Data for: The role of the informal sector in the early careers of less-educated workers

Abstract of associated article: Does work experience gained in the informal sector affect the career prospects of less-educated workers? This paper examines two roles that informal sector jobs play in the early stages of a worker's career: informal jobs may (i) provide the opportunity to accumulate skills, and (ii) act as a screening device that enables employers to learn a worker's ability. The paper develops a matching model of the informal and formal sectors that can accommodate both roles. Implied hazard rates from informal to formal sectors as a function of tenure are shown to differ depending on the role of informal sector jobs: human capital accumulation or screening. Using the ENOE, a longitudinal employment survey from Mexico, hazard functions are estimated for less-educated workers. The estimated hazard functions indicate that informal sector jobs play an important role by screening young less-educated workers.相关研究论文摘要：非正规部门所获工作经历是否会对低学历劳动者的职业发展前景产生影响？本文探讨了非正规部门岗位在劳动者职业早期阶段所承担的两种核心作用：其一，这类岗位可为劳动者提供技能积累的契机；其二，其可作为筛选机制，助力雇主了解劳动者的能力水平。本文构建了可兼容这两种作用的非正规与正规部门匹配模型。研究表明，以在职时长为自变量、由模型推导得出的非正规部门向正规部门转移的风险率，会因非正规部门岗位的作用（技能积累或筛选）而呈现显著差异。本文依托墨西哥纵向就业调查ENOE，对低学历劳动者的转移风险函数进行了估计。最终估计得到的风险函数结果显示，非正规部门岗位通过筛选年轻低学历劳动者发挥了重要作用。
