Given the following informations; Consumption(C) 800+0.9Y, Where Y-Income Investment (I) =8000-800r, where r=interest rate Money Supply (Ms) =28500 Demand for Money (Md) =0.75Y-1500r and if the autonomous Investment decreased then income decreased and interest rate increased. income increased and interest rate decreased. O income decreased and interest rate decreased income increased and interest rate increased

QUESTION 2 Consider the closed-economy market-clearing model. Assume that the marginal propensity to consume is 0.8. Tax revenue decreases by $5 billion, while output and government spending remain the same (a) Calculate the dollar change in consumption. (b) Calculate the dollar change in national saving. (c) Does the equilibrium real interest rate increase, decrease, or stay the same? n toolhar nress ALT+F10 (PC) or ALT+FN+F10 (Mac).

Assume there are no investment projects in the economy that yield an expected rate of return of 25 percent or more. But suppose there are $10 billion of investment projects yielding expected returns of between 20 and 25 percent; another $10 billion yielding between 15 and 20 percent; another $10 billion yielding between 10 and 15 percent; and so forth. a. Cumulate these data and present them graphically using the graph below, putting the expected rate of return (and the real interest rate) on the vertical axis and the amount of investment on the horizontal axis. Instructions: Use the tool provided 'ID' to plot the investment demand curve (plot 6 points total). 30 Tools ID 20 15 10 10 20 30 40 50 60 Investment (billions of dollars) Instructions: Enter your answers as a whole number. b. What will be the equilibrium level of aggregate investment if the real interest rate is: 15 percent: $ billion 10 percent: $ billion 5 percent: $ billion Expected rate of return, percent 25
