The paper explores the consequences of SEC detection of illegal insider trading on subsequent insider trading activities. We hypothesize that individuals with private information update their subjective probabilities of getting caught and are less likely to exploit material, non-public...

This paper contributes to the debate on the consequences of increased disclosure regulation by investigating the effects of expedited reporting requirements of Form 4 filings, mandated by the Sarbanes-Oxley Act (SOX), on the market response to earnings announcements. We first confirm that SOX...
