Does Economic Uncertainty Have an Impact on Decisions to Bear Children? Evidence from Eastern Germany

Economic agents routinely face various types of economic uncertainty. Seldom have these various forms of uncertainty manifested themselves more sharply than in the transition economies of Central and Eastern Europe. In East Germany, the transition was especially rapid and sharp since East Germany virtually over night made the transition from the Eastern European system to the market economy of Western Germany. Uncertainties increased and many institutional and behavioral adjustments took place in a concentrated period of time. Among the latter was a sharp fall in fertility rates, leading to a growing literature on the explanation for this decline. This paper focuses directly on the link between uncertainty and childbearing decisions and examines the link at the micro level. It develops a stylized overlapping generations model showing that the relationship between economic uncertainty and childbearing decisions is not necessarily monotonic, and hence that the aforementioned inverse relationship is merely a testable hypothesis. It then uses GSOEP data for 1992 and 1996 to estimate the nature of this relationship, and concludes that while this relationship was indeed negative for East German women during these two years, the nature of uncertainty affecting their childbearing decisions differed across the years.

The effects of overeducation on productivity in Germany — the firms' viewpoint

Several firm-related aspects of employee productivity are analyzed using GSOEP data. The basic premise is that, as a consequence of frustration, overeducated employees are less productive than their correctly allocated colleagues. However, the results obtained in the present study contradict the few available empirical findings, all of which are based on data from the United States. When comparing employees working in jobs with similar levels of requirements (the sole approach which seems to be useful), overqualified employees are found to be healthier, more strongly work- and career-minded, more likely to participate in on-the-job training, and to have longer periods of tenure with the same firm than their correctly allocated colleagues. No significant differences could be determined with respect to job satisfaction. These findings are consistent with the established fact that overeducated workers receive wage premiums for their surplus schooling. The overall results make the hiring of overqualified applicants understandable, and could explain the employers' motivation to accept persistent overeducation in the labor force.
