This article introduces a new online simulation game called Cash Beer Game, which is an augmented version of the standard Beer Game by including cash flows. In addition to the inventory ordering and shipping activities, each player pays cash for the ordered inventory to her upstream partner and receives cash from her downstream partner. The goal of this game is to explain the interactions between material, information, and financial flows in a supply chain and help students understand the impact of financial flows on the inventory decision. The resulting bullwhip effect can be compared between teams and with that of the standard Beer Game for the same team.
