Answer:
(a) $227
(b) $112
(c) $77.31
Explanation:
(a) Under a monopoly market conditions, the optimum level of production is at a point where marginal revenue is equal to the marginal cost.
We know that MR = P(1 + 1/ed).
This implies MC = P(1 + 1/ed)
75 = P(1 - 1/1.5)
P = $227
Hence, the optimal per unit price in this case is $227.
b) In a cournot oligopoly, firm's elasticity of demand is the product of market elasticity and number of firms in the market.
For n = 2,
own price elasticity = -1.5 × 2
= -3
Use the same rule
MC = P(1 + 1/ed)
75 = P(1 - 1/3)
P = $112
Hence, the optimal per unit price in this case is $112.
c) For n = 19, own price elasticity = -1.5 × 20
= -30.
Use the same rule
MC = P(1 + 1/ed)
75 = P(1 - 1/30)
P = $77.31
Hence, the optimal per unit price in this case is $77.31
