17.A person has a comparative advantage at producing something if he can produce it at lower cost than anyone else.
Having a comparative advantage is not the same as being the best at something.In fact,someone can be completely unskilled at doing something,yet still have a comparative advantage at doing it!How can that happen?
Let's get some more vocabulary.Someone who is the best at doing something is said to have an absolute advantage.Lance Armstrong (自行车环法七冠王) has an absolute advantage at cycling.For all I know,Lance Armstrong may also be the fastest typist in the world,giving him an absolute advantage at typing,too.Since he's better at typing than you,can't he type more cheaply than you?That is,if someone has an absolute advantage in something,doesn't he automatically have a comparative advantage in it?The answer is no!If Lance takes time out from cycling to do all his own typing,he sacrifices the large income he earns from entertaining fans of the Tour de France (环法自由车赛).If,instead,his secretary does the typing,the secretary gives up an alternative secretarial job-or perhaps a much lower salary as a cyclist.That is,the secretary is the lower-cost typist.The secretary,not Lance Armstrong,has the comparative advantage at typing!The trick to understanding comparative advantage is in the phrase"lower cost."What it costs someone to produce something is the opportunity cost-the value of what is given up.Someone may have an absolute advantage at producing every single thing,but he has a comparative advantage at many fewer things,and probably only one or two things.
