Answer:
Surplus of 21 units would occur.
Explanation:
There are either of the two steps taken by the government:
(i) Price ceiling: This is a situation in which government sets the price below the equilibrium price level in the market.
(ii) Price floor: This is a situation in which government sets the price above the equilibrium price level in the market.
The equilibrium price occurs at a point where the quantity demanded is equal to the quantity supplied. Therefore, in our case, the equilibrium price is $45 where quantity demanded and quantity supplied are equal to 62 units.
Hence, the price set by the government is price floor.
At price floor of $50,
Quantity supplied = 73 units
Quantity demanded = 52 units
So, there is a surplus of (73 units - 52 units) = 21 units.
