The principle of the multiplier states that: any increase in aggregate spending that causes the aggregate demand curve to shift will result in a larger increase in national income. in the long run, the aggregate demand curve becomes relatively flat as the economy approaches full employment. any increase in national income will result in a larger increase in aggregate spending. for any given increase in income, there will be a less than proportional increase in consumer spending.

In the economy of Keynesian Island, autonomous consumption expenditure is $50 million, and the marginal propensity to consume is 0.8. Investment is $160 million, government expenditure is $190 million, and net taxes are $250 million. Investment, government purchases, and taxes are constant—they do not vary with income. The island does not trade with the rest of the world. If the government increases its purchases by $200 million, what will be the change in the economy's equilibrium real GDP? Show the change on the graph as well.
Consider an economy described by the following equations: C = 300 + 0.90 (Y – T) (Consumption) I = $200 (Investment) G = $300 (Government spending) T = $200 (Taxes) Determine the equilibrium level of national income. Suppose government spending increases to $400. What is the new level of income? What is the government spending multiplier? Suppose taxes increase to $300. What is the new level of income? What is the government tax multiplier? Based on your answers to (b) and (c), does the balanced budget multiplier theorem hold?
Changes in taxes The following graph plots an aggregate demand curve. Using the graph, shift the aggregate demand curve to depict the impact that a tax cut has on the economy. Suppose the governments of two very similar economies, economy B and economy A, implement a permanent tax cut of equal size. The marginal propensity to consume (MPC) in economy B is 0.7 and the MPC in economy A is 0.85. The economies are otherwise completely identical. The tax cut will have a larger impact on aggregate demand in the economy with the (SMALLER MPC or LARGER MPC).
Suppose you are given the following information. Autonomous spending is at $3000, government spending is at $4000, investment spending is at $2000, net exports are $1000, taxes are set at $3000 and the mpc is .8 or 80%. What is the equilibrium level of output? What would happen if the government tried to balance the budget? The other day, it was announced the consumer confidence was up last month. This sounded good news bells for firms. Why? What would be affected in our equation above? Why would it matter? Suppose the government tried to balance the budget my cutting spending, what would be the equilibrium level of output? If there is “crowding out (or in)”, what else might change in your equation? What impact would that have
Suppose that the consumer’s consumption demand function is given by Cd = 0.8(Y−T)+10. Investment is Id = 20, government expenditure is G = 10, and tax is T = 10. What is the equilibrium GDP (income)? Suppose that government expenditure increases by 10 units while tax is unchanged. How will GDP change? What is the multiplier? Suppose that government expenditure increases by 10 units while tax also increases by 10 units. How will GDP change? What is the multiplier?
Consider two closed economies that are identical except for their marginal propensity to consume (MPC). Each economy is currently in equilibrium with real GDP and total expenditure equal to $100 billion, as shown by the black points on the following two graphs. Neither economy has taxes that change with income. The grey lines show the 45-degree line on each graph. The first economy's MPC is 0.5. Therefore, its initial total expenditure line has a slope of 0.5 and passes through the point (100, 100). The second economy's MPC is 0.70. Therefore, its initial total expenditure line has a slope of 0.70 and passes through the point (100, 100). Now, suppose there is an increase of $30 billion in investment in each economy.

Use the following information on economy X to answer the questions below. Consumption function: C = 250 + 0.8Y Investment spending: I = 150 Government spending: G = 500 Exports of goods and services: X = 200 Imports of goods and services: Z = 150 Proportional tax rate: t =25% Full employment level of income = 3575 a) Calculate total autonomus spending for economy X. b) Calculate the multiplier for economy X. c) Calculate the equilibrium income for the economy. d) Calculate the change in government spending required to reach full employment level of income.
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: a)Find the equilibrium value of national income and show it on a graph b) Suppose that the potential income level is 2500 in the economy. In this case, what kind of fiscal policy you can use to reach the full employment level. (show this numerically and explain it on your graph)
If the MPC in an economy is .8, the increase in real GDP can occur (aggregate demand curve can shift rightward) by $100 billion by doing which of the following: Group of answer choices increasing government spending by $80 billion. increasing government spending by $25 billion. increasing government spending by $20 billion increasing taxes by $25 billion.
