Differentiating Demand Changes and Quantity Demanded

The video tutorial covers the concepts of demand, supply, and equilibrium, focusing on the differences between a change in demand and a change in the quantity demanded, as well as a change in supply and a change in the quantity supplied. It explains how shifts in demand and supply curves are caused by various factors, while movements along these curves are due to price changes. The tutorial concludes with a brief mention of elasticity as the next topic.

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

• A change in demand always leads to a lower price, while a change in the quantity demanded always leads to a higher price.

• A change in demand is related to supply, while a change in the quantity demanded is not.

• A change in demand is caused by a change in price, while a change in the quantity demanded is caused by shifters like income and population.

• A change in demand refers to a shift in the demand curve, while a change in the quantity demanded refers to a movement along a fixed demand curve.

What causes a shift in the demand curve?

• Shifters like income, population, and prices of substitutes

• A change in price

• A change in supply

• A change in technology

What happens to the demand curve when there is an increase in demand?

• It remains unchanged

• It becomes steeper

• It shifts to the right or up

• It shifts to the left or down

What causes a movement along a fixed demand curve?

• A change in price

• A change in population

• A change in income

• A change in technology

What happens to the quantity demanded when supply increases?

• It remains the same

• It increases

• It fluctuates

• It decreases

What is the main difference between a change in supply and a change in the quantity supplied?

• A change in supply is related to demand, while a change in the quantity supplied is not.

• A change in supply always leads to a higher price, while a change in the quantity supplied always leads to a lower price.

• A change in supply is caused by a change in price, while a change in the quantity supplied is caused by shifters like technology and input prices.

• A change in supply refers to a shift in the supply curve, while a change in the quantity supplied refers to a movement along a fixed supply curve.

What causes a shift in the supply curve?

• A change in population

• A change in price

• A change in demand

• Shifters like technology and input prices

What happens to the supply curve when there is an increase in supply?

• It remains unchanged

• It becomes steeper

• It shifts to the right or down

• It shifts to the left or up

What causes a movement along a fixed supply curve?

• A change in input prices

• A change in technology

• A change in demand

• A change in costs

What happens to the quantity supplied when demand increases?

• It increases

• It fluctuates

• It decreases

• It remains the same
