- Question 8 Real GDP in the economy is $7,900 Billion and the Marginal Propensity to Consume is 0.56. What will Real GDP in the economy be, in $ Billions, after a $10 Billion increase in Government Spending? (Round your FINAL answer to the nearest whole number/integer.) (BE VERY CAREFUL NOT TO ROUND "MIDDLE" CALCULATIONS. ONLY ROUND THE FINAL ANSWER.) (Do not enter a dollar sign, $. or the word "Billion", just the number.)Discuss, with the aid of a diagram, the consumption function according to the Keynesian School of Thought. (You will need to provide a diagram)a) About Country A, what is your estimate of the country's marginal propensity to consume (MPC) based on the following information on its GDP (Y) and the components thereof (in billion dollars) for two past years? Show calculation. Year 1 Year 2 c) GDP C I 11200 8000 2200 12000 8500 2400 G 800 880 The next few parts are about Country B, whose government plans to cut taxes by $24 billion as a measure to fight the current recession. The marginal propensity to consume (MPC) in Country B is known to be 34. There will be no crowding-out effect. e) NX 200 220 b) What is the initial effect (in billion dollars) of the tax cut on Country B's aggregate demand? (The "initial effect" here refers to the effect on AD after only the first round of increased spending.) What is the total effect of the tax cut on aggregate demand? Explain why it is different from the initial effect. d) How does the total effect of this $24 billion tax cut compare to the total effect of a $24 billion increase in…
- Consider an economy in which autonomous consumption, planned autonomous investment, autonomous government expenditure, autonomous taxes, and the marginal propensity to consume are given (there are no net exports). Autonomous consumer spending = $3,000 Ip = $5,000 G = $3,000 T = $4,000 MPC = .75 (a) What is the level of C when Y = $19,000? I need help to know how to calculate this.Suppose that Jane’s income increases from $1700 per month to $2350. At the same time, her consumption changes from $950 per month to $1300 month. What is Jane’s marginal propensity to consume? (Round your answer to two decimal places.)The marginal propensity to consume for this economy is …………. if income rises from $9000 to $10000 and consumption is rises from $750 to $1500 0.650. 0.750. 0.650 or 0.664, depending on whether income is $10,000 or $11,000. 0.800.
- 10 . In the “complete Keynesian model”, the investment functions was I = I0 - f(i). An analyst now proposes the following investment function: I = I0 - f(i) + qY, where “q” is a parameter and Y is national income = GDP. Provide two different arguments, i.e. explanations as to why this investment function makes sense. The focus is on the new term, qY (q times Y), in the function.For the following problem, assume that the MPC, b, takes into account how much consumers spend as total income (Y) in the economy is changes. (Also: Hint GDP = Total Y) So we can rewrite our consumption function as :C= a +bYAssume:a= $2900 billionb=.75GDP= $9,000 billion.A) What is C=B) What is S=C) If consumers were the only ones buying goods in the economy, would the economy have an excess supply of goods, excess demand of goods or would the economy be at equilibrium ?Question 1 (14 marks) Consider the following numerical example of the simple Keynesian model with no government spending, taxes or a foreign sector (all figures in R millions): C = 100 + 0,9Y I = 50 Answer the following questions. What is the value of the marginal propensity to consume (MPC) in this model? (2) What is the value of the multiplier in this economy? (3) Calculate aggregate spending in this economy (2) Calculate the equilibrium level of output. (3) Suppose the level of output that creates full employment (Yf) in the economy is 1 800. Determine the level of investment spending that would create full employment in this economy. (4)

Planned investment is 100; government purchases and taxes are both 100. (solve three tasks) Graph planned expenditure as a function of income. What is the equilibrium level of income? If government purchases increase to 125, what is the new equilibrium income?
