  2. Marginal cost - Wikipedia

    en.wikipedia.org/wiki/Marginal_cost

    Marginal cost is the change of the total cost from an additional output [(n+1)th unit]. Therefore, (refer to "Average cost" labelled picture on the right side of the screen. Average cost. In this case, when the marginal cost of the (n+1)th unit is less than the average cost(n), the average cost (n+1) will get a smaller value than average cost(n).

  3. Marginal product of labor - Wikipedia

    en.wikipedia.org/wiki/Marginal_product_of_labor

    The marginal product of labor is directly related to costs of production. Costs are divided between fixed and variable costs. Fixed costs are costs that relate to the fixed input, capital, or rK, where r is the rental cost of capital and K is the quantity of capital. Variable costs (VC) are the costs of the variable input, labor, or wL, where w ...

  4. Social cost - Wikipedia

    en.wikipedia.org/wiki/Social_cost

    Mathematically, social marginal cost is the sum of private marginal cost and the external costs. [3] For example, when selling a glass of lemonade at a lemonade stand, the private costs involved in this transaction are the costs of the lemons and the sugar and the water that are ingredients to the lemonade, the opportunity cost of the labor to combine them into lemonade, as well as any ...

  5. Managerial economics - Wikipedia

    Production analysis. The input of production factors, the choice of the form of production organisation and the determination of the product structure can all be analysed and decided by creating mathematical models. Cost decision. Cost is a factor that directly affects profit, and is one of the most important concerns for enterprise development.

  6. Allocative efficiency - Wikipedia

    en.wikipedia.org/wiki/Allocative_efficiency

    Allocative efficiency is a state of the economy in which production is aligned with the preferences of consumers and producers; in particular, the set of outputs is chosen so as to maximize the social welfare of society. [1] This is achieved if every produced good or service has a marginal benefit equal to the marginal cost of production.

  7. Average cost - Wikipedia

    en.wikipedia.org/wiki/Average_cost

    A typical average cost curve has a U-shape, because fixed costs are all incurred before any production takes place and marginal costs are typically increasing, because of diminishing marginal productivity. In this "typical" case, for low levels of production marginal costs are below average costs, so average costs are decreasing as quantity ...

  8. Marginal product - Wikipedia

    en.wikipedia.org/wiki/Marginal_product

    Average physical product (APP), marginal physical product (MPP) In economics and in particular neoclassical economics, the marginal product or marginal physical productivity of an input (factor of production) is the change in output resulting from employing one more unit of a particular input (for instance, the change in output when a firm's labor is increased from five to six units), assuming ...

  9. Opportunity cost - Wikipedia

    en.wikipedia.org/wiki/Opportunity_cost

    Marginal cost: The increase in cost caused by an additional unit of production is called marginal cost. By definition, marginal cost (MC) is equal to the change in total cost ( TC) divided by the corresponding change in output ( Q): MC(Q) = TC(Q)/ Q or, taking the limit as Q goes to zero, MC(Q) = lim( Q→0) TC(Q)/ Q = dTC/dQ. In theory ...
