Check out the departmental rankings at econphd.net:
The econphd.net rankings are among the most substantial in scope (covering 63 journals over roughly ten years, 1993-2003) and they are unique in detail (the only consistent rankings at the subdiscipline level). Detail is very important: I cannot think of anyone other than a dean or head of department who should really care about a department's overall ranking. It is hoped that these rankings are particularly useful to prospective PhD applicants. They should also help publicize specialized expertise at smaller departments. Journal selection and quality-adjustment are based on the citation analysis by Kalaitzidakis et al.
According to the "network analysis," my preferred ranking, The Ohio State University is ranked 10th in the world and The Appalachian State University is ranked 80th (out of 192) in resource and agricultural economics. Thank goodness for our productive co-authors.
