At least the existing 2% inflation target stands for something, because central bankers can portray it as the moral equivalent of zero. (Most experts believe that a true welfare-based price index would show significantly lower inflation than government inflation statistics indicate, because official data fail to capture the benefits of the constant flow of new goods into the economy.)
考虑到可能引起公众的迷惑和不信任，因此4%的通胀目标没有任何令人信服的理由。至少2%的通胀目标还有点道理可言，因为央行行长可以说它已经相当接近于零。（大部分专家认为，真正的基于福利的价格指数所表现的通胀将大大低于政府通胀数据，因为官方数据不能体现新产品源源不断进入经济带来的好处。）
