比如这一题
3.一个经济有l000张面值1美元的钞票这么多基础货币。计算情形a至d的货币供给,然后回答问题e。
c.所有货币都作为活期存款持有。银行持有20%的存款作为准备金。
对于问题c 圣才版的答案是:c.根据题意,得:C=0D=1000(美元)rr=20%cr=0R=Drr则R=1000*20%=200(美元)根据 ,B=C+R,得M=1000(美元)。
而英文版的答案是: c. If all money is held as deposits and banks hold 20 percent of deposits on reserve, then the reserve–deposit ratio is 0.20. The currency–deposit ratio is 0, and the money multiplier will be 1/0.2, or 5. The money supply will be $5,000.
大家觉得应该以哪个为准?
