In Nigeria, the government can reduce the cost of accommodation by fixing the rent

A.

At the prevailing rate

B.

At the equilibrium price

C.

Above the equilibrium price

D.

Below the equilibrium price

Correct answer is D

The government can reduce the cost of accommodation by fixing the rent at a maximum price. Maximum prices occur when a government sets a legal limit on the price of a good or service – with the aim of reducing prices below the market equilibrium price.

 

Governments try to control the rate charged for rent by keeping the cost of renting below a certain level. However, 

 

setting the price below equilibrium maximum will cause a shortage – demand will be greater than supply.

B.

It provides low degree of freedom

C.

D.

Consumers are sovereign

Correct answer is A

Price mechanism refers to the system where the forces of demand and supply determine the prices of commodities. This means that, prices are left in the fate of market forces negating the concept of consumer sovereignty.

 

Consumers are forced to purchase those goods which producers want. Thus, the producer is sovereign, not the consumer.
