SUMMARYThis paper examines the association between audit firm tenure and audit production efficiency. The analyses are based on proprietary audit production data provided by a large international accounting firm. The results document evidence of learning over time. Specifically, repeatedly servicing a client increases production efficiency by reducing the total audit hours expended in an audit engagement. Learning rates vary across different ranks of labor and learning is more pronounced among higher personnel ranks, with lower ranks experiencing little learning. Further, learning rates are not constant over time; there is little incremental learning beyond the initial productivity gains consistent with the concept of the learning curve. Finally, the results show some evidence of productivity losses as audit hours increase for very long tenures consistent with the notion of organizational forgetting.JEL Classifications: M41; M42
