- Consider the following functions for consumption and investment: C = 1,000 + (2/3)*(Y – T) and I = 1,200 – 100*r. Furthermore, Y = 8,000, G = 2500, T = 2,000. Compute private, public, and national savings for this economy, and find the equilibrium real interest rate (r). Assume that G declines by 500 units. How will it change your answers in part (a)? What happens to the national savings, given everything else, if the public decides to consume less out of their disposable income (assume that the propensity of consume falls by 10 percent)? Given your answer in part (c), what happens to investment and real interest rate? Answer all four.1. Show that equilibruim level of income is at a point where consumption plus investment schedules intersect the 45 degree line. 2. Suppose the level of autonomous investment in an economy is K200,000 and the consumption function is given below as c = 80+0.8Y, what will be the equilibrium level of income. 4.if MPcC is 0.8, what will be the increase in the level of income if investment is increased to K400,000. 5. What increase in investment is needed to raise the income by K4000, if MPC is 0.75? How much will be the increase in consumption and saving due to this increase in income. 3. Given the consumption level C= 50 + 75Y, if we assume autonomous investment is K200,000 at what level of income will savings become equal to investment?9. Suppose Amal calculates her permanent income by adaptive expectations . Year 2020 Amal's permanent income was 38,000 , and year 2021 actual income is 41,000 . Assume that , long - run marginal to consume is 0.90 and short - run marginal propensity to consume is 0.28 . What is her consumption expenditure year 2021 ?

- a) Draw a consumption function and label the axes.b) Suppose that your friend has a consumption function of the form y=1.4x+200. Is this function sustainable in the long run? Why or why not?c) Suppose that your consumption function is y=0.75+1000. What is your marginal propensity to consume? What is your autonomous expenditure?d) State the permanent income hypothesis.e) Suppose that I raise your income today by $10, and lower it tomorrow by $10. How would your behavior change according to the consumption function (aka Keynesian, aka rule-of-thumb) model? And what about according to the permanent income hypothesis model?Assume in a simple economy that the level of saving is –500 whenaggregate output equals zero and that the marginal propensity tosave is 0.2. Derive the saving function and the consumption func-tion, and draw a graph showing these functions. At what level ofaggregate output does the consumption curve cross the 45° line?Explain your answer and show this on the graph.Find the equilibrium level of GDP (income or V) demanded in an economy in which investment (1) is always $300, net exports (X-IM) are always - 550, government expenditures (G) and taxes (T) are each equal to $400, and the consumption function is described by the following algebraic equation: C = 150 + 0.75Dl DI is disposable income. How much saving (5) is there at the equilibrium level of income. Hint: (1) Dl = Y (national income or GDP) minus taxes (Y-T) (2) Income (Y) not consumed (C) must be saved (S). This means that S = Y-C. (3) to answer this you have to set Y=AE or Y=C+1+G (X-IM), and solve for Y. Then you have to solve for S.
- (a) Suppose in a simple Keynesian economy, planned consumption function is given by C=250+0.65(Y-T).

Next, assume that some factors changes, such that the expected rate of return, declines by  two percentage points at each prospective level of investment. Assuming no change in the real interest rate, by how much and in what direction will the investment change?  which of the following might cause this change: (a) a decision to increase inventories; (b) an increase in excess production capacity.Suppose in a simple Keynesian economy, planned consumption function is given by C=250+0.65(Y-T). Planned investment, government purchases, taxes are $100 million, $100 million and $150 million respectively. What is MPC, MPS and autonomous consumption Derive the saving function. What is the equilibrium level of income? Y= AD=C+I+G If government purchases increase to $150 million, what is the new equilibrium level of income?

Now find out the multiplier value What is the amount of shift in AD curve? [Use the multiplier value from (5)]
