Academic Publications

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

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.”
