- Determine equilibrium levels of income and consumption for the following functions.a.C=20+0.75y,I=20,b.C=50+0.60y,I=30. WhereC&I are consumption and investment respectively in billions of nairaAssuming that each of the following functions are linear, give an economic interpretation of the slope ofthe function:a. C(Y) is the national consumption when national income is Yb. S(Y) is the total national savings when national income is YConsider the Savings-Investment model involving: The Savings function: S = S0+s1Y+s2r; and the Investment function: I = I0+ir; where: Y = GDP, r = interest rate; and equilibrium occurs when Savings equal Investment. (i) Solve for the equilibrium GDP Y* (ii) Using your Y*, find the Investment-Multiplier dY*/dI0
- Find the equilibrium level of GDP (income or V) demanded in an economy in which investment (1) is always $300, net exports (X-IM) are always - 550, government expenditures (G) and taxes (T) are each equal to $400, and the consumption function is described by the following algebraic equation: C = 150 + 0.75Dl DI is disposable income. How much saving (5) is there at the equilibrium level of income. Hint: (1) Dl = Y (national income or GDP) minus taxes (Y-T) (2) Income (Y) not consumed (C) must be saved (S). This means that S = Y-C. (3) to answer this you have to set Y=AE or Y=C+1+G (X-IM), and solve for Y. Then you have to solve for S.The 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 functions for consumption and investment: C = 1,000 + (2/3)*(Y – T) and I = 1,200 – 100*r. Furthermore, Y = 8,000, G = 2500, T = 2,000. Compute private, public, and national savings for this economy, and find the equilibrium real interest rate (r). Assume that G declines by 500 units. How will it change your answers in part (a)? What happens to the national savings, given everything else, if the public decides to consume less out of their disposable income (assume that the propensity of consume falls by 10 percent)? Given your answer in part (c), what happens to investment and real interest rate? Answer all four.
- Due to some negative news concerning the impact of global warming on the economy, consumers are becoming more pessimistic about the future to the point of reducing autonomous consumption by 50. What is the immediate impact on income before the economy adjusts to its new equilibrium? What are the economy’s equilibrium level of output Y and interest rate r following the fall in autonomous consumption? Compute the equilibrium level of consumption and investment spending. With the help of the IS/LM graph, carefully explain what happens to the economy following the fall in consumer confidence.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.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.
- If U.S. consumers become more optimistic about their future income and wealth, the consumption function will shift upward. True or FalseGiven consumption function C = 0.6Y + 35 1) Find the equilibrium level of income Y for the planned investment l = 12 ? 2)Find the equilibrium level of consumptionRequired information Skip to question Assume that the parameters of a particular economy are as follows (all figures are in $billions):C = 100 + 0.75Y I = 50 Refer to the above information to answer this question. If investment were to increase by $25, then what would happen to equilibrium income? Multiple Choice It would increase by $100. It would decrease by $100. It would increase by $25. It would increase by $18.75. It would decrease by $18.75.
