为何重要

the Federal Reserve watches these measures to judge whether inflation is broad-based. When they agree with the headline, the trend is real; when they diverge, a few items are distorting the picture.

计算方法

A trimmed mean removes the items with the largest and smallest price changes (for example the top and bottom 15% by weight) and averages the rest; a weighted median takes the price change in the middle of the distribution. Other variants hold mortgage interest costs fixed or use common components.

变化意味着什么

• A trimmed mean or median near the target is the clearest sign that inflation is under control.
• When the headline jumps but these do not, the move is likely temporary.

简史

Trimmed means were developed in the 1990s (Bryan and Cecchetti at the Cleveland Fed); the Reserve Bank of Australia and the Bank of Canada give them a central place in their policy.
