First National holds only 10% as reserves and loans the rest to Billy. First National holds only 10% as reserves and loans the rest to Billy. Billy buys a snow blower for $900 from Carl.

Second National loans how much to Deyna if it also holds 10% as reserves? Second National loans how much to Deyna if it also holds 10% as reserves?

13. Creation of Money If this process goes on for thirty rounds, how much checking deposits will be in the banking system? If this process goes on for thirty rounds, how much checking deposits will be in the banking system? 1000 + 1000(.9) + 1000(.9)(.9)+…+1000(.9)^ 30 1000 + 1000(.9) + 1000(.9)(.9)+…+1000(.9)^ 30 1000 + 900 + 810 + … + 0.04 1000 + 900 + 810 + … + 0.04 1000 [1/(1-.9)] = 1000 [1/.1] = 1000 [10] 1000 [1/(1-.9)] = 1000 [1/.1] = 1000 [10]

27. Long Run Inflation In the long-run, the economy will operate at full-employment; so Y will not change if there is no growth. If there is growth, then Y is predictable: Y is known. In the long-run, the economy will operate at full-employment; so Y will not change if there is no growth. If there is growth, then Y is predictable: Y is known. Velocity is also thought predictable in the long-run. Velocity is also thought predictable in the long-run. Therefore, any growth in money supply will be reflected in inflation. Therefore, any growth in money supply will be reflected in inflation.
