Solution
a
Definition of Economies of Scale: Economies of scale occur when increasing the scale of production leads to a lower cost per unit of output
b
Analysis of Answer Choices: - (A) is incorrect because not all costs need to be implicit for economies of scale to occur. - (B) is incorrect because a flat long-run average total cost curve indicates constant returns to scale, not economies of scale. - (C) is correct because if Dineo Enterprises is experiencing economies of scale, increasing output will lead to a decrease in long-run average total cost. - (D) is incorrect because economic profits are not directly related to economies of scale; they depend on market conditions and other factors. - (E) is incorrect because proportionate increases in inputs resulting in proportionate increases in outputs describe constant returns to scale, not economies of scale
Answer
(C) Long-run average total cost decreases if Dineo Enterprises increases output.
Key Concept
Economies of Scale
Explanation
When a firm experiences economies of scale, its long-run average total cost decreases as it increases output. This is due to factors such as specialization, bulk buying, and spreading fixed costs over a larger number of units.
