Have you ever wanted to buy something, but couldn’t afford to pay for it? Do you sometimes wonder why what you want costs so much money? Think about the latest and greatest smart phone. The company that makes that phone must answer two important questions: How many new phones should we produce? How much should we charge for each new phone that we sell? The answers to these questions can be found in two economic concepts—supply and demand.

Objectives

  • Explain how supply and demand work in a market economy.
  • Describe how scarcity and opportunity cost affect how a market functions.

Imagine that you want to set up your first business, a lemonade stand. For your business, you need to make many decisions, such as how much lemonade to make, and how much to charge for each glass of lemonade.


Which of the following would be your business strategy?

A) Make as much lemonade as possible, I’m a great salesperson.
B) Make a little bit of lemonade, but charge a lot for each glass.
C) Make a lot of lemonade, but sell each glass for a low price.
D) Make a lot of lemonade, and keep the price high.

Ask for student volunteers to explain why they chose their preferred strategy. Point out that each strategy has possible benefits and risks.


As a business owner, you have many options when it comes to making economic decisions. However, only some of those choices may lead to success. If you made too much lemonade and didn’t sell it, you would lose money. If you charged too much for each glass, you might not sell as many glasses. In this experience, you will learn some of the concepts involved in economic decisions.
