Short Bio


I am a macroeconomist and Professor of Economics at Seoul National University. I earned a Ph.D. in economics from the University of Rochester and have taught at the University of Pennsylvania (1997-2003), University of Rochester (2007-2018), and Yonsei University (2007-2018). Additionally, I have worked as a senior economist (2003-2004) and long-term consultant (2013-2023) at the Federal Reserve Bank of Richmond.

My research focuses on macroeconomics, particularly the development of heterogeneous-agents general-equilibrium models to investigate issues such as business cycles, labor supply, optimal taxation, and portfolio choices.

Currently, I am a member of the Monetary Policy Board of the Bank of Korea (on leave from SNU). I also serve as a co-editor of the Journal of Macroeconomics and as an advisory board member of the Carnegie-Rochester-NYU Conference Series on Public Policy. In 2023, I was elected as a fellow of the Econometric Society.
