FINANCIAL TIMES CONTRIBUTIONS

US equity markets have never been safer - Despite the title, this Financial Times Alphaville story includes measures for the total value destruction by key underwriters and auditors. Here’s a pdf version.

Trump Media’s auditor is really bad at spelling his own name (ft.com) - Auditor “Ben Borgers” had been on my radar for about a year before I sent the data to the FT. Kudos to the SEC and PCAOB for shutting him down. Here’s a pdf version—hilarious read!

ACADEMIC PUBLICATIONS

Walker, S. (2021). Machine Learning and Corporate Fraud Detection. University of California, Berkeley.

  • My dissertation dives deep into corporate fraud models, and explains why finding the needle in the haystack is likely to stay there.

PEPFAR Spending Types and Reduction in HIV Infection Rates | medRxiv (Working Paper, 2022)

  • In this paper, I measure and document marginal effects of various spending types of the PEPFAR program (e.g., treatment, prevention, etc.) on new HIV infections.

I have four publications with Econ Journal Watch. In this series:

  • I identify problems with using Benford’s Law in corporate fraud detection

  • I call for an investigation into academic misconduct relating to a “fraud detection paper” published in a top academic journal following identification of problematic coding “errors.”
