In health economic evaluation studies, to value productivity loss due to absenteeism, existing methods use wages as a proxy value for marginal productivity. This study is the first to test the equality between wage and marginal productivity losses due to absenteeism separately for team workers and non-team workers. Our estimates are based on linked employer-employee data from Canada. Results indicate that team workers are more productive and earn higher wages than non-team workers. However, the productivity gap between these two groups is considerably larger than the wage gap. In small firms, employee absenteeism results in lower productivity and wages, and the marginal productivity loss due to team worker absenteeism is significantly higher than the wage loss. No similar wage-productivity gap exists for large firms. Our findings suggest that productivity loss or gain is most likely to be underestimated when valued according to wages for team workers. The findings help to value the burden of illness-related absenteeism. This is important for economic evaluations that seek to measure the productivity gain or loss of a health care technology or intervention, which in turn can impact policy makers' funding decisions.
在健康经济评估研究中，为了评估因旷工导致的生产率损失，现有方法使用工资作为边际生产率的替代值。本研究首次分别针对团队工作者和非团队工作者，检验了工资与因旷工导致的边际生产率损失之间的相等性。我们的估计基于来自加拿大的雇主-雇员关联数据。结果表明，团队工作者比非团队工作者生产率更高且工资更高。然而，这两组之间的生产率差距远大于工资差距。在小公司中，员工旷工导致生产率和工资降低，且团队工作者旷工导致的边际生产率损失显著高于工资损失。大公司不存在类似的工资-生产率差距。我们的研究结果表明，根据工资来评估团队工作者的生产率损失或收益时，很可能会被低估。这些发现有助于评估与疾病相关的旷工负担。这对于旨在衡量医疗技术或干预措施的生产率收益或损失的经济评估很重要，而这反过来又会影响政策制定者的资金决策。
