Now, consider an economy in which the demand for money is of the formY / (1 + it) for t = 0, 1, 2, · · · , where output is 150 and it denotes the nominal interest rate inperiod t. The real interest rate, denoted r, is constant and equal to 4%. In period0 and 1, the money supply is 100 and people expect that money supply wouldbe 100 forever. People have rational expectations. In period 2, the central banksurprises people and sets the money supply will grow at 2 percent forever, that is,M0 = 100, M1 = 100, M2 = (1.02)M1, M3 = (1.02)M2, and so on. A . Find the inflation rate, nominal interest rate, real money balance in period 1,and expected inflation in period 2, given the information available in period1, π1, i1, M1 / P1 and, E1π2. B . Find the inflation rate, nominal interest rate, real money balance in period 2, and expected inflation in period 3, given the information available in period 2, π2, i2, M2 / P2 and E2π3. C . Compare E1π2 and π2.

1-)What is the difference between a real rate and a nominal rate? Say you got a raise of 10% of your salary but inflation increased by 15%, what is your real percent increase in salary? How should we use this in every day life to make changes that will make us wealthier over time. 2-) How can we use the Aggregate Supply and Demand Model to help us understand what the government is doing in the current Covid19 economic crisis? 3-) What is the basic difference between Fiscal and Monetary Policy, how are they used during recessions? 4-)
