Here is a recent paper, reported to us by Professor Ramandeep S. Randhawa that describes how the Academic Job Market works in Economics (at least in the US):
A Guide and Advice for Economists on the U.S. Junior Academic Job Market: 2014-2015 Edition, by John Cawley.
If you did find that useful and relevant, please encourage the recently hired Assistant Professors in Operations (broadly defined) of your Institution to answer our (anonymous) Annual Job Market Survey and share their Job Market experience with us (was it efficient? how many papers did an average Candidate had and in what stage? what can we do better to help all parties perform the necessary matching? etc). Provided there are enough data collected we will try to publish a report of our findings on the upcoming INFORMS Annual Meeting in San Francisco. (there are indeed at least 25 verified individuals who have already fully answered our Survey so far...)
