Variance Reporting, Belief Revision, and Profitability

Attribution bias can be costly to firms because it hinders decision makers’ ability to infer the real cause of prior events and take corrective action to improve future performance. This study extends prior research by examining whether and how the presence of variance reporting from accounting systems affects firm profitability through a labor cost management decision that is highly susceptible to attribution bias. Our results support the prediction that the presence of variance reporting (process feedback) increases the likelihood of belief revision and corrective action related to the systematic error, and thus increases overall profitability for the firm. The findings of our study propose a solution to attribution and learning problems observed when decision makers are responsible for both cost management and bids as documented in prior literature.
