Homework 1 (due 10/3, 2006) Hints (1) #3. $9,600 The opportunity cost of going to school is $9,600 of goods and services. The opportunity cost of going to school this summer is the highest-valued activity that you will give up so that you can go to summer school. In going to summer school, you will forgo all the goods and services that you could have bought with the income from your summer job ($6,000) plus the expenditure on tuition ($2,000), textbooks ($200), and living expenses ($1,400). 很多人都忘了计算＄3600元，而只计算了$6000。这样的算法是不正确的。 因为机会成本的概念是想要让大家在以前计算成本的想法之外， 还要【额外】的考虑背後隐含（implicit）的成本。 #6. The opportunity cost of seeing a free movie is the highest-valued activity that you forgo by spending the time (say 3 hours) at the movie house. If you usually buy popcorn and a soft drink, then the cost of these are also part of the opportunity cost of seeing a free movie. The opportunity cost of seeing Lord of the Rings is the same as for a free movie plus the $4 that you could have spent on other goods and services minus the cost of the soft drink. So seeing which movie has the higher opportunity cost depends on whether the value of the soft drink is bigger than or less than $4. 上面是给大家的参考答案。但是，这一题的题目并不是非常的完整。 让我举一个简单的例子，假设，今天你抽中了一张伍佰演唱会的入场券，所以决定去看 伍佰的演唱会。然而，同时间，张惠妹也办了演唱会，你去了伍佰的演唱会之後，你就无 法去张惠妹的演唱会，而且，张惠妹的演唱会是你的次佳选择（即，若不去伍佰的演唱会 ，在众多当天的同时间可以进行的活动当中，你会去张惠妹的演唱会。）张惠妹的演唱会 门票是一千块钱，然而，你心中愿意付的张惠妹的票价是一千五百块，请问去参加伍佰演 唱会的机会成本是多少？ 答案是五百块。 这是因为，次佳的选择（张惠妹的演唱会） ，对你而言的『价值』是五百块。 所以，想想看，魔戒这一题的题目少给了哪些假设？？在你自己的假设之下，重新计算机 会成本。 (2.) #1. a. omit b. (i) 1991; (ii) 1998; (iii) 1995, 1996, 1999, 2000; (iv) 1992, 1994, 1997, 1998, 2001; (v) 2000; (vi) 1992 c. omit #2. a. omit. b.

Please make sure that you really know how to use those words. 似乎有些组别无法清楚的区分总体和个体的区别，请再看一下课本的定义。 请注明资料的来源，以後作业若是没有注明资料来源，一律当作抄袭处理。 (4) Omit. Please make sure that you really know how to use those words. (5) Omit. Please make sure that you really know how to use those words. (6) Omit. Please make sure that you really know how to use those words. Fallacy of composition: (Parkin, page 13) The fallacy of composition is the (false) statement that what is true of the parts is true of the whole or that what is true of the whole is true of the parts. 以Parkin这本书的定义而言，指的是一个论证在个别成立与否和推广到全部群体的 这论证是否成立的问题(或是相反的情形)。而非只一个事件对个体与总体有利或无利。 当然，不同的书籍对这样的词汇的定义会不同。 NOTICE： （1.）如果你作业是用打的话，请用12的字，请体谅助教眼睛不好。 （2.）作业可以不用抄题，不过题号要写清楚。 （3）作业记得在第一页写上组别，组员学号。尽量都用A4的纸写。 If you have any questions about this homework, please feel free to mail me.
