Question

Explain the conditions required for profit maximization of a perfectly competitive firm in short run.

Hint:

In perfect competition, profit maximization is achieved when MC = MR. If this condition is not met, the firm should adjust its output level.

Answer 1

Step 1: Define profit maximization.
Profit maximization occurs when a firm's total revenue exceeds its total cost by the greatest possible amount.
Step 2: Conditions for profit maximization.
The conditions for profit maximization of a perfectly competitive firm in the short run are: 1. Marginal Cost (MC) equals Marginal Revenue (MR): In perfect competition, a firm maximizes profit when MC = MR. At this point, the firm is producing the optimal quantity of output. 2. MC curve must be rising: The firm must be producing at the point where the MC curve is rising and intersects the MR curve. 3. Average Cost (AC) curve behavior: For the firm to earn maximum profit, the price (which is equal to MR in perfect competition) should be above the AC curve. If the price is below the AC curve, the firm incurs losses. If the price equals the AC curve, the firm breaks even. 4. No loss condition: If the firm is producing at the point where MC = MR and the price is above the AC curve, the firm is maximizing its short-run profit.
