This paper focuses on the following two primary reasons that employers use temporary contracts: to flexibly adjust employment and to screen workers. A search‐matching framework is used to not only address employers’ endogenous choices in using temporary contracts, but also numerically identify the situations in which these contracts are likely to be used as a screening tool for permanent positions. This numerical exercise demonstrates that reducing employment protections in permanent jobs, reducing benefits for unemployed workers and raising the conversion probability from temporary to permanent employment will increase the relative proportion of employers who use temporary contracts as a screening device.

摩擦性劳动力市场中雇主使用临时合同的决定因素

本文着眼于雇主使用临时合同的以下两个主要原因：灵活地调整就业和筛选工人。搜索匹配框架不仅用于解决雇主在使用临时合同时的内在选择，而且可以从数字上确定可能将这些合同用作永久职位筛选工具的情况。这项数字实验表明，减少永久性工作中的就业保护，减少失业工人的福利以及提高从临时性就业向永久性就业的转换可能性，将增加使用临时合同作为筛选工具的雇主的相对比例。
