Answer: c. Rent ceilings reduce the quantity and quality of available housing.
Explanation:
Economists are generally known to refuse to agree on most things due to the different schools of economic thought.
One thing they generally agree on however, is that rent ceilings reduce the quantity and quality of available housing.
The reason being that when a rent ceiling is imposed, some landlords will not see the need to improve their housing with the hope of charging higher rent rates which will lead to a reduction in housing quality.
Some landlords will not go into the rental business at all because they might doubt that the rent ceiling will provide them with enough rental income to offset the costs of constructing a building for rent.
