Answer:
Given:
Monopolist earns = $60 million
The opportunity cost of funds = 18 %
The monopolist will earn = $20 million after another firm enters the market
The present value of the monopolist’s current and future earnings if entry occurs can be computed using the following formula:




The present value of the monopolist’s is $171.1 million
If the monopolist can earn $35 million indefinitely by limit pricing,then the present value of the monopolist’s current earnings:



∴ If the monopolist can earn $35 million indefinitely by limit pricing, then they should do so.
