在ISLM model入面
人只會hold 兩種assets
bond and money
bond price(P) , bond income(Y) 同 interest rate(r) 的 relationship,
P=Y/r
givenY,如果r上升,P會下降
so , they will suffer loss if they hold bonds
當人們相信這一個利率水平已經是最低的極限
r will expected to increase -> suffer loss when holding bonds
so they will hold infinite money(money for asset) instead of bonds
貨幣需求的利率彈性=interest eleasity of money demand (e)
liquidity trap => 貨幣需求的利率彈性係無限
人們不是不再受利率影響了嗎?
不
當利率上升,people will decrease their 貨幣需求(money demand for assets)
因為expect利率下降 -> gain form holding bond

其實唔係ISLM model有liquidity trap 都係assume人hold bond or money
