| 簡介： | The laws of supply and demand make up a crucial piece of our economic system. They may even sound like something that most people don't have any need for. But consumers encounter them every day, whether they know it or not. Readers will learn that whenever we buy something, see a commercial for the season's hottest new product, or decide that we can't afford that new smartphone, the laws of supply and demand are at work. Understanding the concept of supply and demand will help readers understand why we spend money, and even help them make better decisions with their spending. |
