  2. Agile contracts - Wikipedia

    en.wikipedia.org/wiki/Agile_contracts

    The model introduces an initial test phase after which budget, due date, and the way of steering the scope within the framework is agreed upon. This differs from traditional fixed-price contracts in that fixed-price contracts usually require a detailed and exact description of the subject matter of the contract in advance. Fixed price contracts ...

  3. Calvo (staggered) contracts - Wikipedia

    en.wikipedia.org/wiki/Calvo_(staggered)_contracts

    After any finite time, there will still be some proportion of prices that have not responded and remained fixed. This contrasts with the Taylor model, where there is a fixed length for contracts - for example 4 periods. After 4 periods, firms will have reset their price. The Calvo pricing model played a key role in the derivation of the New ...

  4. Finite difference methods for option pricing - Wikipedia

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

    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 finite difference model can be derived, and the valuation obtained. [2]

  5. Asset pricing - Wikipedia

    en.wikipedia.org/wiki/Asset_pricing

    In financial economics, asset pricing refers to a formal treatment and development of two interrelated pricing principles, [1] [2] outlined below, together with the resultant models. There have been many models developed for different situations, but correspondingly, these stem from either general equilibrium asset pricing or rational asset ...

    According to the PMBOK (7th edition) by the Project Management Institute (PMI), Fixed Price Economic Price Adjustment Contract (FPEPA) is a "fixed-price contract, but with a special provision allowing for predefined final adjustments to the contract price due to changed conditions, such as inflation changes, or cost increases (or decrease) for special commodities".

  9. Pricing schedule - Wikipedia

    en.wikipedia.org/wiki/Pricing_schedule

    Affine Pricing - An affine pricing schedule consists of both a fixed cost and a cost per unit. Using the same notation as above, T(q) = k + pq, where k is a constant cost . [ 3 ]
