Wages, Heterogeneities, and Labor Market Dynamics

搜寻摩擦为匹配的工人和企业产生长期的雇佣关系和租金，这些在工资确定过程中共享。对工资形成和工资周期性的良好理解是解决各种问题的关键（例如，雇用和解雇决定，劳动力市场动态，工资分散），因此最终为政策（例如劳动力市场或商业周期政策）。在我们项目的头两年，我们已经创建了新的独特的行政工资和劳动力市场流动面板（AWFP）数据集，我们已经确定了许多关于工资形成的新的程式化事实，异质性和劳动力市场流动动态在德国。我们将这些程式化的事实与现有的理论（例如，在职求职）进行了对比，我们提供了新的理论框架（例如，关于不同的真实的工资周期及其对企业招聘行为的反馈），我们提供了统计解释（例如，关于任期回报）。我们的工作帮助我们确定了重要的未决问题和新的数据要求。我们的新项目提案旨在获得对企业招聘活动及其工资形成的新见解。为此，我们会将AWFP的数据与IAB职位空缺调查合并，后者包含有关职位空缺，招聘渠道和强度的信息。我们将建立新的程式化的事实，不同的工资周期和其他因素如何影响企业的搜索行为和空缺职位发布。我们还将分析企业如何从其他企业挖人。结果将与搜索理论进行对比。开发新的模型机制，并与数据结果进行比较。此外，我们将使用行政人员数据分析工资的统计特性和工资周期性在经济周期中的各种偏差。例如，我们将开发一种方法来控制时变匹配特定的异质性，并测试这是否会导致估计工资周期性的系统性偏差。计量经济学的结果将再次与理论进行对比。总的来说，我们的目标是建立新的程式化的事实。我们预计新的程式化事实将引起广大劳动经济学家的兴趣，因为它们将包含对工人重新分配和空缺职位发布行为的见解。此外，我们的目标是推进相关模式和机制。它们将使我们能够以结构性方式解释观察到的现象，并可用于政策分析。

Search frictions generate long-term employment relationships and rents for matched workers and firms, which are shared in the wage determination process. A good understanding of wage formation and wage cyclicality is key for a variety of issues (e.g. hiring and firing decisions, labor market dynamics, wage dispersion) and therefore ultimately for policy (e.g. labor market or business cycle policies).During the first two years of our project, we have created the new unique Administrative Wage and Labor Market Flow Panel (AWFP) dataset and we have identified many new stylized facts on wage formation, heterogeneities and labor market flow dynamics in Germany. We contrasted these stylized facts with existing theories (e.g. on-the-job search), we provided new theoretical frameworks (e.g. on different real wage cyclicalities and their feedback on establishments' hiring behavior) and we offered statistical explanations (e.g. on returns to tenure). Our work has helped us to identify important open questions and new data requirements.Our new project proposition aims at gaining new insights on the hiring activities of establishments and their wage formation. For this purpose, we will merge the AWFP data with the IAB Job Vacancy Survey, which contains information on vacancies, recruitment channels and intensities. We will establish new stylized facts on how different wage cyclicalities and other factors affect establishments' search behavior and vacancy posting. We will also analyze how establishments poach workers from other establishments. The results will be contrasted with search theory. New model mechanisms will be developed and compared to the data outcomes.Furthermore, we will use administrative worker data to analyze various biases when it comes to the statistical properties of wages and wage cyclicalities over the business cycle. We will for example develop a method to control for time-variant match-specific heterogeneity and test whether this leads to a systematic bias of estimated wage cyclicalities. The econometric results will again be contrasted with theory.Overall, we aim at establishing new stylized facts. We expect the new stylized facts to be of interest to a broad audience of labor economists because they will for example contain insights on worker reallocation and vacancy posting behavior. In addition, we aim at advancing relevant models and mechanisms. They will allow us to interpret observed phenomena in structural manner and can be used for policy analysis.
