Prof Lai Wei
  • Lai Wei is an Assistant Professor in Sociology at the University of Hong Kong. Before joining HKU, he completed a BA in sociology from Tsinghua University in 2018 and a PhD in sociology from Princeton University in 2024. He studies social stratification and quantitative methodology, focusing on intergenerational mobility and causal inference. His past works try to adapt, develop, and apply causal inference methods to understand the causes, mechanisms, and consequences of social mobility. Some past studies under this general theme include: (1) What is the impact of intergenerational (im)mobility on average fertility and income inequality in the United States? (2) What is the impact of rising parental levels of education on intergenerational income inequality in the United States? (3) How has the change in labor market demands affected the channels of intergenerational economic transmission in the United States?

Underlying this agenda is a new methodological program called “causal intervention”. The second focuses on how the transformation of the educational system and the labor market environment affected intergenerational mobility in the United States.
