Hyperbolic discounting is mathematically described as = + where g(D) is the discount factor that multiplies the value of the reward, D is the delay in the reward, and k is a parameter governing the degree of discounting (for example, the interest rate).
Therefore, the preferences at t = 1 is preserved at t = 2; thus, the exponential discount function demonstrates dynamically consistent preferences over time. For its simplicity, the exponential discounting assumption is the most commonly used in economics.

"GDP" may refer to "nominal" or "current" or "historical" GDP, to distinguish it from real GDP. Real GDP is sometimes called "constant" GDP because it is expressed in terms of constant prices.

In economics, discounted utility is the utility (desirability) of some future event, such as consuming a certain amount of a good, as perceived at the present time as opposed to at the time of its occurrence. [1]
With the European Commission according to its data bank "AMECO" (Annual Macro-Economic Data) the marginal efficiency of capital is defined as "Change in GDP at constant market prices of year T per unit of gross fixed capital formation at constant prices of year T-.5 [that is, lagged by half a year].
