“Long-Horizon Seasoned Equity Performance in the Pacific Rim Financial Markets”

Previous studies of firms that issue seasoned equity in the US and Japan have found that these firms significantly underperform over the long-run subsequent to the issue. I offer further evidence of this by examining Japanese seasoned offerings (SEOs) from 1975 to 1992. I find similar results for firms issuing seasoned equity in Hong Kong. However, I also find that Korean SEOs generate insignificant abnormal returns over a 36-month period following the issue. These results suggest that the asymmetric information argument offered for the US and Japanese markets do not always hold, especially in markets where the regulatory and market structures vary greatly. Cross-sectional results suggest that younger firms tend to perform worse than older firms.

“Machine Learning and Survey-based Predictors of InfoSec Non-Compliance”

Survey items developed in behavioral Information Security (InfoSec) research should be practically useful in identifying individuals who are likely to create risk by failing to comply with InfoSec guidance. The literature shows that attitudes, beliefs, and perceptions drive compliance behavior and has influenced the creation of a multitude of training programs focused on improving ones’ InfoSec behaviors. While automated controls and directly observable technical indicators are generally preferred by InfoSec practitioners, difficult-to-monitor user actions can still compromise the effectiveness of automatic controls. For example, despite prohibition, doubtful or skeptical employees often increase organizational risk by using the same password to authenticate corporate and external services. Analysis of network traffic or device configurations is unlikely to provide evidence of these vulnerabilities but responses to well-designed surveys might. Guided by the relatively new IPAM model, this study administered 96 survey items from the Behavioral InfoSec literature, across three separate points in time, to 217 respondents. Using systematic feature selection techniques, manageable subsets of 29, 20, and 15 items were identified and tested as predictors of non-compliance with security policy. The feature selection process validates IPAM's innovation in using nuanced self-efficacy and planning items across multiple time frames. Prediction models were trained using several ML algorithms. Practically useful levels of prediction accuracy were achieved with, for example, ensemble tree models identifying 69% of the riskiest individuals within the top 25% of the sample. The findings indicate the usefulness of psychometric items from the behavioral InfoSec in guiding training programs and other cybersecurity control activities and demonstrate that they are promising as additional inputs to AI models that monitor networks for security events.
