Difference between MEC and MEI
Marginal Efficiency of Capital (MEC)
Marginal Efficiency of Capital (MEC) is the rate of discount which makes the discounted present value of expected income stream equal to the cost of capital.
MEC was first introduced by J.M Keynes in 1936. According to him, it is an important determinant of autonomous investment.
The marginal efficiency of capital is a key concept in economics that describes the relationship between the production of goods and services and the investment in capital.
The marginal efficiency of capital is used to measure the amount of output produced by an extra unit of investment. The marginal efficiency of capital is important because it helps to understand how an economy grows and how resources are allocated.
The marginal efficiency of capital (MEC) is the increase in output that results from an additional unit of investment.
MEC is determined by the productive capacity of the capital goods available for use and the expected return on investment.
The MEC declines as the amount of capital invested increases, because each successive unit of investment has a lower expected return.
The MEC plays an important role in economic decision-making, because it represents the maximum return that can be expected from an additional unit of investment.
In order to maximize economic growth, firms must invest in projects with a MEC that is greater than the cost of capital.
The MEC can also be used to compare different investment opportunities and determine which one will generate the highest return.
Marginal Efficiency of Investment (MEI)
Marginal Efficiency of Investment (MEI) is the expected rate of return on investment as additional units of investment are made under specified conditions and over a stated period.
The marginal efficiency of investment (MEI) is the extra output generated by an additional unit of investment.
The MEI is a key concept in macroeconomics and is used to measure the return on investment for a firm or economy. The higher the MEI, the more efficient an economy is at using capital.
The MEI can be calculated using data on output and investment. The formula for the MEI is: MEI = (ΔY/ΔI) x 100. The ΔY represents the change in output and the ΔI represents the change in investment.
The marginal efficiency of investment is important because it measures how well an economy is using its resources. If the MEI is high, then firms can generate more output with less investment.
The marginal efficiency of investment (MEI) is the increase in output from an additional unit of investment.
MEI is determined by the interplay of the production function and the demand for the firm’s output.
The higher the MEI, the more efficient an organization is in using its resources to generate output.
To maximize profits, firms seek to invest in projects with a high MEI.
The MEI can be used to compare different investments and choose those with the highest return.
The level of risk associated with an investment also affects the MEI.
Changes in technology and other factors can lead to changes in the MEI over time.
Understanding the concept of MEI is important for making sound investment decisions.
When the cost of borrowing is high, businesses are less motivated to borrow money and make investments in different projects because the high cost of borrowing reduces the profit margin of the business firms; business firms always cannot raise the price of their product and services to increase profit.
The concepts of the marginal efficiency of capital(MEC) and the marginal efficiency of investment (MEI) seem similar.
There are however some basic differences between MEC and MEI. Some of the basic differences between MEC and MEI are as follows:
MEC Vs MEI
Marginal Efficiency of Capital(MEC) |
Marginal Efficiency of Investment(MEI) |
| 1) MEC is based on a given supply price for capital. | 1) MEI is based on the induced change in the price due to a change in the demand for capital. |
| 2) MEC represents the rate of return on all successive units of capital without regard to existing capital. | 2) MEI shows the rate of return on just those units of capital over and above the existing capital stock. |
| 3) In MEC the capital stock is taken on the horizontal axis of the diagram. | 3) In MEI the amount of investment is taken on the horizontal axis of the diagram. |
| 4) The MEC is a “stock” concept. | 4) The MEI is a “flow” concept. |
| 5) The MEC determines the optimum capital stock in an economy at each level of the interest rate. | 5) The MEI determines the net investment of the economy at each interest rate, given the capital stock. |

People Also Ask,
Are MEC and Mei same?
MEC and Mei are two different terms that are often confused. MEC is the Marginal Efficiency of Capital, which is a measure of the return on investment for each additional unit of capital.
Mei is the Marginal Efficiency of Investment, which is a measure of the return on investment for each additional unit of investment.
There is a difference between these two terms, but they are often used interchangeably.
Factors Affecting Marginal Efficiency of Investment (MEI)
Many factors affect the marginal efficiency of investment (MEI). The MEI is the rate of return on an investment after taking into account inflation and taxes.
One of the most important factors affecting MEI is the level of interest rates. When interest rates are low, it costs less to borrow money and invest in projects with a higher MEI.
Another important factor affecting MEI is inflation. Inflation reduces the purchasing power of money, so investments must be made in assets that will increase in value faster than inflation to earn a positive real return.
Taxes can also have a significant impact on MEI, as they reduce the amount of money available to reinvest in new projects.
Other factors that can affect MEI include political stability, government regulations, and changes in technology. Political instability can make it difficult to get loans and invest in long-term projects.
Will a firm invest if its Mei is 15% and ROI is 10%?
No, a firm will not invest if its Mei is 15 and ROI is 10. The reason being is that the Mei would have to be at least 16.5 for the firm to see any return on investment. Anything below that and the firm would actually be losing money by investing.
What is the relationship between marginal efficiency of capital MEC and rate of interest?
There is a strong relationship between the marginal efficiency of capital (MEC) and the rate of interest. The MEC is the average amount of output that can be produced from an additional unit of capital.
The higher the MEC, the higher the rate of return on investment and the lower the rate of interest. The lower the MEC, the lower the rate of return on investment and the higher the rate of interest.
