Workers and Firms Sorting into Temporary Jobs
构建了一个包含临时和永久合同的失业匹配模型，并用意大利数据验证了临时工作能缩短非就业期的理论预测。
The liberalisation of temporary contracts has led to a sizeable share of jobs covered by temporary contracts. This article proposes a matching model of unemployment in which temporary (fixed‐term) and permanent (open‐ended) jobs coexist in a long‐run equilibrium. From the labour demand standpoint, the choice of the type of contract leads to a trade‐off between an ex‐ante speed of hiring and an ex‐post flexible dismissal rate. Empirically, we test with Italian longitudinal data whether non‐employment spells that lead to a temporary job are shorter on average. The empirical evidence strongly supports our theoretical prediction.
