#3 . Assume an economy with 1000 consumers. Each consumer has income in the current period of 50 units and future income of 60 units, and pays a lump-sum tax of 10 in the current period and 20 in the future period. The market real interest rate is 8%. Of the 1000 consumers, 500 consume 60 units in the future, while 500 consume 20 units in the future. (a) Determine each consumer’s current consumption and current saving. (b) Determine aggregate private saving, aggregate consumption in each period, government spending in the current and future periods, the current-period government deficit, and the quantity of debt issued by the government in the current period.
Suppose, the government of Australia incurs a budget deficit of $50 billion due to increased government spending in 2020 as result of Covid 19. Because of this, the government borrowing in 2021 increases by the same amount. a) Compare the size of equilibrium changes in 1) investment, 2) public saving, 3) private saving and 4) national saving (public saving + private saving) with $50 billion increase in borrowing. Compare the changes (increase/decrease) in these variables indicating same, less or more than the $50 billion. b) Will the equilibrium quantity of national savings change by more or less than the initial change in public saving? Explain your answer
2- Given: C = 102 + 0.7Y , J = 150 - 100 M_{S} = 300, M_{t} = 0.25Y and M_{s} = 124 - 200 ,. Find: a- The equilibrium level of income and the equilibrium rate of interest, b- The level of C. I, Mr and M_{z} when the economy is equilibrium
Assume that the economy can be modeled as follows: AE = C + I + G C = 300 + .6Yd I = 400 G = 100 T = 200 y= 1700 consumption = 1200 4) What is the level of private saving in equilibrium? 5) What is the level of public saving in equilibrium? 6) What is the level of aggregate saving in equilibrium? 7) Imagine the government would like to increase equilibrium GDP to 2,000, what would it have to set the level of government spending to? 8) What is the size of the spending multiplier? 9) What is the size of the tax multiplier?
2. The government decreases current taxes, while holding government spending in the present and the future constant. (a) Using diagrams, determine the equilibrium effects on consumption, investment, the real interest rate, aggregate output, employment, and the real wage. What is the multiplier, and how does it differ from the government expenditure multiplier? (b) Now suppose that there are credit market imperfections in the market for consumer credit, for example due to asymmetric information in the credit market. Repeat part (a) and explain any differences in your answers in parts (a) and (b). Note:- Do not provide handwritten solution. Maintain accuracy and quality in your answer. Take care of plagiarism. Answer completely. You will get up vote for sure.

3. Explain how a consumption tax could lead to a decrease in real interest rates.
Suppose the government borrows $20 billion more next year than this year. a. Use a supply-and-demand diagram to analyse this policy. Does the interest rate rise or fall? b. What happens to investment? To private saving? To public saving? To national saving? Compare the size of the changes to the $20 billion of extra government borrowing. c. Suppose households believe that greater government borrowing today implies higher taxes to pay off the government debt in the future. What does this belief do to private saving and the supply of loanable funds today? Does it increase or decrease the effects that you discussed in parts (a) and (b)?
Suppose that the government provides tax cuts for those who invest in new capital. Illustrate and explain how this increase in government spending affects investment and the real interest rate in equilibrium. Show a graph and explanation.
5 3. permanent Income Hypothesis a) suppose that beta=.9 and R= 2222 (that is ~22%). For an individual who acts according to the PIH, will their consumption next period be higher than current consumption or lower? b) What is the main crucial difference between the Keynesian Consumption function and the consumption function derived from the PIH (or Lifetime Income Hypothesis)? c) If Present Value of future income stream is 500,000 and a person has a beta of.8, how much will their consumption go up today if only today's income increases by 1000? How much will their consumption increase (approximately) if their income goes up by 1000 in all periods?
1) Following is information for the economy of Donut. All units are million dollars. Their autonomous consumption is $500, and the marginal propensity to consume is 0.6. Investment spending is constant at $300, and government expenditure is constant at $200. Exports are constant at $100 and imports are constant at $230. Net taxes are constant at $100. Calculate and state your answers for the following questions. A.. What is the value of private saving in this economy when the real GDP is $500? B..What is the value of autonomous aggregate expenditure i.e. AE0? C..What is the size of the multiplier in this economy? D... What is the value of aggregate planned expenditure when real GDP is $1000?
