Consider the money supply Ms=mxB , m=r+1 cr+rr Assume that the demand for real money is given by the equation (M/P)d%=0.25Y, and that the output has been growing 3% per year. Assume, further, that you have been called before Congress to testify about the long-run effects of increasing the growth of the money supply to 10 % per year. 1. State, compute and explain the long-run effects of this change on the inflation rate, on the nominal interest rate, on the real interest rate, on investment and on the real GDP. For each of them, argue both using the formulae that we studied and the macroeconomic dynamic beyond the effect.

Question
Exercise 1 cr+1 Consider the money supply Ms=mxB , m = cr+rr Assume that the demand for real money is given by the equation (M/P)d=0.25Y, and that the output has been growing 3% per year. Assume, further, that you have been called before Congress to testify about the long-run effects of increasing the growth of the money supply to 10 % per year. 1. State, compute and explain the long-run effects of this change on the inflation rate, on the nominal interest rate, on the real interest rate, on investment and on the real GDP. For each of them, argue both using the formulae that we studied and the macroeconomic dynamic beyond the effect. 2. Compute the implied money velocity. Suppose that the actual nominal value of the output (PY) is 1000, the value of the reserves is 50 and the toal value of the deposits is 75. Find the actual money multiplier. 3. State the different ways in which the central bank can achieve the change (+10%) in the money supply (think about the variables that can affects Ms), arguing about the pros and cons of each one. Which one do you think is better and why?
