Need some help with the following questions, thanks!

Consider a hypothetical closed economy in which households spend $0.80 of each additional dollar they earn and save the remaining $0.20. The marginal propensity to consume (MPC) for this economy is V , and the spending multiplier for this economy is V . Suppose the government in this economy decides to decrease government purchases by $300 billion. The decrease in government purchases will lead to a decrease in income, generating an initial change in consumption equal to V . This decreases income yet again, causing a second change in consumption equal to V . The total change in demand resulting from the initial change in government spending is v The following graph shows the aggregate demand curve (ADl) for this economy before the change in government spending. Use the green iine (triangie symboi) to piot the new aggregate demand curve {A32} after the spending muftipiier effect takes piece. Hint: Be sure that the new aggregate demand curve {11.02) is parallel to the initial aggregate demand curve {AD1). You can see the slope of AD1 by selecting it on the graph. 140 135 AD 1310 125 120 115 PRICE LEVEL (CPI) 11B 105 100 (I 1 2 3 4 5 6 i 8 REAL GDP (Trillions of dollars) Suppose the economy had been producing at potential output but is now experiencing a recession. Which of the following are discretionary fiscal policies that could bring the economy closer to potential output? Check all that apply. O A reduction in spending on education A tax increase Additional spending on national park facilities O A tax cut In the preceding scenario, is the discretionary fiscal policy needed to bring the economy closer to potential output an example of expansionary fiscal policy or contractionary fiscal policy? O Contractionary O ExpansionaryThe following graph shows aggregate demand (AD) and aggregate supply (AS) curves for a hypothetical economy.

In order to move the economy to fullemployment output at the lowest possible price level, the aggregate demand curve must shift to the V by V at each price level. Use the green line (triangle symbols) to show the shift in aggregate demand necessary to return the economy to full employment. Then use the purple drop lines (diamond symbol) to show the macroeconomic equilibrium at fullemployment output. Be sure the new aggregate demand curve (ADg) is parallel to A01. You can click on A01 to see its slope. Suppose the government in this economy wants to enact scal policies that will shift the aggregate demand curve in the direction and magnitude you indicated. The marginal propensity to consume (MPG) in this economy is 0.8. This implies a spending multiplier of V and a tax multiplier of V . Consider each fiscal policy listed here. which policies would shift the aggregate demand curve in a way that restores fullemployment output at the lowest possible price level? Check all that apply. [3 Increase government expenditures by $20 billion and raise taxes by $10 billion [3 Increase government expenditures by $60 billion and raise taxes by $60 billion [3 Reduce government expenditures by $12 billion [3 Decrease taxes by $20 billion and decrease government expenditures by $8 billion [3 Cut taxes by $15 billion
