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.
