Decreasing Wage Mobility in the Low-Wage Sector - Increasing Genuine State Dependence or Composition Effects?

虽然关于东德工资不平等和流动性的许多经验证据都集中在统一后工资的演变上，但提供统一前时期证据的工作要少得多。在此背景下，本项目旨在研究东德统一前和从中央计划经济向市场经济过渡期间的工资流动性。特别强调的问题是，从中央计划经济到市场经济的过渡是否为那些在旧制度下在经济上相对贫穷的人提供了根本的新前景。以前对这个问题的实证研究受到了适当的代表性纵向微观数据的限制，这些数据能够跟踪不同政治和经济制度下个人的劳动力市场职业。我们利用德国养老金登记数据，最近已经成为可用的，并提供完整的纵向信息统一前和统一后的1%样本的养老金相关的个人传记，年龄在15至67岁，直到2007年。然后，我们继续探讨工人的低工资或高工资地位如何决定他们在转型后的工资和劳动力市场地位。特别令人感兴趣的是，在统一前时期，以及从中央计划经济向市场经济过渡期间和之后，德意志民主共和国低工资就业对国家的真正依赖程度。

While much of the empirical evidence on wage inequality and mobility in Eastern Germany has focused on the evolution of wages after unification, much less work has provided evidence on the pre-unification period. Against this background, this project aims to study wage mobility in Eastern Germany before unification and during the transition from a centrally planned to a market economy. Particular emphasis is given to the question of whether the transition from a centrally planned to a market economy offers fundamentally new perspectives for those who, in economic terms, were relatively deprived under the old regime. Previous empirical research on this question has been limited by the availability of suitable representative longitudinal micro-data that are able to track individuals' labour market careers across different political and economic regimes. We exploit German pension register data that recently have become available and provide full pre- and post-unification longitudinal information on the pension-relevant biographies of a 1%-sample of individuals aged 15 to 67 up to the year 2007. We then proceed to ask as to how workers' low or high-wage status determines their wage and labour market status after the transition. Of particular interest is the extent of genuine state dependence of GDR low-wage employment in the pre-unification period as well as during and after the transition from a centrally planned to a market economy.
