▶ Reading Comprehension ☞ Choose the best answer based on the article. Opportunity Cost: “There Ain’t No Such Thing As A Free Lunch What do you think about this phrase “There ain’t no such thing as a free lunch”? Do you really think there is no free lunch? Or, do you think there is a free lunch? How would you react if your friend treats you to lunch? Would you take it without a second thought? Would you consider it a free lunch because you do not pay? Most would consider it a free lunch and gladly take it. However, in economy, there is no such thing as a free lunch. You have to give up something to get a free lunch. For example, you want to read a book after taking a quick bite during the lunch time. Your friend comes to you and offers you lunch. The lunch seems to be free. Actually, it is not because you have to give up your reading. ”There is no such thing as a free lunch” is often used to demonstrate what “opportunity cost” is. When economists refer to the “opportunity cost” of a resource, they mean the value of the next-highest-valued alternative use of that resource. For example, if you spend time and money going to a movie, you cannot spend that time at home reading a book, and you cannot spend that money on something else. If your next-best alternative to seeing the movie is reading the book, then the opportunity cost of seeing the movie is the money spent plus the pleasure you forgo by not reading the book. As a student, you can find out what your opportunity cost is. For example, you pay $1,000 per year for your tuition. You may think your cost is $1,000 per year. Actually, you pay more than $1,000. You cannot work while you attend your school. If you worked, you could have made $10,000 per year. In this case, your opportunity cost of going to school is $11,000, the money you pay for your tuition plus the money you forgo by not working. 18. What are economists referring to when they talk about the opportunity cost of a resource? ① They are talking about the value of the next highest valued alternative use of a particular resource we use. ② They are refering to the money we spend on an activity or resource. ③ They are refering to the cost of a particular resource. Example: Going to the movie costs us $15. ④ They are talking about lunches and how they cannot be free Economy
