In microeconomics, marginal profit is the increment to profit resulting from a unit or infinitesimal increment to the quantity of a product produced. Under the marginal approach to profit maximization , to maximize profits, a firm should continue to produce a good or service up to the point where marginal profit is zero.
or "marginal revenue" = "marginal cost". A firm with market power will set a price and production quantity such that marginal cost equals marginal revenue. A competitive firm's marginal revenue is the price it gets for its product, and so it will equate marginal cost to price. (′ / +) =
Note the strange presence of 'x' in the model. Notice also that the absorption model (equation 10) is the same as the marginal costing model (equation 9) except for the end part: F/x p * (q-x 1) This part represents the fixed costs in stock. This is better seen by remem¬bering q — x= go—g1 so it could be written F/x p • (g 0 —g 1)
Profit maximization requires that a firm produces where marginal revenue equals marginal costs. Firm managers are unlikely to have complete information concerning their marginal revenue function or their marginal costs. However, the profit maximization conditions can be expressed in a “more easily applicable form”: MR = MC, MR = P(1 + 1/e),
The marginal cost can also be calculated by finding the derivative of total cost or variable cost. Either of these derivatives work because the total cost includes variable cost and fixed cost, but fixed cost is a constant with a derivative of 0.
If the marginal revenue is greater than the marginal cost (>), then its total profit is not maximized, because the firm can produce additional units to earn additional profit. In other words, in this case, it is in the "rational" interest of the firm to increase its output level until its total profit is maximized.
The different curves are developed based on the costs of production, specifically the graph contains marginal cost, average total cost, average variable cost, average fixed cost, and marginal revenue, which is sometimes equal to the demand, average revenue, and price in a price-taking firm.
Within economics, margin is a concept used to describe the current level of consumption or production of a good or service. [1] Margin also encompasses various concepts within economics, denoted as marginal concepts, which are used to explain the specific change in the quantity of goods and services produced and consumed.
