معرفی
Yiguo Sun is a Professor of Economics and University Research Leadership Chair at the University of Guelph, Department of Economics and Finance. She specializes in econometrics, focusing on semi-/nonparametric methods for panel data, non-stationary time series, and spatial regression models. Her research addresses issues such as investment dynamics, social interactions, and threshold effects. She holds a B.Sc. and M.Sc. from Hebei Normal University, an M.A. from the University of Guelph, and a Ph.D. from the University of Toronto. Awards include the CBE Senior Research Fellow (2018-2021) and University Research Leadership Chair (2022-2025).
Education:
- B.Sc. in Mathematics, Hebei Normal University (1993)
- M.Sc. in Mathematics, Hebei Normal University (1996)
- M.A. in Economics, University of Guelph (1997)
- Ph.D. in Economics, University of Toronto (2002)
Research Interests:
Dr. Sun’s work centers on advancing econometric methodologies, particularly in nonparametric and semiparametric frameworks. Key areas include:
- Threshold regression models and their applications in inflation dynamics and social interactions
- Spatial econometrics and panel data analysis
- Nonlinear estimation techniques addressing endogeneity and measurement error
- Economic growth and natural resource nexus
Recent Contributions:
Her 2024 paper on investment-uncertainty relationships introduced a novel estimator addressing endogeneity and measurement bias. The 2023 Social Threshold Regression advanced peer effect analysis through a spatial Durbin framework. Recent articles explore spatial spillovers in trade policies and Canadian inflation dynamics using threshold models.
Awards:
- University Research Leadership Chair (2022-2025)
- CBE Senior Research Fellow in Spatial Econometrics (2018-2021)
- SSHRC Insight Grant (2022-2025)
Grants & Advising:
She leads SSHRC-funded projects on social networks and measurement errors in finance. Supervised students include Delong Li (investment dynamics), Chaoyi Chen (threshold estimation), and Hui Xiao (model averaging). Research teams focus on econometric theory and applied policy analysis.
Labs/Teams:
Active in the University of Guelph’s CBE research community, collaborating with Thanasis Stengos, Emir Malikov, and international scholars on spatial econometrics and nonlinear methods.
