摘要

本文考察了欧洲国家2019冠状病毒病大流行爆发一年后消费者失业不确定性的演变。由于不确定性不能直接观察到,我们使用两种替代方法来直接近似它。这两种方法都是基于从欧洲委员会进行的消费者调查中得出的定性期望。一方面,继Dibiasi和Iselin(2019)之后,我们使用了无法正式确定失业预期的消费者比例(奈特式不确定性)。另一方面,我们使用Claveria等人(2019)提出的几何差异指标来量化企业和消费者预期不一致的比例。我们使用了来自22个欧洲国家的信息。我们发现两个不确定度度量是协变的。尽管我们观察到各国之间存在明显差异,但在大多数情况下,对就业不确定性的看法在危机爆发前达到顶峰,在封锁的头几个月里急剧下降,并在过去几个月里开始再次上升。在对失业率进行协整检验时,我们发现在大多数国家,差异指标与失业率表现出长期关系,而奈特不确定性指标与失业率表现出纯粹的短期关系。这两个指标对失业的影响的特点是相当不对称,显示出对不确定性程度下降的更强烈反应。虽然这一发现乍一看似乎有悖常理,但它在某种程度上反映了这样一个事实:在经济衰退时期,消费者对就业预期的分歧程度会大幅下降。

Employment Uncertainty a Year after the Irruption of the COVID-19 Pandemic
This paper examines the evolution of consumer uncertainty about unemployment one year after the irruption of the covid-19 pandemic in European countries. Since uncertainty is not directly observable, we use two alternative methods to directly approximate it. Both approaches are based on qualitative expectations elicited form the consumer survey conducted by the European Commission. On the one hand, following Dibiasi and Iselin (2019), we use the share of consumers unable to formalize expectations about unemployment (Knightian-type uncertainty). On the other hand, we use the geometric discrepancy indicator proposed by Claveria et al. (2019) to quantify the proportion of disagreement in business and consumer expectations. We have used information from 22 European countries. We find that both uncertainty measures covary. Although we observe marked differences across countries, in most cases the perception of employment uncertainty peaked before the outbreak of the crisis, plummeted during the first months of the lockdown, and started rising again since the past few months. When testing for cointegration with the unemployment rate, we find that the discrepancy indicator exhibits a long- term relationship with unemployment in most countries, while the Knightian uncertainty indicator shows a purely short-run relationship. The impact of both indicators on unemployment is characterised by considerable asymmetries, showing a more intense reaction to decreases in the level of uncertainty. While this finding may seem counterintuitive at first sight, it somehow reflects the fact that during recessive periods, the level of disagreement in the employment expectations of consumers drops considerably.
