In four or more sentences, explain if rent control is a price floor or price ceiling. Then explain one advantage and one disadvantage of rent control.

Rent control is a mechanism by which the price of renting is kept within certain boundaries, such that it doesn't rise beyond a given level, nor grows at a rate higher than a specified rate. It's therefore a price ceiling. It can't be a price floor because any owner may decide to charge a fee as low as one may not be able to imagine. While there's no restrictions as to how low a landlord can go in terms of charging renters, the concept of price floor can't be considered here.
