Sang Wu joined Columbia University in 2022. Her research focuses on the role of information in the interaction between agents, along with its implications on the real efficiency and the price efficiency of financial markets. She uses analytical models as a tool to explain empirical anomalies in accounting practices and institutions that contradict conventional wisdom. Her current research centers around two themes: (i) how various characteristics of accounting information as mandated by accounting standards influence investors’ assessment of a firm’s future profitability and their trading behaviors in capital markets, and (ii) what are the incentives of investors or firms to disclose their private information in a coordination or competitive setting.
Before joining Columbia, Professor Wu earned her Ph.D. in Accounting from Carnegie Mellon University Tepper School of Business where she received the Alexander Henderson Award for Excellence in Economic Theory and the William W. Cooper Doctoral Dissertation Award. She also holds a bachelor’s degree in Business Administration (Accounting and Finance) from the University of Hong Kong.
