In a typical intertemporal consumption model, the above summation of utilities discounted from various future times would be maximized with respect to the amounts x t consumed in each period, subject to an intertemporal budget constraint that says that the present value of current and future expenditures does not exceed the present value of ...
In finance, discounting is a mechanism in which a debtor obtains the right to delay payments to a creditor, for a defined period of time, in exchange for a charge or fee. [1] Essentially, the party that owes money in the present purchases the right to delay the payment until some future date. [ 2 ]
In quantitative finance, a lattice model [1] is a mathematical approach to the valuation of derivatives in situations requiring a discrete time model. For dividend paying equity options , a typical application would correspond to the pricing of an American-style option , where a decision to exercise is allowed at any time up to the maturity.
In economics, a discount function is used in economic models to describe the weights placed on rewards received at different points in time. For example, if time is discrete and utility is time-separable, with the discount function f(t) having a negative first derivative and with c t (or c(t) in continuous time) defined as consumption at time t, total utility from an infinite stream of ...
Discounts and allowances are reductions to a basic price of goods or services.. They can occur anywhere in the distribution channel, modifying either the manufacturer's list price (determined by the manufacturer and often printed on the package), the retail price (set by the retailer and often attached to the product with a sticker), or the list price (which is quoted to a potential buyer ...

Exponential discounting is not dynamically inconsistent. A key aspect of the exponential discounting assumption is the property of dynamic consistency— preferences are constant over time. [1] In other words, preferences do not change with the passage of time unless new information is presented.
Time value of money problems involve the net value of cash flows at different points in time. In a typical case, the variables might be: a balance (the real or nominal value of a debt or a financial asset in terms of monetary units), a periodic rate of interest, the number of periods, and a series of cash flows. (In the case of a debt, cas
