LEARNING OBJECTIVES
After you have read this section, you should be able to answer the following questions:
What gives money value?
What are the functions of money?
Take a look at some currency—a dollar bill, for example. It is nothing more than a piece of paper with writing on it. A very pretty piece of paper, perhaps, with fancy writing and some pictures, but it is still just a piece of paper. Yet people voluntarily give up valuable goods or services in exchange for pieces of paper. This is the mystery of money.
The question motivating this chapter—why do people want money?—is a deep one. That may seem a surprising claim because obviously we all like having money. But questions that seem trivial sometimes provide insights into how the world works. If we can understand why people want these intrinsically worthless pieces of paper, then we can understand why money is valuable. And to understand why people want these pieces of paper, we need to know what people want to do with their money.
