A firm is operating beyond minimum efficient scale in a perfectly competitive industry. To maintain long-term viability, the most likely course of action for the firm is to:
A. operate at the current level of production.
B. increase its level of production to gain economies of scale.
C. decrease its level of production to the minimum point on the long-run average total cost curve.
The correct answer and explanation is :
The correct answer is C. decrease its level of production to the minimum point on the long-run average total cost curve.
Explanation:
In a perfectly competitive market, firms are driven by the need to minimize their long-run average total costs (LRATC) to remain profitable and competitive. The minimum efficient scale (MES) refers to the smallest quantity of output at which a firm can produce at the lowest possible average total cost (ATC) in the long run.
If a firm is operating beyond the minimum efficient scale, it suggests that it is producing at a point where its production costs are higher than they could be at the MES. In the long run, firms in a perfectly competitive market cannot sustain any level of production that does not allow them to cover their costs and earn normal profits. In this case, the firm’s long-run average total cost curve is downward-sloping, indicating that as the firm increases its output, it benefits from economies of scale. However, if it is already beyond the MES, the firm has likely passed the point of optimal production where further increases in output lead to diseconomies of scale (higher per-unit costs).
To maintain long-term viability, the firm must aim to operate at the minimum point on the LRATC curve where the average total cost is at its lowest. By doing so, the firm would be able to minimize its costs and remain competitive in the market. If the firm continues operating beyond the MES, it risks producing at a higher cost than necessary, making it vulnerable to competition from other firms that may be operating at lower costs.
The other options are not viable:
- Option A: If the firm continues operating at the current production level beyond the MES, it may incur inefficiencies and face higher costs than competitors.
- Option B: Increasing production further would lead to diseconomies of scale, raising costs rather than lowering them.
Thus, the best strategy is to decrease the production level to the point where the firm can operate at the MES and achieve the lowest possible cost.
