Macroeconomics: Assuming marginal propensity to consume is 0.5. If there is a shock to the economy that increases investment spending by 200 billion dollars what will the total Change to GDP be? (Ignore taxes and imports)

Multiplier Effect Question, Initial investment of 2 billion and getting 9 billion in total revenue after reinvestment

Question 2 Refer to the information provided in Figure 23.9 below to answer the question(s) that follow. Aggregate expenditures ($ millions) 225 200 175 150 45° AE 100 200 300 Aggregate output ($ millions) Figure 23.9 a) Refer to Figure 23.9. Write the equation for the aggregate expenditure function (AE). Show your work. b) Refer to Figure 23.9. What is the equilibrium level of output in this economy? State the equilibrium condition used to determine this. c) Explain the forces that maintain/drive the economy to this equilibrium by considering what will happen at the following two levels of output, $300 million and $100 million. You will need to discuss changes in investment through unplanned inventories and the response of output. d) Refer to Figure 23.9. How will equilibrium aggregate expenditure and equilibrium aggregate output change as a result of a decrease in investment by $20 million? e)The interest rate is an exogenous factor that effects the level of investment in an economy.…

K The following equations describe consumption, investment, government spending, taxes, and net exports in the country of Economika. In Economika, equilibrium GDP is equal to $. (Round your asnwer the nearest dollar.) If real GDP in Economika is currently $4,850, which of the following is true? A. There will be an unplanned decrease in inventories, and real GDP will increase next period. OB. There will be an unplanned increase in inventories, and real GDP will increase next period. OC. There will be an unplanned decrease in inventories, and real GDP will decrease next period. O D. There will be an unplanned increase in inventories, and real GDP will decrease next period. OE. There will be no unplanned change in inventories, and real GDP will stay the same next period. C=200+0.80(Y-T) 1=400 G=350 T=350 X = 100

15. Total expenditures in a country (in billions of dollars) are increasing at a rate of f(x) = 8.22x+87.13, where x = 0 corresponds to the year 2000. Total expenditures were $1584.9 billion in 2002. a. Find a function that gives the total expenditures x years after 2000. b. What will total expenditures be in 2016? a. What is the function for the total expenditures? F(x)= (Simplify your answer. Use integers or decimals for any numbers in the expression.) b. In 2016, total expenditures will be S (Type an integer or a decimal.) billion.
