Layers and mechanisms: A new taxonomy for the Bullwhip Effect Giovanni Miragliotta In this article‚ Giovanni Miragliotta has two main purposes. The first one is to strengthen the knowledge on the dynamics of a supply chain via a deep review of the Bullwhip Effect. The second one is to build a new framework abled to classify the causes of the Bullwhip effect. Furthermore‚ this framework can distinguish layers and mechanisms that lead to Bullwhip Effect and so help managers to better understand
