The Anatomy of U.S. Sick Leave Schemes: Evidence from Public School Teachers
研究了公立学校教师如何使用带薪病假，发现病假使用在流感季增加，平均而言教师不会为休闲而请假，但年轻无经验者除外，且病假余额越高使用越多，高余额教师更少带病工作。
Abstract We study how public school teachers use paid sick leave. Most US sick leave schemes operate as individualized credit accounts: Paid leave is earned, and unused leave accumulates. We construct a unique dataset of daily leave balances and behavior among 982 teachers for 2010–2018. Sick leave use increases during flu season, and evidence indicates that the average teacher does not use sick leave for leisure, though some subsets of teachers (e.g., the young and inexperienced) do. Usage increases with leave balance; the elasticity is around 0.4. Further, teachers with higher balances are less likely to work sick, particularly during flu season.
