Department of Economics

Dr. Chang is a Professor of Economics at Indiana University with a Ph.D. in Economics from Yale University. She is an Advisor of the Stone Center for Research in Wealth Inequality and Mobility (SCRWIM) in the Harris School of Public Policy at University of Chicago, an Executive Committee member of the Institute of Korean Studies in the School of Global and International Studies at Indiana University, an Adjunct Researcher at the BI Norwegian Business School, and a Visiting Distinguished Fellow of Samsung Global Research (SGR). She previously served as the Head of the Department for the Department of Economics at Texas A&M University and the Director of Graduate Studies at Indiana University. Her other current professional responsibilities include her roles as the Coordinator of Midwest Econometrics Group (MEG), Organizer of Symposium of Econometric Theory and Applications (SETA), Co-organizer of the Workshop on Energy Economics, an Executive Committee member of Studies in Nonlinear Dynamics & Econometrics (SNDE), President-elect of Korea America Economic Association (KAEA), and a member of Editorial Board of Journal of Economic Literature, Associate Editor of Journal of Applied Econometrics, Journal of Econometrics, Journal of Time Series Econometrics and SNDE. She was a Visiting Professor at the University of Chicago, Keio University, BI Norwegian Business School, Fudan University, University of Tokyo and Yale University. She is the recipient of 2022 Maekyung-KAEA Economist Award, and an elected fellow of Journal of Econometrics and International Association for Applied Econometrics.

Dr. Chang’s current research interests include the application of various time series, panel data, and machine learning models to facilitate the implementation of frontier theories and methodologies for practically relevant inference in a broad range of macroeconomic 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, inflation forecast distribution, yield curve, and labor force participation profile. These studies help better address some pressing economic issues, including income-educational-occupational mobilities, policy effects on income inequality, climate change, effects of expansionary monetary and fiscal policies on inflation, 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 takes mentoring junior women economists seriously and has been playing a leadership role, either as an organizer or as a key participating mentor, in numerous mentoring events, including the MEG mentoring workshops, CeMENT workshops organized by the 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 the Chair of the Korean Women Economists Network (KWEN) and is a member of the International Advisory Board of the Association of the Advancement of African Women Economists (AAAWE).
