SECTION 2
Answer all questions in the examination booklet.
Question I (15 points)
Consider a two period closed-economy model from Chapter 9.
a) (5 points) State the Ricardian equivalence theorem.
b) (5 points) Explain one possible reason why the Ricardian equivalence theorem may not hold in practice.
c) (5 points) Suppose that in the competitive equilibrium of the model, the current aggregate tax T=200, current aggregate consumption C=3000, and private saving is 95. Using the equilibrium conditions of the model, find the implied values of government debt B (the amount of government bonds issued) and aggregate income in the current period Y.
