Question

1.Suppose a monopolist faces the demand curve P = 153 - 1Q. The monopolist's marginal costs are a constant $16 and they have fixed costs equal to $146. Given this information, what will the profit-maximizing price be for this monopolist?

Round your answer to two decimal places. Do not use a $ sign.

2. Suppose a monopolist faces the demand curve P = 195 - 1Q. The monopolist's marginal costs are a constant $32 and they have fixed costs equal to $58. Given this information, what are the maximum profits this firm can earn?

Round your answer to two decimal places. Do not use a $ sign.

3. Suppose a monopolist faces the demand curve P = 187 - 4Q. The monopolist's marginal costs are a constant $27 and they have fixed costs equal to $69. Given this information, if the firm maximizes their profits, what would be size of the deadweight loss in this market?

Explanation / Answer

1. P = 153 - 1Q

TR = P*Q = 153 Q - 1Q2

MR = dTR/dQ = 153 - 2Q

MC = 16

TC = FC + MC*Q = 146 + 16Q

Profit maximises at equilibrum where MC = MR
153 - 2Q = 16

2Q = 137

Q = 68.5

P = 153 - 68.5 = 84.5

2. P = 195 - 1Q.

TR = 195Q - 1Q2

MR = 195 - 2Q.

MC = 32

At equilibrium, 195 - 2Q = 32

2Q = 163

Q = 81.5

P = 195 - 81.5 = 113.5

TR = 113.5 * 81.5 = 9250.25

TC = 58 + 32Q

TC = 58 + 32 * 81.5

TC = 2666

Profit = TR - TC

Profit = 6584.25

3. P = 187 - 4Q

TR = 187Q - 4 Q2

MR = 187 - 8Q

MC = 27

AT equilibrium, 187 - 8Q = 27

8Q = 160

Qm = 20

P = 187 - 4* 20

Pm = 107

Takinh this case as under perfect competition, P = MR

SO putting, P = MC under equilibirum condition, 187 - 4Q = 27

4Q = 160

Q = 40

P = 187 - 4*40

P = 27

Dead weight Loss = 1/2 x (DIfference in price) x (Difference in Qunatity)

DWL = 1/2 x 107 - 27) x (40 - 20)

DWL = 1/2 x 80 x 20

DWL = 800
