Final answer:
When the government imposes a price ceiling below the unregulated equilibrium price in a perfectly competitive market, the quantity demanded increases, the quantity supplied decreases, and a shortage of units occurs.
Step-by-step explanation:
A price ceiling is a legal maximum price set by the government in a market. When the government imposes a price ceiling below the equilibrium price in a perfectly competitive market, several things happen:
- The quantity demanded increases: When the price is lower, more consumers are willing and able to purchase the product, thus increasing the quantity demanded.
- The quantity supplied decreases: Since the price ceiling prevents the price from rising to the equilibrium level, producers are discouraged from supplying as much of the product, leading to a decrease in the quantity supplied.
- A shortage occurs: The quantity demanded exceeds the quantity supplied, resulting in a shortage in the market.
Therefore, in summary, when the government intervenes and imposes a price ceiling below the unregulated equilibrium price in a perfectly competitive market, the quantity demanded increases, the quantity supplied decreases, and a shortage of units occurs.
