Problem Set 4: Saving and Investment
Economists in Fantasialand, a closed economy, have collected the following information about the economy for a particular year: Y = 9000; C = 6000; T = 1500; G = 1700. The economists also estimate that the investment function is: I = 3300 - 100r, where r is the country’s real interest rate, expressed as a percentage (i.e. r = 1 means interest rate is one percent). Calculate private saving, public saving, national saving, investment, and the equilibrium real interest rate.
Explain how changes in interest rates and rates of return on various investment options will affect the amount of money that businesses are willing to invest to increase output.
If Net Investment = 0 in a given year, this indicates that we have neither lost nor gained capital. That seems to be a desirable outcome. Do you agree?
