- The national income model for an economy is represented as follows (units are in Ksh.M) Y = C + I + G + X – M I = 320 + 0.20Y G = 980 C = 540 + 0.80Y M = 640 + 0.25Y X = 850 Y = National income; C = Consumption; I = Investment; G = government spending; X = Exports; and M = Imports. Determine the following.TRUE or FALSE: This model has three endogenous variablesAnswer 1Choose... TRUE or FALSE: The country’s marginal propensity to save is 20%.Answer 2Choose... Autonomous level of importsAnswer 3Choose... Equilibrium investment Answer 4Choose... Equilibrium national incomeAnswer 5Choose... Net Exports (NX) Answer 6Choose... TRUE or FALSE: The economy is a net importerConsider a national income model as: Y= C + I0 + G Y= National Income C= (Planned) Consumption Expenditure I0= Investment G= Government Expenditure Consider Y= 20trillion, G= 4.2trillion, I0= 3.8 trillion. Explain the key elements missing from the National Income model. Add a new endogenous variable to represent that missing element or endogenize one of the exogenous variables to address this issue. C= a+ b(Y-T0) (a>0, 0<b<1) G= gY (0<g<1)Consider the following model of national income determination C = 3000 + 0.75 (y- t) T = 1000 I= 4750 G = 1500 Y=E=C+I+G Solve for the equilibrium values for all the endogenous variables Suppose the government expenditure increased by 500 find the new equilibrium value Calculate the value of the government spending multiplier
- Consider a simple model, such as the one developed in this chapter. The table to the right shows the levels of desired consumption, desired investment, and desired aggregate expenditures for various levels of actual national income.Suppose an economy is described by the following equations: Y = C + I + G + X – M C = 14 + 0.60Yd I = 20 G = 20 X = 15 M = 5 +0.1Y T = 20 + 0.4Y Where Y is domestic income Yd is private disposable income C is aggregate consumption spending T is government tax revenue I is investment spending G is government spending E represents exports M represents imports of goods and services. (a) If the equilibrium national income is less than the full-employment level of income by N$100, what should be the increase in government spending or in exports to attain the full-employment level of income? (b) With a help of a diagram explain and discuss life cycle hypothesis.Let the national income model be; Y = C + I0 + G , C = a + b ( Y – T) , G = g Y Identify endogenous variables Find the equilibrium national income Find equilibrium consumption(using static equilibrium & matrix algebra both
- Consider a macroeconomy where the current population is 800 thousand people. Gross domestic private investment is constant $2500 million while consumer expenditure is described by the equation: C = 580+ 0.8DI. The government is fairly active, with a total expenditure of $2000 million and net taxes of $2550 million. Further investigation of the macroeconomy reveals that imports are constant at $3000 million while exports are constant at $2500 million. Currently, the overall price level (GDP deflator) is 118 and the potential GDP level is $13.5 billion. What is the current equilibrium level of real GDP? (report your answer at 2 decimal places and in millions of dollars) 1. What is the current equilibrium level of real GDP 2. what is the current real GDP per capita? 3. what is the value gap?Suppose the aggregate expenditure schedule for an economy is given by the equation: AE = 800 + 0.8Y Where AE represents the aggregate expenditure and Y represents the national income (output) level. Calculate the equilibrium level of national income in this economy.Suppose that the level of income is $1000 and the tax rate is 0.1 %. Given this data, what is the level of disposable income? Use the following information to answer questions 5 through 8: Consider the following information for Slovenia. Category Amount Autonomous Consumption 430 MPC 0.9 Tax Rate 0.25 Investment 800 Government Expenditure 100 Exports 20 MPI 0.05 What is the equilibrium level of GDP in the income-expenditure model? Suppose that there is a decrease in Exports by $20. What is the new equilibrium level of GDP in the income-expenditure model? What is the difference between the original and new GDP as a result of a decrease in Exports? Suppose that MPC is equal to 0.8. What is the spending multiplier?
- 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. Explain what would happen to the national income equilibrium if the investment changes by RM100 million.After government is added to the income-expenditure model, the formula for the aggregate consumption function is Group of answer choices C = a - b(T - Y). C = a + b(Y + T). C = a - b(Y - T). C = a + b(Y - T).Answer the question on the basis of the following table for a particular country in which C is consumption expenditures, Ig is gross investment expenditures, G is government expenditures, X is exports, and M is imports. All figures are in billions of dollars. Each question is independent of other question using the same table, unless otherwise stated.
