Who Is Coming to the Artefactual Field Experiment? Participation Bias among Chinese Rural Migrants

In this paper, we compare participants in an artefactual field experiment in urban China with the survey population of migrants from which they were recruited. The experimental participants were more educated, more likely to lend money to friends, and worked fewer hours than the general population.

本文将中国城市地区开展的人工田野实验（artefactual field experiment）的参与者，与招募该批参与者的移民调查目标人群进行对比。研究发现，相较于该移民调查总体人群，实验参与者受教育程度更高、更倾向于向朋友出借资金，且工作时长更短。
