This study analyses the relationship between flexible employment, productivity and wages, along their distributions. We use an original firm-level dataset, which combines information on workplace characteristics from Rilevazione su Imprese e Lavoro (RIL) with the Analisi Informatizzata delle Aziende Italiane (AIDA) balance sheet information for the universe of Italian non-agriculture/financial corporations. We employ different quantile regression models to panel data and find, first, that use of temporary contracts is associated to a reduction in labour productivity and wages at each point in the corresponding distribution; and second, that the negative relationship between labour productivity and wages decreases in magnitude along the quantiles of the productivity and wage distributions, suggesting that low-productive/low-wage firms use temporary employment to permanently staff positions and to compress labour costs.

本研究分析了灵活就业、生产力和工资之间的关系及其分布。我们使用原始的公司级数据集，该数据集结合了来自Rilevazione su Imprese e Lavoro (RIL) 的工作场所特征信息和Analisi Informatizzata delle Aziende Italiane(AIDA) 意大利非农业/金融公司的资产负债表信息。我们对面板数据采用不同的分位数回归模型，并发现，首先，使用临时合同与相应分布中每个点的劳动生产率和工资的降低有关；其次，劳动生产率与工资之间的负相关关系随着生产率和工资分布的分位数而减小，这表明低生产率/低工资的公司使用临时就业来固定员工职位并压缩劳动力成本。
