Permanent Jobs, Employment Protection, and Job Content
利用21个国家的成人能力调查数据，研究发现永久性工作比临时性工作涉及更多技能使用和任务自主权，且严格的就业保护法扩大了这一差距。
Using Programme for the International Assessment of Adult Competencies ( PIAAC ) data for twenty‐one countries, I study the impact of employment protection laws ( EPL ) on job content. I find that workers’ use of influence, reading, writing, planning, numeracy and information and computer technology skills, and their task discretion, were higher in permanent than in temporary jobs. Moreover, stricter EPL on permanent jobs raised the gap in job content for influence, reading, writing, and planning skills used in permanent jobs versus temporary jobs.
