One such friend, Economics Professor Jerry R. Green, has been in touch with Maskin ever since Green taught a seminar that Maskin enrolled in as a senior at the College.

“He was not only a strong researcher and a dedicated teacher, but a great servant of the University,” Green said of Maskin’s previous tenure at Harvard. “He is everything a faculty member should be.”

CORRECTION: OCTOBER 26, 2011

The Oct. 25 article "Economics Nobel Laureate Eric Maskin Returning to Harvard" incorrectly stated that the Institute for Advanced Study is closely affiliated with Princeton University. In fact, though the Institute "enjoys close, collaborative ties with Princeton," according to its website, the Institute has no formal affiliation with any other educational institution.
