6. What is the profit maximization condition for a monopoly?
Answer: A
Monopolies maximize profit when marginal revenue equals marginal cost.
Profit maximization for a monopoly occurs at the point where marginal revenue (MR) equals marginal cost (MC). This condition ensures that the firm is producing the optimal quantity of output where the cost of producing one more unit is exactly balanced by the revenue gained from selling that unit.
A) When marginal revenue equals marginal cost
This statement accurately describes the profit maximization condition for a monopoly. At this point, the monopoly maximizes its profits because producing beyond this point would lead to a decrease in overall profit as the cost of producing an additional unit would exceed the revenue gained from selling it.
B) When marginal cost is minimized
This option is incorrect because minimizing marginal cost does not necessarily lead to profit maximization. A firm may have low marginal costs but still not be maximizing profit if marginal revenue does not equal marginal cost at that output level.
C) When total revenues are maximized
While maximizing total revenues may seem beneficial, it does not guarantee profit maximization. A monopoly could maximize total revenues while still incurring high costs, leading to lower profits. Profit maximization specifically requires the balance of marginal revenue and marginal cost.
D) When price equals marginal cost
This statement is characteristic of perfect competition, not monopoly. In a monopoly, the price is typically set above marginal cost due to the market power held by the monopolist. Therefore, this condition does not reflect the profit maximization strategy of a monopoly.
Conclusion
The correct answer is A, as it directly addresses the fundamental principle of profit maximization in monopolistic markets. All other options either misinterpret the conditions for profit maximization or apply to different market structures, confirming that only the equality of marginal revenue and marginal cost accurately defines the profit-maximizing behavior of a monopoly.
