Professor Cedergren’s research focuses on disclosure activity and its relationship with securities litigation and regulations. In a recent paper in the Journal of Accounting and Economics, he investigates how managers’ trading activity affects their likelihood to warn of impending negative earnings surprises, and how potential class action plaintiffs use observed trading in deciding whether to initiate litigation when such negative surprises manifest. Professor Cedergren’s research interests also include initial public offerings, accounting issues in high-tech firms, and the capital market effects and information content of accounting measures.
Prior to his academic career, Professor Cedergren spent six years in the Assurance practice of PricewaterhouseCoopers LLP in San Jose, California, where his responsibilities included financial statement audits and Sarbanes-Oxley compliance for semiconductor clients in Silicon Valley. While at PwC, Professor Cedergren also worked on several stock option backdating investigations and related financial restatements, including those of Mercury Interactive, Marvell Technology Group, and Trident Microsystems.
Professor Cedergren obtained his PhD from the New York University Leonard N. Stern School of Business, his BBA/MAcc from the University of Wisconsin-Madison, and is a CFA charterholder and Certified Public Accountant (licensed in California).
