The regulation of occupations and its impact on individual labour market outcomes

近年来，关于职业对劳动力市场过程和不平等的影响的研究迅速恢复了重要性。对职业关闭的研究表明，职业有不同的监管模式，这些模式影响着劳动力市场的工资结构。然而，这一文献仅限于职业关闭过程；此外，还需要更准确地实施职业管制的经验性指标。在此背景下，本项目旨在以新的实证指标为基础，调查不同水平的职业监管对封闭以及劳动力市场中一般匹配和流动过程的影响。具体而言，我们探讨了以下研究问题：第一，职业调节是否促进了匹配过程？其次，监管机制是否限制了劳动力市场上的职业流动性，如果是，如何以及在多大程度上？最后，职业监管对个人劳动力市场结果的影响是什么？对于实证实施，我们计划使用IAB职位空缺调查（EGS）。EGS是德国唯一提供匹配过程的代表性和统计有效数据的调查。其次，我们打算使用综合劳动力市场传记样本（SIAB）。SIAB是在德国所有受社会保障保障的就业人员中抽取2%的样本。它的大量案例使我们能够在职业层面上进行有意义的分析。这两个数据集都特别适合回答概述的研究问题，但缺乏关于职业监管的信息。因此，我们通过衡量职业监管水平的指标来补充这些数据集。我们的分析基于描述职业制度特征的指标。为了检查它们与我们的研究问题的适用性，我们还希望整合职业监管的替代测量。因此，我们期望制作高水平的出版物，一方面有助于了解职业监管，另一方面有助于了解劳动力市场结果。其次，我们打算对职业法规的操作化及其对实证劳动力市场和不平等研究的适用性提供见解。第三，研究结果将对不同职业制度安排模式的劳动力市场政策有价值。

In recent years, research about the influence of occupations on labor market processes and inequality has recovered rapidly in importance. Studies on occupational closure have revealed that occupations have different modes of regulations which impact the wage structure in the labor market. This literature, however, is limited to occupational closure processes; additionally, empirical indicators which operationalize the regulation of occupations more accurately are needed.Against this background, this project aims to investigate on the basis of new empirical indicators the effect of different levels of occupational regulation on closure as well as on general matching and mobility processes in the labor market. Specifically, we investigate the following research questions: First, does the regulation of occupations facilitate the matching process? And, secondly, do regulatory mechanisms restrict occupational mobility on the labor market, and if so, how and to what extent? Finally, what are the consequences of occupational regulation on individual labor market outcomes?For the empirical implementation we plan to use the IAB Job Vacancy Survey (EGS). The EGS is the only survey in Germany which provides representative and statistically valid data on matching processes. Secondly, we intend to use the Sample of Integrated Labor Market Biographies (SIAB). The SIAB is a two percent sample of all persons whose employment is subject to social security in Germany. Its large number of cases enables us to conduct meaningful analyses at the occupational level. Both data sets are especially suitable to answer the outlined research questions, but lack information on occupational regulation. Therefore, we supplement these data sets by indicators that measure the level of occupational regulation. We base our analyses on indicators describing the institutional features of occupations. To check their suitability with regard to our research questions we also want to integrate alternative measurements of occupational regulation.As a result, we expect to produce high-level publications contributing to the knowledge about occupational regulation on the one hand and labor market outcomes on the other. Secondly, we intend to provide insights into the operationalization of occupational regulations and its suitability for empirical labour market and inequality research. Third, the results will be valuable for labour market policy with regard to different modes of institutional arrangements of occupations.
