The profit-maximizing level of output for a perfectly competitive firm:A perfectly competitive firm is a price taker and has no control over the market price of the product it sells.
- The firm's marginal revenue curve is perfectly horizontal and is equal to the market price.
- The profit-maximizing level of output occurs where the firm's marginal revenue (MR) equals its marginal cost (MC).
- If the marginal cost is less than the market price, the firm should produce more to earn a profit on each additional unit produced.
- If the marginal cost is greater than the market price, the firm should produce less to avoid losing money on each additional unit produced.
- The profit-maximizing level of output for a perfectly competitive firm occurs at the point where the marginal cost curve intersects the marginal revenue curve (which is perfectly horizontal and equal to the market price).
- This level of output is also referred to as the efficient level of production, because it maximizes the firm's profit while minimizing the cost of production.
Let's say that a perfectly competitive firm produces and sells widgets in a market where the market price for a widget is $5. The firm's marginal cost to produce each widget is shown in the following table:
| Quantity | Total Cost | Marginal Cost |
|---|
| 1 | $5 | $5 |
| 2 | $8 | $3 |
| 3 | $11 | $3 |
| 4 | $15 | $4 |
| 5 | $20 | $5 |
| 6 | $26 | $6 |
To determine the profit-maximizing level of output, the firm needs to compare its marginal cost to the market price of $5.
At a quantity of 1, the marginal cost is equal to the market price of $5, so the firm should produce and sell this quantity.
At a quantity of 2, the marginal cost is less than the market price, so the firm should continue to produce and sell more widgets.
At a quantity of 3, the marginal cost is still less than the market price, so the firm should continue to produce and sell more widgets.
At a quantity of 4, the marginal cost is greater than the market price, so the firm should not produce and sell any more widgets beyond this point.
Therefore, the profit-maximizing level of output for this perfectly competitive firm is a quantity of 3 widgets, where the marginal cost is equal to the market price of $5. At this level of output, the firm will earn a profit on each additional widget produced and sold. Any production beyond this point would result in losses for the firm.
