Summary

Yoosoon Chang is an expert in the application of time series, panel data, and machine learning models to facilitate the implementation of frontier theories and methodologies. She visited the Stone Center on April 7 and April 22, 2023 to advance a long-term research project joint with Faculty Director Steven Durlauf, Seunghee Lee, and Joon Park which aimed to determine what exposures and experiences between childhood and adolescence are predictive of adult outcomes. Their work emphasized how marginal changes in parents’ income at each age of their offspring’s lives affect the permanent income of those offspring later in life and finds that parents’ incomes in middle childhood and adolescence have larger marginal effects than incomes in early childhood. This paper also offered an improved methodology that provides optimal extraction paths, reduced bias within, and improved stability of models related to mobility.
