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?

NEW QUESTION Consider the investment function of the IS model. Suppose that in the long-run 20% of GDP is spent on investment. Moreover, a one percentage-point increase of the real interest rate reduces the share of investment in GDP by one percentage point. Suppose that at some time t the real interest rate is equal to -1% while the rate of return of physical capital (think of it as the marginal product of capital) is 3%. What is the share of investment in GDP at time t?

Hi please

Suppose the government must increase taxes in order to increase spending.  Now assume Congress wants to increase spending on education without decreasing spending somewhere else.    For each variable state if it will INCREASE, DECREASE or REMAIN UNCHANGED.   In at least one complete sentence state WHY this change will occur.  Be specific.   Private Saving (Sp): Consumption: (C) Government Saving (Sg) Total Saving: (S) Real Interest Rates: (r) Investment: (I)
