EMLyon has a well known tradition of Entepreneurship research and a number of big shots: Philippe Monin (AMJ, AJS, ASR, SMJ... evidence for doingfine that there are researchers outside the US who publish in top US journals), or among the young guns, Ignasi Marti (AMJ, JBV, etc MARTI Ignasi - EMLYON Business School).
Although it got distanced by other schools, EMLyon's focus on research is pretty much in their DNA. It was on the first school in Europe to engage into research, way before ESSEC.
