The government buys $1000 worth of bonds from the commercial banks:
Reserves + 1000
Investment - 1000

New Deposit->(2500+1000)x(1/(2500/10000))= 14000
Thus, money supply is 14000
Excess reserve->3500-14000x0.2=700

咁正式黎講, 究竟$1000 bonds係扣investment $1000, 定係係credit side加$1000?

回覆 4# mc0011 的帖子

sorry 我估題目個bonds應該係government bonds under Open market operations
所以係扣investmetns
但據學校老師所講 dse唔會特登考investments 當investments入晒loan
多數係gov向public sell buy bonds
