To determine which price control results in a shortage of 300,000 apartments, we need to analyze the supply and demand data at different price points. A shortage occurs when the quantity demanded exceeds the quantity supplied.
Looking at the table:
-
At $1,000:
- Quantity Demanded: 600,000
- Quantity Supplied: 300,000
- Shortage = 600,000 - 300,000 = 300,000
-
At $1,500:
- Quantity Demanded: 500,000
- Quantity Supplied: 500,000
- Shortage = 500,000 - 500,000 = 0 (market equilibrium)
-
At $2,000:
- Quantity Demanded: 400,000
- Quantity Supplied: 700,000
- Shortage = 400,000 - 700,000 = -300,000 (surplus)
-
At $2,500:
- Quantity Demanded: 300,000
- Quantity Supplied: 900,000
- Shortage = 300,000 - 900,000 = -600,000 (surplus)
Since a shortage of 300,000 apartments occurs specifically at the price of $1,000, it indicates that the government has implemented a price ceiling at this level to keep prices low.
Thus, the correct answer is:
a price ceiling of $1,000.
