Capital Output Ratio is the ratio of capital used to produce an output over a period of time. This ratio has a tendency to be high when capital is cheap as compared to other inputs. For instance, a country with abundant natural resources can use its resources in lieu of capital to boost its output; hence the resulting capital output ratio is low. The capital output ratio tends to increase if the capital available in a country is cheaper than the other inputs. Therefore, the countries that are rich in natural resources have a low capital output ratio. This is because they can easily substitute the capital with natural resources in order to increase the output. When countries use their natural resources instead of capital then COR reduces.

Correct Option: B

Per capita income or average income or income per person is the mean income within an economic aggregate, such as a country or city. It is calculated by taking a measure of all sources of income in the aggregate (such as GDP or Gross National Income) and dividing it by the total population. It does not attempt to reflect the distribution of income or wealth. Per capita income is often used to measure a country’s standard of living. However, it is not a good standard of measuring standard of living as it is income of one person of the country.

The volume of investment depend upon the following two factors: (a) rate of interest; and (b) marginal efficiency of capital. Before investing the money a businessman compares interest with the rate of marginal efficiency capital. If they expect that rate of profit will be greater than the rate of interest, then they invest the money otherwise not. The expected rate of return on capital is called the marginal efficiency of capital. In other words, marginal efficiency of capital is a return on investment which is based partly on expectations of future yields and partly on the actual price of the capital good concerned.

Say’s law, or the law of market, is an economic principle of classical economics named after the French businessman and economist Jean-Baptiste Say (1767–1832), who stated that “supply creates its own demand”. “Supply creates its own demand” is the formulation of Say’s law by John Maynard Keynes. The rejection of this doctrine is a central component of The General Theory of Employment, Interest and Money (1936) and a central tenet of Keynesian economics.

Capital formation is frequently thought of as a measure of total “investment”, in the sense of that portion of capital actually used for investment purposes and not held as savings or consumed. But in fact, in national accounts, the concept of gross capital formation refers only to the accounting value of the “additions of non-financial produced assets to the capital stock less the disposals of these assets”. “Investment” is a broader concept that includes investment in all kinds of capital assets, whether physical property or financial assets. The net valuation method views “depreciation” as the compensation for the cost of replacing fixed equipment used up or worn out, which must be deducted from the total investment volume to obtain a measure of the “real” value of investments; the depreciation write-off compensates and cancels out the loss in capital value of assets used due to wear & tear, obsolescence, etc.
