In this paper we analysed the relation between cooperativeness as a personality trait of participants in a supply chain and the bullwhip effect. We explored the possibility of change participants’ cooperativeness but we also showed the learning process of engineering students. In order to teach our students about behavioural causes of the bullwhip...
