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.

M, is the speculative demand for money and r is the interest rate (in % points). a) Derive (m/P) the demand for real money balances equation (where P is the aggregate price level.) b) Derive the IS and LM equations of the economy (Express Y as a function of r and assume Pis fixed at 1.0.) c) Calculate the short-run equilibrium values of Y and r in the economy.arrow_forwardConsider an economy described by the following equations: Y = C+I+G Y = 5000 G = 1000 T = 1000 C = 250 + 0.75(Y-T) I = 1000 - 50r In this economy, compute private saving, public saving, and national saving. Find equilibrium interest rate. Now suppose that G rises to 1250. Compute private saving, public saving, and national saving. Find the new equilibrium interest rate. Using your knowledge of Macroeconomics and intuition explain the reason why increasing government expenditure causes interest rate to rise? If the government wants to increase the amount of savings in the economy, how should it alter government spending? What effect will this action have on the interest rate in the economy?arrow_forwardThe magazine Women of China reported that Chinese women in big cities spent 63% of their income on consumer goods last year, up from a meagre 26% in 2007. Clothing accounted for the biggest chunk of that spending, at nearly 30%, followed by digital products such as cellphones and cameras (11%) and travel (10%). Chinese consumption as a whole grew faster than the overall economy in the first half of the year and is expected to reach 42% of GDP by 2020, up from the current 36%.
