Auditor Automation Usage and Professional Skepticism
Job Market Paper
Abstract: Audit firms increasingly employ automated tools and techniques in auditing procedures. The premise of using automation is that it increases audit effectiveness and audit efficiency. For these effectiveness and efficiency gains to materialize, auditors need to use automation in an adequate manner. Regulators, however, have raised concerns that auditors may over- or under-rely on automation. I predict that auditors are subject to an automation bias and use cues from automated tools and techniques as a replacement for vigilant information seeking, thereby reducing professional skepticism when relying on automation. My findings are in line with my predictions. When auditors rely on work conducted by automated tools and techniques, they are less skeptical than when relying on the same work conducted by an audit team member. Based on psychology theory, I employ a counterarguing mindset intervention that alleviates the negative effects of automation on professionally skepticism. Finally, I also test whether a reduction in vigilance caused by automation usage spills over to subsequent tasks. I do not find evidence indicating a spillover effect. Implications for practice and theory are discussed.

Auditor Task Prioritization: The Effects of Time Pressure and Psychological Ownership
Co-authored with Bart Dierynck
Abstract: This paper reports three studies examining easy task prioritization among auditors. The first study is a survey of auditors providing evidence that auditors perceive easy task prioritization to be a threat to audit quality, yet auditors do expect other auditors to prioritize easy tasks. In our first experiment, we find that auditors indeed prioritize easy tasks. Easy task prioritization is also exacerbated under time pressure. We further find that psychological ownership is only able to alleviate easy task prioritization in low time pressure conditions, but not in high time pressure conditions. In our second experiment, we find that prioritizing the easy task leads to lower judgment performance, and by extension, audit quality. The performance detriment of easy task prioritization manifests itself in the difficult task, and in particular in finding errors for which more cognitive processing is needed. Combined, our studies document easy task prioritization in auditing, the audit quality implications, and the role of time pressure and psychological ownership.

Learning in the Auditing Profession: A Framework and Future Directions
Abstract: Drawing on literature in auditing and workplace learning, this paper develops the Auditor Learning Framework. Based on the general workplace learning framework by Jacobs and Park (2009), the Auditor Learning Framework distinguishes auditor learning processes along two dimensions: the location of learning (on-the-engagement or off-the-engagement) and the role of the others in the learning process (active or passive). We review the auditing literature, classifying papers that directly or indirectly improve our knowledge of auditor workplace learning into our framework to identify gaps in our understanding of the auditor learning processes. Our study provides a comprehensive view of auditor learning processes and provides suggestions for future research aimed at improving auditor workplace learning.
Public Tax Disclosures and Fair Share Perceptions
Abstract: To reveal whether firms pay their fair share of taxes, regulators increasingly mandate public tax disclosures. Such disclosures are often assumed to raise awareness and scrutiny of firms’ tax aggressiveness and should thus help stakeholders identify aggressive tax avoiders. We conducted two experiments to test this assumption. The first experiment indicate that stakeholders become worse at identifying aggressive tax avoiders when public disclosures focus on bottom-line tax numbers. The reason is that stakeholders use such disclosures as a heuristic for a firm’s tax aggressiveness and are reluctant to acquire complementary, more detailed tax information. The results of the second experiment demonstrate that policies to counteract the adverse effects of public tax disclosures (i.e., a disclaimer, more detailed public tax information, and country-by-country reporting) are helpful but none can achieve the actual policy goal of improved identification of aggressive tax avoiders.

Corporate Tax Planning and Industry Concentration
Abstract: Recent research has documented that industry concentration has increased significantly over the past 25 years, with potentially negative consequences for competition, productivity, and social welfare. Some have suggested that greater corporate tax planning by industry leaders, which can provide them with a cost advantage over their competitors, has contributed to this trend. As a result, policymakers are targeting such tax planning to reduce industry concentration. We provide large-sample empirical evidence on whether tax planning is associated with industry concentration. In contrast with conventional wisdom, we find that industry leaders generally do not exhibit greater tax planning relative to their closest competitors. Furthermore, industry leader tax planning advantages do not meaningfully explain the trend in industry concentration over our sample period. Finally, we document that industries with plausibly tax planning-induced concentration do not exhibit different aggregate productivity growth than other industries. In short, our findings cast doubt on the idea that corporate tax planning is responsible for increasing industry concentration or other anti-competition industry-level outcomes in recent years.

Survival of the Tax Fittest: Path Dependence in Corporate Tax Planning
Abstract: We investigate the potential of path dependence in explaining cross-sectional variation and persistence in efficient corporate tax planning. Variation in tax planning efficiency among firms is far from being fully understood. We propose that corporate tax planning strategies are path dependent. This implies that once a business strategy is adopted, this narrows the range of tax strategies available to the firm. Once a more efficient tax planning strategy emerges, path dependence hampers firms from adopting that option, potentially resulting in tax planning inefficiencies. We compare new entrants to a market with incumbent firms, and find that new entrants have an Entrant's Tax Edge. That is, new entrants are more efficient in tax planning compared to incumbent firms. Consistent with our predictions and path dependence theory, we find that the Entrant's Tax Edge is amplified when incumbent firms in the market are relatively inflexible. Finally, we explore whether new entrants use their tax edge as a competitive mechanism. We find new entrants only outperform incumbents in tax planning efficiency when competition is high, but not when competition is low.
