一、概念题1．绝对优势（absolute advantage）答：绝对优势指可以用较少量的投入生产物品的一种生产率方面的优势。
绝对优势比较的是生产一种物品所需要的投入量，如果生产者生产一种物品所需要的投入较少，则可以说该生产者在生产该物品上有绝对优势。
绝对优势理论由英国古典经济学家亚当·斯密（Adam Smith）为反对当时的重商主义和保护贸易政策在其1776年的巨著《国富论》中提出，主张以各国生产成本的绝对差异为基础进行国际专业化分工，并通过自由贸易获得利益。
如果一国某种产品的绝对生产成本或价格比其他国家低，就称该国具有这种产品上的绝对优势，因而该国就应完全专业化生产并出口这种产品，同时进口那种它具有绝对劣势的产品。
这种基于绝对优势的国际分工和自由贸易的结果将使贸易各方都可获得贸易利益。
换言之，在斯密看来，贸易应该是一场双赢的“正和博弈”。
这一思想开启了整个国际贸易理论的先河。
2．机会成本（opportunity cost）答：机会成本指将一种资源用于某种特定用途所放弃的使用该项资源在其他用途中所能获得的最大收益。
机会成本的存在需要三个前提条件：①资源是稀缺的；②资源具有多种生产用途；③资源的投向不受限制。
从机会成本的角度来考察生产过程时，厂商需要将生产要素投向收益最大的项目，而避免生产的浪费，达到资源配置的最优。
从经济资源的稀缺性这一前提出发，当一个社会或一个企业用一定的经济资源生产一定数量的一种或者几种产品时，这些经济资源就不能同时被使用在其他的生产用途方面。

一、选择题1. 经济学的研究对象是：A. 物质生产过程B. 社会生产关系C. 市场交换关系D. 资源配置和财富分配答案：D解析：经济学是研究如何有效配置资源以生产商品和劳务，并分配这些产品与劳务的学科，因此研究对象是资源配置和财富分配。
2. 下列哪项不是经济学中的基本假设？A. 理性人假设B. 完美信息假设C. 市场竞争假设D. 通货膨胀假设答案：D解析：理性人假设、完美信息假设和市场竞争假设是经济学中的基本假设，而通货膨胀假设不是。
3. 下列哪项不是市场失灵的原因？A. 公共物品的非排他性B. 垄断的存在C. 外部性的存在D. 消费者偏好多样化答案：D解析：消费者偏好多样化是市场有效运行的条件之一，而不是市场失灵的原因。
市场失灵的原因通常包括公共物品的非排他性、垄断的存在和外部性的存在。
4. 下列哪项不是经济周期的四个阶段？A. 复苏B. 高涨C. 调整D. 繁荣答案：C解析：经济周期的四个阶段通常包括复苏、高涨、衰退和萧条，调整不是经济周期的阶段。
5. 下列哪项不是宏观调控的目标？A. 稳定物价B. 就业充分C. 经济增长D. 优化资源配置答案：D解析：宏观调控的目标包括稳定物价、就业充分和经济增长，而优化资源配置是宏观调控的手段之一，不是目标。
二、填空题1. 经济学的基本假设是__________、__________和__________。
答案：理性人假设、完美信息假设、市场竞争假设解析：经济学的基本假设包括理性人假设，即经济主体追求自身利益最大化；完美信息假设，即经济主体拥有充分的信息；市场竞争假设，即市场是充分竞争的。
2. 市场失灵的主要原因是__________、__________和__________。
答案：公共物品的非排他性、垄断的存在、外部性的存在解析：市场失灵的主要原因包括公共物品的非排他性，即一旦生产出来，无法阻止他人免费享用；垄断的存在，即市场只有一个或少数几个卖家，导致价格控制；外部性的存在，即生产或消费活动对他人产生了成本或收益，而市场没有反映这些成本或收益。

二、分析讨论1.如何理解西方经济学是一门考察稀缺的资源合理配置的科学。
答：西方经济学认为，人类的欲望和由此引起的对物品和劳务的需要是无限多样的，可是用来满足这些无限需要的手段即用来提供这些物品和劳务的生产资源是稀缺的。
这样，就产生了如何分配使用这些有限的资源来满足无限需要的问题，这就是“选择”，也就是“配置”资源的问题。
人类社会面临的经济问题就是如何把有限的资源合理地和有效率地分配使用于各种途径以满足人类无限多样的需要。
在市场经济中，资源的配置是通过市场价格机制来实现的。
生产什么、生产多少、如何生产、为谁生产，都是由市场价格决定的。
假若人类能无限量地生产出各种物品，或者人类的欲望能够完全得到满足，即在这样一个丰裕的伊甸园里，不存在稀缺物品，所有的物品都是免费的，像沙漠中的沙和海岸边的海水，价格和市场互不相关，那么经济学就无须存在了。
正是由于人类欲望的无限性和生产资源的有限性之间的矛盾才引起了人类的经济活动，西方经济学也就成为一门考察稀缺资源的配置的科学。

经济学原理课后习题及答案经济学原理课后习题及答案经济学原理课是大学经济学专业的基础课程之一，通过学习这门课程，学生可以了解经济学的基本原理和理论，培养经济分析和决策能力。
在课程学习过程中，老师通常会布置一些习题作为课后作业，以检验学生对课程内容的理解和掌握程度。
下面是一些经济学原理课后习题及答案的示例。
1. 供给和需求习题：假设某种商品的市场供给曲线为Qs = 100 + 2P，市场需求曲线为Qd = 200 - P，求市场均衡价格和数量。
答案：市场均衡价格和数量可以通过供给和需求曲线的交点来确定。
将供给和需求方程联立，得到100 + 2P = 200 - P，解得P = 33.33。
将P代入供给或需求方程中，得到Qs = 100 + 2 * 33.33 = 166.67，Qd = 200 - 33.33 = 166.67。
因此，市场均衡价格为33.33，市场均衡数量为166.67。
2. 边际效用习题：某人消费3个苹果的总效用为20，消费4个苹果的总效用为25，求第4个苹果的边际效用。
答案：边际效用是指消费一单位商品所带来的额外效用。
根据题意，当消费3个苹果时，总效用为20；当消费4个苹果时，总效用为25。
因此，第4个苹果带来的额外效用为25 - 20 = 5。
3. 机会成本习题：某人有两个选择：A和B。
选择A可以获得100元，但放弃选择B可以获得200元。
求选择A的机会成本。
答案：机会成本是指选择某个方案所放弃的最高价值的替代方案。
在这个例子中，选择A可以获得100元，但放弃选择B可以获得200元。
因此，选择A的机会成本为200元。
4. 生产可能性边界习题：某国家只生产两种商品：A和B。
生产一个单位的A需要消耗2个单位的劳动力，生产一个单位的B需要消耗3个单位的劳动力。
该国家有100个单位的劳动力。
画出该国家的生产可能性边界。
答案：生产可能性边界是指在资源有限的情况下，一个国家或企业所能生产的各种商品组合。
