RePEc citation profiles now tell you who are the ten authors who cite your work the most and who are the ten authors you cite the most. At least, I don't remember seeing this feature before. Pretty predictably the authors citing me the most are working on issues around the environmental Kuznets curve and energy-GDP causality. The authors I have cited the most are EKC researchers and econometricians. I'm a bit surprised that Peter Phillips is the econometrician I have cited the most. Would have thought Clive Granger would have gotten more cites from me.
