Calculate the total change in aggregate spending if investment increases by $200 billion and the marginal propensity to consume is 0.8.
Answer
Multiplier =1/(1-MPC)
=1/(1-0.8)
=5
total change in aggregate spending =change in investment *multiplier
=200*5
=$1000
the total change in aggregate spending is $1000 billion

1.) If the marginal propensity to consume is 0.75 and investment spending increases by $200 billion, equilibrium GDP will increase by____. $350 billion $150 billion $200 billion $266.7 billion $800 billion 2.) AE = 3000 + 0.75*RGDP. Given this equation for AE, find equilibrium GDP $1,000 $750 $12,000 $2,250 3.) The four components of aggregate planned expenditure are the real interest rate, disposable income, wealth, and expected future income the real interest rate, consumption expenditure, investment, and government expenditures consumption...
If the marginal propensity to consume (MPC) is 2/3 and investment spending increases by $2 billion, the level of real output (GDP) will: increase by $10 billion. O increase by $3 billion. increase by $6 billion. O Increase by $8 billion
Suppose the marginal propensity to consume is 0.8. The government increases government spending and taxes by $10 billion. What happens to aggregate output demanded?
Suppose that investment demand increases by $200 billion and no leakages occur except household saving. Assume further that households have a marginal propensity to consume of 75 percent. Instructions: Enter your responses rounded to one decimal place. a. Compute four rounds of multiplier effects. Changes in This Cycle's Spending Cumulative Change in Spending (in billions) (in billions) First cycle $200.0 $200.0 Second cycle Third cycle Fourth cycle b. What will be the final cumulative impact on spending? billion
If the marginal propensity to consume (MPC) equals 0.25 and the government increases spending by $600 billion, the total impact on GDP will be approximately:
Suppose that investment expenditures increases by $300 billion in a closed and private economy (no government or foreign trade). Assume further that households have a marginal propensity to consume of 75 percent. What will be the final cumulative impact on spending? $900 billion $225 billion $375 billion $525 billion

Suppose economists observe that an increase in government spending of $5 billion raises the real aggregate output level by $20 billion. (a) In the absence of the crowding out effect, what would the numerical value of marginal 1. propensity to consume (MPC)? (b) Now suppose the crowding-out effect also comes to play.Should the new numerical value of marginal propensity to consume (MPC) be larger or smaller than that of your answer in part (a)? Explain. (Hint: the multiplier effect and...
