PAST PAPER

Along on Lm curve,

A national income is constant
B money supply is constant
C consumption expenditure is constant
D velocity of circulation of money is constant.
ans is B

點解d錯,along with LM,V應該不變

簡拿華路

唔識

但keynesian 的 ISLM model 有2個assumption
1) Money supply is constant
2) General Price Level is constant (Price is rigid until full employment is achieved.)

賣花明

係B 的原因, 簡拿華路 ans 左你 . 因為係Assumption.

而唔係D, 因為今條係考試局Yam你..
ISLM model "基本上" 係同PY=MV 無關.
PY=MV 係base on Money view 去睇個Econ ,
同圖係唔同學派 (一個係 Keynesian, 果一個Monetory), 基本上佢地唔會一齊出現
除非佢講明, or 你係做學術.... ..

因為完全無開, 所以根本無關..
以上係我的見解. 因為我一睇到B 就會Ans 左..
