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 interes 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.

You observe a closed economy that has a government deficit and positive investment. Which of the following is correct? Select one: O a. Private saving is negative; public saving is positive. O b. Both private saving and public saving are negative. O . Private saving is positive; public saving is negative. O d. Private and public saving are both positive.
Suppose that conditions in the economy are such that the after-tax expected real interest rate is described by the equationRa = a X gWhere a is a number that depends on how people value their consumption in one period compared with another period, and g is the growth rate of the economy. The a equals 1 when people prefer consumption to be balanced, with the same amount of consumption each period; a may be bigger than the one when people prefer consumption today over consumption in the future, with a being larger and larger the more impatient people are:A - Suppose that a = 2, g = 0.02, the inflation rate is expected to be steady at pi = 0.03, and the tax rate is .40. What are the values of the equilibrium nominal interest rate and the before-tax expected real interest rate?B - Beginning with the situation in part a, if the growth rate of the economy increases to .04, what are the new values of the equilibrium nominal interest rate and the before-tax expected real interest rate?C-…
