  2. Marginal cost - Wikipedia

    en.wikipedia.org/wiki/Marginal_cost

    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 ...

  3. Profit maximization - Wikipedia

    In other words, the rule is that the size of the markup of price over the marginal cost is inversely related to the absolute value of the price elasticity of demand for the good. [10] The optimal markup rule also implies that a non-competitive firm will produce on the elastic region of its market demand curve. Marginal cost is positive.

  4. Margin (economics) - Wikipedia

    en.wikipedia.org/wiki/Margin_(economics)

    Money portal. v. t. e. 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.

  5. Public good (economics) - Wikipedia

    en.wikipedia.org/wiki/Public_good_(economics)

    These marginal valuations are, formally, marginal rates of substitution relative to some reference private good, and the marginal cost is a marginal rate of transformation that describes how much of that private good it costs to produce an incremental unit of the public good. This contrasts to the social optimality condition of private goods ...

  6. Cost curve - Wikipedia

    en.wikipedia.org/wiki/Cost_curve

    The total cost curve, if non-linear, can represent increasing and diminishing marginal returns.. The short-run total cost (SRTC) and long-run total cost (LRTC) curves are increasing in the quantity of output produced because producing more output requires more labor usage in both the short and long runs, and because in the long run producing more output involves using more of the physical ...

  7. Variable cost - Wikipedia

    en.wikipedia.org/wiki/Variable_cost

    Variable costs are costs that change as the quantity of the good or service that a business produces changes. [ 1] Variable costs are the sum of marginal costs over all units produced. They can also be considered normal costs. Fixed costs and variable costs make up the two components of total cost. Direct costs are costs that can easily be ...

  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. Marginalism - Wikipedia

    en.wikipedia.org/wiki/Marginalism

    v. t. e. Marginalism is a theory of economics that attempts to explain the discrepancy in the value of goods and services by reference to their secondary, or marginal, utility. It states that the reason why the price of diamonds is higher than that of water, for example, owes to the greater additional satisfaction of the diamonds over the water.
