  2. 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 .

  3. Shephard's lemma - Wikipedia

    en.wikipedia.org/wiki/Shephard's_lemma

    The idea is that a consumer will buy a unique ideal amount of each item to minimize the price for obtaining a certain level of utility given the price of goods in the market. The lemma is named after Ronald Shephard , who proved it using the distance formula in his book Theory of Cost and Production Functions in 1953.

  4. Cost of goods available for sale - Wikipedia

    en.wikipedia.org/wiki/Cost_of_Goods_Available...

    Cost of goods available for sale is the maximum amount of goods, or inventory, that a company can possibly sell during an accounting period.It has the formula: [1] Beginning Inventory (at the start of accounting period) + purchases (within the accounting period) + Production (within the accounting period) = cost of goods available for sale

  5. Price discrimination - Wikipedia

    en.wikipedia.org/wiki/Price_discrimination

    Many forms of price discrimination are legal, but in some cases charging consumers different prices for the same goods is illegal. For example, in the United States, the Robinson–Patman Act makes price discrimination illegal in certain anti-competitive interstate sale of commodities.

  6. Supply and demand - Wikipedia

    en.wikipedia.org/wiki/Supply_and_demand

    Supply chain as connected supply and demand curves. In microeconomics, supply and demand is an economic model of price determination in a market.It postulates that, holding all else equal, the unit price for a particular good or other traded item in a perfectly competitive market, will vary until it settles at the market-clearing price, where the quantity demanded equals the quantity supplied ...

  7. Law of supply - Wikipedia

    en.wikipedia.org/wiki/Law_of_supply

    A supply is a good or service that producers are willing to provide. The law of supply determines the quantity of supply at a given price. [5]The law of supply and demand states that, for a given product, if the quantity demanded exceeds the quantity supplied, then the price increases, which decreases the demand (law of demand) and increases the supply (law of supply)—and vice versa—until ...

  8. Price mechanism - Wikipedia

    en.wikipedia.org/wiki/Price_mechanism

    A whole set of prices prevail in such an economy. Goods and services are available at a price because it involves cost in producing these goods and services. Consumers have to pay some prices if they want to buy some goods like food, clothes, etc. Producers are willing to sell goods and services only if they get the appropriate price. 2.

  9. Indirect utility function - Wikipedia

    en.wikipedia.org/wiki/Indirect_utility_function

    A consumer's indirect utility (,) can be computed from their utility function (), defined over vectors of quantities of consumable goods, by first computing the most preferred affordable bundle, represented by the vector (,) by solving the utility maximization problem, and second, computing the utility ((,)) the consumer derives from that ...
