- Ph.D., Yale University, 1995
Dr. Chang is a Professor of Economics at Indiana University with a Ph.D. in Economics from Yale University. She is an Executive Committee member of the Institute of Korean Studies in the School of Global and International Studies at Indiana University, and a Visiting Scholar at BI Norwegian Business School. Her other current professional responsibilities include her roles as the Organizer of Symposium of Econometric Theory and Applications (SETA), Coordinator of Midwest Econometrics Group (MEG), Co-organizer of the Workshop on Energy Economics, an Executive Committee member of Studies in Nonlinear Dynamics & Econometrics (SNDE), and an Associate Editor of Journal of Time Series Econometrics and SNDE. She was a Visiting Professor at the University of Chicago, Keio, BI Norwegian Business School, Fudan, University of Tokyo and Yale.
Dr. Chang's current research interests include the application of various time series, panel data and machine learning models to facilitate implementation of frontier theories and methodologies for practically relevant inference in a broad range of economic and financial models. Her recent research focuses on functional time series, endogenous regime switching models, high frequency factor models and their applications in intergenerational mobility, policy effects on functional outcomes such as income distribution, temperature anomaly distribution, yield curve and employment profile. These studies help better address some pressing economic issues, including income-educational-occupational mobilities, climate change, borrowing costs of government and job polarization. Her recent research also investigates monetary and fiscal policy interactions, income dynamics, expectation effects of switching financial market conditions, and empirical asset pricing models with macro factors. She has applied her new methodologies to analyze energy demand and longevity risk. Dr. Chang’s research has been published in Review of Economic Studies, Quantitative Economics, Journal of Economic Dynamics and Control, Journal of Econometrics, and Energy Economics, among others. Her work has been funded by the National Science Foundation, Bank of Korea, KEPCO, Korea Power Exchange, and the Norwegian Research Council.
Dr. Chang has been involved in mentoring junior women economists in various contexts, including the MEG mentoring workshops, CeMENT workshops organized by Committee on Status of Women in Economics Profession (CSWEP) of AEA, Finance and Economics Women (FEW), and Women Economists Networks of China, Japan and Korea. She is also serving as Chair of Korean Women Economists Network (KWEN) and is a member of the International Advisory Board of Association of the Advancement of African Women Economists (AAAWE).
