4. Consider the following money demand function: \frac{M}{P} = Y \times \frac{\alpha}{\pi} Here, $\pi$ is the inflation rate and $\alpha$ is a parameter. a. Explain the intuition for such a money demand function. b. Suppose the government does not know how to collect conventional taxes and relies completely on seigniorage revenues. Suppose that output is constant at Y = 1 at the steady state. Show the formula for steady state seigniorage revenue. \"Steady state\" here means that output and inflation are constant. c. Can the government increase seigniorage revenue by increasing the inflation rate in this example? Explain intuitively why or why not. d. Now suppose that high inflation makes economy deteriorate, so that steady state output depends negatively on $\pi$. What will happen to the seigniorage revenue if inflation rate increases in this case?

Suppose a country has a money demand function (M/P) = kY, where k is a constant parameter. The money supply grows by 12 percent per year, and real income grows by 4 percent per year. a. What is the average inflation rate? b. How would inflation be different if real income growth were higher? Explain c. How do you interpret the parameter k? What is its relationship to the velocity of money? Suppose, instead of a constant money demand function, the velocity of money in this economy was growing steadily because of financial innovation. How would that affect the inflation rate? Explain.

Suppose that the money demand function takes the form: (M/P)^d = L(i,Y) = Y/10i. (a) Provide economic intuition on the functional form of the real money demand function. (b) If output grows at a rate g and the nominal interest rate is constant, at what rate will the demand for real balances grow? (c) What is the velocity of money in this economy? (d) If inflation and nominal interest rates are constant, what rate will velocity grow? (e) If the central bank wants to achieve a long-run target inflation rate of π, at what rate should the money supply grow?

Suppose that the money demand function takes the form (M P )d = L(i, Y ) = Y 200i where M is the nominal amount of money in circulation, P is the price level, Y is real output, i is the nominal interest rate, and L(i, Y ) is the demand for real money balances. (a) If output (Y ) grows at rate g = 3%, at what rate will the demand for real money balances grow (assuming constant nominal interest rates)? (b) What is the velocity of money (V ) in this economy, if the nominal interest rate is i = 4%? (c) If nominal interest rates are constant, at what rate, if any, will velocity (V ) grow? (d) Suppose that there is a permanent (once-and-for-all) increase in the interest rate to i = 5%, What is the velocity of money (V ) after the increase in i? (e) Suppose that the nominal interest (i) is constant, output (Y ) grows at rate g = 3%, and the nominal money supply (M ) grows at rate 5%, then what is the inflation rate (π)? (The interpretation of variables given as percentages are such that if, for example, the interest rate is 1%, then i = 0.01.)
