  7. What will be the total cost of this subsidy paid by the government?
  8. Calculate DWL under subsidy.

Homework Answers

Answer #1

(1)

In equilibrium, Qd = Qs.

20 - 2P = 4P - 10

6P = 30

P = $5

Q = 20 - (2 x 5) = 20 - 10 = 10

(2)

Ed = (dQd/dP) x (P/Qd) = -2 x (5/10) = -1

Es = (dQs/dP) x (P/Qs) = 4 x (5/10) = 2

(3)

Tax burden of buyers = Es / (Ed** + Es) = 2 / (1 + 2) = 2 / 3 = 0.67 = $1 x 0.67 = $0.67

Tax burden of sellers = Ed** / (Ed** + Es) = 1 / (1 + 2) = 1 / 3 = 0.33 = $1 x 0.33 = $0.33

**Absolute value of elasticity of demand is considered.

(4)

The $1 tax will increase effective price paid by buyers, which will decrease demand. New demand function will be

Qd = 20 - 2(P + 1) = 20 - 2P - 2 = 18 - 2P

Equating with Qs,

18 - 2P = 4P - 10

6P = 28

P = $4.67 (Price received by sellers)

Price paid by buyers = $4.67 + $1 = $5.67

Q = (4 x 4.67) - 10 = 18.68 - 10 = 8.68

(5)

DWL = (1/2) x Unit tax x Change in quantity = (1/2) x $1 x (10 - 8.68) = $0.5 x 1.32 = $0.66
