LinkedIn(to) Job Opportunities: Experimental Evidence from Job Readiness Training
通过随机实验评估求职准备培训对使用领英平台的影响，发现培训使项目结束时的就业率提高10个百分点，且效果持续至少12个月，机制是求职者通过平台获取雇主信息并可能获得推荐。
Online professional networking platforms are widely used and may help workers to search for and obtain jobs. We run the first randomized evaluation of training work seekers to join and use one of the largest platforms, LinkedIn. Training increases the end-of-program employment rate by 10 percent (7 percentage points), and this effect persists for at least 12 months. The available employment, platform use, and job search data suggest that employment effects are explained by work seekers using the platform to acquire information about prospective employers and perhaps by work seekers accessing referrals and conveying information to prospective employers on the platform.
