- Q) Consider the multiplier model (in which the only component of expenditure that depends on income is consumption), and suppose that investment expenditures decrease by $50 million. All else equal, then the spending-balance level of output will A) increase by $50 million B) decrease by $50 million C) decrease by more than $50 million D) decrease by less than $50 million Explain it early and correctlyTable 2 shows elements in the national income accounts of an economy. Assume the economy is currently in equilibrium. elements billions Consumption (total) 80 Investment 9 Government Expenditure. 6 Imports 15 Exports 8 C) If national income now rises by £22 billion and as a result, the consumption of domestically produced goods rises to £80 billion. Calculate the marginal propensity to consume (MPC). D) What is the value of the multiplier? E) Comment on the results in part (c) and (d).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 ?
- (a)Elaborate THREE (3) determinants in which consumption can be increased according to the consumption function. (b)Assume that a three-sector economy in Country W. The amount of autonomous consumption is RM300 million with the proportion of an increase in income that is spent on consumption is 0.5. An induced tax of 20% is imposed by the country. The amount of investment is RM250 million, and the amount of government spending is RM150 million. (i)Calculate the national income equilibrium. (ii)Based on your answer in (i), show the aggregate expenditure graph. (iii)Explain what would happen to the national income equilibrium if the investment changes by RM100 million.In an economy, autonomous consumption expenditure is $50 billion, investment is $200 billion, and government expenditure is $250 billion. Exports are $500 billion and imports are $450 billion. Assume that net taxes and imports are autonomous and price level is fixed. a)What is the consumotion function? b)What is the equation of the aggregate expenditure curve? c)Calculate equilibrium expenditure. d)Calculate the multiplier. e)If investment decreases to $150 billion, what is the change in equilibrium expenditure ?Given Co = 400 and MPC=0.70 Does MPS + MPC = 1? If autonomous consumption increases by $50. What is the multiplier? What is the change in total spending? Use a diagram to show which curve shifts and how.
- Macroeconomics Question No.2 Suppose the consumption function is given by C = 100 + 0.8YD and that I = 50, while G=200, TR=62.5 and t=0.25. What is the equilibrium level of income? What is the level of saving in equilibrium? If investment were to rise to 150, what would be the effect be on equilibrium income. What is the value of multiplier in part a. and c. Draw a diagram indicating the equilibrium in part a. and c.Complete the following table:a. Show the consumption and saving schedules graphically.b. Find the break-even level of income. Explain how it is possible for households to dissave at very low income levels.c. If the proportion of total income consumed (APC) decreases and the proportion saved (APS) increases as income rises, explain both verbally and graphically how the MPC and MPS can be constant at various levels of income.Define marginal propensity to consume (MPC) and the multiplier (M) .Explain in detail .
- Consider an economy where the aggregate planned expenditure (AE) components are given by: Consumption (C) = 1000 + 0.8Y Investment (I) = 200 Government Expenditure (G) = 250 Exports (Ex) = 400 Imports (Im) = 200 + 0.133Y Write the AE equation (simplified). Identify the autonomous component and the induced component. Graph the AE curve. Find and identify on the graph the equilibrium expenditure. Show on your graph the effect of an increase of 60 in government expenditure and find the new equilibrium expenditure.
