We again assume asimple closed economy with GDP of 100 and:c0(autonomous consumption) = 20c1 (marginal propensity to consume) = 0.6I (investment) = 20.a) Now assume that c0falls by 5 (i.e. 5% of GDP), i.e. for any given level of output,consumption will fall by 5. Show the implied fall in the AD function in yourdiagram and show that output will fall by more than 5.b) Show that the multiplier is equal to 2.5, and hence that, in the new equilibrium,output will have fallen by 12.5 (i.e. by 12.5%)c) How big would the impact be if, say, c1 = 0.4 or c1 = 0.8? Explain the difference.
The graph gives an economy's AE curve when the economy is in long-run equilibrium. Equilibrium expenditure is $12 trillion. Draw a new AE curve that shows the effect of an increase in investment. Label it AE₁. Draw a point at the new equilibrium expenditure. Label it B. Draw another AE curve that shows equilibrium expenditure in the short run. Label it AE2. Draw a point at the short-run equilibrium. Label it C. Finally, draw the AE curve when the economy returns to long-run equilibrium. Label it AE3. 16- 14- 12- 10- Aggregate expenditure (trillions of 2012 dollars) 10 A 45 degree line AEO 15 11 12 13 14 Real GDP (trillions of 2012 dollars) >>> Draw only the objects specified in the question. 16

Which of the following correctly describes how a decrease in the price level affects consumption spending? Select one: a. A decrease in the price level raises real wealth, which causes consumption to increase. b. A decrease in the price level decreases the amount of money a household needs to buy goods and so raises the interest rate, which causes consumption to increase. c. A decrease in the price level increases the amount of money a household needs to buy goods and so raises the interest rate, which causes consumption to increase. d. A decrease in the price level lowers real wealth, which causes consumption to decrease.
The graph below shows a 45°-line (Keynesian cross) diagram. The economy is currently in macroeconomic equilibrium at output level Yo. Suppose that investment increases. 1) Use the line tool to show a possible position for the new aggregate expenditures line. Label this line AE2. Note: if you are not prompted for a label, you have used the wrong drawing tool. 2) Use the point drawing tool to show the new equilibrium levels of GDP and expenditures.Label this point 'B'. Real aggregate expenditures, AE Real GDP, Y Y = AE AE0 Q
Use the Keynesian cross model to predict the impact of an increase in government purchases on equilibrium GDP. State the direction of the change and give a formula for the size of the impact. An increase in taxes shifts the planned expenditure function downward. The change in income is given by AY= ΔΥ= -MPC 1-MPC An increase taxes shifts the planned expenditure function upward. The change in income is given by -MPC 1-MPC AY= XAT An increase in taxes shifts the planned expenditure function inward. The change in income is given by AY= 1 1-MPC XAT 1 1-MPC The direction of the shift is undetermined without knowing the slope of the PE function. The change in income is given by XAT XAT
Suppose we have the following information for the simple (fixed r, fixed P, fixed W) Keynesian model. C = 400 + 0.8 I = 310 G = 140 = 400 + 0.8 (Y - T) T = 200, where C is the consumption function, (Y - T) is disposable income, I is investment, G is government spending, and T is taxes. What is equilibrium income ($output), Ye ? Group of answer choices A) $5,050 B) $3,450 C) $6,900 D) $2,050 E) $5,450
