NCERT TEXTBOOK QUESTIONS SOLVED
1. What is Aggregate demand in Macroeconomics? [CBSE 2005C, 06, 09C, 10; AI 2015]Ans. It is aggregate expenditure on ex-ante (planned) consumption and ex-ante (planned) investment that all sectors of the economy are willing to incur at each income level.
2. What is Aggregate Supply in Macroeconomics?[CBSE 2015, 1995C, 2000; AI 1999]Ans. Aggregate supply is the total amount of money value of goods and services, (which is paid to the factor of production against their factor services) that all the producers are willing to supply in an economy
3. What is consumption function?[CBSE 2008]Ans. Consumption function expresses functional relationship between aggregate consumption and national income.
4. Can the value of APC be less than zero?Ans. No, because even at the zero level of income, we will consume something i.e., autonomous consumption.
Ans. It is so because Keynes' psychological law of consumption states that when income increases, consumption also increases but at a lesser rate. So, increase in consumption is always less than increase in income, i.e., MPC=ΔC/ΔY is always less than one.
6. Can the value of average propensity to save be negative? If yes,when?[CBSE Foreign 2009]Ans. Yes, the value of average propensity to save can be negative when consumption is more than national income, i.e., before the break-even point.
7. What can be the maximum value of marginal propensity to save?Ans. The maximum value of marginal propensity to save is 1. It is only possible when MPC = 0, i.e., the entire additional income is saved.
8. What is the relationship between APC and APS?Ans. The sum of APC and APS is equal to one, i.e., APC + APS = 1.
9. What is the relationship between marginal propensity to save and marginal propensity to consume?[CBSE Sample Paper 2010]Ans. The sum total of MPC and MPS is equal to one, i.e., MPC + MPS = 1.
10. 10. Give the meaning of autonomous consumption. [CBSE 2009]Ans. It refers to minimum level of consumption (i.e., C) , which is needed for survival, i.e., consumption at zero level of national income.
