The marginal efficiency of capital (MEC) is that rate of discount which would equate the price of a fixed capital asset with its present discounted value of expected income.
The term “marginal efficiency of capital” was introduced by John Maynard Keynes in his General Theory, and defined as “the rate of discount which would make the present value of the series of annuities given by the returns expected from the capital asset during its life just equal its supply price”.
The MEC is the net rate of return that is expected from the purchase of additional capital. It is calculated as the profit that a firm is expected to earn considering the cost of inputs and the depreciation of capital. It is influenced by expectations about future input costs and demand. The MEC and capital outlays are the elements that a firm takes into account when deciding about an investment project.
The MEC needs to be higher than the rate of interest, r, for investment to take place. This is because the present value PV of future returns to capital needs to be higher than the cost of capital, Ck. These variables can be expressed as follows:
PV = Rn / (1 + r)n, where n is the number of years considered and Rnis the net return per yearCk = Rn / (1 + MEC)n, where Ck is the capital outlays.
Hence, for investment to take place, the following condition is necessary: PV > Ck, that is MEC > r. As a consequence, an inverse relationship between the rate of interest and investment is found (i.e.: a higher rate of interest generates fewer investment).
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].
