LEARNING OBJECTIVES: By the end of this chapter, students should understand: the link between buyers’ willingness to pay for a good and the demand curve. how to define and measure consumer surplus. the link between sellers’ costs of producing a good and the supply curve. how to define and measure producer surplus. that the equilibrium of supply and demand maximizes total surplus in a market. CONTEXT AND PURPOSE: Chapter 7 is the first chapter in a three-chapter sequence on welfare economics and market efficiency. Chapter 7 employs the supply and demand model to develop consumer surplus and producer surplus as a measure of welfare and market efficiency.

微观经济学课后习题答案

第一章答案 二、选择题 1.B 2.D 3.C 4.C 5.D 6.B 7.C 8.A 三、简答题 1.微观经济学的假设前提是什么? 答:微观经济学有四个假设前提:资源稀缺性、市场出清、完全理性、完全信息 2.微观经济学有什么特点? 答:微观经济学的特点:(1)用数学语言描述经济现象与规律;(2)以价格理论为核心;(3)以均衡为目标;(4)理论与现实紧密结合 3.微观经济学要解决什么样的问题? 答:微观经济学要解决的三大基本问题是:生产什么,生产多少;如何生产;为谁生产。 4.微观经济学的研究对象是什么? 答:微观经济学的研究对象是个体经济单位。具体从三个层面展开的: 第一个层面:分析单个消费者、单个要素供给者和单个生产者的经济行为。 第二个层面:研究单个市场的价格决定(局部均衡)。 第三个层面:研究所有市场的价格同时决定。 四、论述题 1.请介绍微观经济学的新发展。 答:微观经济学的新发展体现在理论上新发展、方法上新发展和微观经济学发展的新趋势三个方面。 理论上的新发展主要体现在:(1)提出了新消费理论,包括显示性偏好理论、风险条件下的选择理论、消费也是家庭生产的理论;(2)提出了现代企业理论,包括企业的性质、最大化模型与委托——代理问题、内部组织效率与非最大化厂商理论;(3)博弈论改写了微观经济学;(4)信息经济学成为微观经济分析的主流。 方法上的新发展主要体现在三个方面:一是计量经济学的崛起,二是统计学在经济学中的大规模运用,三是博弈论引入到经济学。 微观经济学发展的新趋势包括:(1)假定条件多样化,(2)研究领域的非经济化,(3)学科交叉的边缘化。 2.微观经济学与宏观经济学有何区别? 答:微观经济学与宏观经济学的区别体现在:(1)研究对象不同。微观经济学的研究对象是单个经济单位,二宏观经济学的研究对象则是整个经济,研究整个经济的运行方式与规律,从总量上分析经济问题。(2)解决的问题不同。微观经济学要解决的是资源配置问题,而研究社会范围内的资源利用问题,以实现社会福利的最大化。(3)假设前提不同。微观经济学的基本假设是市场出清、完全理性、完全信息和资源稀缺,而宏观经济学则假定市场机制是不完善的,政府有能力调节经济。(4)研究方法不同。微观经济学的研究方法是个量分析,即研究经济变量的单项数值如何决定,而观经济学的研究方法则是总量分析,即对能够反映整个经济运行情况的经济变量的决定、变动及其相互关系进行分析。(5)中

Ch 1 Ten Principles of economic ?Scarcity: the limited nature of society’s resources ?Economics: the study of how society manages its scarce resources, e.g. ?There are 10 principle of economic which are needed to be remember throughout. ?People face trade-off 1. Individual(time,money) and society(efficiency vs equality). ?Cost of something is what your give up to get it.\ 1. The opportunity cost of any item is whatever must be given up to obtain it. ?Rational people thinking at margin(effect of one additional item) 1. This principle assume that everyone is rational people(made their decision base on their interests) this was addressed on Adam Smith's Wealth of Nation. ?People respond to incentives(诱惑物) 1. This statement reveals that human psychology is a important feature in economic study. ?Trade can make everyone better-off 1.Ex: trade of agricultural product and technology between Japan and America, it will break the law of PPF. It involved absolute advantages(low input) and comparative advantage(low opportunity cost win) ?Markets are usually a good way to organize economy activity. 1.Markets can balance the price. ?Government can sometime improve market outcome. ? A country's standard of living depends on its ability to produce goods and services. ?Price rise when government print too much money.

微观经济学课后习题答案<高鸿业版> 第1章课后习题详解 1.回想你看到过或接触过的西方经济学著作。它们各自属于本章所说的三种类别中的哪一种? 答:第一类,企事业的经营管理方法和经验。如行情研究、存货管理、产品质量控制、车间生产流程布局等内容。著作有《现代企业财务管理》等。 第二类,对一个经济部门或经济问题的集中研究成果。如资源经济学、商业经济学、农业经济学、石油经济学,对税收、财政和通货膨胀等问题的论述。著作有《资源经济学》、《农业经济学》。 第三类,经济理论的研究和考察。如微观经济学、数理经济学、福利经济学、经济思想史等。著作有《宏观经济学》、《微观经济学》、《经济思想史》等。 2.为什么我国学员学习西方经济学的目的不同于西方? 答:由于西方经济学具有双重性质,它既是资本主义的意识形态,由是资本主义市场经济的经验总结,这就决定了我国学员学习它所应持有的态度:在整个的理论体系上或整体倾向上对它持否定的态度,而在具体的内容上应该看到它的有用之处,是否真正有用还需要考虑到国情的差别,应结合我国的国情加以借鉴吸收,做到“弃其糟粕、取其精华、洋为中用”。 (1)我国学习下岗经济学的主要目的在于从中得到对我国有用的知识,即“学以致用”。对西方经济学而言,“为艺术而艺术”的学习目标是不适用的。因为,如果不是为了“实用”而学习,那么还不如去从事其它的活动。“经济学”这一名词的英文来源是希腊文的名词“家庭管理”。由此也可以看出西方经济学的“致用”的性质。 (2)既然学习西方经济学的目的是为了“致用”,那么就必须注意到它涉及对西方“致用”的两个特点:其一,它宣扬西方国家的意识形态,以便巩固西方社会的共识或凝聚力,即增加西方学者所说的“社会无形资本”;其二,它总结西方市场运行的经验,以便为改善其运行提供对策。西方经济学之所以能够存在于西方,其原因即在于此;这就是说:它存在于西方的原因正是由于他对西方国家有用。 (3)在以上两个特点中,第一个特点显然对我国不但没有用处,反而会引起有害的作用。因为,西方实行的是资本主义,而我国则为社会主义,而二者在原则上是对立的。把资本主义的意识形态施加于社会主义制度只能造成和激化后者的上层建筑与其经济基础之间的矛盾,导致思想混乱、社会行为失控,甚至走向自我毁灭的道路。类似的事例已经在世界上出现。 (4)以上述第二个特点而论,虽然西方国家实行的是资本主义市场经济,而我国则为社会主义市场经济,但是,二者在市场经济这一点上却有相当多的共同之处。因此,对西方市场经济运行的经验总结和总结的方法有许多内涵是值得而且必须加以借鉴的。以此而论,学习西方经济学又是对我国有利的。当然,在借鉴时,决不能生搬硬套,必须注意到国情的差别,在西方社会中行之有效的办法未必能在我国奏效。 (5)趋利避害,上述两个特点可以决定我们对西方经济学所应持有的态度,即:在整体内涵上,否定它的资本主义的意识形态,因为,在整体内涵上,它维护资本主义制度;另一方面,在具体内容上,它总结出的经验和总结的方法却存在着大量的值得借鉴之处。 总结上述五点,我国学员学习西方经济学的态度应该是要做到“洋为中用”,即:能充分利用西方经济学中的一切有利于我国的知识,而与此同时,又能避免它在意识形态上所带来的不良后果。 3.英国的著名西方经济学家罗宾逊说:“宣传成分是这一学科(指西方经济学——引

英文版微观经济学复习提纲Chapter 5. Economic efficiency, government price setting and taxes

5 Economic Efficiency, Government Price Setting, and Taxes Chapter Summary Although rent controls no longer in Australia, many governments around the world, such as Malaysia and the U.S., have placed ceilings on the maximum rent some landlords can charge for some apartments and houses. Governments also impose taxes in some markets. To understand the economic impact of government in markets it is necessary to understand consumer surplus and producer surplus. Consumer surplus is the dollar benefit consumers receive from buying goods and services at market prices less than the maximum prices they would be willing to pay. Producer surplus is the dollar benefit producers receive from selling goods and services at prices greater than the minimum prices they would be willing to accept. In a competitive market with no externalities the equilibrium price for a good or service occurs where the marginal cost of the last unit produced and sold is equal to the marginal benefit consumers receive from the last unit bought. At this same level of output, economic surplus, the sum of consumer and producer surplus, is maximized. Although price controls on rent no longer exist in Australia, there are many other examples of the government setting prices, such as the minimum wage in labour markets (a “floor price”). Compared to the competitive equilibrium, price ceilings and price floors reduce economic efficiency. A tax on the sale of a good or service also reduces economic efficiency. The burden of a tax (or tax incidence) is the degree to which consumers or producers actually pay the tax. The incidence of a tax depends on how responsive producers and consumers are to the price change caused by the tax. Learning Objectives When you finish this chapter you should be able to: 1Understand the concepts of consumer surplus and producer surplus. Consumer surplus is the benefit consumers receive from paying a price lower than the maximum price they would be willing to pay. Producer surplus is the benefit a firm receives from selling a good or a service at a price higher than the minimum the firm would be willing to accept. Economic surplus is the sum of consumer surplus plus producer surplus. 2Understand the concept of economic efficiency, and use a graph to illustrate how economic efficiency is reduced when a market is not in competitive equilibrium. An economically efficient outcome occurs when a competitive market equilibrium is reached. Maximum economic efficiency results when the marginal benefit received by consumers from the last unit bought equals the marginal
