What can price stability possibly mean in an era when new goods and services are constantly being introduced, and at a faster rate than ever before? US statisticians have tried to “fix” the consumer price index to account for new products, but many experts believe that measured US inflation is still at least one percentage point too high, and the margin of error can be more volatile than conventional CPI inflation itself.
甚至是通货膨胀也是难以精确衡量的。当新的产品和服务不断推陈出新、快于以往的时候，价格稳定意味这什么呢？美国统计人员曾经试图“确定”消费物价指数来统计新产品，但是许多专家相信计算出来的美国通货膨胀依旧高出一个百分点，而误差可能要比传统消费物价指数通胀本身更为起伏不定。
