A liquidity trap can occur whenever there is a sharp reduction in demand for loanable funds-which is exactly what happened during the Great Depression.
只要对可贷资金的需求出现急剧下降,流动性陷阱就会发生——这正是大萧条期间所发生的事情。
In theory an economy is said to be in a liquidity trap when the monetary authority cannot achieve lower nominal interest rate in order to stimulate output [1].
在理论上,一个经济体被认为是在流动性陷阱时,货币当局不能实现较低的名义利率,以刺激输出。
However on the subject of how to escape from a liquidity trap there is no such consensus.
