The real interest rate r is fixed at 3 percent by the investment and saving functions. The expected inflation rate equals the rate of nominal money growth.
(a) If Y is 1,000, M is 100, and the growth rate of nominal money is 1 percent, what must i and P be?
(b) Identify d(M/P)/di. What does this mean?
