In this study, I investigate the effect of auditor-provided tax services (ATS) on firms’ levels of book-tax differences and investors’ mispricing of book-tax differences. The joint provision of audit and tax services has been a controversial issue among regulators and academic researchers. Evidence on whether ATS improve or impair the overall accounting quality is inconclusive as a result of the specific testing circumstances involved in different studies. Book-tax differences capture managers’ earnings management and/or tax avoidance intended to maximize reported financial income and to minimize tax expense. Therefore, my first research question investigates whether ATS improve or impair audit quality by examining the relation between ATS and firms’ levels of book-tax differences. My results show that ATS are negatively related to book-tax differences, suggesting that ATS improve the overall audit quality and reduce aggressive financial and/or tax reporting. My second research question examines whether the improved earnings quality for firms acquiring ATS leads to reduced mispricing of book-tax differences among investors. Recent studies document that despite the rich information about firms’ future earnings contained in book-tax differences, investors process such information inefficiently, leading to systematic pricing errors among firms with large book-tax differences. My empirical evidence indicates that ATS mitigate …

The purpose of this dissertation is to investigate the effect of U.S. firms’ geographic location, whether urban or rural, on their corporate disclosure and governance practices. An “urban” firm is one that is headquartered in a large metropolitan area; whereas, a “rural” firm is one that is headquartered some distance from any metropolitan area. Specifically, the study examines whether there are different stock market reactions to urban and rural firms around key event dates relative to the enactment of the Sarbanes-Oxley Act (SOX) on July 30, 2002. Also, the readability and linguistic style in the Management Discussion and Analysis (MD&A) section of public company’s annual reports (Form 10-K) to the Securities and Exchange Commission (SEC) are investigated to determine whether urban and rural firms communicate information differently to investors.

Client inquiry is a fundamental procedure for gathering audit evidence. Since inquiries are not audio- or video-recorded in practice, auditor memory is vital to the accuracy of evidence gathered in this manner. Due to the potential for error during memory encoding and retrieval, the effect of memory on judgment, and the cognitive complexity of conducting a face-to-face inquiry, examining factors affecting auditor memory of client inquiries is important. In this dissertation, I examine two factors likely to affect auditor memory of a client inquiry. First, encoding style is a low-level cognitive function representing how much stimuli an individual perceives before applying prior knowledge (schemata) to assist with encoding to long-term memory, affecting information noticed and remembered. Differences in auditors’ encoding style may explain variance in memory accuracy of evidence gathered from a client inquiry. Second, audit professionals often make hand-written or typed notes during client inquiries, and subsequently review the notes, which may affect memory. To address these issues, I first gather interview evidence from six professional auditors to determine how practicing auditors plan, prepare for, conduct, and document evidence from client inquiries. I then develop and execute a video-based experiment with 33 senior auditor participants, 23 masters-level accounting students, …

Many external parties such as investors, creditors, and regulatory agencies, use a company’s financial statements in their decision-making. In doing so, they rely on audit opinions on whether financial statements are fairly stated. However, evidence suggests that there are factors in the audit environment that influence auditor judgments. For example, nondiagnostic client information dilutes auditor judgments when compared to judgments based on diagnostic information alone, especially for less experienced auditors (Hackenbrack 1992; Hoffman and Patton 1997; Glover 1994; Shelton 1999). High time pressure conditions mitigate this effect by refocusing auditor attention toward relevant client information, therefore reducing the impact of nondiagnostic information (Glover 1994, 1997). This research study examines other common audit environment factors to determine if they too influence audit judgment results. An online questionnaire of 149 auditors, CPAs and other accounting professionals indicate that the inclusion of nondiagnostic client information results in a significant change in auditor judgments. The direction of this change follows a theorized pattern; risk assessments that were initially high are reduced, while those that were initially low are increased. Significance was not consistently found for a workload and PCAOB effect on auditor judgment. However, a comparison of the absolute value of dilution effect means …
