Answer: a. benefits Boxlandian consumers by $672 and harms Boxlandian producers by $598.50.
Explanation:
Equilibrium price will be at level where quantity demanded equals quantity supplied.
200 − 2P = -60 + 3P
200+60 = 5P
5P = 260
P = $52
Equilibrium Quantity Demanded = 200 − 2P = 200 - 2 * 52 = 96 units
In a no-trade situation the demand in Boxland is 96 units at a price of $52. If they were to buy at the world price of $45, they would benefit;
= (96 * 52) - (96 * 45)
= 4,992 - 4,320
= $672
Producers however would produce the following at a price of $45;
Q S = -60 + 3P
= -60 + 3(45)
= 75 units
They would be supplying less units and be hurt.
