Only typed answer Assume that marginal propensity to consume is 0.8 and full-employment level of output is $800 billion. If the actual real GDP is $700 billion, find the change in lump-sum taxes that would bring the economy back to its full-employment level of output (assume taxes and transfer payments do not depend on income and the economy is a closed economy).
Consider a closed economy in which: C=250+0.8 (Y-T)I=400−30 rT=150G=220Y=C+I+G where Y is GDP, C is consumption, I is investment, T is taxes, G is government purchases, and r is the interest rate. If the economy were at full employment (that is, at its natural rate), GDP would be 3,000. Assuming no change in fiscal policy, what change in the interest rate (Δr) would restore full employment? Δr=______ Assuming no change in monetary policy, what change in government purchases (ΔG) would restore full employment? ΔG=______
4. The country of Merryville has an unemployment rate that is greater than the natural rate of unemployment.The government of Merryville increases spending on goods and services by $200 billion, which is financed by borrowing. If the marginal propensity to consume in Merryville is 0.75:i. Calculate the multiplierii. What is the maximum possible change in real gross domestic product (GDP) that could result from the $200 billion increase in government spending?

10.1For each of the following events,explain the short-run and long-run effects on output and price level,assuming policymakers take no action. a) The stock market declines sharply,reducing consumers' wealth. b) The federal government increases spending on national defence. 10.2 In which of the following circumstances is expansionary fiscal policy more likely to lead to a short-run increase in investment?Explain. a)When the investment accelarator is large or when it is small?
Suppose the following equations represents a closed economy: Y= C + I + G Y = 4000 G = 500 T = 500 C = 500 + 0.7 (Y – T) I = 1000 – 40r In this economy, compute the value of consumption (C), private saving, public saving, and national saving. Also, find the equilibrium interest rate (r). Now suppose that government spending (G) rises (expansionary fiscal policy) to 300. Compute private saving, public saving, and national saving. Also, find the new equilibrium interest rate (r). In part (b), due to expansionary fiscal policy (increase in government spending), which of the two other components of aggregate demand changes, C or I? Why? (Hint: Note the real interest rate)
Assume that total expenditure E comprises the sum of government consumption, G, household consumption, C, and investment, I. Assume a closed macroeconomic system, so that income equals expenditure Y=E. If we define household saving, SH, as SH=Y-T-C, where Y is national income and T is total taxation, which of the following will be true? a. SH=I+G b. SH=I-G-T c. SH=I+(G-T) d. SH=I
Consider an economy similar to that in the preceding question in which investment is also $200, government purchases are also $500, net exports are also $30, and the price level is also fixed. But taxes now vary with income and, as a result, the consumption schedule looks like the following: GDP Taxes DI C $1,360 $320 $1,040 $810 1,480 360 1,120 870 1,600 400 1,200 930 1,720 440 1,280 990 1,840 480 1,360 1,050 Find the equilibrium graphically. What is the marginal propensity to consume? What is the tax rate? Use your diagram to show the effect of a decrease of $60 in government purchases. What is the multiplier? Compare this answer to your answer to Test Yourself Question 1. What do you conclude? GDP…
Using what you know about national income accounting, answer the following as true, false, or uncertain and justify your answer: [Assume households either consume or save their income only.] a)If the private sector is balanced and transfers are held constant, an increase in taxes implies a decrease in net exports. b)An increase in disposable personal income must imply an increase in private investment. c)Holding the government budget deficit constant, an increase in net exports must imply an increase in disposable income.
I and T are fixed (I=Io and T=to), so we know that if households attempt to save more, cet. par., Private saving will rise and the government budget deficit (GBD) will fall. Private saving will fall and the GBD will rise. Private saving will not change, but the GBD will rise. none of the above Provide appropriate name(s) and explain using I=sum of Saving.
