Wages, Heterogeneities, and Labor Market Dynamics

搜索摩擦为匹配的工人和公司产生长期雇佣关系和租金，这些在工资决定过程中是共享的。对工资形成和工资周期性的良好理解是各种问题（例如雇用和解雇决定、劳动力市场动态、工资分散）的关键，因此最终对政策（例如劳动力市场或商业周期政策）至关重要。在我们项目的前两年，我们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，我们已经确定了德国工资形成，异质性和劳动力市场流动动态的许多新的风格化事实。我们将这些程式化的事实与现有理论（例如在职搜索）进行了对比，我们提供了新的理论框架（例如关于不同实际工资周期性及其对企业招聘行为的反馈），我们提供了统计解释（例如关于终身教职的回报）。我们的工作帮助我们确定了重要的开放问题和新的数据需求。我们的新项目主张旨在获得有关机构招聘活动及其工资形成的新见解。为此，我们会将AWFP数据与IAB职位空缺调查合并，后者包含有关职位空缺、招聘渠道和招聘强度的信息。我们将建立新的程式化事实，说明不同的工资周期性和其他因素如何影响机构的搜索行为和空缺发布。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。将开发新的模型机制，并与数据结果进行比较。此外，我们将使用行政人员的数据来分析在商业周期中工资的统计特性和工资周期性方面的各种偏差。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风格化事实。我们期望新的风格化的事实会引起广大劳动经济学家的兴趣，因为例如，它们将包含对工人再分配和职位空缺发布行为的见解。此外，我们还致力于推进相关模式和机制建设。它们将使我们能够以结构性的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.
