AAAQ1. For this question, note that+++. . .(1+x) (1+x)² (1+X)3Suppose Country X produces 100 units in each period, beginning with period O. Suppose CountryX initially consumes all output, and the interest rate is 0.10.a.If its economy is closed, what is the present value of consumption in Country X? Thepresent value of output? Explain.b. Suppose Country X can invest 34 units in period 0 and increase output by 10 units inevery period thereafter (that is, beginning in period 1). If the economy is closed - thatis, it cannot borrow internationally - should the country do it? If yes, what will be thecountry's consumption in period 1? What will be its consumption in period 2? Showyour work.C.Ignore part b. Suppose now that Country X can invest 34 units in period 0 and increaseoutput by 10 units in every period thereafter, but it now can borrow internationallyto fund the investment. To smooth consumption, how much will it borrow, and howmuch will it consume in each period? Show your work.

(b) By about how much does consumption rise relative to what it would have been without the rise in investment? (c) What is the immediate effect of the rise in investment on consumption? About how long does it take for consumption to return to what it would have been without the rise in investment?

Assume that a nation's marginal propensity to consume (MPC) is 0.75. A highiy productive, cost-cutting technology is developed for the production of commercial airplanes. The total industry expenditure in this nation is $100 million for the immediate acquisition and adoption of this technology. (a) For this nation, identify and explain how much this spending on new technology will change each of the following in the first round: i. Income (GDP) L. Saving i. Consumption (b) Assuming a closed economy and no leakages, identify and explain how much this spending on new technology will change each of the following at the end of the final round: i.

Suppose an economy produces only 2 products that will also be used for directconsumption, as per the article at the end of the exam: chicken wings and donuts. Inthe second quarter of 2021 (the base period), 180,000 pounds of chicken wings wereproduced, at a value of $3.50 per pound, while in the second quarter of 2022,production of chicken wings increased to 200,000 pounds, at a value of $3.75 perpound. In the second quarter of 2021 (the base period), 85,000 donuts were producedat a value of $0.85 per donut, while in the second quarter of 2022, donut productionincreased to 100,000 donuts, each at a value of $0.95 per donut. The population inthis economy is 1000 individuals in 2022, while the number of hours worked in 2022is 5000. Also, the quantities that were produced in 2021 represent the quantities thatwere purchased by the typical household, meaning that everything that was producedwas sold.d. Solve for the amount of labor productivity in the second quarter of 2022.e. Solve for the…
5. Consider the following is the economy of Country Z: C = 200 + 0.85Y I = 100 Answer the following questions: (a) Calculate the equilibrium level of output algebraically using the saving-investment (S-I) approach. (b) What is the value of saving at the equilibrium output from part (a)? (c) Suppose the investment increases to 200. What is the new equilibrium level of output? Calculate the value using the multiplier approach.
QUESTION 1An individual lives for two periods and decides how much to consume in each period.- In the first period his consumption equals C1 and his income Y1 = 200- In the second period his consumption equals C2 and his income Y2 = 100He can save or borrow money in the first period to finance his consumption in the second period.The interest rate he gets in case he saves or has to pay in case he borrows money equals 7%.Determine the budget constraint of this individual. C2 = −0.935·C1 +314C2 =−1.07·C1 +314C2 =−0.8·C1 +314C2 =−1.08·C1 +314 QUESTION 2The total production of a good y is determined by the production function y = 3L2/3K1/3, where L is labour input and K capital input.The reward (factor prices) for labour and capital are, l = 27 en r = 2, respectively.The producer needs to produce 9000 units of good y.How much units of labour will he hire if he wants to miminize his total costs? 1587,4839,953000515,23 QUESTION 3A good is traded on a perfectly competitive…
Assume that GDP ( y) is 6.000. Consumption (C) is given by the equation C= 600 + 06(Y-T). Investment (I )is given by the equation I=2,000- 100r, where r is the real rate of interest in percent. Taxes (T) are government spending (G) is also 500 a. What are the equilibrium values of C, I, and r? b) What are the values of private saving, public saving, and national saving? ·

Using quarterly data from 1947 to the present, graph residential fixed investment relative to GDP a. Compare the graph of residential investment relative to GDP to a graph of the civilian unemployment rate. What happens to residential investment during recessions? In this respect, is residential investment similar to or different from other types of investment? b. During the two decades after World War II, there was an upsurge in population growth and household formation known as the “baby boom.” The baby boom was followed by a “baby bust” during which population growth slowed. How are these demographic trends connected to the behavior of residential investment relative to GDP shown in your graph?
