Decision Outcomes Under Activity-Based Costing: Presentation and Decision Commitment Interactions

Activity-based costing (ABC) is presented in accounting textbooks as a costing system that can be used to make valuable managerial decisions. Little experimental or empirical evidence, however, has demonstrated the benefits of ABC under controlled conditions. Similarly, although case studies and business surveys often comment on business environments that appear to favor ABC methods, experimental studies of actual behavioral issues affecting ABCs usage are limited. This study used an interactive computer simulation, under controlled, laboratory conditions, to test the decision usefulness of ABC information. The effects of presentation format (theory of cognitive fit and decision framing), decision commitment (cognitive dissonance), and their interactions were also examined. ABC information yielded better profitability decisions, requiring no additional decision time. Graphic presentations required less decision time, however, presentation formats did not significantly affect decision quality (simulation profits). Decision commitment beneficially affected profitability decisions, requiring no additional time. Decision commitment was especially influential (helpful) in non-ABC decision environments.
