Studies analysing the effect of the duration of sick leave on subsequent labour market outcomes do not consider the potential endogenous relationship between duration and labour market outcomes. This paper deals with this shortcoming by using a consistent estimator attained through Instrumental Variables methods for estimating the effect of the duration of a sick leave spell on post-sick leave earnings. I use Danish administrative data and a major 2001 reform of the sick leave system as the instrument for duration. I find that the duration of a sick leave spell has both short and long term effects on post-sick leave earnings.
分析病假持续时间对后续劳动力市场结果影响的研究并未考虑到持续时间与劳动力市场结果之间潜在的内生关系。本文通过使用工具变量方法获得的一致估计量来估计病假持续时间对病假后收入的影响，从而解决了这一缺陷。我使用丹麦行政数据和 2001 年病假制度的重大改革作为持续时间的工具。我发现，病假持续时间对病假后的收入既有短期影响，也有长期影响。
