  2. Cost curve - Wikipedia

    en.wikipedia.org/wiki/Cost_curve

    The marginal cost curve is usually U-shaped. Marginal cost is relatively high at small quantities of output; then as production increases, marginal cost declines, reaches a minimum value, then rises. The marginal cost is shown in relation to marginal revenue (MR), the incremental amount of sales revenue that an additional unit of the product or ...

  3. Marginal revenue - Wikipedia

    en.wikipedia.org/wiki/Marginal_revenue

    The marginal revenue curve is affected by the same factors as the demand curve – changes in income, changes in the prices of complements and substitutes, changes in populations, etc. [15] These factors can cause the MR curve to shift and rotate. [16] Marginal revenue curve differs under perfect competition and imperfect competition (monopoly ...

  4. Monopolistic competition - Wikipedia

    en.wikipedia.org/wiki/Monopolistic_competition

    The company maximises its profits and produces a quantity where the company's marginal revenue (MR) is equal to its marginal cost (MC). The company is able to collect a price based on the average revenue (AR) curve. The difference between the company's average revenue and average cost, multiplied by the quantity sold (Qs), gives the total profit.

  5. Marginal cost - Wikipedia

    en.wikipedia.org/wiki/Marginal_cost

    In economics, the marginal cost is the change in the total cost that arises when the quantity produced is increased, i.e. the cost of producing additional quantity. [1] In some contexts, it refers to an increment of one unit of output, and in others it refers to the rate of change of total cost as output is increased by an infinitesimal amount.

  6. Profit maximization - Wikipedia

    en.wikipedia.org/wiki/Profit_maximization

    Marginal cost and marginal revenue, depending on whether the calculus approach is taken or not, are defined as either the change in cost or revenue as each additional unit is produced or the derivative of cost or revenue with respect to the quantity of output. For instance, taking the first definition, if it costs a firm $400 to produce 5 units ...

  7. Perfect competition - Wikipedia

    en.wikipedia.org/wiki/Perfect_competition

    Such markets are allocatively efficient, as output will always occur where marginal cost is equal to average revenue i.e. price (MC = AR). In perfect competition, any profit-maximizing producer faces a market price equal to its marginal cost (P = MC). This implies that a factor's price equals the factor's marginal revenue product.

  8. Total cost - Wikipedia

    en.wikipedia.org/wiki/Total_cost

    The additional total cost of one additional unit of production is called marginal cost. 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. The total ...

  9. Monopoly price - Wikipedia

    en.wikipedia.org/wiki/Monopoly_price

    Marginal cost (MC) relates to the firm's technical cost structure within production, and indicates the rise in total cost that must occur for an additional unit to be supplied to the market by the firm. [1] The marginal cost is higher than the average cost because of diminishing marginal product in the short run. [1]
