Assume that no banks hold excess reserves and the public holds no currency (which implies that ER = C = 0). If a bank sells a $100,000 security to the FED, explain what happens to this bank (Bank A) and two additional steps (or two additional banks, Bank B and Bank C) in the deposit expansion process assuming a 10% reserve requirement.Put differently, what will be the change in deposits for the first bank (D_A), the second bank (D_B), and the third bank (D_C)?
