he marginal propensity to consume (mpc) is 0.8. In addition, government spending increases by $200 billion and lump sum taxes fall by $100 billion. What is the total change in the equilibrium real GDP, if the price level is fixed in the short run?

Answer the following questions, which relate to the aggregate expenditures model: a. If C is £100, I is £50, NX is £-10, and G is £30, what is the economy's equilibrium GDP? Suppose that full-employment (and full-capacity) output in the economy in (a) is £150. Explain the type of gap in this economy and the reasons behind this gap. Clarify the government policies to close this gap.

An economy is described by the following equations: C= 60 +0.75 (Y - T) IP= 100 G= 150 NX= 30 T= 180 Y*= 760 The multiplier in this economy is 4. a. Find a numerical equation relating planned aggregate expenditure to output. Instructions: Enter your response for mpc rounded to two decimal places. PAE= b. Construct a table to find the value of short-run equilibrium output. Instructions: If you are entering any negative numbers be sure to include a negative sign (-) in front of those numbers. Planned aggregate Output Y expenditure (PAE) Y - PAE 620 720 820 920 1,020 Short-run equilibrium output is c. By how much would government purchases have to change in order to eliminate any output gap? By how much would taxes have to change? In order to eliminate any output gap, government purchases would have to be reduced by In order to eliminate any output gap, taxes would have to be increased by d. If Y*=856, then by how much would government purchases have to change in order to eliminate any…

Consider the graph at right showing an economy in recession. Aggregate demand is currently at AD. Equilibrium currently occurs at Eo. If aggregate demand was ADF, there would be full employment. Suppose the government engages in fiscal policy that results in full crowding out. Using the line drawing tool, draw the new demand curve that shows full crowding out. Carefully follow the instructions above, and only draw the required object. Price level Eo EF ADO F Real GDP per Year ($ trillions) SRASO ADF O U

True or false: The slope of the consumption function is the marginal propensity to consume (MPC). Assume the marginal propensity to consume (MPC) is .8. Suppose real disposable income increases by $1000. Solve for the change in consumption. Assume again that the marginal propensity to consume (MPC) is .8. What must be the marginal propensity to save (MPS)? Assume that the marginal propensity to consume (MPC) is .9. Solve for the value of the "simple spending multiplier." Using the value of MPC and the value of the "simple spending multiplier" in question 10, introduce an increase in investment of $1000. Solve for the change in real GDP that results.

The consumption function macroeconomics is often written as C= a + b(Y-T) where b expresses:   a. The marginal savings rate b. The marginal propensity to consume c. The interest rate that maximizes consumption d. The relationship between tax and consumption

For keyboard navigation, use the up/down arrow keys to select an answer. a There is no unplanned changes in inventories. b Investment (I) is equal to Planned Investment Spending (Ip). Income is equal to aggregate expenditures. d All of the above.

Troll Island is a small island nation that recently experienced an autonomous change in aggregate expenditures (AE). AE increased by 5 billion, and the marginal propensity to consume on Troll Island is equal to 0.73. What is the change in Troll Island's real GDP after the increase in AE? Enter your answer in billions of dollars, rounded to one place after the decimal. For example, an answer of $2,500,000 should be entered as 2.5. $ ______ billion

7. Deriving and exploring the total expenditures curve The following graph shows total production (TP) and the level of Natural Real GDP (NRGDP) for a hypothetical economy. When Real GDP is $325 billion, consumption is $275 billion, government purchases are $50 billion, and investment is $25 billion. When Real GDP is $375 billion, consumption is $300 billion, government purchases are $50 billion, and investment is $25 billion. Use the blue line (circle symbol) to plot the economy's total expenditure function within a simplified Keynesian framework. 450 425 X 400 375 TOTAL EXPENDITURE (Billions of dollars) 500 475 350 325 300 300 TP NRGDP 325 350 375 400 425 REAL GDP (Billions of dollars) 450 475 500 TE ?

Which of the following is most likely to cause a decrease in the aggregate expenditure (AE) curve? Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. A decrease in wealth a b A government stimulus check An increase in unemployment benefits d An increase in education spending
