4. Consider a classical economy described as follows: 11 Y = LZK², where L is the amount of labor and K is the amount of capital. The economy has 10,000 units of labor and 10,000 units of capital. Consumption (C): 5,020-100r, Investment (I): 2,000-100r, Taxes (T): 2,500, Government Purchases (G) :3,000 a. Compute the total production and find the equilibrium interest rate. b. Compute private saving, government saving, and national saving. c. Now suppose that G is reduced by 10. Find the new equilibrium interest rate. What happens to consumption, private saving, government saving, national saving and investment? 5. An economy has a monetary base of 100$ bills. People hold equal amounts of currency and demand deposits. Banks has 20% of deposits as reserves. a. What is the money multiplier? Compute the money supply. b. The central bank decides to increase the money supply by 10%. How much should it increase the monetary base?
