- Explain how to derive a total expenditures (TE) curve.Assume you have the following model of the expenditure sector: AD = C + I + G + NX C = Co + cYD YD = Y - TA + TR TA = TAo TR = TRo I = Io G = Go NX = NXo If a change in exports by deltaNX = - 200 is accompanied by a change in consumption by ∆C = - 800, what is the size of the expenditure multiplier?The economy of HOYA has a spending mulipilier of 4. Based only on this information, we know that in HOYAO. Every one point change in R will change spending by 4O. An $80 decrease in investment will reduce GDP by $20O. A $10 increase in not exports will lead to a $40 income equilibrium GDPO. $25 increase in goverment purchase will increase equilibrium consumption by $100
- THE AGGREGATE EXPENDITURE MODEL (IN THE SHORT RUN)YOU MUST SHOW YOUR CALCULATIONS IN THE SPACE BELOWFOR THE NEXT PROBLEM USE THE FOLLOWING FORMULA:CHANGE IN GDP = [ 1 / (1-MPC) ] * CHANGE IN GInitially, the economy is producing $13 trillion in goods and services and the government is spending $2 trillion.Then the government decides to increase its spending to $2.7 trillion. What is the value of the spending multiplier?AD shocks change the equilibrium level of income(Y)and price(P). But the division of effects between P and Y depends on the shape of the SRAS curve. Using graphs show us what happens to P ,Y and the size of multiplier whena. SRAS is verticalb. SRAS is horizontalDerive the consumption function and use this relation in the aggregate demand function to derivean equation for the equilibrium in the goods market . Why the AD line is upward sloping?Suppose the government spending falls by 100 and in this case marginal propensity to consumeis 0.8. what is the value of change in output. Draw a diagram to show the shift in AD line due tothis change in government spending and output.
- Given Co = 400 and MPC=0.70 Does MPS + MPC = 1? If autonomous consumption increases by $50. What is the multiplier? What is the change in total spending? Use a diagram to show which curve shifts and how.If the recessionary gap is $ 200 billion and the multiplier is 2, what is the increase in aggregate spending needed to bring the economy to full employment? a)$300 billion b)$ 600 billion c)$200 billion d) $66.6 billionAD shocks change the equilibrium level of income(Y)and price(P). But the division of effects between P and Y depends on the shape of the SRAS curve. Using graphs show us what happens to P ,Y and the size of multiplier whena. SRAS is upward slopingb. SRAS is upward sloping and flatterc. SRAS is upward sloping and steeperd. SRAS is verticale. SRAS is horizontal
- Draw and interpret a “Keynsian cross” graph for the following situations. See the model in ch. 12. (Each can be analyzed independently of the other, so separate graphs for each part). briefly interpret by answering: Which component of aggregate expenditure (AE) shifted? Why? How did that shift the AE curve? What happens the economy’s output and income? For the latter, use the concept of changes in inventory and interpret the graph. Sign your graph and include the picture. a) The stock market reaches another all-time high. Consumers are wealthier and businesses are feeling confident. b) The Federal Reserve decides to end the record low interest rate environment and increases rates across the term structure by 200 basis points.Consider a 4-sector economy, the consumption spending is C = 500+0.75(Y-T), taxes are T = 10 + 0.2Y, and imports are M=0.2Y. Planned investment is Ip=300, government spending is G=250, and exports are X=10. What is the slope of the planned aggregate expenditure (PAE) line? a) 0.7 b) 0.5 c) 0.6 d) 0.3 e) 0.497) You observe that unplanned inventories are increasing. You predict that there will be ________. A) a business cycle B) an expansion C) a trough D) a recession 98) Business cycle turning points are A) unaffected by, and unrelated to the multiplier. B) easy to predict. C) brought about by changes in autonomous expenditures that are then subject to the multiplier effect. D) None of the above is correct. 99) Which of the following does NOT occur as the economy moves from an expansion to a recession? A) An initial decrease in autonomous spending is the trigger that creates the business cycle turning point. B) The change in planned spending exceeds the change in real GDP. C) The multiplier process reinforces any decrease in spending and pushes the economy into recession. D) Incomes fall during recessions as firms cut production in response to unplanned increases in inventories. 100) Which of the following is INCORRECT? A) Expansions usually begin…
