BÀI TẬP PHẦN DI, C, S, MPC, MPS

TRUE/FALSE:

1. Consumption equals disposable plus saving.

2. the most significant determinant of the level of consumer spending is diposable income.

3. Consumption rises and saving falls when disposable income increase.

4. the break even income is the income level at which business begins to make a profit.

5. The average propensity to save is equal to the level of saving divided by the level of consumption.

6. The marginal propensity to consume is the change in consumption divided by the change in income.

7. The slope of the saving schedule is equal to the average propensity to save.

8. An increase in wealth will increase the consumption schedule ( shift the consumption curve upward)

9. The real interest rate is the nominal interest rate minus the rate of inflation.

10. An increase in the stock of capital goods on hand will decrease the investment demand.

11. An increase in planned inventories will decrease the investment demand.

12. investment tends to be relatively stable over time.

13. The multiplier is equal to the change in real GDP multiplied by the intial change in spending.

14. The multiplier effect works only in a positive direction in changing GDP.

15. The higher the marginal propensity to consume , the larger the size of the multiplier.
