. Suppose the United States economy is repre- sented by the following equations: Z = C + I + G, C = 500 + 0.75YD, T = 600, I = 300, YD = Y − T , G = 2000 Given the above variables, calculate the equilibrium level of output. assume that government spending decreases from 2000 to 1900. What is the new equilibrium level of output? How much does income change as a result of this event? What is the multiplier for this economy?
i need this in word not handwritten Q7. Assume that in 2015, the following prevails in the Republic of Nurd: Y = $200 G = $0 C = $160 T = $0 S = $40 I (planned) = $30 Assume that households consume 80 percent of their in- come, they save 20 percent of their income, MPC = 0.8, and MPS = 0.2. That is, C = 0.8Yd and S = 0.2Yd. Is the economy of Nurd in equilibrium? What is Nurd’s equilibrium level of income? What is likely to happen in the coming months if the government takes no action? 2. If $200 is the “full-employment” level of Y, what fiscal policy might the government follow if its goal is full employment? 3. If the full-employment level of Y is $250, what fiscal policy might the government follow? 4. Suppose Y = $200, C = $160, S = $40, and I = $40. Is Nurd’s economy in equilibrium? 5. Starting with the situation in part d, suppose the government starts spending $30 each year with no taxation and continues to spend $30 every period. If I remains constant, what…
Given C = 200 + 0.60Y How much is consumption when Y = 0 How much is savings when Y = 0 If I = 20, derive and use the multiplier model to calculate the equilibrium Y. Given C and I above, if government increases both G and T by 30, calculate equilibrium Y. Given C and I above, if government only increased G by 30 (no change in T), calculate equilibrium Given C and I above, if government only increased T by 30 (no change in G), calculate equilibrium Why does the increase in G have a larger the effect on Y than the same increase in tax in absolute value terms? Plot the Keynesian Cross diagram (or aggregate expenditure model) that illustrates the equilibrium Y in letter c (label Yc) and letter d (label Yd)
Suppose that the components of planned spending in an economy are C=500 +0.8(Y-T), I=1500, G=2000, X=0, T=0.25Y, where t is the fraction of income paid in taxes (the tax rate). As we will see in this problem, a tax system of this sort serves as an automatic stabiliser, because taxes collected automatically fall when incomes fall.a)Find a short-run equilibrium output in this economy. b)Calculate the multiplier. c)Explain how reducing the size of the multiplier helps to stabilise the economy, holding constant the typical size of fluctuations in the components of exogenous expenditure.
Consider a demand-determined model, with a marginal propensity to consume of 0.80, a marginal propensity to import of 0.25 and a tax rate of 0.20. How much of an increase in economic activity would be generated by a $150 million increase in government spending? (Answers in millions, with no dollar sign - ie. $125,500,000 represented as 125.5) Answer is 245.9, show workings, thanks.
You are given data on the following variables in an economy: Government spending 300 Planned investment 200 Net exports 50 Autonomous taxes 250 Income tax rate 0.1 Marginal propensity to consume 0.5 Use the data above to answer the following questions. Consumption (C) is 600 when income (Y) is equal to 1500. Solve for autonomousconsumption. Solve for the equilibrium level of output in the following two scenarios: there isan income tax t=0.1, there is no income tax in the economy. Denote these two variablesby and respectively. In the economy with an income tax of 10%, what is the budget balance of thegovernment? Solve…
Suppose the United States economy is represented by the following equations: Z = C + I + G C = 500 + .5YD T = 600 I = 300 YD = Y - T G = 2000 a. Given the above variables, calculate the equilibrium level of output. b. Now, assume that taxes increase from 600 to 700. What is the new equilibrium level of output? How much does income change as a result of this event? What is the multiplier for this economy?
Suppose a closed economy with no government spending which in equilibrium is producing an output and income of 2250. Suppose also that the marginal propensity to consume is 0.75, and that, if at full employment, the economy would produce an output and income of 3050 By how much would the government need to cut taxes (T) to bring the economy to full employment?
Assume that in 2015, the following prevails in theRepublic of Nurd:Y = $200 G = $0C = $160 T = $0S = $40I (planned) = $30Assume that households consume 80 percent of their income, they save 20 percent of their income, MPC = 0.8,and MPS = 0.2. That is, C = 0.8Yd and S = 0.2Yd.a. Is the economy of Nurd in equilibrium? What is Nurd’sequilibrium level of income? What is likely to happen inthe coming months if the government takes no action?b. If $200 is the “full-employment” level of Y, what fiscal policy might the government follow if its goal is fullemployment?c. If the full-employment level of Y is $250, what fiscalpolicy might the government follow?d. Suppose Y = $200, C = $160, S = $40, and I = $40. IsNurd’s economy in equilibrium?e. Starting with the situation in part d, suppose the government starts spending $30 each year with no taxationand continues to spend $30 every period. If I remains
Consider the following macroeconomy. All amounts are in millions (m.) of $: C = 750 + 0.8 YD I = 1200 G = 150 T = 250 Calculate eqm Y and prove that I=sum of S at this equilibrium. What is meant by the “Paradox of Thrift” (POT)? Go back to the original eqm of part a. Now prove using multiplier analysis that the POT holds in this economy by assuming that the change in co is -$50 m. As part of your answer, explain “intuitively” why this paradox exists. Show what happens in the Z-Y space graph.
Explain the multiplier intuitively. Why is it that an increase inplanned investment of $100 raises equilibrium output by morethan $100? Why is the effect on equilibrium output finite? Howdo we know that the multiplier is 1/MPS?
Define the concept of equilibrium in the simple expenditure model we developed in class. Now, explain what signal in spending will tell us that the economy is not in equilibrium? Lastly, assume that we find that actual Y is greater than equilibrium Y, Ye thus actual current Y>Ye. Explain the reaction by firms to this situation and what you expect to happen to the actual level of Y because of this corporate reaction. Show the graph of the initial situation and the resulting change in Y due to the corporate reaction.
