Research Notes

“Here I share short notes, empirical workflows, econometric insights, and informal writing on economic theory, data practices, and real-world social dynamics.”

🛠️ Empirical Workflows & Code Logic

1. Code and Data for Social Scientists: A Practitioner’s Guide to Programming Logic

  • Original Title: 一份值得推荐给所有学术人的编程底层逻辑指南
  • Link: Read Original Article (Chinese)
  • Themes: Empirical Workflows, Code Abstraction, Version Control, Automation, Project Management
  • Core Intuition: A practitioner’s guide summarizing 12 core programming and data management principles for empirical research, adapting industrial software engineering practices into social science research workflows.

📊 Econometric Notes & Identification

2. Handling Fixed Effects in Predictions Under High-Dimensional Fixed Effects (HDFE) Models

  • Original Title: HDFE模型在对因变量进行预测时，如何处理固定效应？
  • Link: Read Original Article (Chinese)
  • Themes: High-Dimensional Fixed Effects, HDFE Prediction, reghdfe, fixest, Average Partial Effects
  • Core Intuition: A deep dive into the econometric logic of predictions in HDFE models. Grounded in Wooldridge’s Average Partial Effects (APE) framework, I unpack why Stata’s reghdfe and R’s fixest predict net of fixed effects to isolate covariate-driven average conditional means.

3. How Does Random Measurement Error Systematically Bias Econometric Estimation?

  • Original Title: 变量的随机测量误差如何影响估计结果？
  • Link: Read Original Article (Chinese)
  • Themes: Measurement Error, Classical vs. Non-Classical Errors, Attenuation Bias, OLS Bias
  • Core Intuition: An econometric breakdown of classical vs. non-classical measurement errors in dependent and independent variables, drawing insights from Wooldridge (2010) and Goldin & Rouse (2000, AER).

💡 Perspectives & Epistemology

4. Is Economics More Like Physics or Chemistry? Methodological Reflections on the Semi-Empirical Paradigm

  • Original Title: 经济学更像物理还是化学？
  • Link: Read Original Article (Chinese)
  • Themes: Epistemology, Physics Envy, Semi-Empirical Paradigm, Market Design
  • Core Intuition: A methodological reflection on “physics-envy” in mainstream economics. Drawing inspiration from chemical engineering (as advocated by Alvin Roth), I reflect on why economics thrives best as a semi-empirical discipline—anchoring itself on foundational micro-axioms while leveraging empirical flexibility to tackle real-world market complexities.

5. Why Do High-Human-Capital Women Get Trapped in Low-Quality Relationships? A Resource Misallocation Perspective

  • Original Title: 为什么高智女性更容易陷入劣质亲密关系？
  • Link: Read Original Article (Chinese)
  • Themes: Human Capital Misallocation, Social Norms, Gendered Incentives, Opportunity Cost
  • Core Intuition: A brief thought exercise applying microeconomic concepts to personal observations on relationship dynamics. I reflect on how problem-solving habits, opportunity costs, and gendered social expectations shape how individuals navigate personal choices and emotional investments.
