Systematic Misreporting and Effects of Income Maintenance Experiments on Work Effort: Evidence from the Seattle-Denver Experiment
利用雇主报告的数据，发现西雅图和丹佛收入维持实验中，实验组和对照组在自我报告工作努力上的差异导致先前估计的劳动供给减少效应被高估，实际影响比基于访谈数据的估计更温和。
Previous estimates of the effects of the Seattle and Denver income maintenance experiments on labor supply indicate that persons eligible for experimental payments reduced their work effort by appreciable amounts. However, these estimates have all been based on data that were self-reported during interviews by participants in the experiment. This paper investigates whether the estimates are biased by differences between treatment and control groups in reporting accuracy. Our results, which utilize employer-reported information on participants' work effort, suggest that the experiment's effects on several categories of Seattle and Denver participants were less adverse than estimates based on self-reported interview data imply.
