Short Answer TypeExplain how 'distribution of gross domestic product' is a limitation in taking gross domestic product as an index of welfare.
Given that national income is Rs.80 crore and consumption expenditure Rs.64 crore, find out average propensity to save. When income rises to Rs.100 crore and consumption expenditure to Rs.78 crore, what will be the average propensity to consume and the marginal propensity to consume?
Explain the relationship between investment multiplier and marginal propensity to consume.
Investment multiplier implies that any change in the investment leads to a corresponding change in the income and output by multiple times. That is, in other words, the change in the income and output is more than (or multiple times of) the change in investment.
Investment Multiplier, K = △Y/△I
Investment Multiplier shares a direct positive relationship with marginal propensity to consume. That is, higher the value of MPC, higher will be the value of investment multiplier and vive-versa. That is Higher the proportion of increased income spend on consumption, higher will be value of investment multiplier.
Algebraically, the relationship is expressed as follows.
K= 1/(1- MPC)
