Accounting & Management Control
Assistant Professor, Accounting & Management Control
Thomas Gilliam thrives on producing research with concrete implications for business and society. This focus stems from a passion for business that he developed while an executive in Silicon Valley. Professor Gilliam had significant financial and operational responsibilities with large multinational technology companies including Silicon Graphics, Inc., LG Corp., Xerox Corp., and Telesensory Systems, Inc. At Silicon Graphics, Professor Gilliam was responsible for the financial affairs of a $1.5 billion computer business and for the operational activities of a $100 million data storage business which he co-founded.
As an executive, Professor Gilliam saw first-hand that many financial decisions were made using heuristics or rules of thumb and that many other financial decisions were dictated by regulators. From these observations Professor Gilliam developed a deep seated curiosity about the effects of such decision making which has in turn led to many of his research questions. For example, after seeing companies expend large amounts of time and money to comply with the Sarbanes-Oxley Act (SOX), Professor Gilliam wanted to know if SOX had actually achieved one of its stated intents – curtailment of financial reporting manipulation. To gain insight, Professor Gilliam examined earnings management to avoid reporting small losses. In a forthcoming article Professor Gilliam reports that the once prevalent practice of loss avoidance disappears immediately after the enactment of SOX and does not return. These findings provide important insights into the on-going debate about the efficacy of SOX.
Professor Gilliam also brings his enthusiasm for business to the classroom where he teaches management accounting and control management.
