There is a large social and academic interest in income inequality and social mobility and its determinants. The empirical research of income inequality is largely based on aggregated macro data, studies on intergenerational social mobility on microdata. Studies on social mobility in a longer-run perspective are scarce, because a profound analysis requires very detailed individual data such as the year of birth, gender, educational qualifications and wages not only for the person him/herself, but also for the father and ideally other family members. Data like this is often incomplete, available only for short periods or small samples.This research project is based on all personnel files of the Machine Factory Esslingen (Maschinenfabrik Esslingen), which were created in the period from the establishment of the company in 1846 to its dissolution in 1965. In total there are about 10.000 files. This unique source can be used to study income inequality, living standards, working conditions and the social mobility of employees from workers to CEOs for a period over 100 years. In addition, it is possible to explore the macroeconomic perspective on the long-term development of income inequality and and the microeconomic analysis of the social mobility of individuals using one single case study.In addition, this previously untapped source contains unique personal information that is not accessible in modern sources because of privacy restrictions. In addition to information on marital status, gender, year of birth, etc., this includes further information on personal and /or family relationships within a career network, personal references and assessments of the work performance of previous employers and superiors as well as party and religious memberships. Based on this information, we will investigate whether and how formal and informal social networks influence social mobility and whether this relationship is tied to a certain institutional framework.

社会和学术界对收入不平等和社会流动性及其决定因素有很大的兴趣。对收入不平等的实证研究主要是基于宏观数据的汇总，而对代际社会流动性的研究主要是基于微观数据。从长期角度对社会流动性进行的研究很少，因为深入分析需要非常详细的个人数据，如出生年份、性别、教育资格和工资，不仅包括本人，还包括父亲，最好是其他家庭成员。这样的数据通常是不完整的，只能在短时间内或小样本中获得。本研究项目基于埃斯林根机械厂（Maschinenfabrik Esslingen）的所有人事档案，这些档案创建于1846年公司成立至1965年解散期间。总共有大约10000个文件。这一独特的数据来源可用于研究100多年来的收入不平等、生活水平、工作条件以及员工从工人到CEO的社会流动性。此外，通过一个案例研究，可以从宏观经济的角度探讨收入不平等的长期发展，并从微观经济的角度分析个人的社会流动性。此外，这一以前未开发的资源包含独特的个人信息，由于隐私限制，无法在现代来源中获得。除了婚姻状况、性别、出生年份等信息外，这包括关于职业网络中个人和/或家庭关系的进一步信息、个人推荐信、对前雇主和上级工作业绩的评估以及党派和宗教成员身份。基于这些信息，我们将研究正式和非正式的社交网络是否以及如何影响社会流动性，以及这种关系是否与某种制度框架有关。
