4. Consider the economy is characterised by the following equations: C = co + C1YD T = to + tY t1 E (0,1) Y, = Y – T G and I are both constant. (a) Find the multiplier. (b) Does the economy respond more to changes in autonomous consumption (co), when ti is zero or positive? Explain your answer. (c) Now assume that taxes are lump sum (constant, i.e., T = T), but investment increases with output through the equation I = bo + bịY, what is the new multiplier? (d) Suppose that the parameter bo increases. If we call this parameter the "business confidence", how will equilibrium output be affected by increasing the business confidence? Will total savings go up by this change? Explain your answer.

Question 2 Refer to the information provided in Figure 23.9 below to answer the question(s) that follow. Aggregate expenditures ($ millions) 225 200 175 150 45° AE 100 200 300 Aggregate output ($ millions) Figure 23.9 a) Refer to Figure 23.9. Write the equation for the aggregate expenditure function (AE). Show your work. b) Refer to Figure 23.9. What is the equilibrium level of output in this economy? State the equilibrium condition used to determine this. c) Explain the forces that maintain/drive the economy to this equilibrium by considering what will happen at the following two levels of output, $300 million and $100 million. You will need to discuss changes in investment through unplanned inventories and the response of output. d) Refer to Figure 23.9. How will equilibrium aggregate expenditure and equilibrium aggregate output change as a result of a decrease in investment by $20 million? e)The interest rate is an exogenous factor that effects the level of investment in an economy.…

4. Planned expenditure and income The following table shows consumption (C), investment spending (I), and government purchases (G), in a hypothetical economy for various levels of income. Also assume that there is an income tax rate of 25%, that base consumption is $100 billion, and that the MPC is 0.333, or 1/3. This economy is closed, with no international trade, therefore net exports are equal to zero and should not be considered. Use the given information to fill in disposable income, consumption, and planned expenditures in the following table. Income: Real Disposable (After Tax) Planned GDP Income C I, G Expenditures (Billions of (Billions of dollars) (Billions of (Billions of (Billions of (Billions of dollars) dollars) dollars) dollars) dollars) 100 50 150 100 50 150 200 50 150 300 50 150 400 50 150 500 50 150
