The graph models an economy in equilibrium with a real GDP of $180 billion. Suppose that consumers' expectations about future incomes change, causing unplanned inventory investment to increase by $30 billion. Shift the planned aggregate expenditure (AE) line to show the effect of this change. *Image* 1) This change will cause the equilibrium level of real GDP to a) decrease. b) remain unchanged. c) increase. 2) By how much will GDP change once the new equilibrium is reached? If GDP will decrease, be sure to include a negative sign. GDP change: $ ________ billion
Suppose an economy had aggregate demand components with the following relationships: Consumption spending, C=140+.60*(DY) Investment spending,I=25+.15*Y Government Spending, G= 0 Net Export Spending,X=0 Tax collections, Tx=0 a. What is the equilibrium income for this economy? b. If the government decided to increase G spending by 6, what would be the new equilibrium income for this economy? c. If instead the government decided to reduce Tx (taxes) by 10, what would be the new equilibrium income for the economy? d. If instead the government decided to increase G spending and Increase Tx (taxes) by 20, what would be the new equilibrium for this economy?
Determine aggregate expenditures (AE) in this economy when real GDP (Y) is equal to $1,500 billion, $2,000 billion, and $2,500 billion.When Y = $1,500 billion, AE = billion .When Y = $2,000 billion, AE = billion . When Y = $2,500 billion, AE = billion .
In an economy, autonomous consumption expenditure is $50 billion, investment is $200 billion, and government expenditure is $250 billion. Exports are $500 billion and imports are $450 billion. Assume that net taxes and imports are autonomous and price level is fixed. a)What is the consumotion function? b)What is the equation of the aggregate expenditure curve? c)Calculate equilibrium expenditure. d)Calculate the multiplier. e)If investment decreases to $150 billion, what is the change in equilibrium expenditure ?
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. Compute the new equilibrium level of output. Assume that the marginal propensity to consume is 0.7 (MPC=0.7).
Troll Island is a small island nation that recently experienced an autonomous change in aggregate expenditures (AE). AE increased by 77 billion, and the marginal propensity to consume on Troll Island is equal to 0.850.85. 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.
Assume the level of autonomous investment is $100 billion and aggregate expendituresequal consumption and investment. Based on the following table, answer the followingquestions. a. Fill in the unplanned inventory column.b. Determine the MPC and MPS.c. If this economy employs a labor force of 40 million, what will happen to this level of employment? Explain and identify the equilibrium level of output.
From the information below calculate aggregate demand; Consumption (C) = $200 + 0.6Y Investment (I) = $300 Government (G) = $100 Net Export (NX) = $50 Which one of the following statements about Consumption and Aggregate Demand is CORRECT when the economy achieves equilibrium GDP? a. One is 350 greater than the other b. One comprises the other c. They are valued at $1025 and $1375, respectively d. They are valued at $1375 and $1025, respectively e. They are both the same
Derive 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.
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
Consider the following initial conditions (where all dollar amounts are in billions): C = 600 + 0.6y D , I = 400, G 1 = 300, T 1 = 200 A. Given these initial conditions, calculate y*. Draw a rectangle around the expenditure equation resulting from step I and your calculated y* in step II. Draw a graph showing the total expenditure (E) curve and y*. Label y*, E*, and the E-intercept of the expenditure equation. If yF were $3,100, would the economy be in a recessionary gap or an inflationary gap? What is the size of the gap? Label yF and show the gap on the graph from B. If the government were to try to close the gap by changing the level of government spending, how much of a change (∆G) would be necessary to close the gap? What would be the new level of government spending (G2 )? What is the new expenditure equation (draw a rectangle around it)? On the graph from part B, draw the new expenditure curve, E2 , and label the new y* and the new E intercept. Alternatively, if the…
If investment increases by $50 billion, by how much will aggregate demand change? Aggregate demand will _______. A. increase by less than $50 billion because there will be fewer goods and services produced for consumption expenditure B. increase by more than $50 billion because the increase in aggregate income induces an increase in consumption expenditure C. probably decrease by $50 billion, but it depends on the change in aggregate supply D. increase by exactly $50 billion because investment is a component of aggregate demand
