  2. Excludability - Wikipedia

    en.wikipedia.org/wiki/Excludability

    A classic example of the inefficiency caused by non-excludability is the tragedy of the commons (which Hardin, the author, later corrected to the 'tragedy of the unmanaged commons' because it is based on the notion of an entirely rule-less resource) where a shared, non-excludable, resource becomes subject to over-use and over-consumption, which ...

  3. Public good - Wikipedia

    en.wikipedia.org/wiki/Public_good

    His argument was that people would pay for the public goods according to the way they benefit from the good. The more a person benefits from these goods, the higher the amount they pay. People are more willing to pay for goods that they value. Taxes are needed to fund public goods and people are willing to bear the burden of taxes. [11]

  4. Utility functions on divisible goods - Wikipedia

    en.wikipedia.org/wiki/Utility_functions_on...

    This page compares the properties of several typical utility functions of divisible goods. These functions are commonly used as examples in consumer theory . The functions are ordinal utility functions, which means that their properties are invariant under positive monotone transformation .

  5. Price discrimination - Wikipedia

    en.wikipedia.org/wiki/Price_discrimination

    Gender-based price discrimination is the practice of offering identical or similar services and products to men and women at different prices when the cost of producing the products and services is the same. [52] In the United States, gender-based price discrimination has been a source of debate. [53]

  6. Fair item allocation - Wikipedia

    en.wikipedia.org/wiki/Fair_item_allocation

    Fair item allocation is a kind of the fair division problem in which the items to divide are discrete rather than continuous. The items have to be divided among several partners who potentially value them differently, and each item has to be given as a whole to a single person. [1] This situation arises in various real-life scenarios:

  7. Positional good - Wikipedia

    en.wikipedia.org/wiki/Positional_good

    Positional goods are goods valued only by how they are distributed among the population, not by how many of them there are available in total (as would be the case with other consumer goods). The source of greater worth of positional goods is their desirability as a status symbol , which usually results in them greatly exceeding the value of ...

  8. Indifference curve - Wikipedia

    en.wikipedia.org/wiki/Indifference_curve

    As used in biology, the indifference curve is a model for how animals 'decide' whether to perform a particular behavior, based on changes in two variables which can increase in intensity, one along the x-axis and the other along the y-axis. For example, the x-axis may measure the quantity of food available while the y-axis measures the risk ...

  9. Ordinal utility - Wikipedia

    en.wikipedia.org/wiki/Ordinal_utility

    It can be shown that consumer analysis with indifference curves (an ordinal approach) gives the same results as that based on cardinal utility theory — i.e., consumers will consume at the point where the marginal rate of substitution between any two goods equals the ratio of the prices of those goods (the equi-marginal principle).
