  2. Marginal utility - Wikipedia

    en.wikipedia.org/wiki/Marginal_utility

    Diamonds are priced higher than water because their marginal utility is higher than water. [ 33 ] Eighteenth-century Italian mercantilists , such as Antonio Genovesi , Giammaria Ortes , Pietro Verri , Marchese Cesare di Beccaria , and Count Giovanni Rinaldo Carli , held that value was explained in terms of the general utility and of scarcity ...

  3. Allocative efficiency - Wikipedia

    en.wikipedia.org/wiki/Allocative_efficiency

    Therefore, the market equilibrium, where demand meets supply, is also where the marginal social benefit equals the marginal social costs. At this point, the net social benefit is maximized, meaning this is the allocative efficient outcome. When a market fails to allocate resources efficiently, there is said to be market failure.

  4. Economic efficiency - Wikipedia

    en.wikipedia.org/wiki/Economic_efficiency

    A market can be said to have allocative efficiency if the price of a product that the market is supplying is equal to the marginal value consumers place on it, and equals marginal cost. In other words, when every good or service is produced up to the point where one more unit provides a marginal benefit to consumers less than the marginal cost ...

  5. Marginalism - Wikipedia

    en.wikipedia.org/wiki/Marginalism

    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.

  6. Groundwater banking - Wikipedia

    en.wikipedia.org/wiki/Groundwater_banking

    The different projects can become economically efficient by maximizing the benefits of the limited resource (water). [9] To maximize efficiency the users need to find where marginal cost is equal to marginal benefit. [9] It is important for supply to equal demand like in the figure below.

  7. Marginal concepts - Wikipedia

    en.wikipedia.org/wiki/Marginal_concepts

    A marginal benefit is a benefit (howsoever ranked or measured) associated with a marginal change. The term “marginal cost” may refer to an opportunity cost at the margin, or more narrowly to marginal pecuniary cost — that is to say marginal cost measured by forgone cash flow. Other marginal concepts include (but are not limited to):

  8. Lindahl tax - Wikipedia

    en.wikipedia.org/wiki/Lindahl_tax

    In a Lindahl equilibrium, the optimal quantity of the public good will be where the social marginal benefit intersects the marginal cost (point P). Each individual's Lindahl tax rate will be based on their own marginal benefit curve. In this model, individual B will pay the price level at R and individual A will pay at point J.

  9. Margin (economics) - Wikipedia
