Romain Cadario


I am currently Assistant Professor at Erasmus University, Rotterdam School of Management. My research in behavioral change has been featured in Nature Human Behaviour and Marketing Science, among others.


My research develops and evaluates marketing interventions designed to stimulate societally desirable consumer behaviors. My research incorporates mixed methods from laboratory, online experiments to analyses of secondary data with econometric and meta-analytical techniques.

I am passionate about teaching and I have acquired a rich experience by teaching a variety of classes from undergraduate to doctoral level, such as: marketing principles, marketing research, digital marketing analytics, marketing engineering, behavioral change, and statistics. I conducted doctoral workshops on moderation & mediation analyses based on my textbook (in French).
