Attrition from Administrative Data: Problems and Solutions with an Application to Postsecondary Education
研究了行政数据中个体流失导致的偏差，以高等教育对劳动力市场的影响为例，发现跨州迁移导致的流失对高收入者、名校毕业生和特定专业影响显著，并评估了量化偏差的方法。
Abstract This paper documents the bias introduced by attrition of individuals from administrative data with an application to the labor market consequences of postsecondary education. Attrition due to crossstate migration is non-trivial, particularly for high-earners, graduates from selective universities, and certain majors. Consequently, the premium associated with graduating from a most selective university is 23% higher than in-state earnings suggests, though this magnitude differs across context. The impact of obtaining a 2-year CTE credential is also understated, as are earnings differences across majors. Differences in missingness are systematically related to bias in measurement; we evaluate approaches to quantifying that bias.
