派生存款发生实例 Imagine a system with just three commercial banks, A, B and C, whose balance sheets are shown below. Bank A Bank B Bank C A L A L A L C= 20 D= 1600 C= 20 D= 1600 C= 20 D= 1600 bPbPbP D= 60 D= 60 D= 60 b b b B= 1520 B= 1520 B= 1520 L LL where D are customers' deposits, C is cash (notes and coin) held by banks, pb D are banks" deposits at the central bank and BL are loans to the non-bank bp public. Bank reserves, R, consist of C + Dand a bank's reserve ratio is thus bb R/D. Assume that non-banks hold 800 in notes and coin (C). pp (1) What is the size of the money stock, C + D? pp (2) Calculate the reserve ratio, R/D, for each bank and for the system as a p whole. Suppose now that bank A increases its loans (BL) by 10 and that its p customers use this lending to pay 5 to clients of bank B and 5 to clients of bank C. (3) Show the new balance sheet position for each bank. (4) By how much has the money supply increased? (5) Calculate the new reserve ratio for each individual bank and the aggregate reserve ratio. Suppose now that bank B also increases its lending by 10 and that its customers use this lending to pay 5 to clients of banks A and C, and that bank C increases its lending by 10 and that its customers use this lending to pay 5 to clients of banks A and B. (6) What is the size of the money stock now? (7) What is the reserve ratio for each bank? (8) What is the aggregate reserve ratio? (9) What quantity of bank deposits are customers of each bank now holding? Suppose that customers of each bank now decide to increase their holdings of notes and coin (C) by 5. p (10) What effect does this have on the total money supply? (11) What effect does this have on the composition of the money supply? (12) What effect does this have on the aggregate reserve ratio? 隐藏
