Abstract for: Individual Performance in the Beer Game: Underweighting the Supply Line and the Impact of Personality

Data was collected from undergraduate students playing an online version of the Beer Game and correlated with data from a personality survey. Several measures of individual performance were developed that loaded into 5 factors: anchoring, weighting of visible inventory, weighting of unseen inventory, inconsistency, and amplification. Results show that personality does predict some measures of performance in the beer game, and more so for the wholesaler and distributor role. A surprising result is that underweighting the supply line inventory is not correlated with demand amplification.
