Along with business schools, Economics is where pedigree matters most in the placement of PhD students to academic positions. Students from top ranked (or considered such) programs have a job almost guaranteed in research universities, and students from lower ranked universities find it very hard to break into such universities no matter what their performance is. In part, this is due to the fact that we tend to hire faculty fresh out of graduate school, while other fields go first through post-docs, and that publication delays imply that graduating students have typically no publication. Thus one has to rely on reputations only (or actually read their papers, but then are you going to read the papers of all students from lower ranked programs?).
John Conley and Ali Sina Onder find that while there is indeed a steep gradient across program rankings, there is an even steeper gradient within programs. They use student rankings within programs and cohorts and their publication output after six years, that is, when they are up for tenure. Looking at AER equivalents, they find that the top Toronto student is equivalent to the number three from Berkeley, for example. And to illustrate how steep the gradient is, the median Harvard student has after six years only 0.04 AER equivalent publications, despite coming from the #2 program. This means that more than half of Harvard students are not tenurable in any research-oriented institution.
I see two major conclusions from this: 1) Stop worrying so much about where PhD students are graduating from. It is OK to hire students from lower ranked programs as long as they excelled in those programs. 2) Even the top places should acknowledge that not all students should take research positions and need to prepare them for other ones, like industry, government or purely teaching jobs. These students are screwed twice: they are sent to tenure-track positions that they will never get tenure in, and they are woefully unprepared for the jobs they should take.
