Marginal Rate of Investment (MEI) # Subject Matter: The expected profit from an investment, as percent of the investment, measures the rate of return on the investment. Economists call the expected rate of return on an addition to capital investment as the marginal efficiency of investment (MEI). For example, if spending increases from £80,000 to £100,000, and forecasting tools predict that revenue would increase from £200,000 to £230,000, the marginal ROI of that £20,000 is 1.5 (£30,000 divided by £20,000) Marginal ROI can deliver insights to guide your spend across your digital programs. If the marginal revenue product of the fifth worker hired by a firm is $15 and the price of a unit of output is $5 regardless of how much is sold, then the marginal product of the fifth worker is A) 15 units of output If there are no other changes, then if the second kilogram of seeds applied to land produces only half the output of the first (showing diminishing returns), the marginal cost would equal $1 per half ton of output, or $2 per ton, and the average cost is $2 per 3/2 tons of output, or $4/3 per ton of output.

MROI in context of a “hurdle rate” – the minimum return the company Similarly, indifference curvesindifference curve A curve of the points which indicate the combinations of goods that provide a given level of utility to the individual. It is only when the return is greater than cost, investment is made. is known as the investment demand function or the marginal efficiency of capital curve.
The marginal rate of return measures the effectiveness of investing extra time and effort. For example, suppose a company spends $150,000 on marketing, then increases the budget by $1,000. The marginal rate return is the amount of increased sales that added $1,000 generates. Determine the marginal return on an investment which is $1,000 less in profit. The calculation is $4,000 divided by $10,000 -- 40 percent. This further illustrates that a $1,000 change in profit is equivalent to a 10 percent change in ROI. Marginal efficiency of investment, in economics, expected rates of return on investment as additional units of investment are made under specified conditions and over a stated period of time. A comparison of these rates with the going rate of interest may be used to indicate the profitability of investment. A firm's marginal rate of return on investment curve shows the amount: a. Saved by the firm at each alternative interest rate b. Invested by the firm at each alternative interest rate c. Saved by the firm at each alternative rate of time preference d. Invested by the firm at each alternative marginal product of investment e. Marginal rate of return is not only applicable to business decisions; it's also a valuable tool in any individual's decision-making process.
