Precarious employment and regional mobility: An experimental study using a factorial survey design

这项提议的目的是将DFG资助的不稳定就业和区域流动项目的成功工作延长一年：使用析因调查设计(AU394/1-1和AB111/8-1)的实验研究。该项目的主要目的是检验劳动力市场研究和家庭社会学关于工作特征(如收入、定期合同、地区距离)对接受新的(区域间)工作机会的意愿的影响的理论。因此，这是第一次使用实验设计。研究小组在一波关于劳动力市场和社会保障(PASS)的小组研究中实施了一个因子调查模块(FSM)，其中包括五个假设性的工作机会。使用这种实验方法可以比较受访者(N=4.813)在不同工作特征条件下接受工作的情况，同时避免现有研究面临的选择性问题。与真实的劳动力市场不同，试验性的FSM中的工作机会是随机分配给受访者的。这使得可以隔离工作特征的影响，并估计权衡(如收入增长和工作保障之间的影响)，而不会因未观察到的异质性而产生偏见。在第一个供资期间，按预期完成了全面的数据准备和出版工作。这次更新的目的是实现进一步的数据准备和分析，重点放在PASS数据集的纵向方面，并解决在第一个供资期间查明的研究差距。有四个研究问题特别令人感兴趣：区域环境(例如区域失业率或儿童保育情况)在多大程度上影响受访者接受工作机会？之前的流动性和伙伴关系经历对工作机会的接受有什么影响？因子调查模块的数据具有较高的外部效度吗？工作特征，比如固定期限合同，对于评估工作机会有多重要？

The purpose of this proposal is the one year extension of the successful work in the DFG-funded project Precarious employment and regional mobility: An experimental study using a factorial survey design (AU394/1-1 und AB111/8-1). The main aim of this project is to test theories from labour market research and sociology of the family with regard to the influence of job characteristics (e.g. income, fixed-term contracts, regional distance) on the willingness to accept a new (interregional) job offer. Therefore for the first time an experimental design is used. The research team implemented a factorial survey module (FSM) with five hypothetical job offers in one wave of the panel study Labour market and social security (PASS). Using such experimental method allows comparing the job offer acceptance of respondents (N = 4.813) conditional on various job characteristics, while avoiding the selectivity issues existing research is suffering from. In contrast to real labour markets, job offers in the experimental FSM are randomly allocated to respondents. This allows isolating the effects of job characteristics and estimating trade-offs (like those between gains of income and job security) without bias by unobserved heterogeneity. During the first funding period comprehensive data preparation and publication was achieved as intended. The aim of this renewal is to achieve further data preparation and analyses that focus on the longitudinal aspect of the PASS data set and address research gaps that were identified during the first funding period. Four research questions are of particular interest: To what extent do regional contexts (e.g. regional unemployment rates or childcare situations) influence respondents' job offer acceptance? What effect has the previous mobility- and partnership-biography on job offer acceptance? Do data from the factorial survey module hold a high external validity? How important are job characteristics, like fixed-term contracts, for the evaluation of job offers?
