首先恭喜绿军波士顿凯尔特人干爆雄鹿，下一步VS热火会看到布朗大战铁血巴特勒(我的挚爱)！顺便吐槽下德文布克空位三分不稳，我已经卖了换的历史步行者穆林。14.2.1 Multiple Deposit ExpansionHow a Single Bank Responds to an Increase in Reserves: Suppose that the Fed purchases $100,000 in Treasury bills (or T-bills) from Wells Fargo, increasing Wells Fargo’s reserves by $100,000.Suppose that Wells Fargo loans $100,000 to Rosie’s Bakery to enable it to buy two new ovens. We will assume that Wells Fargo makes the loan by creating a checking account for Rosie’s and depositing the $100,000 principal of the loan in it. Both the asset and liability sides of Wells Fargo’s balance sheet increase by $100,000:Recall that the money supply—using the M1 definition—equals currency + checkable deposits. By lending money to Rosie’s, Wells Fargo creates checkable deposits and, therefore, increases the money supply. Suppose that Rosie’s then spends the loan proceeds by writing a check for $100,000 to buy ovens from Bob’s Bakery Equipment. Bob’s deposits the check in its account with PNC Bank. Once the check has cleared and PNC Bank has collected the funds from Wells Fargo, Wells Fargo will have lost $100,000 of reserves and checkable deposits:Wells Fargo is now satisfied because it has exchanged some of its low-interest Treasury bill holdings for a higher-interest loan. But the effect of the open market purchase on the banking system is not finished.How the Banking System Responds to an Increase in Reserves:After PNC has cleared the check and collected the funds from Wells Fargo, PNC’s balance sheet changes as follows:If the required reserve ratio is 10%, PNC must hold 10,000 (= 0.10 * 100,000) against its increase of $100,000 in checkable deposits. The other $90,000 of the reserves it has gained are excess reserves.Suppose that PNC makes a $90,000 loan to Santiago’s Printing to purchase new office equipment.Simple deposit multiplier : The ratio of the amount of deposits created by banks to the amount of new reserves.}
