The investment function is I = 200-25r. G =100 T=100 1. What is the IS equation 2. Suppose that the government purchases (G) raised from 100 to 150. How much does the IS Curve shift? What are the new equilibrium interest r and level of income, y? If there is no crowding out effect, what is the full multiplier effect of the change in G?If the Marginal Propensity to Consume (MPC) is .90, estimate the total (multiplied) effect of government purchases/spending of $100B in the economy in terms of its aggregate expenditure (Hint: Multiplier = 1 / 1 – MPC). Calculate the net cumulative change in aggregate expenditure if taxes were cut by $200 billion and MPC is estimated to be .75. What if government expenditure was increased by $200 billion? (Hint: Total change in expenditure = multiplier x new expenditure or spending injection)
- Suppose there is some hypothetical closed economy in which households spend $0.85 of each additional dollar they earn and save the remaining $0.15. The marginal propensity to consume (MPC) for this economy is____ , and the spending multiplier for this economy is ____. Suppose the government in this economy decides to decrease government purchases by $300 billion. The decrease in government spending will lead to a decrease in income, creating an initial change in consumption equal to _____ . This decreases income yet again, leading to a second change in consumption equal to ____ . The total change in demand resulting from the initial change in government spending 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? $ __billionWhich one of the following statements relating to marginal propensity to consume is INCORRECT? (a) Marginal propensity to consume for a given consumption function is usually less than 1; (b) If the people in a country save 30c out of every rand they earn, the marginal propensity to consume in this country is said to be 0.7; (c) If the marginal propensity to consume is given as 0.622, then the value of the simple multiplier will be 2.5; (d) The larger the value of the marginal propensity to consume, the steeper the consumption function will be.
- Suppose that autonomous consumption (a) is 300, private investment spending (I) is 420,government spending (G) is 400 , Net taxes (T) are 400 and marginal propensity to consume(b) is 80 %, and marginal tax rate (t) is 25 % . By using the above information: b) Suppose that the potential income level is 2500 in the economy. In this case, what kind offiscal policy you can use to reach the full employment level. (show this numerically andexplain it on your graph)Suppose the consumption function is $800 billion +0.8y and the government wants to stimulate the economy. By how much will aggregate demand at current prices shift initially (before multiplier effects) with: a. A $50 billion increase in government purchases b. A $50 billion tax cut c. A $50 increase from income transfers what will the cumulative ad shift be for: d. The increased government spending e. The tat cut f. The increased transfersSuppose there is some hypothetical closed economy in which households spend $0.75 of each additional dollar they earn and save the remaining $0.25. The marginal propensity to consume (MPC) for this economy is _____ , and the spending multiplier for this economy is _____ Suppose the government in this economy decides to decrease government purchases by $250 billion. The decrease in government spending will lead to a decrease in income, creating an initial change in consumption equal to $______ billion. This decreases income yet again, leading to a second change in consumption equal to $________ billion . The total change in demand resulting from the initial change in government spending is $ ________ trillion. The following graph shows the aggregate demand curve (AD1AD1) for this economy before the change in government spending.

- An economy has the following consumption function: C=$200+0.8DI . The government budget is balanced, with government purchases and taxes both fixed at $1,000. Net exports are $100. Investment is $600. 1. The value of equilibrium in this model is . 2. If government spending increases by $150, the equilibrium value increases by , demonstrating a multiplier value of . 3. If both G and T rise by $150 at the same time, the equilibrium Y will increase byConsider a hypothetical closed economy in which households spend $0.70 of each additional dollar they earn and save the remaining $0.30. The marginal propensity to consume (MPC) for this economy is0.7 , and the oversimplified multiplier for this economy is3.3333 . Suppose the government in this economy decides to increase government purchases by $300 billion. The increase in government purchases will lead to an increase in income, generating an initial change in consumption equal to$210 billion . This increases income yet again, causing a second change in consumption equal to$147 billion . The total change in demand resulting from the initial change in government spending is$1 trillion . The following graph shows the aggregate demand curve (AD1 ) for this economy before the change in government spending. Use the green line (triangle symbol) to plot the new aggregate demand curve (AD2 ) after the multiplier effect takes place. For simplicity,…Suppose the following data for an economy; a consumption function of C = 800 + 0.8Yd, Investment spending is fixed at 300, Government purchases are 400, and net taxes are 100. A.) What is the MPC, MPS, and the value of the tax multiplier? B.) Suppose government increases taxes by 100, use the corresponding multiplier to calculate the new equilibrium level of income. C.) Check to ensure that the multiplier worked (confirm algebraically that your answer in B is correct, that is, solve for the new equilibrium level of income (Y)).
