determine the consumer and producer surplus when we have the equations of: supply: P=p=2q^2/3 + 32 Demand: P=-1/3q^2/3 + 53
Question
Answer:
To determine the consumer and producer surplus, we first need to find the equilibrium price and quantity at which the supply and demand curves intersect. The consumer surplus is then calculated based on the demand curve, while the producer surplus is calculated based on the supply curve.
Given the supply and demand equations:
Supply: P = 2q^(2/3) + 32
Demand: P = -(1/3)q^(2/3) + 53
Set the two equations equal to each other to find the equilibrium price and quantity:
2q^(2/3) + 32 = -(1/3)q^(2/3) + 53
Now, solve for q:
2q^(2/3) + (1/3)q^(2/3) = 53 - 32
(2 + 1/3)q^(2/3) = 21
(7/3)q^(2/3) = 21
Now, divide by (7/3) to solve for q:
q^(2/3) = (21 * 3)/7
q^(2/3) = 63/7
Now, take the cube root of both sides:
q = (63/7)^(3/2)
q = (3 * 3^(1/2))^3
q = 3^4 * 3^(1/2)
q = 3^(4 + 1/2)
q = 3^(9/2)
q = 27β3
Now that we have the equilibrium quantity, we can find the equilibrium price by substituting this value into either the supply or demand equation. Let's use the supply equation:
P = 2(27β3)^(2/3) + 32
P = 2(27)^(2/3) + 32
P = 2(3^3)^(2/3) + 32
P = 2(3^(3*(2/3))) + 32
P = 2(3^2) + 32
P = 18 + 32
P = 50
So, the equilibrium price (P) is 50, and the equilibrium quantity (q) is 27β3.
Now, let's calculate the consumer surplus and producer surplus:
Consumer Surplus (CS):
Consumer surplus represents the area between the demand curve and the price level up to the equilibrium price. It is calculated as the area of a triangle:
CS = (1/2) * (base) * (height)
Base = 27β3
Height = (53 - 50) = 3
CS = (1/2) * (27β3) * 3
CS = 40.5β3 = 70.148
Producer Surplus (PS):
Producer surplus represents the area between the supply curve and the price level down to the equilibrium price. It is also calculated as the area of a triangle:
PS = (1/2) * (base) * (height)
Base = 27β3
Height = (50 - 32) = 18
PS = (1/2) * (27β3) * 18
PS = 243β3 = 420.888
So, the consumer surplus is approximately 40.5β3, and the producer surplus is approximately 243β3.
