- Assume a consumption function that takes on the following algebraic form: C = 100 + 0.8 Y. Assume that Y= 1450 what is the level of consumption at this income level.Linear equations for the consumption and saving schedules take the general form C = a + bY and S = -a + (1 - b)Y, where C, S, and Y are consumption, saving, and national income, respectively. The constant a represents the vertical intercept, and b represents the slope of the consumption schedule.a. Use the following data to substitute numerical values for a and b in the consumption and saving equations. b. What is the economic meaning of b? Of (1 - b)? c. Suppose that the amount of saving that occurs at each level of national income falls by $20 but that the values of b and (1 - b) remain unchanged. Restate the saving and consumption equations for the new numerical values, and cite a factor that might have caused the change.Determine equilibrium levels of income and consumption for the following functions. a.C=20+0.75y,I=20, b.C=50+0.60y and I=30.where C&I, are consumption and investment respectively in billions of naira
- Depict graphically the equilibrium level of National Product (NP) using the Aggregate Expenditure (AE) function. Explain why the intersection of the 45 degree line and the AE function represents equilibrium by appealing to the difference between actual and desired investmenLinear equations for the consumption, saving schedules take the general form C = a+ bY and S= -a + ( 1 - B) Y, where C, S , and Y are consumption, saving, and national income, respectively. The constant a represents the vertical intercept, and b represents the slope of the consumption schedule. A) use the following data to substitute numerical values for A and B in the consumption and savings equation  B) what is the economic meaning of B? Of (1-b)? C) suppose that the amount of saving that occurs of each level of national income falls by $20 but that the values of B and (1-b) remain unchanged. Restate the saving and consumption equations inserting the new numerical values, and cite a factor that might have caused the change.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.
- If U.S. consumers become more optimistic about their future income and wealth, the consumption function will shift upward. True or FalseIn an economy, as per the aggregate income identity : Y=C+I+G+X−M. Assuming the following relations exist and values given, show your working to compute the value of the multiplier: C=c0+c1(1−t)Y I=a0−a1r G=g0−g1Y X=x0 M= m0+m1Y c0=3.71, c1= 0.55, t= 0.78, a0= 4.83, a1= 0.57, g0= 9.31, g1= 0.05, x0= 2.46, m0= 6.19 and m1= 0.3The private consumption of Macroland is given by C=500+0.75Y and the private investment function is given by I=400−1000r, where r is the interest rate and Y is the GDP. The planned aggregate expenditure can therefore be written as PE=C+I=900+0.75Y−1000r. The equilibrium in the goods and services market happens when the planned expenditure is equal to the actual expenditure, or PE=Y Find the equilibrium GDP by solving the system of equations PE=900+0.75Y-1000r PE= Y for Y and PE. Note your solutions will depend on r! 1. Plot your solution for Y in a diagram measuring Y on the horizontal axis and r on the vertical axis. This curve is called the IS curve.
- Consider the following consumption function: C = 800 + 0.75 YD for the fictitious economy of Zapland. If the government increases transfer payments by $200 million what is the change in GDP? Assume that there is no increase in the price level. Select one: a. $300 million b. $500 million c. $600 million d. $400 million e. -$600 millionAssume 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. Calculate the national income equilibrium.The fundamental equations in an economy are given as: Consumption function C =200+0.8yd Investment function. I=300 Tax. T=120 Government expenditure.
