  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. 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 ...

  4. Marginal revenue - Wikipedia

    en.wikipedia.org/wiki/Marginal_revenue

    Marginal revenue is the concept of a firm sacrificing the opportunity to sell the current output at a certain price, in order to sell a higher quantity at a reduced price. [8] Profit maximization occurs at the point where marginal revenue (MR) equals marginal cost (MC). If then a profit-maximizing firm will increase output to generate more ...

  5. Marginal product of labor - Wikipedia

    en.wikipedia.org/wiki/Marginal_product_of_labor

    Marginal cost (MC) is the change in total cost per unit change in output or ∆ C /∆ Q. In the short run, production can be varied only by changing the variable input. Thus only variable costs change as output increases: ∆ C = ∆ VC = ∆ ( wL ). Marginal cost is ∆ ( Lw )/∆ Q. Now, ∆ L /∆ Q is the reciprocal of the marginal product ...

  6. 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.

  7. Diminishing returns - Wikipedia

    en.wikipedia.org/wiki/Diminishing_returns

    Similarly, if the third kilogram of seeds yields only a quarter ton, then the marginal cost equals per quarter ton or per ton, and the average cost is per 7/4 tons, or /7 per ton of output. Thus, diminishing marginal returns imply increasing marginal costs and increasing average costs. Cost is measured in terms of opportunity cost. In this case ...

  8. 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.

  9. 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 ...
