Explanation
Assume that the economy, as represented by the simple Keynesian model, is in equilibrium with income equal to $6 million and consumption spending equal to $5 million. Which of these is correct? O Investment is $1 million. There is no saving in this economy. The economy will go into disequilibrium because consumption is not equal to income. The information provided is insufficient to determine the level of investment spending.
Keynesian 1) Draw the total expenditure and total production model. 2) Draw the total expenditure and total production model in a recessionary gap. 3) Draw the total expenditure and total production model in an inflationary gap. 4) The following data applies to the economy: Personal Income Consumption $10000 $7000 $12000 $8000 $14000 $9000 The tax rate is 25%. What is the marginal propensity to consume?. What is marginal propensity to save? What is the multiplier for the economy? 5) The marginal propensity to consume is 60%. Government spending increases by $500,000. What is the numeric change in real GDP? What type of spending is this called? 6) The marginal propensity to consume is 75%. Disposable income increases by $500,000. What is the numeric change in real GDP? What type of spending is this called? What is the difference from 5)? 7) The economy is in an inflationary gap of $1,500. What is one fiscal policy the government can undertake to bring the economy to back to the natural…
Assume the marginal propensity to consume is 0.8. To offset a fall in income of 1,000 the government should a. raise taxes by $250. b. increase government spending and taxes by 1,000. c. increase taxes by $200. d. cut taxes by $200.
in a closed economy with no government, where aggregate demand is determinedby autonomous consumption, investment (which is independent of output), and themarginal propensity to consume.a) Given that autonomous consumption is 20, investment is also 20, and the marginalpropensity to consume is 0.6, write out an equation for aggregate demand (AD) in thiseconomy. b) Given this aggregate demand equation, and the equilibrium equation Y = AD, usealgebra to find the equilibrium level of Y. c) Draw a diagram with output (Y) on the x-axis and aggregate demand (AD) on the yaxis. Draw two lines on this diagram: (i) Y = AD, and (ii) the aggregate demandfunction from part (a). Label the intercept of the AD line, and the point where the twolines intersect, with numerical values. (3 marks)d) Suppose that the marginal propensity to consume falls from 0.6 to 0.5. What wouldthe new equilibrium level of Y be? Illustrate your answer in the diagram you drew forpart (c).

Find the equilibrium level of real GDP. C. What is the spending multiolier in this model? Tax multiplier? d. Show that leakages injections at equilibrium. e. If taxes increase by $100, what is the new equilibrium level of GDP? E. Show your answers to b) and e) graphically.
Given the following information, answer the question. Autonomous consumption = R100 million Investment spending = R300 million Government spending = R200 million Taxes = R60 million Marginal propensity to consume = ¾ The equilibrium level of output and income is equal to ______. Select one: A. R2 160 million B. R2 580 million C. R2 640 million D. R2 220 million
14. The economy is experiencing a $225 million inflationary gap. If the government 02 decided to solve this macroeconomic disequilibrium using a change in taxes, would you recommend an increase or decrease in taxes? If the MPC=0.9, what magnitude of tax change would be appropriate?
A country is in the midst of a recession with a real GDP estimated to be $1.8 million below potential GDP. The governement's policy analyss believe the current value of the marginal propensity to consume (MPC) is 0.90. (Please answer all parts) a. If the government wants real GDP to equal potential GDP, by how much should it increase governement spending? Alternatively, by how much should it reduce taxes? b. Suppose that during the recession people have become less confident and decide they will spend only 50% of any additional income. In this case, if the governement increases spending by the amount calculated in part A, will real GDP end up less than , greater than or equal to potential GDP? by how much? c. With the same decrese in consumer spending as described in part B, if the governement decreases taxes by the amount calculated in part A, will real GDP end up less than, greater than or equal topotential GDP? by how much? d. Why is it difficult for the governement to predict…
In a Keynesian model, why would a $100 million increase in government expenditure on goodsand services have a greater impact on aggregate demand than a $100 million reduction in taxrevenue?A Consumers spend only part of any extra disposable income.B Government expenditure does not create wealth.C The marginal tax rate affects the value of the multiplier.D The multiplier does not apply to consumer expenditure.
