Q4
QUESTION:
Referring to the graph, fully explain the consequences of a Maximum Price Control on the market for houses for rent. Include the following: quantity demanded before and after the price control/ quantity supplied before and after the price control/ a problem the price control might create and a possible solution for the problem outlined.
ANSWER:
The consequences of the Maximum Price Control on houses for rent is that the quantity demanded before the price control was 3500 houses and after 4000 houses. The quantity supplied of houses decreases from 3500 houses to 2500 houses. A problem created by the price control is a shortage of 1500 houses. A black market could arise because some customers are willing to pay a higher price that the legally set price of $350. Possible solutions to the shortage could be first-in-first-served, rationing or the government could give producers a subsidy and increase supply.

Q6
QUESTION:
Explain how a government price control measure can reduce the availability of houses for consumers to rent?
ANSWER:
A maximum price is where the government prohibits charging a price higher than a certain level. An effective maximum price control does not allow the market to clear (ie, a shortage is created) and some consumers may miss out. A maximum price control will cause the price of the good to fall and result in less houses available for rent because landlords decrease the quantity supplied of homes due to the decrease in the price.
