They think a spending spree by grey consumers, fuelled by government handouts to the old, could drive up the neutral rate of interest.

他们认为，银发消费者的支出增加，再加上政府向老年人发放养老金的推动，可能会使中性利率上升。

The neutral rate of interest can be more strictly defined as the rate of interest which prevails in equilibrium when output and employment are such that the elasticity of employment as a whole is zero.

中性利率可以更严格地定义为当产出和就业使得整个就业的弹性为零时处于均衡状态的利率。
