  3. Finite difference methods for option pricing - Wikipedia

    en.wikipedia.org/wiki/Finite_difference_methods...

    The discrete difference equations may then be solved iteratively to calculate a price for the option. [4] The approach arises since the evolution of the option value can be modelled via a partial differential equation (PDE), as a function of (at least) time and price of underlying; see for example the Black–Scholes PDE. Once in this form, a ...

    [7] [8] [2] Price discrimination is distinguished from product differentiation by the difference in production cost for the differently priced products involved in the latter strategy. [2] Price discrimination essentially relies on the variation in customers' willingness to pay [8] [2] [4] and in the elasticity of their demand.

    Verification is intended to check that a product, service, or system meets a set of design specifications. [6] [7] In the development phase, verification procedures involve performing special tests to model or simulate a portion, or the entirety, of a product, service, or system, then performing a review or analysis of the modeling results.

  7. Gratis versus libre - Wikipedia

    en.wikipedia.org/wiki/Gratis_versus_libre

    "Gratis" pertains to being able to access and use the code, without a price-barrier, while "libre" pertains to being allowed to modify and re-use the code, without a permission barrier. The target content of the open access movement, however, is not software but published, peer-reviewed research journal article texts.

  8. Law of one price - Wikipedia

    en.wikipedia.org/wiki/Law_of_one_price

    Although there is a small spread between these two values the law of one price applies (to each). No trader will sell the commodity at a lower price than the market maker's bid-level or buy at a higher price than the market maker's offer-level. [8] In either case moving away from the prevailing price would either leave no takers, or be charity.

  9. Relative price - Wikipedia

    en.wikipedia.org/wiki/Relative_price

    A relative price is the price of a commodity such as a good or service in terms of another; i.e., the ratio of two prices. A relative price may be expressed in terms of a ratio between the prices of any two goods or the ratio between the price of one good and the price of a market basket of goods (a weighted average of the prices of all other goods available in the market).
