Chapter 3: Problem 28

How does a price ceiling set below the equilibrium level affect quantity demanded and quantity supplied?

Short Answer

Expert verified

A price ceiling set below the equilibrium level leads to an increase in the quantity demanded and a decrease in the quantity supplied, thereby creating a shortage in the market. This occurs because the lower price increases demand, while simultaneously reducing suppliers' incentives to produce the good or service. The resulting shortage can lead to limited availability for consumers and should be considered when implementing such policies.

Step by step solution

Define Price Ceiling

A price ceiling is a government-imposed limit on the maximum price that can be charged for a good or service. When a price ceiling is set below the equilibrium price, it results in a shortage because the quantity demanded exceeds the quantity supplied.

Draw the Demand and Supply Curve

To visualize the effects of a price ceiling, we begin by drawing a demand and supply curve. The demand curve shows the relationship between the quantity demanded and the price of a good, while the supply curve shows the relationship between the quantity supplied and the price. The equilibrium price occurs at the intersection of the demand and supply curve, where the quantity demanded equals the quantity supplied.

Introduce the Price Ceiling

Now we need to introduce the price ceiling, which is set below the equilibrium price. You can represent this by drawing a horizontal line, intersecting the demand and supply curves below the equilibrium point. The intersection of this price ceiling line with the demand and supply curve indicates the quantity demanded and the quantity supplied at this price.

Analyze the Quantity Demanded and Quantity Supplied

The price ceiling forces the market price to be lower than the equilibrium price, causing the quantity demanded to increase (since as price decreases, demand usually increases) and the quantity supplied to decrease (since as price decreases, producers are less willing to supply the good). At the price ceiling, the quantity demanded exceeds the quantity supplied, which creates a shortage.

Interpret the Results

A price ceiling set below the equilibrium level leads to an increase in the quantity demanded and a decrease in the quantity supplied, creating a shortage in the market. In this situation, suppliers may not have enough incentive to produce the good or service, while consumers may face difficulties finding the good or service due to limited availability. This consequence should be considered when policymakers decide to impose price ceilings in the market.
