Feeling Observed? A Field Experiment on the Effects of Intense Survey Participation on Job Seekers’ Labor Market Outcomes
通过随机排除愿意参加高强度调查的求职者，发现调查参与对一年后的劳动力市场结果无显著影响，并指出基于可观测变量的方法会产生误导。
The authors causally identify the effects of intense survey participation on key labor market outcomes by randomly excluding individuals willing to sign up for a high-intensity survey with a focus on job search and well-being. Using administrative data, they find that, on average, survey participation had no effect on labor market outcomes during the year after signing up. They also demonstrate that an alternative selection-on-observables approach would yield misleading results. These findings underscore the value of experiments in examining effects of survey participation.
