摘要 / Abstract
We use a structural applicationof the discrete choice model to investigate how the introduction of a jointaudit policy would affect audit market structure and consumer surplus. Weperform this policy evaluation by identifying demand fundamentals in a jointaudit regime and applying them to a single audit regime. We find that a jointaudit requirement has the potential to change the audit market structuresubstantially but that the effects are sensitive to the specific policy design.For example, small audit firms gain market share in a joint audit regime butonly if an equal sharing of the workload between the two joint auditors is notrequired.
Our counterfactual analysisreveals that the introduction of a joint audit regime would be associated witha substantial loss of consumer surplus. The loss results from restrictingclients from giving all of the audit work to their most preferred audit firm,but it is partly offset by gains in consumer surplus deriving from theopportunity to choose the best combination of auditor pairs.
