The role of tasks, contractual arrangements, and job composition in explaining the dynamics of wage inequality: Evidence from France
利用2005-2016年法国工人数据，发现合同和工作安排是工资不平等的主要驱动因素，而任务内容和组织方法影响较小，质疑了常规任务偏向技术变革假设的普适性。
The paper examines wage differentials in France over time, analysing the impact of various covariates at different points on the wage distribution scale. We simultaneously assess multiple potential explanatory factors, including the tasks performed by workers, organizational methods, contractual arrangements, and individual characteristics. To accomplish this, we utilize a unique worker-level database, the French Enquête Complémentaire Emploi: Conditions de travail, covering the period from 2005 to 2016. Our primary findings support the hypothesis that shifts in wage differentials across the wage distribution can be predominantly attributed to contractual and work arrangements, as opposed to tasks and organizational practices. Job composition and contractual arrangements emerge as pivotal factors in understanding the determinants and patterns of wage inequality among workers. In contrast, tasks' content and organizational methods appear to play a relatively minor, if any, role. In sum, the evidence presented in this article suggests that the RBTC hypothesis may not be generalised across countries. It underscores the importance of considering structural and institutional factors, particularly in countries characterized by highly regulated labour markets and a strong tradition of industrial relations.
