In economics, the consumption function describes a relationship between consumption and disposable income. [ 1][ 2] The concept is believed to have been introduced into macroeconomics by John Maynard Keynes in 1936, who used it to develop the notion of a government spending multiplier. [ 3]
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 ). This is compared with the formula for exponential discounting:
The net present value ( NPV) or net present worth ( NPW) [ 1] is a way of measuring the value of an asset that has cashflow by adding up the present value of all the future cash flows that asset will generate. The present value of a cash flow depends on the interval of time between now and the cash flow because of the Time value of money (which ...
Fisher equation. In financial mathematics and economics, the Fisher equation expresses the relationship between nominal interest rates, real interest rates, and inflation. Named after Irving Fisher, an American economist, it can be expressed as real interest rate ≈ nominal interest rate − inflation rate. [1] [2]
Forward Discount Rate 60% 40% 30% 25% 20% Discount Factor 0.625 0.446 0.343 0.275 0.229 Discounted Cash Flow (22) (10) 3 28 42 This gives a total value of 41 for the first five years' cash flows. MedICT has chosen the perpetuity growth model to calculate the value of cash flows beyond the forecast period.
A good's price elasticity of demand ( , PED) is a measure of how sensitive the quantity demanded is to its price. When the price rises, quantity demanded falls for almost any good ( law of demand ), but it falls more for some than for others. The price elasticity gives the percentage change in quantity demanded when there is a one percent ...
Opportunity cost, as such, is an economic concept in economic theory which is used to maximise value through better decision-making. In accounting, collecting, processing, and reporting information on activities and events that occur within an organization is referred to as the accounting cycle.
In economics, an inverse demand function is the mathematical relationship that expresses price as a function of quantity demanded (it is therefore also known as a price function ). [1] Historically, the economists first expressed the price of a good as a function of demand (holding the other economic variables, like income, constant), and ...
