不付出任何代价而随意取得，称之为自由物品，如阳光和空气；但绝大多数物品是不能自由取用的，因为世界上的资源（包括物质资源和人力资源）是有限的，这种有限的、为获取它必须付出某种代价的物品，称为“经济物品”。

正因为稀缺性的客观存在，地球上就存在着资源的有限性和人类的欲望与需求的无限性之间的矛盾。

经济学的一个重要研究任务就是：“研究人们如何进行抉择，以便使用稀缺的或有限的生产性资源（土地、劳动、资本品如机器、技术知识）来生产各种商品，并把它们分配给不同的社会成员进行消费。

”也就是从经济学角度来研究使用有限的资源来生产什么、如何生产和为谁生产的问题。

2．经济学（economics）答：经济学是研究如何将稀缺的资源有效地配置给相互竞争的用途，以使人类的欲望得到最大限度满足的科学。

时下经常见诸国内报刊文献的“现代西方经济学”一词，大多也都在这个意义上使用。

一、概念题1．衰退（recession ）答：衰退指收入减少与失业增加较为缓和的经济时期。

一般的衡量标准是国民生产总值连续两个季度下降。

一个完整的经济周期包括繁荣、衰退、萧条、复苏四个阶段。

在繁荣阶段，经济活动全面扩张，不断达到新的高峰。

在衰退阶段，经济在短时间保持均衡后出现紧缩的趋势。

在萧条阶段，经济出现急剧的收缩和下降，很快从活动量的最高点下降到最低点。

在复苏阶段，经济从最低点恢复并逐渐上升到先前的活动量高度，进入繁荣。

2．萧条（depression ）答：萧条是真实GDP 严重减少的时期，指商业周期的紧缩阶段。

经济处于萧条阶段时，经济活动远低于正常水平，企业和消费者的严重悲观情绪持续很长的一个时期，它紧接着在达到一个高峰之后，以周期的低谷而告终。

其特点是：生产急剧缩减，资本投资减少，信用规模收缩，价格持续下滑，失业增多，就业水平降低，企业家与消费者的情绪悲观。

在美国历史上曾发生过两次严重的萧条，一次发生在1873～1879年，一次发生在1929～1933年。

政府采取经济政策干预经济的目的在于缩短或消除这种经济萧条。

3．总需求与总供给模型（model of aggregate demand and aggregate supply ） 答：总需求与总供给模型指将总需求与总供给结合在一起来分析国民收入与价格水平的决定及其变动的国民收入决定模型。

一、概念题1．流动性偏好理论〔theory of liquidity preference〕答：流动性偏好理论是解释实际货币余额的供给与需求如何决定利率的理论。

流动性偏好是人们为应付日常开支、意外支出和进行投机活动而愿意持有现金的一种心理偏好。

该理论由英国著名经济学家约翰·梅纳德·凯恩斯〔J·M·Keynes〕于1936年在《就业、利息和货币通论》中提出。

它根源于交易动机、预防动机和投机动机。

交易动机是为了日常交易而产生的持有货币的愿望,预防动机是为了应付紧急情况而产生的持有货币的愿望。

满足交易动机和预防动机的货币需求数量取决于国民收入水平的高低,并且是收入的增函数。

投机性动机是人们根据对市场利率变化的预测,持有货币以便从中获利的动机。

投机动机的货币需求与现实利率呈负相关。

该理论假设中央银行选择了一个固定的货币供给,在此模型中,价格水平P也是固定的,所以实际货币余额供给固定。

实际货币余额需求取决于利率——持有货币的机会成本。

当利率很高时,因为机会成本太高,人们只会持有较少的货币。

反之,当利率很低时,因为机会成本较低,人们会持有较多的货币。

根据流动性偏好理论,利率会调整到使实际货币余额供给与需求相等的水平。

2．财政政策〔fiscal policy〕答：财政政策指政府变动税收和支出以便影响总需求进而影响就业和国民收入的政策。
