Answer: The monopolist will be able to sustain economic profits
Step-by-step explanation:
If a monopolist in an industry characterized by monopoly features is making economic profit in the short run, then the monopolist will be able to sustain economic profits.
The economic profit is gotten when the explicit cost and the opportunity costs are both deducted from the revenues generated by a business.
Since there is high barrier to entry and the monopoly is the only firm in the market, then the monopolist will be able to sustain economic profits.
