Economists in Funlandia, a closed economy, have collected the following information about the economy for a particular year: Y = 10,000 C = 6,000 T = 1,500 G = 1,700 The economists also estimate that the investment function is: I = 3,300 – 100 r, Where r is the country’s real interest rate, expressed as a percentage. Calculate private saving, public saving, national saving, investment, and the equilibrium real interest rate.

Complete the following table by calculating private saving, public saving, national saving, investment, and the equilibrium real interest rate. Component Amount Private Saving Public Saving National Saving Investment Equilibrium Real Interest Ratearrow_forwardSuppose the real interest rate is higher than the equilibrium interest rate. We can predict that a. The real interest rate will decrease to encourage investment and discourage saving b. The real interest rate will increase to discourage investment and encourage saving c. The real interest rate will decrease to discourage investment and encourage saving d. The real interest rate will increase to encourage investment and discourage savingarrow_forward
- The graph shows the output function, savings function, and depreciation function for an economy. Show what happens when the investment rate decreases by half by shifting the appropriate curve or curves in the graph.arrow_forwardAssume that in this economy consumption (C) is given by the equation C = 600 + 0.6(Y – T). Investment (I) is given by the equation I = 2,000 – 100r, where r is the real rate of interest in percent terms. Taxes (T) are 500 and government spending (G) is also 500. What are the values of private saving, public saving, and national saving?arrow_forwardSuppose that the government creates a disincentive for private saving by increasing the tax that people pay on income from holding stocks and bonds. Construct a well-labeled diagram that depicts the effect of the policy change on the real interest rate and the equilibrium quantity of investment.arrow_forward
