- ADVANCED ANALYSIS Assume that the consumption schedule for a private closed economy is such that consumption is: C = 100 + 0.75Y Assume further that planned investment Ig is independent of the level of real GDP and constant at Ig = 50. Recall also that, in equilibrium, the real output produced (Y) is equal to aggregate expenditures: Y = C + Ig Instructions: Enter your answers as whole numbers.a. Calculate the equilibrium level of income or real GDP for this economy. Equilibrium GDP (Y) = $ . b. What happens to equilibrium GDP if Ig changes to 60? Equilibrium GDP (Y) = $ . What does this outcome reveal about the size of the spending multiplier? Spending multiplier = .2. In macroeconomic theory, total or aggregate spending is denoted by A and total or aggregateproduction of income by Y. Which one of the following statements is incorrect? A When A is greater than Y, there is disequilibrium and Y will tend to increase.B When A is equal to Y, there is equilibrium and Y will remain unchanged.C When A is less than Y, there is disequilibrium and Y will decrease.D When A is greater than Y, there is disequilibrium and A will decrease.Question:Given that the marginal propensity to consume in a fully employed closed economy is 0.75, an increase in government expenditure of $1,000 million will increase the national income by:a. $0b. $750c. $4,000d. $7,500e. $8,000
- 1. In using the expenditure approach to GDP, consumption.... 2.The long -run aggregate supply curve is ? 3. National saving equals private saving plus government saving ,which inturn equals? 4. The mpc and mps measures charges in consumption expenditure and saving that result from changes in ? 5. The sum of the components aggregate expenditure that are not influence by real GDP is called ?Scenario 2Suppose the marginal product of capital is MPK=2-0.001K, the capital stock depreciates at 20% rate, the tax rate on revenues is 20% and price of capital is assumned to be 1. Furthermore, the economy has full-employment level of output of 5000, government purchases are 1000. Desired consumption is given by C^d=3000-2000r+0.1Y, where Y is output and r is expected real interest rate. Initial level of capital is 1000.Refer to Scenario 2. what is the expression for desired gross investment ? A) I^d=950-1250r B)I^d=950+1250r C)I^d=1750-1250r D)I^d=1950-1250r.Scenario 2Suppose the marginal product of capital is MPK=2-0.001K, the capital stock depreciates at 20% rate, the tax rate on revenues is 20% and price of capital is assumned to be 1. Furthermore, the economy has full-employment level of output of 5000, government purchases are 1000. Desired consumption is given by C^d=3000-2000r+0.1Y, where Y is output and r is expected real interest rate. Initial level of capital is 1000. Refer to Scenario 2. What is goods market clearing real interest rate? A)r=13.84 B)r=15% C)r=2% D)r=16%
- Suppose that consumer spending initially rises by $5 billion for every 1 percent rise in household wealth and that investment spending initially rises by $20 billion for every 1 percentage point fall in the real interest rate. Also assume that the economy’s multiplier is 4. b. In what direction and by how much will it eventually shift?a) What generally happens to the major macroeconomic variables such as GDP, unemployment rate, and inflation rate during an economic recession? b) Define economic expansion using the reference terms of actual GDP and potential GDP. c) Explain how investment spending and interest rate related. What is the reason behind such a relationship? d) Find the correlation coefficient between interest rate and Real Investment. Does this (actual) value support the theoretical relationship between the variables? Explain. (e) Explain the importance of investment spending for the economy. Only typed answerFor an economy the following functions have been given:C = 100 + 0.8YS = -100 + 0.2YI = 120 – 5rMs = 120Md = 0.2Y – 5rCalculate the following:5.1.1. IS equation 5.1.2. LM equation 5.1.3. Equilibrium level of income 5.1.4. Equilibrium level of interest rate. 5.1.5 Calculate National saving. 5.1.6 Calculate money demand 5.1.7 Find consumption
- a. What is the equilibrium rate of real GDP? $ __ billion b. If full-employment real GDP is $800 billion, what problem does this economy have? multiple choice This economy has a recessionary gap. This economy has an inflationary gap. This economy does not have a problem. c. How large is the real GDP gap? $ __ billion5 3. permanent Income Hypothesis a) suppose that beta=.9 and R= 2222 (that is ~22%). For an individual who acts according to the PIH, will their consumption next period be higher than current consumption or lower? b) What is the main crucial difference between the Keynesian Consumption function and the consumption function derived from the PIH (or Lifetime Income Hypothesis)? c) If Present Value of future income stream is 500,000 and a person has a beta of.8, how much will their consumption go up today if only today's income increases by 1000? How much will their consumption increase (approximately) if their income goes up by 1000 in all periods?ax policy is one used not only for economic purposes but also for political purposes. It is the opinion of some economists and politicians that the rich should pay more of their income in taxes, and that the resulting fairness from this rise in taxes will lead to more economic growth and a rise in employment. Using the simple expenditure model (Y and Ep, not IS-LM) answer these two questions: One, would a lump-sum tax increase on many high-income households cause GDP to rise in the short run as predicted by the politicians? Why or why not? And two, are there macroeconomic conditions in the simple model under which such a tax increase would be fully warranted? Draw the graphs and explain the outcomes for both cases.
