Consider the following economy, which is the same economy as the one presented in class: Aggregate Expenditure E, = C, + 1, + G, + X, - M, Consumption C = ac + b,Y, Investment I, = a; - b R, Inflation Government Expenditure and Trade G, = G, M, = M, X, = X Suppose that this economy is at its long-run equilibrium, with o, = 0 and r, = 0.06. Assume that the government wants to decrease the level of inflation to n,,3 = 0.03. To do that they decided to use fiscal policy (G) to reduce a by 0.01 each year for three years. Using the full short-run model (IS-MP and Phillips curve), explain what happens to the economy over time. Be sure to include graphs showing: i. the IS-MP, ii. the Phillips Curve, and ii. how deviations from potential output and the level of inflation respond over time. Carefully label all graphs (including the level of potential output as a function of parameters and the change in inflation in each period).
