- Explain how to derive a total expenditures (TE) curve.You are given data on the following variables in an economy: Government spending 300 Planned investment 200 Net exports 50 Autonomous taxes 250 Income tax rate 0.1 Marginal propensity to consume 0.5 Use the data above to answer the following questions. Consumption (C) is 600 when income (Y) is equal to 1500. Solve for autonomousconsumption. Solve for the equilibrium level of output in the following two scenarios: there isan income tax t=0.1, there is no income tax in the economy. Denote these two variablesby and respectively. In the economy with an income tax of 10%, what is the budget balance of thegovernment? Solve…Use the information in the following table to answer the questions below.

Consumption?Q.1.14 In the Keynesian model, what is the most important determinant of ahousehold’s consumption?(a) Disposable income.(b) Total wealth.(c) The number of persons in the household.(d) Its’ net wealth. Q.1.15 Induced consumption is: (a) the part of consumption which is independent of the level of income.(b) the minimum level of consumption that is financed from sources otherthan income.(c) The maximum level of consumption that is financed from sources otherthan income.(d) shown by the slope of the consumption function.Q.1.16 In the Keynesian model, an introduction of a proportional tax will: (a) increase the slope of the consumption function.(b) reduce the multiplier.(c) increase the equilibrium level of income.(d) increase the multiplier.Q.1.17 A decrease in the price level will: (a) shift the AS curve to the left.(b) shift the AD curve to the left.(c) shift the AS curve to the right.(d) leave both the AD curve and the AS curve unchanged.Question 17 – Question 20: In this question, interest rate and prices are held fixed, and the economy can be described by the income-expenditure model. Consumption: C = 190 + 0.8YD; where YD = disposable income Investment: I = 180 – 50i, where i = 0.1 (10% & it is held fixed) Government spending: G = 183 Taxes: T = 272 Transfers: TR = 57 Exports: X = 18 Imports: IM = 24 Question 17 If the current level of output is 1975, find the levels of national savings and unplanned investment.

(Hint: Be very careful in your calculations. They are not difficult, but it is easy to make careless mistakes that produce dramatically wrong results.) (e) How much does the government collect in taxes when the economy is in equilibrium? (f) What is the government’s budget deficit or surplus?Study the diagram below and answer the question.Which one of the following statements is false? A Y1 represents the equilibrium level of income.B The curve labelled A = C + I shows the total of consumption and investment spending.C The curve labelled C shows the total of autonomous and induced consumption spending.D The point labelled D shows where savings equal investment. In macroeconomic theory, total or aggregate spending is denoted by A and total or aggregateproduction of income by Y. Which one of the following statements is incorrect? A When A is greater than Y, there is disequilibrium and Y will tend to increase.B When A is equal to Y, there is equilibrium and Y will remain unchanged.C When A is less than Y, there is disequilibrium and Y will decrease.D When A is greater than Y, there is disequilibrium and A will decrease.Assume that in 2015, the following prevails in theRepublic of Nurd:Y = $200 G = $0C = $160 T = $0S = $40I (planned) = $30Assume that households consume 80 percent of their income, they save 20 percent of their income, MPC = 0.8,and MPS = 0.2.

Why the AD line is upward sloping?Suppose the government spending falls by 100 and in this case marginal propensity to consumeis 0.8. what is the value of change in output. Draw a diagram to show the shift in AD line due tothis change in government spending and output.In the Keynesian cross model, assume that the consumption function is given byC = 110 + 0.75(Y - T). Planned investment is 300; government purchases is 350. Assume a balanced budget.a. Graph planned expenditure as a function of income.b. What is the equilibrium level of income?c. If government purchases increase to 400, what is the new equilibrium income? What is the multiplier for government purchases?d. What level of government purchases is needed to achieve an income of 2,200? (Taxes remain unchanged.)e. What level of taxes is needed to achieve an income of 2,200? (Government purchases remain at 350.). Suppose the United States economy is repre- sented by the following equations: Z = C + I + G, C = 500 + 0.75YD, T = 600, I = 300, YD = Y − T , G = 2000 Given the above variables, calculate the equilibrium level of output. assume that government spending decreases from 2000 to 1900. What is the new equilibrium level of output? How much does income change as a result of this event? What is the multiplier for this economy?
