The Law of Demand

Understanding Supply and Demand

BELL RINGER:  On a piece of paper, answer the following under "Bell Ringer" and then put them in the 3rd Block Bin:

1. Refresher: What is the difference between scarcity and shortage?
2. Think about your fictitious business and explain what product or service is supplied by you, and who demands that product or services.
3. What does the Latin phrase "ceteris paribus" mean?
4. Looking at the Supply & Demand graph (right), which of the lines is Supply and which is Demand?

Supply and Demand
As you would probably imagine, Supply and Demand are concepts that are the cornerstone of Economic Theory.  The entire concept of Economics is the study of how and why people choose to buy the things they do.  So much, in fact, that out of the 61 Tennessee Economics Standards, 6 of them specifically involve Supply and Demand.

• E.11 Define supply and demand, and provide relevant examples. (E)
• E.12 Describe the role of buyers and sellers in determining the equilibrium price. (E)
• E.13 Describe how prices of products as well as interest rate and wage rates send signals to buyers and sellers of products, loanable funds, and labor. (E)
• E.14 Explain that consumers ultimately determine what is produced in a market economy (consumer sovereignty). (C, E)
• E.17 Identify factors that cause changes in market supply and demand. (E)
• E.18 Demonstrate how changes in supply and demand influence equilibrium price and quantity in the product, resource, and financial markets. (E)

In addition to supply and demand, we will be working on the following standards:

• E.2 Explain how consumers and producers confront the condition of scarcity, by making choices that involve opportunity costs and tradeoffs. (E)
• E.4 Describe how people respond predictably to positive and negative incentives. (C, E)
• E.5 Explain that voluntary exchange occurs when all participating parties expect to gain. (E)
• E.23 Compare and contrast the following forms of business organization: sole proprietorship, partnership, and corporation. (E)
