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.
