On March 8,2024, from 10:00 AM to 11:00 AM, Peking University Institute for Global Health and Development successfully hosted the second session of the Spring 2024 Reading Club. The keynote speaker for this event was Phd candidate Ran Li from Peking University Institute for Global Health and Development.

The article presented in this event is “ Estimates of the Economic Return to Schooling from a New Sample of Twins ”. This paper took some unusual steps to measure a worker's schooling level accurately. This paper collected a new Data to study the effect on regression of measurement error. The results indicate that the economic returns to schooling may have been underestimated in the past. This paper finds no evidence that unobserved ability is positively related to the schooling level completed; instead, this paper finds some weak evidence that unobserved ability may be negatively related to schooling level.
