INTRODUCTION

As consumers, you and your friends buy goods and services every day. Producers of these goods and services are interested in consumer behavior because they want to produce products that will be popular with consumers, deliver the products to markets, and sell the products for a profit. To understand consumer behavior, you need to understand demand.

TASK

In this lesson you will learn about demand and factors that cause demand for a good or service to change. You will learn to recognize factors that influence your behavior as a consumer.

Demand is the relationship between various prices and the quantities consumers are willing and able to buy during some time period, holding all other things constant. Demand is not a single price and quantity demanded from the schedule. Demand is the entire schedule.

Use the Bubble Soda example and determine how demand would change and why for each of the examples.

CONCLUSION

In this lesson you have reviewed the law of demand and how price changes affect the amount of a good or service consumers are willing and able to buy. You also learned about the non-price determinants of demand. Non-price determinants result in a change in demand. A change in demand means that the amount consumers are willing and able to buy changes at each and every price. Non-price determinants are sometimes called demand shifters. Test your knowledge by completing the attached true/false quiz.
