Higher interest rates can spur consumption if their impact on income outweighs the increased incentive to save. This may well be the case for Japan, which has a rapidly aging population.
更高的利率可以刺激消费，如果对收入的增长超出了人们的储蓄欲望的话。这种情况很有可能会在日本发生，因为它是一个人口快速老龄化的国家。目前超低的利率会使人们担心未来是否有足够多的收入。提高利率可以减少这种担心，提高消费者的信心和消费。
