Introduction
My research reflects a longstanding interest in the areas of market-based accounting, textual analysis and natural language processing. My main research interests lie in corporate disclosures and information intermediaries. Some of my recent work examines the role of the financial media in the information transmission process relative to corporate announcements, and the extent to which the financial press serves as an important information intermediary in the capital markets.

Using a sample of...
This study finds that the financial press serves an important monitoring role by interpreting the tone of corporate announcements, moderating its impact to market participants in the process. Using textual analysis, we report that the press attenuates both the positive and negative tone of firm-initiated disclosures. However, the effect is asymmetr...
We examine the role of voluntary corporate press releases about firms’ financial performance as a stimulus for financial media coverage. We find that there is a spike of media articles on the same day and one trading day following firms’ press releases.
