This study investigates how the timing of the consideration of Big Data visualizations affects an auditor's evaluation of evidence and professional judgments. In addition, we examine whether the use of an intuitive processing mode, as compared to a deliberative processing mode, influences an auditor's use and evaluation of Big Data visualizations. We conduct an experiment with 127 senior auditors from two Big 4 firms and find that auditors have difficulty recognizing patterns in Big Data visualizations when viewed before more traditional audit evidence. Our findings also indicate that auditors who view Big Data visualizations containing patterns that are contrary to management assertions after they view traditional audit evidence have greater concerns about potential misstatements and increase budgeted hours more. Overall, our results suggest that Big Data visualizations used as evidential matter have fewer benefits when they are viewed before auditors examine more traditional audit evidence.
Our paper examines three related questions: Will directors who have friendship ties with the CEO manage earnings to benefit the CEO in the short term while potentially sacrificing the welfare of the company in the long term? Will public disclosure of friendship ties mitigate or exacerbate such behavior, and will disclosure of friendship ties influence investors' perceptions of director decisions? We conduct an experiment involving 56 active and experienced corporate directors from U.S. firms and a second experiment with M.B.A. students. We find that friendship ties caused directors to be more willing to approve reductions to research and development (R&D) expenses that cause earnings to rise enough to meet the CEO's minimum bonus target more often than when the directors and CEO were not friends. However, disclosing friendship ties resulted in even greater reductions in R&D expenses and higher CEO bonuses than not disclosing friendship ties. In a second experiment, we find that shareholders were more likely to agree with directors' decisions to approve cuts to R&D when friendship ties were disclosed. These findings have potentially important implications for corporate governance because they suggest that friendship ties between the CEO and board members can impair the directors' independence and objectivity, and that disclosure of the relationships can worsen this effect.
This research examines whether investors adjust their assessments of investment risk in response to material control weakness disclosures, the pervasiveness of material control weaknesses, and the detail of explanation provided regarding the pervasiveness of material control weaknesses. Findings from a laboratory experiment with 97 nonprofessional investors, a second experiment with 53 nonprofessional investors, and surveys of 47 investors and 28 Fortune 500 directors confirm prior archival findings that investors adjust their investment risk assessments in response to material weakness disclosures. More importantly, we find evidence of an interactive effect of material control weakness pervasiveness and disclosure detail that is counter to the expected benefits of expanded disclosure desired by corporate directors. When material weakness disclosures include specific and detailed discussion of the pervasiveness of control weaknesses, investors increase assessments of investment risk for less pervasive weaknesses and decrease assessments of risk for more pervasive weaknesses. Results indicate that these findings are driven by different levels of investor trust in management.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
