- According to the Keynesian cross model if the marginal propensity to consume is 2/3, cut in taxes of 120 Billion increases equilibrium income by a) 160 Billion b) 180 Billion C) 240 Billion d) 360 BillionSuppose the marginal propensity to consume in an economy is 0.9. What would be the Keynesian multiplier in this economy? (Express your answer as a whole number – no fractions or decimals)Consider the Keynesian Liquidity Constrained consumer (LCC). • (viii) What is the marginal propensity to consume out of temporary income? What does it depend on? (ix) What is the marginal propensity to consume out of permanent income? Does it depend on the same factors you mentioned in the previous question?
- In the Keynesian cross model, assume that the consumption function is given by C = 100 + 0.75(Y - T). If government spending increases by AG = 100, what is the increase in output? How does your answer change when the spending increase is financed by an equal increase in taxes?Suppose the marginal propensity to consume is 0.6. Use the Keynesian Cross model to predict the impact on equilibrium income of each of the following policies. State the direction of the change and give a formula for the size of the impact. a. an increase in government purchases of $100billion b. an increase in taxes of $100 billion c. a $100 billion increase in both government purchases and taxes?Given a simple Keynesian spending multiplier of 2, how will GDP (Y) change when business investment increases by $15 billion, exports increase by $5 billion, and government spending drops by $10 billion? Y increases by $20 billion. Y decreases by $20 billion. Y decreases by $10 billion. Y remains unchanged.

- Keynesian cross" exercises Let the economy in our numerical example be: C = 70 + 0.75Y I = 60 Y* = 520 Exercise 1: Add government spending G = 100, not financed by taxes by taxes Show that the new equilibrium income is: Y = 920 What is the government spending multiplier? Exercise 2 : Redo your work assuming that: 1. government spending (G: 100) is financed (in part) by a per capita tax 1. public spending (G: 100) is financed (partly) by a per capita tax (capitation) whose total amount is T=80 and, 2. the marginal propensity to consume is applied to disposable income Calculate the new equilibrium income (Y2) and the disposable income (Y ;) What is the multiplier for the government's balance? Exercise 3: If government spending is financed by a 10% income tax and the propensity to consume is applied to disposable income, calculate the equilibrium income (Y2*) (Y2*) and disposable income (Y;) In this case, what is the government's balance of payments multiplier?In a Keynesian model, why would a $100 million increase in government expenditure on goodsand services have a greater impact on aggregate demand than a $100 million reduction in taxrevenue?A Consumers spend only part of any extra disposable income.B Government expenditure does not create wealth.C The marginal tax rate affects the value of the multiplier.D The multiplier does not apply to consumer expenditure.Question 1Explain fully how the equilibrium output, income, and employment are determined in the Keynesian model. Illustrate with an appropriate graph. Suppose that the equilibrium GDP is $500 billion and the full employment GDP is $600 billion. If the slope of the AE curve is 0.8, how much would the government have to change its expenditure to get the economy to full employment equilibrium? Illustrate your answer with an appropriate graph, and show the numerical values in your graph. Explain your understanding of the multiplier process used in answering part B.
