If the government removes the
binding price floor from the market than the price of the good will
fall to the equilibrium level. As the price floor was binding, the
price at equilibrium must have been lower than the price floor. If
the price floor is removed than the price will come down to the
price set by the demand and supply forces in the market.
Therefore the correct option should be that the price
paid by buyers will decrease, and the quantity sold in the market
will increase considering the increase in demand due to fall in
price.
Under rent control, bribery is a
mechanism to bring the total price of an apartment (including the
bribe) closer to the equilibrium price. The rent control will
increase the demand for rented homes and reduce the supply of homes
in the market. This will increase the competitions among the buyers
to get a home. However many tenants will remain homeless. To avoid
this condition they are forced to pay a bribe for getting a rented
home.
