Pearson Education Canada Inc.A bank cannot safely make loans for an amount greater than the excess reserves it has before it makes the loan.The final T-account of the First Bank (after the reserves have been withdrawn)is:First BankAssets LiabilitiesSecurities$100Loans+$10013 2005 Pearson Education Canada Inc.Deposit Creation:Banking System(r=10%)Bank AAssets

bank chooses to use its ER to make loans or to buy securities,the effect on deposit expansion is the same.17 2005 Pearson Education Canada Inc.Simple Deposit MultiplierSimple Deposit Multiplier1D=RrDeriving the formulaR=RR=r D1D=Rr1D=Rr18 2005 Pearson Education Canada Inc.Multiple Deposit ContractionThe multiple deposit creation process should also work in reverse.When the Bank of Canada withdraws reserves from the banking system,there should be a multiple contraction of deposits.In fact,the contraction in deposits will be D=(1/r)RExample:If R=-100 and(1/r)=10 because r=.10,then D =-1000.19 2005 Pearson Education Canada Inc.Multiple Deposit Contraction:The Banking SystemBanking SystemAssets LiabilitiesSecurities+$100Deposits-$1000Reserves-$100Loans-$100020 2005 Pearson Education Canada Inc.Critique of the Simple ModelOur simple model seems to indicate that the Bank of Canada has complete control over D.It ignores,however,the fact that deposit creation stops if:1.Proceeds from loan are kept in cash(in this case nothing is deposited in Bank B,and the deposit creation process stops).In this case D =100,not 1000 we calculated earlier.2.Banks hold more reserves.If Bank A decides to hold on to all$90 of ER,no deposits would be made to Bank B,and this would also stop the deposit creation process.Again,in this case D =100,not 1000 we calculated earlier.21 2005 Pearson Education Canada Inc.ConclusionThe Bank of Canada is not the only player whose behavior influences D and M.D and M depend on:1.the publics decisions regarding how much C to hold 2.the banks decisions regarding the amount of R they wish to hold,and3.borrowers decisions on how much to borrow from banks.22 2005 Pearson Education Canada Inc.
