I am a macroeconomist and Professor of Economics at Seoul National University. I received my Ph.D. in Economics from the University of Rochester and have previously held academic positions at the University of Pennsylvania (1997–2003), Seoul National University (2004-2007), the University of Rochester (2007–2018), and Yonsei University (2007–2018). I also worked as a senior economist at the Federal Reserve Bank of Richmond (2003–2004) and continued to serve as a long-term consultant (2013 to 2023).
My research centers on macroeconomics, with a particular focus on developing heterogeneous-agent general-equilibrium models to analyze business cycles, labor supply, optimal taxation, and portfolio choices.
I currently serve as a co-editor of the Journal of Macroeconomics and am on the Advisory Board of the Carnegie-Rochester-NYU Conference Series on Public Policy (previously served an associate editor of the Journal of Monetary Economics and an editorial board member of the American Economic Journal: Macroeconomics).
In 2023, I was elected as a Fellow of the Econometric Society and am currently serving as a member of the Monetary Policy Board at the Bank of Korea.
