Suppose that the economy is characterised by the following behavioural equations: C = 160 + 0.6YD I = 150 G = 150 T = 100 Solve for a. Equilibrium GDP (Y) b. Disposable income (YD) c. Consumption spending (C) 3. For the economy in problem 2, a. Solve for equilibrium output. Calculate total demand. Is it equal to production? Explain. b. Assume that G is now equal to 110. Solve for equilibrium output. Calculate total demand. Is it equal to production? Explain. c. Assume that G is equal to 110, so output is given by your answer to (b). Calculate private plus public saving. Is it equal to investment? Explain.
