higher than + V
Kemp apparel's second quarter growth rate was higher than [ anticipated ].
i am so confused. why it isn't [ anticipation] or [ anticipating ]?
than is a preposition, isn't it? Verb after preposition should be changed to Ving, right?
or
Kemp apparel's second quarter growth rate was higher than I or we [ anticipated ].
makes more sense.
why the subject is omitted?

Answer

我想如果把anticipate 换成expect 你可能就不会问这个问题了， 你肯定不会用expecting, 举个例子说明为何省略主语
Everything Went Better Than Expected 这里谁expect可能从上下文你肯定会知道，但此时没必要放主语，中文我们也是这样说的，一切比预想的要好，谁预想？从上下文自然可以找到

Answer

I think this is an impersonal construction - "higher than it was anticipated." 
It can be used if you are talking about some collective opinion, like "The new Avengers movie was better than anticipated" i.e. by the public or by the critics.

"Higher than I/we anticipated" is perfectly correct if you are talking about your own or somebody else's expectations.
