本期导言:
 
下面是本年度香港中学经济科高考第一卷的第三部分(共三部分)的其中一条试题(共3条),考理论与应用。张五常教授借花敬佛,在这里试试中国同学的本领。一个星期后公布答案)
 
 
7、The Hong Kong government has imposed a strict and severe no-smoking law, prohibiting smoking in most public areas.  Milton Friedman said that each and every individual should have the freedom to harm himself, including committing suicide; however, in doing so he may inflict damage on others and create a social cost problem.  One who smokes cigarettes enjoys smoking, but may inflict damage on the health of others nearby.
 

(a) How would you assess the social gains and costs of our new no-smoking law?  Can anyone be certain that the social gains are greater than the social costs?

 

(b) What is the relevance of the Coase Theorem here?  In what sense is this theorem not operative in the no-smoking case?

 

(c) Emissions from automobile engines are said to inflict far more damage on health than smoke from cigarettes.  Why does the Hong Kong government not impose a no-driving rule?
