- Consider an aggregate consumption function in a simple macro model with government and taxes. Given a marginal propensity to consume out of disposable income of 0.77and a net tax rate of 12 percent of national income, the marginal propensity to consume out of national income is ________.Suppose the consumption function is C = $700 billion + 0.8Y and the government wants to stimulate the economy. What will the cumulative AD shift (after multiplier effects) be for d. the increased government spending? $ __ billion e. the tax cut? $ __billion f. the increased transfers? $ __billionConsider the Aggregate expenditure model. Where:AD = C + I + G + NX (1)where I, G, and NX are all autonomous.C = C + c∗(Y + T R − T A)(2)where T A = tY with t ∈ [0, 1] is the proportional tax rate and c∗ ∈ (0, 1) is themarginal propensity to consume.a. Using the information above, solve for AD. Combineall the autonomous terms into one term, A. b. In an (x, y) plane, where Y is on the horizontal axis and AD is on thevertical axis, illustrate the AD curve you derived above along with the 450line.Make sure to explain how you got the Y-intercept and solve for the slope c. Provide an economic interpretation for the slope of the AD function. d. Solve for the equilibrium level of output and show what happens to outputwhen G increases by 1 unit. That is, what is ∆Y ? Show your result graphicallyand explain how the AD curves shifts and by how much. Briefly explain.
- Assume that a hypothetical economy with an MPC of 0.8 is experiencing severe recession. Instructions: In part a, round your answers to 2 decimal places. Enter your answers as positive numbers. In part b, enter your answers as whole numbers. a. By how much would government spending have to rise to shift the aggregate demand curve rightward by $30 billion? How large a tax cut would be needed to achieve the same increase in aggregate demand? b. Determine one possible combination of government spending increases and tax increases that would accomplish the same goal without changing the amount of outstanding debt (i.e., maintaining the budget balance at its current value).In an economy with no government and no foreign sectors, autonomous consumer spending is $250 billion, planned investment spending is $350 billion, and the marginal propensity to consume is 2/3. a) Plot the aggregate consumption function and planned aggregate spending. b) What is unplanned inventory investment when real GDP equal $600 billion? c) What is Y*, income-expenditure equilibrium GDP? d) What is the value of the multiplier? e) If planned investment spending rises to $450 billion, what will be the new Y*?Suppose that the marginal propensity to consume is dC/dy= 0.4 + (1 / sq. root of 3y + 10)(in billions of dollars) and that consumption is $9 billion when disposable income is $0. Find the nationalconsumption function C. Round numbers in your answer to two decimal places when appropriate.
- 9 In the simple macro model with government and foreign trade, if the marginal propensity to consume out of disposable income is MPC, and the net tax rate is t, and the marginal propensity to import is m, then what will be the marginal propensity to consume out of national income? What will be the simple multiplier? Please show your stepsSuppose that when government lowers corporate taxes this results in an increase in business investment of $280 billion. Further assume that MPC = 0.93. Calculate the value of MPS: Calculate the value of the multiplier: Compute the first three rounds of multiplier effects and cumulative effect on AD: Cumulative effect on AD: 1st cycle: 2nd cycle: 3rd cycle: Compute the total cumulative impact on AD after an infinite number of cycles (the "nth" cycle):True or false? Why?"A temporary tax rise never has a significant effect on current consumption."
