Professor Sung Wook Joh of Seoul National University (SNU) Business School graduated from SNU (BA, Economics) and Harvard University (PhD, Economics). Dr. Joh advised and evaluated government policies on chaebols and competition policy while working for the Korea Development Institute (KDI) during 1997-2003. After joining SNU, she served as a commissioner for Korea’s Securities and Futures Commission (similar to SEC) and currently is a member of Korea’s Regulatory Reform Committee. She served as president of the Financial Information Society of Korea and vice president of the Korea Monetary and Finance Association (KMFA). She is currently an auditor for KMFA and director for Korea Academic Society of Industrial Organization.

Dr. Joh is an expert on competition policy, chaebol policy and corporate governance. She shows how firms and people behave in challenging environments with increased competition, financial distress and exit threats. For example, her study showed that as corporate managers’ compensation affects their efforts, firms can use manager incentives to encourage them to collude with rival firms to reduce product market competition (Review of Economics and Statistics). Dr. Joh also showed that people in organizations facing severe competition perform worse, suggesting that restructuring should be quick (BE Journal of Economic Analysis and Policy). Also, Dr. Joh analyzes micro-dynamics of SMEs, and their public offerings (IPOs).

In addition, she showed that poor corporate governance of debt ridden firms and chaebols reduced firm profits and caused cascading bankruptcies, which drove the 1997 economic crisis in Korea --this study is in the Hall of Fame at the Journal of Financial Economics. Dr. Joh has also analyzed corporate governance issues including business groups, management incentive system, board of directors, and political assets.
