Sentence Correction

I was taught that "consider to be" is always wrong. Then I found the following sentence, (which is supposedly correct):

"Considered to be one of the brightest economists, Paul Krugman has written countless articles on economic and monetary policy; his writings, which include contributions to Harvard Business Review, is cited more often than those of most other economists today."

Is there an exception to the "to be" rule going with the word consider if the perfect tense is used? If so, is this true for past, present and future? If there is such an exception, does it apply to other verbs as well? Please advise. Thanks!
