行政数据与调查数据是否讲述了相同的影响故事？

中文摘要

职业培训评估面临一项选择：是使用调查数据、行政数据，还是同时使用二者来估计影响。我们利用卫生专业机会资助计划（HPOG 1.0）影响研究的数据，考察就业与收入的水平以及获得职业培训机会所产生的影响是否因数据来源而异——这些来源包括调查数据、全国新雇员名录数据和州失业保险数据。HPOG 1.0 对就业的影响在不同数据来源之间并无差异，但收入影响因数据来源而不同。行政数据分析发现了正向的收入影响，而调查数据分析未检测到任何收入影响。这些发现不同于相关研究——相关研究往往报告，用调查数据估计的收入影响大于用行政数据估计的收入影响。

Abstract

Abstract Job training evaluations face a choice: whether to use survey data, administrative data, or both to estimate impacts. Using data from the Health Profession Opportunity Grants (HPOG 1.0) Impact Study, we investigate whether employment and earnings levels and impacts of gaining access to occupational training differ by source: survey data, National Directory of New Hires data, and state Unemployment Insurance data. Impacts of HPOG 1.0 on employment do not differ, but earnings impacts differ between the data sources. Administrative data analysis finds positive earnings impacts, whereas survey data analysis detects none. These findings differ from related research, which tends to report that earnings impacts estimated from survey data are larger than those estimated from administrative data.
