The marginal efficiency of capital (MEC) is a concept in economics that refers to the expected rate of return on an additional unit of capital invested in a project. It is an important factor in the decision-making process of businesses and investors, as it helps them determine the profitability of potential investments.

The MEC is calculated by dividing the expected return on an investment by the cost of the capital used to make the investment. For example, if a business expects to earn a return of $100 on a capital investment of $1000, the MEC would be 10%. This means that for every $1 of capital invested, the business expects to earn a return of 10 cents.

The MEC is influenced by a number of factors, including the riskiness of the investment, the level of competition in the market, and the cost of capital. A higher MEC indicates a more profitable investment, while a lower MEC suggests a less profitable or potentially unprofitable investment.

Businesses and investors use the MEC to compare the expected returns of different investment opportunities and decide which ones to pursue. For example, if a business has the choice between two investment opportunities with MECs of 10% and 20%, it would likely choose the one with the higher MEC because it is expected to be more profitable.

The MEC is an important concept in the field of finance, as it helps businesses and investors make informed decisions about where to allocate their capital. By understanding the MEC, businesses and investors can make more informed choices about which investments are likely to be the most profitable, helping to increase their overall financial success.

## Marginal Efficiency of Capital (MEC) and Investment Demand Function

Definição: O desempenho marginal do capital é a taxa única de desconto que pode tornar o valor atual do benefício líquido esperado de um ativo de capital igual ao preço de fornecimento quando o preço de fornecimento não aumenta. For it now seems clear that the disquisitions of the schoolmen were directed towards the elucidation of a formula which should allow the schedule of marginal efficiency of capital to be high, whilst using rule and custom and the moral law to keep down the rate of interest. To calculate the MEC, first I assume an interest rate. Pengertian MEI ini sebenarnya berkaitan dengan permintaan barang-barang kapital bagi suatu perusahaan, dengan anggapan bahwa penerimaan aliran kas dari proyek investasi tersedia dan diketahui secara pasti oleh perusahaan. Example - How to use Marginal Efficiency Of Capital is an example of a term used in the field of economics Economics -. Marginal Efficiencies of Capital Once we correct for the changing cost of startup, the net present value and marginal efficiency criteria will give the same ordering—Project 2 is preferred if the interest rate is less than 28. MEI schedule labeled MEIa shows that at point F, when the rate of interest is 9%, the net investment is zero.

NPV Profile The NPV profile has three properties. MARGINAL EFFICIENCY OF CAPITAL John Maynard Keynes advocates the rate of return approach to economic calculation. Any event that is likely to happen in future is taken into account discounted in the present prices of securities. On the other hand, when the prices of old stocks on the stock exchange are low, it will be more profitable to purchase claim on the existing assets than to build new ones; because in these circumstances, the MEC of capital is likely to be lower than the current rate of interest and, therefore, there may be no inducement to invest. Hence, total social investment, as well as total financial investment remains unaffected as a result of stock exchange transactions. But the position is serious when enterprise becomes the bubble on a whirlpool of speculation. Prior to his general theory, an explanation of the lower and upper turning points was perhaps the most difficult task of the trade cycle analysis.

As a consequence, an inverse relationship between the rate of interest and investment is found i. Keynes never enunciated an exclusive trade cycle theory. To demonstrate, Figure 3 combines the NPV diagram and the loanable funds diagram. Marginal Efficiency of Capital The marginal efficiency of capital of the wooden bridge is 23.

As shown in Part A, this increase of 30 billion dollars reduces the MEC about 8 per cent actually 7. ADVERTISEMENTS: Keynes provided the explanation of the turning points by introducing the concept of consumption function, which indicates that the marginal propensity to consume being less than unity, the expenditure on consumption goods does not increase in proportion to the increase in income. It should be noted that the stagnation thesis enunciated above applies only to industrially advanced capitalist economies and not to the underdeveloped countries of Asia and Africa. The steel bridge generates the same size cash flows as the wooden bridge, but the steel bridge has a longer period of production and a longer life than the wooden bridge. With rise in prices, prospective yield increases and with the fall in prices, it decreases. Further, Keynesian analysis of the investment function is related to the rate of interest and the marginal efficiency of capital because he assumed that wages equal the marginal productivity of labour. If there is an improvement in technology, it can make investment more worthwhile.

An Example: ADVERTISEMENTS: For a numerical illustration, assume that the purchase price of a capital good is Rs. But I now read these discussions as an honest intellectual effort to keep separate what the classical theory has inextricably confused together, namely, the rate of interest and the marginal efficiency of capital. Collapse of MEC The marginal efficiency of capital collapses from 23. In the rate of return approach investors use the marginal efficiency of capital MEC to rank investment projects. Since the interest rate is the universal NPV input, the artificially low interest rate causes a universal falsification of NPV rankings in favor of longer, more interest rate sensitive projects. However, in a In a liquidity trap, business confidence may be very low.

The increase in the money supply pushes the interest rate below the crossover rate, but MEC rankings still favor the short-term project. Table 5 shows that the wooden bridge 23. ADVERTISEMENTS: Read this article to learn about the Marginal Efficiency of Capital MEC at business expectations. The fall in saving means consumption rises, so the wedge between saving and investment depicted in the loanable funds market causes the economy to produce at a level outside the production-possibilities frontier PPF. New York: The Macmillan Company. ADVERTISEMENTS: Moreover, with an increase in investment in capital goods, the demand for factors of production in the capital goods industries and, in view of scarcity of such factors, their prices may rise; this will also add to the cost of production. At the lower interest rate the wooden bridge has a higher ranking according to the MEC criterion, but the steel bridge has a higher ranking according to the NPV criterion.

## General Schedule of Marginal Efficiency of Capital (MEC)

A second difficulty is that Keynes has constructed a concept of marginal efficiency of capital as a whole. Loanable Funds and NPV Diagram Now suppose there is a change in consumer preferences so that consumers save more and consume less. Nevertheless, he made a significant contribution to it. What we want to find out here is the rate of discount that will make the present value of the income steam produced by a machine, say, just equal to its cost. The diagram shows that with the change in the marginal efficiency of capital, the investment demand curve shifts upward or downwards although the rate of interest remained unchanged. Since the marginal efficiency of capital is the discount rate that makes the net present value equal zero, the marginal efficiency of capital is the point at which the NPV profile intersects the y-axis.

If interest rates, were 3%, then firms would need an expected rate of return of at least 3% from their investment to justify the investment. Does that suggest the rank ordering will be different for the two projects? Future trade expectations If any business venture has good future prospect towards profitability, it encourages investment in those business sectors that yield higher rates of return in the future. Demand for goods and services Increase in demand for goods and services increase the profitability of the companies, and in return, increase the profitability of capital investments. This being an objective fact, it in turn induces a wave of pessimistic expectations a psychological factor. In the absence of fiscal policy, a variable rate of interest may be useful as a means to stabilise the cycle.

When the interest rate changes by a given amount, the percentage change in the net present value of the steel bridge is greater than the percentage change in the net present value of the wooden bridge. Now, by comparing this MEC with the current market rate of interest, r, we can at once assess whether a new investment project will be profitable or not. In short, investment is greater than savings. ADVERTISEMENTS: The import of improved technology or change in the techniques of production, discovery of new and more productive natural resources on the behaviour of the MEC has not been considered. With MEC now at 8 per cent, the new MEI schedule, relating investment expenditures to the interest rate, must show zero net investment at an interest rate of 8 per cent point K. Both these factors will combine to depress the marginal efficiency of capital. Given that the prices of capital goods rise with their rate of output as soon as net investment reaches the rate of 20 billion dollars per time period, the rise in prices of capital goods reduces the MEI from 8 to 6 per cent, or the equality with r.
