In some cases, the government can intervene in the market when the equilibrium price is too high or low. For example, a price ceiling is a legal maximum price that can be charged in a particular market. Do some research on your own.
Is a price ceiling set above or below the market price?
Give an example of a price ceiling and discuss some disadvantages and advantages of this type of government intervention.

1- A price ceiling is a price set by the government, above which the product cannot be sold. Therefore, it's a maximum but this maximum is below the market price.
2- A certain level of rent is an example of a price ceiling. The government set this ceiling in order to help those who rent apartments pay a lower price than the equilibrium price, that's the advantage of a price ceiling (it helps consumers pay a lower price).

This would lead to a creation of a black market activity: people paying more rent but under the table.
