A shortage of nurses is currently a problem in several countries, and an important question is therefore how one can increase the supply of nursing labour. In this paper, we focus on the issue of nurses leaving the public health sector by utilising a unique data set containing information on both the supply and demand side of the market. To describe the exit rate from the health sector we apply a semi-parametric hazard rate model. In the estimations, we correct for unobserved heterogeneity by both a parametric (Gamma) and a non-parametric approach. We find that both wages and working conditions have an impact on nurses' decision to quit. Furthermore, failing to correct for the fact that nurses' income partly consists of compensation for inconvenient working hours results in a considerable downward bias of the wage effect.
目前，护士短缺在多个国家都是一个问题，因此一个重要的问题是如何增加护理劳动力的供应。在本文中，我们利用一个独特的数据集，该数据集包含市场供需双方的信息，重点关注护士离开公共卫生部门的问题。为了描述卫生部门的离职率，我们应用了半参数风险率模型。在估计中，我们通过参数（伽马）和非参数方法对未观察到的异质性进行校正。我们发现工资和工作条件都会对护士的离职决定产生影响。此外，如果不考虑护士的收入部分包括对不便工作时间的补偿这一事实，工资效应会出现相当大的向下偏差。
