A) Assuming the tax function now consist of autonomous and a proportional taxes and the following two additional conditions hold: Closed Economy (NX= 0) Prices are fixed Derive the values of Y* and i* that satisfies equilibrium conditions in both the goods and money markets simultaneously. B) Given the following assumptions: Tax function is given as T = TO + tlY Net imports is given as NX = X - MM = MO + m1 Y and X = X0 Price is fixed. 1. Solve for Y* and i* 2. Analyse the multiplier for Y* 3. If there is a change in foreign imports by 1%, what will be the impact on the domestic interest rate? Give the numerical magnitude of the impact for the given values of MPC = 0.8, MPI = 0.3, MTR = 0.3, elasticity of investment with respect to the interest rate = 0.2, elasticity of money demand with respect to income = 0.5, and elasticity of money demand with respect to interest rate = 0.2.
