Question 32 Consider the following information describing an economy with demand-determined output. There is no government or foreign trade. All dollar figures are in billions. 1. equilibrium condition is Y = C +| 2. marginal propensity to save = 0.20 3. the autonomous part of C is $50 4. investment is autonomous and equals $25
Suppose the desired consumption function of Canadaland is given by C^d= 0.5 + 0.7Y - 10r - 0.1G, where Y is income, r is the real interest rate, and G is government purchases. This implies that a. Desired consumption is increasing in the real interest rate b. The marginal propensity to consume is 0.5 c. The marginal propensity to consume is 0.75 d. Desired consumption is increasing in governmental purchases
Consider an economy located near the Indian Ocean where the main industries are agriculture and tourism. Policymakers and economic advisors have determined that consumers' spending behavior is described by the equation: C = 255 + 0.75DI while the domestic investment spending behavior by firms is fixed at $250 billion. Currently, the population is 250 million, the labor force participation rate is 68 percent, and the unemployment rate is 4 percent. The policymakers and economic advisors have also determined that the short run aggregate supply of goods and services in the economy is described by the equation Y = Ypot + 75(P - Pe), while the potential level of real GDP is $2075 billion and the expected price level at full employment, Pe, is 115. Net taxes is described by the equation: T = 120 + 0.2Y while the government spending is fixed at $500 billion. Trading occurs mostly with neighboring economies and currently total imports is $300 billion while total exports is $200 billion.…

supply equation is Y - Ypot + 80 (P-Pe), where Ypot is the potential level of output. In 2016, the population was 400 million, and the structure of the economy was described by the following equations for household consumption behavior and taxes received: C = 100+ 0.8DI, and T = 0. where all monetary values are in billions of dollars. Government spending was fixed at $1700 billion, and firm's investment behavior was fixed at $800 billion. Trading is allowed in this economy and in 2016, trading occurred such that the trade account was balanced. That is, net exports (X-IM) was equal to zero. (Question 15 of 20) Now consider that in in the following year (2017), the government decided to implement a policy aimed at moving the economy to full employment. In its decision to move the economy to full employment, they used government spending as the policy tool. The structure and fixed spending behaviors remain the same as they were in 2016, except for government spending. In addition, changes…

If the marginal propensity to save (MPS) is 0.70 and autonomous consumer spending is 100, what is the aggregate consumption function? C= 0.80*Y + 100 C= 0.80*Y + 80 C= 0.20*Y + 80 C= 0.30*Y + 100
Consider an economy in which taxes, planned investment, government spending on goods and services, and net exports are autonomous, but consumption and planned investment change as the interest rate changes. You are given the following information concerning autonomous consumption, the marginal propensity to consume, planned investment, government purchases of goods and services, and net exports: Ca = 1,500 – 20r, c = 0.6; I= 2,450 – 60r; G= 1,980; NX =- 200; T = 1,750. a. Compute the value of the marginal propensity to save. b. Compute the amounts of autonomous planned spending, Ap, when the interest rate equals 0, 2, 4, and 6. c. Compute the equilibrium levels of income when the interest rate equals 0, 2, 4, and 6. Graph the IS curve. d. Suppose that policymakers decide to reduce the number of troops in Afghanistan, which results in a reduction of government spending of $80 billion. Compute the new amounts of autonomous spending, Ap, when the interest rate equals 0, 2, 4, and 6. e.…
Suppose a closed economy has an aggregate consumption function given by C = 100 + 0.75Yd and generates $3000 output and income in equilibrium. Suppose also that the government spends 300 and imposes a lump-sum tax of 50. What is the level of intended investment? (round your answer to the nearest whole value)
Consider a closed economy. Let Y denote GDP, C denotes Consumption, I denotes Investment, r is the real rate of interest in percent, T denotes Taxes, and G stands for Government Spending. Suppose that these take the following form: Y = 8,000.C = 600 + 0.8(Y – T) I = 2,000 – 100rT = 500G = 500. a. What is the marginal propensity to consume in this economy? b. What are the equilibrium values of C, I, and r? c. What are the values of private saving, public saving, and national saving? d. If government spending rises to 1,000, what are the new equilibrium values of C, I, and r? e. What are the new equilibrium values of private saving, public saving, and national saving?
