📅 November 2-6, 2026
🎓 PhD-level

Course objective and motivation

The overarching objective of this course is to provide students with insights into the economic foundations and aspects of financial statement auditing and assurance. Auditing and assurance services are economic goods that are demanded, produced, and supplied in the audit market at equilibrium prices. In this course, we will focus on a number of economic topics related to auditing and assurance. These include a discussion of the (economic) nature of auditing, the production and pricing of auditing services, audit market structure and auditor competition, economic incentives of audit partners, and the economics of audit regulation. We cover these topics through the reading and discussion of academic papers related to these topics.
