A constant function represents an action's utility that is not related to the action's completion time—for example, the action's constant relative importance. This allows both time-dependent and time-independent actions to be scheduled coherently. A TUF has a global critical time, after which its utility does not increase. If a TUF never ...

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
A separate term for the aggregation of expenses and losses does not exist. Contra-accounts are accounts with negative balances that offset other balance sheet accounts. Examples are accumulated depreciation (offset against fixed assets), and the allowance for bad debts (offset against accounts receivable). Deferred interest is also offset ...
A quantity of money invested today costs ′ units of utility, and so must yield exactly that number of units of utility in the future when saved at the prevailing gross interest rate = +, where is the net interest rate (if it yielded more, then the agent could make himself better off by saving more).
For example, a company may have unexpected and unpredictable expenses unrelated to production, such as warehouse costs and the like that are fixed only over the time period of the lease. By definition, there are no fixed costs in the long run, because the long run is a sufficient period of time for all short-run fixed inputs to become variable.
It is calculated as the present discounted value of future utility, and for people with time preference for sooner rather than later gratification, it is less than the future utility. The utility of an event x occurring at future time t under utility function u, discounted back to the present (time 0) using discount factor β, is
In accounting, amortization is a method of obtaining the expenses incurred by an intangible asset arising from a decline in value as a result of use or the passage of time. Amortization is the acquisition cost minus the residual value of an asset, calculated in a systematic manner over an asset's useful economic life.
