Demand Dynamics: Distinguishing Between Quantity Demanded and Demand Shifts

The video tutorial explains the difference between a change in quantity demanded and a change in demand. A change in quantity demanded is a movement along a fixed demand curve due to a price change, while a change in demand is a shift in the demand curve caused by factors like income or preferences. The tutorial uses examples, such as sugary fizzy drinks, to illustrate these concepts. It emphasizes that changes in variables not on the price or quantity axes result in demand curve shifts. The video concludes with suggestions for further learning and practice.

What is the main difference between a change in quantity demanded and a change in demand?

• A change in demand is a movement along the demand curve.

• A change in quantity demanded is due to price changes, while a change in demand is due to other factors.

• A change in quantity demanded is a shift in the demand curve.

• Both are caused by changes in consumer preferences.

What causes a movement along a fixed demand curve?

• A change in the price of the good

In the example of sugary fizzy drinks, what caused the decrease in quantity demanded?

• A change in consumer preferences

• An increase in the price of sugary fizzy drinks

• A viral marketing campaign for a substitute product

• A decrease in consumer income

What happens to the demand curve when there is a change in demand?

• It moves along the curve

• It shifts to the right

• It remains unchanged

• It shifts to the left

Which of the following is NOT a factor that can cause a shift in the demand curve?

• Change in the price of related goods

• Change in consumer income

• Change in the price of the good

• Change in consumer preferences

How does a decrease in demand affect the demand curve?

• It does not affect the curve

• It causes a movement along the curve

• It shifts the curve down and to the left

• It shifts the curve up and to the right

What is tracked on the y-axis of a demand graph?

• Price

• Quantity

• Income

• Preferences

Which of the following would cause a shift in the demand curve?

• A change in consumer income

• A change in the quantity supplied

• A change in the price of the good

• A change in the price of the good's complement

What does a movement along the demand curve indicate?

• A change in the price of the good

• A change in consumer income

• A change in the price of related goods

• A change in consumer preferences

What is the effect of a viral marketing campaign for a substitute product on the demand for sugary fizzy drinks?

• It decreases the demand for sugary fizzy drinks
