Tasks

1. When income 200 den. u Household consumption expenditure 160 den. u, while income 300 den. u - 230 den. u Determine the value of savings income in the 400 den. u and the value of the threshold income.


2. The function of consumption of the population defined by the equation C = 50 + 0,75 Y. The value of personal income is 500 den. u, the income tax rate - 20%. Define:

- The amount of consumption and savings;

- The average propensity to consume and save.


3. The Government of reducing military spending by 10 billion. Rub., The marginal propensity to consume is 0.6. Determine the change in nominal GNP.


4. Determine the equilibrium value of the national income, if the amount of savings is given by S = 0,5 Y - 50, planned investments are 50. How to change this value in the growth of investment by 5 den. u?


5. The function of consumption is as follows: C = 100 + 0,9 DI, where DI - disposable income. On the basis of data in the table to calculate the value of consumer spending and savings for the corresponding values \u200b\u200bof disposable income:

Disposable income (bln. Rub.) Consumer spending (bln. Rub.) Savings (bln. Rub.)

Problem 6. Using the data of the problem 4, calculate the marginal propensity to consume (MPC) and save (MPS); calculate the cost multiplier m.


Task 7. Fill in the table, after making calculations based on the following data (bn. Rub.): Consumer spending = 200 + 0.15 disposable income; investment = 200; Export = 125; Import = 25; taxes = 200.
