Human Versus Machine: A Comparison of Robo-Analyst and Traditional Research Analyst Investment Recommendations

The Accounting Review 2022 97(5), 221-244
ABSTRACT We provide the first comprehensive analysis of the properties of investment recommendations generated by “Robo-Analysts,” which are human analyst-assisted computer programs conducting automated research analysis. Our results indicate that Robo-Analyst recommendations differ from those produced by traditional “human” research analysts across several important dimensions. First, Robo-Analysts produce a more balanced distribution of buy, hold, and sell recommendations than do human analysts and are less likely to recommend “glamour” stocks and firms with prospective investment banking business. Second, automation allows Robo-Analysts to revise their recommendations more frequently than human analysts and incorporate information from complex periodic filings. Third, while Robo-Analysts' recommendations exhibit weak short-window return reactions, they have long-term investment value. Specifically, portfolios formed based on the buy recommendations of Robo-Analysts significantly outperform those of human analysts. Overall, our results suggest that automation in the sell-side research industry can benefit investors. JEL Classifications: G14; G24.

Does the Scope of the Sell‐Side Analyst Industry Matter? An Examination of Bias, Accuracy, and Information Content of Analyst Reports

Journal of Finance 2017 72(3), 1285-1334
ABSTRACT We examine changes in the scope of the sell‐side analyst industry and whether these changes impact information dissemination and the quality of analysts’ reports. Our findings suggest that changes in the number of analysts covering an industry impact analyst competition and have significant spillover effects on other analysts’ forecast accuracy, bias, report informativeness, and effort. These spillover industry effects are incremental to the effects of firm level changes in analyst coverage. Overall, a more significant sell‐side analyst industry presence has positive externalities that can result in better functioning capital markets.

Do Jobseekers Value Diversity Information? Evidence from a Field Experiment and Human Capital Disclosures

Journal of Accounting Research 2023 61(3), 695-735 open access
ABSTRACT We examine how information about the diversity of a potential employer's workforce affects individuals’ job‐seeking behavior. We embed a field experiment in job recommendation emails from a leading career advice agency in the United States. The experimental treatment involves highlighting a diversity metric to jobseekers. Our results indicate that disclosing diversity scores in job postings leads jobseekers to click on firms with higher diversity scores, with such effects varying across jobseeker demographics. A follow‐up survey provides evidence on potential explanations for why jobseekers value diversity information. We then examine how jobseekers’ preferences for diversity relate to disclosure choices under the U.S. SEC Human Capital Disclosure requirement. We find that firms in industries characterized by higher jobseeker responsiveness to diversity information tend to voluntarily disclose diversity metrics in their 10‐Ks under these new disclosure requirements.

Common Media Holding Companies and the Uniqueness of Business Press Content

The Accounting Review 2025 100(1), 381-405
ABSTRACT We examine how common media holding companies impact the uniqueness of business press content. Consistent with common media holding companies reducing the diversity of perspectives among journalists, we find that media outlets are more likely to cover the same earnings announcement and utilize more similar tone and content when they belong to a common holding company. We provide evidence that these effects are enhanced by outlet reach and economic incentives to share content. Finally, we provide evidence consistent with coverage by common media holding companies impeding price formation. Overall, our findings suggest that content within common media holding companies is less diverse and that this may have negative implications for markets.

Do Internal Control Weaknesses Affect Firms’ Demand for Accounting Skills? Evidence from U.S. Job Postings

The Accounting Review 2023 98(3), 203-228
ABSTRACT In this study, we examine whether firms respond to internal control weaknesses (ICWs) by requiring accounting-specific skills when hiring rank-and-file employees. Using unique data containing an extensive collection of job postings, we document significant increases in firms’ job postings that list accounting skills after the disclosure of an ICW. This effect is more pronounced for firms with better financial resources and when ICWs are more severe or personnel-related. In addition, our results extend to employees that are not specifically designated as accountants, suggesting a broader role for rank-and-file employees in influencing internal control quality. Finally, we find that increases in job postings with accounting skill requirements are associated with improvements in internal controls and a higher likelihood of ICW remediation. Overall, our findings shed new light on how firms respond to ineffective internal controls by increasing their emphasis on accounting skills in their workforce.
