Search behavior of workers and firms and implications for matching outcomes

劳动力市场匹配是一个复杂的过程，它因阻碍工人和工作岗位有效重新分配的摩擦而变得缓慢。遵循搜索匹配方法的现有劳动力市场理论通常是根据个人收入历史数据或匹配的雇主-雇员数据集进行评估和测试的。然而，这些数据最终不足以了解减慢匹配形成的摩擦，并决定工人和公司的搜索行为。这个项目的目标是将几个工人和公司的数据联系起来，并使用它们来提供关于工人和公司匹配过程及其对劳动力市场动态的影响的新见解。具体地说，我们探索了关于公司招聘和工人求职战略的新的德国调查数据，并将这些数据与现有的管理数据集联系起来。在这些关联数据的帮助下，我们将开发和定量评估理论模型框架，以审查几个研究问题。首先，我们想要了解员工和公司对搜索渠道的选择及其对匹配结果的影响。其次，我们评估了雇主方面的招聘强度的不同方面，以及它们在当地劳动力市场和一段时间内对匹配效率的作用。第三，我们分析了当地劳动力和住房市场条件对区域劳动力市场搜索范围的影响，以及它们对工人和就业流动的影响。

Labor market matching is a complex process which is slowed down by frictions that impede the efficient reallocation of workers and jobs. Existing theories of the labor market following the search-and-matching approach are usually evaluated and tested on the basis of data on individual earnings histories or matched employer-employee datasets. However, these data are ultimately not sufficient to learn about the frictions that slow down match formation and determine the search behavior of both workers and firms. The goal of this project is to link several worker and firm data and to use them to provide new insights on the worker-firm matching processes and their implications for labor market dynamics. Specifically, we explore new German survey data about firms’ recruitment and workers’ job search strategies and link these data to existing administrative datasets. With the help of such linked data we will develop and quantitatively assess theoretical model frameworks in order to examine several research questions. First, we want to understand the choices of search channels by both workers and firms and their implications for matching outcomes. Second, we assess different dimensions of recruitment intensity on the employer side and their role for matching efficiency across local labor markets and over time. Third, we analyze the impact of local labor and housing market conditions for the regional scope of labor market search and their implications for the mobility of workers and jobs.
