Understanding the Law of Demand

This video tutorial explains the law of demand, a fundamental concept in microeconomics. It describes how the quantity demanded of a product changes inversely with its price. The video distinguishes between 'demand' and 'quantity demanded' and introduces the demand schedule, a table showing the relationship between price and quantity demanded. Using an ebook pricing example, the video illustrates how to create a demand schedule and plot a demand curve. The tutorial concludes by emphasizing the difference between changes in demand and changes in quantity demanded.

What does the law of demand state about the relationship between price and quantity demanded?

• Price and quantity demanded are unrelated.

• As price increases, quantity demanded decreases.

• As price decreases, quantity demanded decreases.

• As price increases, quantity demanded increases.

In economic terms, what is the difference between 'demand' and 'quantity demanded'?

• 'Demand' refers to a specific quantity, while 'quantity demanded' refers to the entire relationship.

• 'Demand' is only used in macroeconomics.

• 'Demand' refers to the entire relationship, while 'quantity demanded' refers to a specific quantity.

• Both terms mean the same thing.

What does 'ceteris paribus' mean in the context of demand?

• All demand is constant.

• All other factors are held constant.

• All prices are equal.

• All quantities are equal.

What is a demand schedule?

• A graph showing the relationship between supply and demand.

• A schedule of when products will be available.

• A list of prices for different products.

• A table showing the relationship between price and quantity demanded.

In the ebook example, what happens to the quantity demanded when the price is increased from $2 to $4?

• It increases to 60,000.

• It increases to 80,000.

• It remains the same.

• It decreases to 40,000.

What happens to the quantity demanded if the price of the ebook is set at $10?

• It increases to 60,000.

• It remains at 40,000.

• It increases to 30,000.

• It decreases to 23,000.

What is the purpose of a demand curve?

• To illustrate the relationship between price and quantity demanded as a continuous curve.

• To show the relationship between supply and demand.

• To list all possible prices for a product.

• To predict future market trends.

Why is price typically plotted on the vertical axis in a demand curve?

• Because it is a law of mathematics.

• Because it is more accurate.

• Because it is easier to read.

• Because it is a convention in economics.

What does a shift in the demand curve indicate?

• A change in market equilibrium.

• A change in demand due to factors other than price.

• A change in supply.

• A change in quantity demanded due to price change.

When only the price changes, what happens on the demand curve?

• There is movement along the curve.

• The curve remains unchanged.

• The curve disappears.

• The entire curve shifts.
