Private companies are significant to the U.S. economy as well as audit firms. I hand-collect auditors' private client information and construct a national, city, and joint national/city specialist designation and document a 17.9 to 47.3 (12.9 to 25.8) percent decrease in a public client's likelihood to misstate their financial statements (net income earnings management) when an auditor is a private client industry specialist. I then construct and test a city specialist measure using both private and public client data and find that it is economically stronger and more robust than the public only measure commonly employed by audit researchers. This study provides evidence of the importance of private companies to an audit firm's industry expertise as well as to researchers' use of city specialist measure in audit studies.ETDIn CopyrightAuditor industry expertiseAudit officeMisstatementsAccrualsand Audit feesDissertation
