Abstract

A lack of job security is an increasingly prevalent characteristic of modern labour markets, and there is evidence that recent financial crises have exacerbated this issue. In this paper, we assess how exogenous changes in the macroeconomic environment affect workers' perceived job security, and the impact of job security on measures of mental and physical health. To identify these effects, we exploit variation in world commodity prices over the period 2001–15, and analyse 15 waves of individual-level panel data that includes unusually detailed classifications of mining workers. We find that commodity price movements drive changes in perceived job security, which in turn significantly and substantively affects the mental health of workers. In contrast, we find no effects on physical health. Our results imply that the estimated welfare costs of recessions are substantially larger when the effects of job insecurity on the health of workers is considered.
世界商品价格、工作保障和健康:来自采矿业的证据
缺乏工作保障是现代劳动力市场日益普遍的特征,有证据表明,最近的金融危机加剧了这一问题。在本文中,我们评估了宏观经济环境的外生变化如何影响工人的感知工作保障,以及工作保障对心理和身体健康指标的影响。为了确定这些影响,我们利用了2001 - 2015年期间世界商品价格的变化,并分析了15波个人层面的面板数据,其中包括采矿工人异常详细的分类。我们发现,商品价格的变动驱动感知工作安全的变化,这反过来显著和实质性地影响工人的心理健康。相比之下,我们发现对身体健康没有影响。我们的结果表明,当考虑到工作不安全感对工人健康的影响时,经济衰退的估计福利成本要大得多。
